I. Information Related to the Product Itself
(I) Specification Parameters
The Nayby Na2xby 240mm
Aluminum Core cross - linked polyethylene (XLPE) 4 - core armou
Red PVC Insulated Cable is a cable product specially designed for specific power transmission needs. Its core specification parameters have clear pertinence and practicability.
The cable is designed with
4 Cores, and the conductor cross - sectional area of each core is 240mm². This specification means that it can carry a large current. Tests show that under standard working conditions, its continuous current - carrying capacity can meet the needs of medium and high - power power transmission and is suitable for a variety of medium and high - load power consumption scenarios.
As one of its important characteristics, the armoured structure also has corresponding specification standards. The thickness and material distribution of the armoured layer are accurately calculated, which not only ensures the protective performance but also does not excessively increase the weight and outer diameter of the cable. The overall outer diameter of the cable is optimally designed. On the premise of meeting various performances, the size is reduced as much as possible, which is convenient for passing through facilities such as pipes and cable trays in various laying environments.
In addition, the insulation thickness of the cable also meets relevant standards. The combination of
PVC Insulation layer and cross - linked polyethylene material makes the cable perform excellently in electrical performance, with high insulation resistance and low dielectric loss, which can effectively reduce the risk of electric leakage and ensure the safety of power transmission.
(II) Characteristic Uses
Based on its unique performance combination, this cable has distinct characteristic uses. In the industrial field, it is an ideal power supply choice for large - scale production equipment and production lines in industrial plants. There are many equipment in the industrial environment with large power, and there may be problems such as mechanical collision and dust. The armoured structure of the cable can resist mechanical impact, and the 4 - core specification of 240mm² can carry a large current to meet the power demand of industrial equipment.
It performs well in underground laying scenarios. The underground environment is complex and may face problems such as soil pressure, groundwater erosion and damage from underground organisms. The armoured layer of the cable can effectively resist the extrusion of soil and the impact of external objects. The corrosion resistance of PVC
Insulation Material and cross - linked polyethylene material can cope with the erosion of groundwater and so on, ensuring long - term stable power transmission underground, and is suitable for power supply of underground distribution trunk lines and underground pipe corridors, etc.
It also excels in humid environments, such as sewage treatment plants and aquaculture bases. These places have high air humidity and may have certain corrosive substances. The insulation and protective materials of the cable can resist humidity and corrosion, ensuring uninterrupted power supply.
In areas with many obstacles, such as construction sites and mines, there may be various construction materials and mechanical equipment stacked on the ground, and the cable is easy to be collided and crushed during laying. Its armoured structure can provide reliable mechanical protection to prevent the cable from being damaged by external obstacles and ensure that power transmission is not affected.
At the same time, in some civil fields with high requirements for the stability and safety of power transmission, such as the distribution trunk lines of large residential communities, the cable can also play an important role in providing stable guarantee for residents' domestic electricity.
(III) Material and Style
Conductor Material: The cable uses aluminum as the conductor material. Aluminum has good electrical conductivity. Although its conductivity is slightly lower than that of copper, it can fully meet the requirements of power transmission in the designed application scenarios of the cable. Moreover, the density of aluminum is low, which makes the overall weight of the cable relatively light. This advantage is particularly obvious during laying and installation, which can reduce the construction difficulty and cost. The Aluminum Conductor treated by special processes has a smooth surface and low impurity content, which further improves the conductivity and stability.
Insulation and Related Materials: The insulation part uses a combination of PVC and cross - linked polyethylene materials. PVC Insulation Material has good insulation performance, chemical corrosion resistance and mechanical strength, which can effectively insulate the current and protect the conductor. Cross - linked polyethylene material has excellent high - temperature resistance and electrical performance, and can maintain a stable insulation effect at higher temperatures. The combination of the two materials enables the cable to work stably in different temperatures and environments.
The armoured layer is made of high - quality metal materials, usually steel strips or steel wires. These materials have the characteristics of high strength and wear resistance, and can provide solid mechanical protection for the cable to resist external extrusion, collision and gnawing by rodents.
Style Design: The cable adopts an overall circular structure design. This style is not only beautiful, but more importantly, it can make the cable evenly disperse pressure when stressed, improving the compressive performance of the cable. The armoured layer tightly wraps around the outside of the cable, forming an organic whole with the inner insulation layer and conductor, which not only ensures the protective effect, but also does not affect the Flexibility of the cable. During laying, the cable can be bent to a certain extent to meet the needs of different laying paths, and the circular structure is also convenient for the storage and transportation of the cable.
(IV) Production Process
The production process of this cable integrates a variety of advanced technologies and strict quality control processes to ensure the high quality of the product.
In the conductor manufacturing link, high - purity aluminum materials are selected. Aluminum ingots are drawn into
Aluminum Wires with the required diameter through a wire drawing process, and then multiple
Aluminum Wires are stranded to form a 240mm² conductor through a stranding process. During the stranding process, the stranding pitch is strictly controlled to ensure the roundness of the conductor and the uniformity of its conductive performance.
When making the insulation layer, first, the PVC material is pretreated to remove impurities, and then it is evenly extruded and wrapped on the surface of the conductor through an extruder to form the insulation layer. During the extrusion process, the temperature, pressure and extrusion speed are accurately controlled to ensure that the insulation layer has a uniform thickness, a smooth surface and is closely combined with the conductor. After that, the relevant parts of cross - linked polyethylene are treated under specific conditions to form a stable molecular structure and improve the high - temperature resistance and other properties.
The armouring process is one of the key steps in the production of the cable. The armoured layer is made by using a special armouring machine to wrap metal strips or metal wires around the outer layer of the cable in a specified way. During the wrapping process, the wrapping tension and density are well controlled to ensure that the armoured layer is tight and flat, which can not only provide effective protection, but also not cause damage to the internal structure.
Finally, an overall inspection and test are carried out. The electrical performance and mechanical performance of the cable are comprehensively tested, such as insulation resistance test, voltage withstand test, tension test, etc. Only products that pass all tests can leave the factory.
II. General Product Information
(I) Packaging
The packaging link is carefully designed to ensure the integrity of the cable during transportation and storage.
The cable uses wooden or iron reels as the main packaging carriers. The wooden reels are made of high - quality hardwood and undergo drying treatment to avoid deformation due to moisture during transportation and storage. The iron reels are welded with high - strength steel, which is strong and durable and can bear a large weight.
The length of each reel of cable is determined according to the actual needs and transportation convenience, usually a certain standard length, such as 100 meters, 200 meters, etc. When winding the cable, ensure that the cable is arranged neatly to avoid twisting and extrusion, and reduce the wear of the cable in the package.
The outside of the package will be wrapped with a layer of waterproof plastic film to prevent rain and moisture from entering. At the same time, the product model, specification, length, production date, manufacturer and other information are clearly marked on the package for easy identification and traceability. For export or long - distance transportation products, necessary marks such as moisture - proof, sun - proof, handle with care and other warning signs will be added on the package.
(II) Transportation
Standardized operation during transportation is an important link to ensure the quality of the cable.
In terms of transportation mode selection, it is determined according to the transportation distance, quantity and customer needs. For short - distance transportation, truck transportation is usually adopted. The truck compartment should be kept clean and dry to avoid the cable from contacting sharp objects. For long - distance transportation, railway or container transportation can be chosen, which can better ensure the stability of the transportation process.
During transportation, the cable reels should be fixed firmly to prevent rolling and collision during transportation. When stacking, attention should be paid to the stacking height and method to avoid excessive pressure on the bottom cable reels and damage. At the same time, the cable should be prevented from being exposed to direct sunlight, rain and extreme temperatures. Sunshade measures can be taken in high temperature in summer, and attention should be paid to frost prevention in low temperature in winter.
During loading and unloading, special hoisting equipment is used, and the hoisting points are selected reasonably to avoid deformation of the cable reels or damage to the cables. Rough loading and unloading are strictly prohibited to ensure that the cable remains intact in all links of transportation.
