I. From the Perspective of the Product Itself
(1) Specification Parameters
NYCWY copper wire screen cable has rigorous and detailed settings in terms of specification parameters, fully covering the power transmission needs in different application scenarios.
Its cross-sectional specifications are diverse, including 25mm², 35mm², 50mm², 70mm², and 120mm². The determination of this series of specifications is not arbitrary but based on in-depth research and accurate calculation of power demand in various industries. The 25mm² cable has excellent current-carrying capacity, which can meet the power supply needs of small and medium-power equipment such as small motors and building lighting. Its safe current-carrying capacity can reach a certain value, which fluctuates according to different laying environments. When laid in the air, the current-carrying capacity is approximately [X]A, and when laid underground, it is approximately [X]A. The 35mm² cable further improves the current-carrying capacity on the basis of 25mm². The current-carrying capacity when laid in the air is about [X]A, and when laid underground, it is about [X]A, which is suitable for power supply of slightly larger power equipment, such as some medium-sized industrial machinery.
The 50mm² cable has a larger current-carrying capacity, with about [X]A when laid in the air and [X]A when laid underground, which can meet the power transmission needs of some equipment in industrial production lines. The
70mm² Cable has a significant increase in current-carrying capacity, with about [X]A when laid in the air and [X]A when laid underground, and is often used in scenarios such as the connection of small and medium-sized transformers. The 120mm² cable, as a high-power specification in this series, has a current-carrying capacity of up to [X]A when laid in the air and about [X]A when laid underground, which is sufficient to meet the power needs of high-power scenarios such as large equipment, main lines of high-rise buildings, and new energy charging piles.
In addition to cross-sectional specifications and current-carrying capacity, other physical parameters of the cable are also important. The outer diameter of the cable increases with the increase of cross-sectional specifications. The outer diameter of the 25mm² cable is about [X]mm, 35mm² is about [X]mm, 50mm² is about [X]mm, 70mm² is about [X]mm, and 120mm² is about [X]mm. This outer diameter design not only ensures the reasonable layout of the internal structure of the cable but also facilitates installation in different laying environments.

In industrial automated production lines, a large number of small motors, sensors, and control equipment require stable power supply and signal transmission. These cables can not only provide reliable power for small motors but also ensure the accurate transmission of control signals in the secondary control circuit. Since there are various electromagnetic devices in the industrial environment, which are prone to electromagnetic interference, the copper wire shielding layer of the cable can effectively resist these interferences, ensure the stability of control signals, and thus ensure the normal operation of the production line.
In terms of building power distribution, cables of different specifications have their own uses. 25mm² and 35mm² cables are suitable for lighting systems in buildings, which can meet the lighting power needs of both ordinary residential buildings and large commercial complexes. 50mm² and 70mm² cables are often used for power distribution in buildings, such as power supply for air conditioners, elevators and other equipment. The 120mm² cable serves as the main line of high-rise buildings, undertaking the main power transmission task of the entire building. Its large cross-section and high current-carrying capacity can meet the needs of a large number of electrical equipment in high-rise buildings.
The rail transit field has extremely strict requirements on cable performance, and NYCWY copper wire screen cable can also adapt well. In metro, light rail and other rail transit systems, cables need to withstand frequent vibrations, temperature changes, electromagnetic interference and other tests. The 50mm² and 70mm² specifications of this series of cables can be used for internal power supply and control lines of rail vehicles, while the 120mm² specification can be used for power supply systems along the track to provide stable power support for the normal operation of trains. Its excellent shielding performance can ensure smooth communication between the train control system and the outside world, avoiding safety accidents caused by electromagnetic interference.
In communication systems, the stable transmission of signals is crucial. The high shielding efficiency of NYCWY copper wire screen cable makes it an ideal choice for communication base stations, data centers and other places. In these places, a large number of communication equipment and lines are densely distributed, and the electromagnetic environment is complex. The cable can effectively block external interference, ensure the clarity and stability of communication signals, and ensure the normal operation of the communication system.
The new energy field is also an important application position for this cable. With the popularization of new energy vehicles, the construction of charging piles is increasing. The 120mm² cable can meet the high-power power transmission needs of charging piles and provide a reliable guarantee for the fast charging of new energy vehicles. At the same time, in new energy power generation systems such as solar power generation and wind power generation, the cable can also be used for power collection and transmission, and its environmental resistance can adapt to various harsh outdoor conditions.
(3) Material and Style
NYCWY copper wire screen cable is Strive for perfection in material selection, and the style design also fully considers the needs of different application scenarios.
The conductor is made of high-purity electrolytic copper with a purity of more than 99.9%. This high-purity copper has excellent conductivity, which can effectively reduce resistance and reduce energy loss during power transmission. Compared with ordinary copper materials, high-purity electrolytic copper has more uniform crystallization and extremely low impurity content, thus ensuring the stability and reliability of the cable during long-term use.
The insulation layer is made of materials with excellent temperature resistance, such as cross-linked polyethylene (XLPE). This material has good aging resistance and can maintain stable insulation performance in the temperature range of -40℃ to 90℃. At the same time, it also has excellent chemical corrosion resistance, which can resist the erosion of various chemical substances such as acid, alkali and oil, ensuring the safe operation of the cable in complex chemical environments.
The shielding layer adopts a tightly braided copper wire structure, and the diameter and braiding density of the copper wire are carefully designed. The selection of copper wire diameter ensures the mechanical strength of the shielding layer without excessively increasing the weight and outer diameter of the cable. The reasonable control of braiding density ensures that the shielding efficiency is as high as 90% or more, which can effectively block the intrusion and leakage of electromagnetic interference.
The outer sheath material is made of polyvinyl chloride (PVC) or polyethylene (PE) with good mechanical properties and environmental resistance.
PVC Sheath has high hardness and wear resistance, which is suitable for some scenarios with high requirements on sheath strength; PE sheath has better
Flexibility and low-temperature resistance, and performs better in cold areas or environments that need frequent bending.
In terms of style, cables are divided into single-core and
Multi-Core. Single-
Core Cables have a simple structure and are suitable for some simple power transmission scenarios;
Multi-Core Cables integrate multiple
Insulated Wire cores, wrapped with shielding layer and outer sheath, and are suitable for complex systems that need to transmit power and signals at the same time, such as industrial automation control lines and communication systems. In addition, according to different laying methods and environmental requirements, cables can also be divided into armored and non-armored styles.
Armored Cables add a layer of metal armor outside the sheath, such as
Steel Tape or steel wire armor, which can significantly improve the cable's resistance to mechanical damage and pressure, and are suitable for scenarios prone to external impact such as underground laying and bridge laying; non-armored cables are lighter in weight and more flexible, suitable for indoor laying, pipeline laying and other environments.
(4) Production Process
The production process of NYCWY copper wire screen cable strictly follows high-standard process requirements, and every link is precisely controlled.
The production of conductors adopts wire drawing and annealing processes. First, high-purity electrolytic copper billets are drawn into copper wires of the required diameter through wire drawing dies. During the wire drawing process, the drawing speed and the precision of the dies must be strictly controlled to ensure the uniform diameter of the copper wires. Then, the copper wire is annealed. Through high-temperature heating, the internal structure of the copper wire is changed, the internal stress generated during the wire drawing process is eliminated, and the flexibility and conductivity of the copper wire are improved.
The extrusion of the insulation layer adopts advanced extrusion molding technology. After the insulating material is heated and melted, it is uniformly coated on the surface of the conductor through an extruder to form a continuous insulation layer. During the extrusion process, the extrusion temperature, speed and pressure must be accurately controlled to ensure that the thickness of the insulation layer is uniform, the surface is smooth, and there are no defects such as bubbles and impurities. For cross-linked polyethylene insulation layers, cross-linking treatment is also required. Through heating or radiation, the polyethylene molecules undergo cross-linking reactions to form a three-dimensional network structure, thereby improving their temperature resistance and mechanical strength.
The shielding layer is braided with a special braiding machine. The copper wire must maintain a constant tension during the braiding process to ensure uniform braiding density. The rotation speed of the braiding machine and the feeding speed of the copper wire are precisely adjusted to make the interweaving of copper wires tight without loosening or missing braiding. After braiding, the shielding layer must be inspected to ensure that its shielding efficiency meets the requirements.
The extrusion process of the sheath is similar to that of the insulation layer, but the process parameters need to be adjusted according to the characteristics of the sheath material. During the extrusion process, it is necessary to ensure that the sheath and the shielding layer are tightly combined without gaps to prevent the intrusion of moisture, dust and other impurities. For armored cables, armor treatment is also required before sheath extrusion. Metal strips or wires are wrapped around the shielding layer in a certain way to form an armor layer.
Throughout the production process, there are also perfect quality inspection equipment and strict inspection procedures. After each process is completed, various parameters of the cable must be inspected, such as conductor diameter, insulation layer thickness, shielding layer density, sheath thickness, etc. The finished cable also needs to undergo multiple performance tests such as voltage resistance test, insulation resistance test, tensile test, bending test, etc., to ensure that each batch of cables meets relevant standards and regulations.
II. From the Perspective of General Product Information
(1) Packaging
The packaging design of NYCWY copper wire screen cable fully considers the protection, transportation and storage needs of the product.
For small-sized and short-length cables, hard cardboard reels are usually used for packaging. The size of the cardboard reel is designed according to the diameter and length of the cable to ensure that the cable can be tightly wound on it to avoid loosening and mutual friction during transportation. Both sides of the cardboard reel are equipped with baffles to prevent the cable from slipping off from both sides of the reel. After the cable is wound, the entire cardboard reel is wrapped with plastic film to play a role in moisture-proof and dust-proof.
For large-sized and long-length cables, iron-wood structure cable reels are used for packaging. This kind of cable reel is composed of a wooden disc and a metal frame, which has high strength and bearing capacity and can bear the winding of heavy cables. The design of the metal frame is convenient for the operation of forklifts and other handling equipment, improving loading and unloading efficiency. After the cable is wound on the iron-wood reel, it is also moisture-proof and dust-proof. For cables used in some special environments, warning signs such as moisture-proof, sun-proof, and shock-proof are marked on the packaging.
The packaging also clearly marks the relevant information of the product, such as product name, model specification, length, weight, production batch number, implementation standard, manufacturer, etc. This information helps users quickly identify and check the product during receipt and use, and also facilitates the manufacturer to carry out quality traceability.
In addition, to meet the needs of international transportation, the packaging of some exported cables will comply with international packaging standards, using fumigated wooden packaging to avoid the spread of pests and diseases. The strength and stability of the packaging will also be adjusted according to different transportation methods (such as sea transportation, land transportation, air transportation) to ensure that the cables are intact during long-distance transportation.
(2) Transportation

Road transportation has the advantages of high flexibility and door-to-door service, and is suitable for short-distance transportation and small batches of goods; railway transportation has large capacity and low cost, and is suitable for medium and long-distance transportation and large batches of goods; waterway transportation has lower cost and is suitable for long-distance and large batches of goods transportation, especially export products; air transportation is fast and suitable for emergency goods transportation, but the cost is relatively high.
During transportation, the cables need to be properly fixed. No matter which transportation mode is adopted, the cable reels must be firmly fixed on the transportation tool to prevent sliding and collision due to bumps, turns, etc. during driving. For multi-layer stacked cable reels, buffer materials such as wooden boards and rubber pads should be placed between layers to avoid damage caused by mutual extrusion.
Protective measures also need to be paid attention to during transportation. Cables should avoid direct sunlight, rain and snow cover to prevent aging and moisture of the insulation layer and sheath. In high-temperature seasons, sunshade measures should be taken; in cold seasons, for cables with poor cold resistance, thermal insulation measures should be taken. At the same time, the cable should be avoided from severe impact and vibration to prevent conductor breakage, insulation layer damage and other situations.
There should be special personnel responsible for escorting during transportation. The escorts should be familiar with the characteristics and transportation requirements of the cables, and regularly check the fixing of the cables and the integrity of the packaging. If any abnormal situation is found, measures should be taken in time to deal with it and report to the relevant departments.
