Product Description
- Insulation material:
- Cross-linked polyethylene (XLPE) is used as the insulation material. This material has excellent electrical insulation performance and can effectively prevent current leakage, ensuring the safety and stability of power transmission.
- XLPE has good heat resistance. Its long-term allowable operating temperature is relatively high and can usually operate normally at around 90°C. In special cases such as short circuits, the temperature it can withstand in a short time is also relatively high, for example, it can reach about 250°C, and can adapt to different working environment temperature changes.
- Low smoke zero halogen characteristics:
- The cable material does not contain halogens (such as fluorine, chlorine, bromine, iodine, etc.). When burning, it will not release toxic and harmful halogen-containing gases. This is of great significance for ensuring the life safety of people in case of fire, reducing the harm of toxic gases to the human respiratory tract and lungs.
- The amount of smoke generated during combustion is extremely small, which greatly improves the visibility of the fire scene, facilitates personnel evacuation and fire rescue work, and reduces the difficulty of escape and rescue obstacles caused by smoke.
- Flame retardant performance:
- It has good flame retardant characteristics and can effectively prevent the spread of flames. The cable material is designed with a special formula and processing technology. When encountering a fire source, it can extinguish itself or slow down the burning speed, reducing the harm and loss of fire.
- It meets relevant flame retardant standards and requirements, such as those formulated by the International Electrotechnical Commission (IEC). After strict testing and certification, the reliability of its flame retardant performance is ensured.
- Fire resistance performance:
- In the event of a fire and in a high-temperature environment, the cable can maintain normal power transmission function for a certain period of time, providing power support for the emergency operation of key equipment and systems. For example, it plays an important role in the power supply of fire-fighting elevators, fire pumps and other fire-fighting equipment.
- It has good high-temperature resistance and can maintain the integrity and insulation performance of the cable structure under the direct action of high-temperature flames, ensuring the continuity of power transmission.
- Structural composition:
- Conductor: Generally, metal materials with good electrical conductivity such as copper or aluminum are used as conductors. The shape can be solid or stranded to meet different current transmission requirements and mechanical strength requirements.
- Sheath: The sheath material usually has good wear resistance, corrosion resistance and waterproof performance. It can protect the internal structure of the cable from being affected by the external environment and prolong the service life of the cable. For low smoke zero halogen flame retardant and fire resistant cables, the sheath material also needs to meet the requirements of low smoke and zero halogen.
- Filling layer: A filling layer may be set between the conductor and the insulation layer inside the cable. It is used to fix the position of the conductor, enhance the mechanical strength of the cable and buffer external pressure. The filling material is generally alkali-free glass fiber filling rope, etc.
- Applicable scenarios:
- Widely used in places with high fire safety requirements, such as high-rise buildings, shopping malls, theaters, hospitals, subways, airports, nuclear power plants, petrochemical and other large public buildings and industrial facilities.
- Applicable to places with dense personnel and difficult evacuation, as well as places with high environmental requirements and the need to avoid toxic gases and a large amount of smoke generated by cable combustion.

Our Advantages
Before making cables, the selection of copper materials is of utmost importance. The copper materials we choose are all 99.99% oxygen-free copper rods.
Before production, conduct a circular inspection of the equipment to ensure that the probability of problems occurring at the production end is 0%.
Professional production equipment and strict requirements for product quality are our lifelines.
Conduct self-inspection during production, spot check by batch, and conduct ex-factory inspection after leaving the factory. Conduct product production supervision in strict accordance with steps that far exceed the ISO 9001 quality control standard.
Ultra-large-scale inventory is also one of our advantages
Not only do we have cables and wires. We are a group company. Under the company, there is a power design institute, a power installation company, a production plant for power distribution boxes and cabinets, a production plant for cable trays and cable accessories, and a production plant for cable conduits. We can provide integrated services from design and research to products and then to construction. If you have any power-related issues, we welcome you to discuss with us. We will do our best to provide a solution. And these services are permanently free of charge!!!
FAQ
I. General questions
-
Q: What do the letters in WDZN-YJY cable stand for?
A: "WD" stands for low smoke halogen-free, "ZN" stands for flame retardant and fire resistant, "YJ" stands for cross-linked polyethylene insulation, and "Y" stands for polyethylene sheath.
-
Q: What are the applicable scenarios of WDZN-YJY cable?
A: It is applicable to places with high fire protection requirements, such as high-rise buildings, shopping malls, hospitals, subways, nuclear power plants, petrochemical and other densely populated or important industrial and civil buildings.
