I. Information Related to the Products Themselves
(I) Specification Parameters
The
Power Cable models such as Cyy, Cyy - F, Nyy - J, Cyey, Cyey - F, Cyeaby - F, Cyeaby, and Cyaby each have their own focuses in terms of specification parameters, but all comply with relevant power transmission standards.
In terms of current - carrying capacity, cables of different models vary due to differences in structure and materials. Generally speaking, conventional models like Cyy and Nyy - J can meet the electricity demand of ordinary buildings. For example, in a 25℃ environment, a
Cyy Cable with a cross - section of 10mm² has a current - carrying capacity of about 30 - 40A; while models such as Cyey and Cyaby, which are suitable for industrial environments, have relatively larger current - carrying capacities. A Cyey cable with a 10mm² cross - section can have a current - carrying capacity of up to 40 - 50A. Flame - retardant models with "-F" may have slightly different current - carrying capacities compared to non - flame - retardant models of the same cross - section due to the particularity of sheath and other materials, but they can still meet the power transmission needs of corresponding scenarios.
The outer diameter of the cable also changes with the model and cross - section. Taking a 10mm² cross - section as an example, the outer diameter of a Cyy cable is about 12 - 15mm; the outer diameter of a Cyey cable may be slightly larger, about 14 - 17mm, due to the optimization of the insulation and sheath structure. Such outer diameter sizes facilitate laying in spaces such as walls and pipes. Their rated voltage is mostly 0.6/1kV, and some models can reach higher voltage levels according to requirements, being able to adapt to power transmission scenarios from low voltage to medium voltage.
(II) Characteristic Uses
These power cable models play important roles in different scenarios by virtue of their respective performance characteristics, with distinct characteristic uses.
The Cyy and Nyy - J models are suitable for regular wiring in ordinary buildings. In residential buildings, they can be used for power distribution from the distribution box to each household, meeting the electricity needs of common household appliances such as refrigerators, TVs, and air conditioners; in office buildings, they can provide stable power for office equipment like computers, printers, and lighting systems, and their stable transmission performance can ensure the normal operation of office equipment.
The Cyey and Cyaby models are suitable for industrial environments with higher requirements for insulation and sheath performance. In the production lines of small factories, they can be connected to various processing equipment such as milling machines and drilling machines, resisting the impact of possible oil stains, slight dust, etc. in the workshop on the cables; in the power distribution system of warehouses, they can adapt to the dry or humid environment of the warehouse, ensuring the uninterrupted power supply for equipment such as refrigeration and ventilation needed for goods storage.
Flame - retardant models with "-F", such as Cyy - F, Cyey - F, and Cyeaby - F, are suitable for places with dense crowds and high fire risks. In shopping malls, they can be used to connect systems such as central air conditioners, elevators, and lighting. Even in case of accidents, they can delay the spread of fire and gain time for personnel evacuation; in hospitals, they can ensure the power supply of medical equipment in operating rooms and wards, and the flame - retardant feature reduces the interference of fire on medical order.
The Nyy - J model has more advantages in some scenarios with higher requirements for stability due to its specific structural optimization. For example, in school laboratories, it can provide stable power for precision instruments, reducing instrument failures caused by cable problems.
(III) Material and Style
Power cables of different models are matched with their respective application scenarios in terms of material selection and style design.
In terms of materials, some models such as Cyey and Cyeaby use cross - linked polyethylene (XLPE) as the
Insulation Material. XLPE insulation has good temperature resistance, with a long - term working temperature of up to 90℃, which can withstand higher temperatures during peak electricity consumption and reduce insulation aging; at the same time, it has high insulation resistance and low power transmission loss. Models like Cyy and Nyy - J may use polyvinyl chloride (PVC) insulation, which can meet the insulation performance requirements of conventional scenarios and has a relatively low cost.
In terms of sheath materials, most models adopt
PVC Sheaths, which have strong corrosion resistance and mechanical protection capabilities. In humid basements and environments with slight acid and alkali, the PVC sheath can protect the internal wire cores from damage. For flame - retardant models with "-F", their sheaths may be added with flame retardants, which are not easy to burn when exposed to fire and can prevent the spread of flame along the cable.
In terms of style, these cables are mostly multi - core structures, with common ones being 2 - core, 3 - core, 4 - core, etc., which can be selected according to electricity needs. The appearance color is mostly black or gray, which is not only resistant to dirt but also can blend with various environments. The surface of the cable is clearly printed with marks such as model, cross - section, rated voltage, and manufacturer, facilitating identification and later maintenance.
(IV) Production Process
The production processes of these power cables are adjusted according to the characteristics of the models to ensure that the product performance meets the requirements of the corresponding scenarios.
For models with XLPE insulation, such as Cyey and Cyeaby, cross - linking treatment is required during the production process. First, the XLPE material is heated and melted, coated on the wire core through an extruder, and then cross - linking is carried out. Cross - linking can adopt the chemical cross - linking method. Under specific temperature and pressure, the XLPE molecules form a three - dimensional network structure to enhance the insulation performance.
For models with
PVC Insulation and sheaths, such as Cyy and Nyy - J, the extrusion process is crucial. The PVC material is heated to a molten state in the extruder and uniformly coated on the wire core or outside the insulation layer. During production, the extrusion temperature must be strictly controlled, generally between 150 - 180℃, to ensure that the insulation and sheath have uniform thickness and smooth surfaces.
In the production of flame - retardant models with "-F", flame retardants are added to the sheath material and mixed evenly. During the extrusion process, it is necessary to ensure that the flame retardants are evenly distributed to achieve the expected flame - retardant effect. During cabling, the wire cores are stranded according to the number of cores. If necessary, filling materials are added to make the cable round, and then processes such as sheath extrusion, cooling, and printing are carried out.
During the production process, each process is subject to strict quality inspection. For example, the measurement of insulation thickness and sheath thickness, and the testing of insulation resistance and voltage - withstanding performance, to ensure that the products meet the standards.
II. General Product Information
(I) Packaging
The packaging of these power cables aims to protect the cables and facilitate transportation and storage, and different packaging methods are adopted according to the models and lengths.
Long - length cables are usually packaged with wooden reels. The wooden reels are made of solid wood and can bear the weight of the cables. The cables are neatly wound on the wooden reels, and the outer layer is wrapped with a plastic film to prevent dust and moisture from entering. There are baffles on both sides of the wooden reels to prevent the cables from slipping, and information such as model, length, and weight is marked on them.
Short - length cables are packaged in cartons. The cartons are made of high - strength corrugated paper, and foam or soft materials are placed inside to fix the cables and prevent collision damage during transportation. The surface of the carton is printed with product information and marks such as "Handle with Care" and "Moisture - proof". The packaging materials meet environmental protection requirements and are recyclable.
(II) Transportation
For cable transportation, appropriate methods should be selected according to the quantity, distance, etc., and protective measures should be taken.
Trucks are used for short - distance transportation, which can be directly delivered to the destination, reducing handling links; for long - distance transportation of large quantities of cables, railway transportation is chosen, which has good stability and large transportation capacity. During transportation, the cables need to be placed flat, and those packaged with wooden reels should be fixed firmly to avoid collision and slipping.
When transporting in rainy days, the cables must be covered with rainproof cloth to prevent them from getting damp; in high - temperature weather, direct sunlight should be avoided, and transportation can be arranged in the morning and evening. Special tools such as forklifts are used for loading and unloading, and dragging is strictly prohibited to prevent damage to the cables and packaging.
