WDZN-YJV Fire Resistant Power Cable is a specialized low-voltage power cable developed for electrical systems that require improved fire safety performance and stable power supply capability. The cable structure shown in the product image consists of multiple functional layers, including copper conductor, XLPE insulation, fire-resistant barrier layer, filling material, and protective outer sheath.
The cable adopts a copper conductor to achieve efficient current transmission, while the XLPE insulation system provides reliable electrical separation and thermal performance. The additional fire-resistant layer helps maintain circuit operation for a certain period when exposed to fire conditions, making it suitable for power circuits where interruption may affect safety and operation.
With a rated voltage of 0.6/1kV, WDZN-YJV cable is commonly applied in buildings, public facilities, industrial systems, and emergency power distribution networks.
Product Features
1. High Conductivity Copper Conductor
The conductor is manufactured from high-quality copper material with stable electrical conductivity and low resistance.
The copper core design helps improve energy transmission efficiency and supports continuous operation in power distribution systems.
2. XLPE Insulation with Enhanced Thermal Performance
The insulation layer uses cross-linked polyethylene (XLPE), which offers stable performance under electrical and thermal stress.
Main characteristics include:
- High insulation resistance
- Good heat resistance
- Low dielectric loss
- Resistance to moisture and aging
This insulation structure helps maintain consistent electrical performance throughout the cable service period.
3. Fire Resistant Layer for Emergency Circuits
A dedicated fire-resistant layer is integrated into the cable structure to improve protection during fire exposure.
It helps maintain the electrical connection of important circuits, supporting continuous operation of essential equipment during emergency situations.
4. Low Smoke and Halogen-Free Option
The cable can be manufactured with LSZH materials according to project requirements.
During combustion, low smoke halogen-free materials help reduce toxic gas emission and improve safety in enclosed environments.
5. Durable Outer Protection
The external sheath provides mechanical and environmental protection for the internal cable layers.
It helps the cable withstand:
- Installation stress
- Surface abrasion
- Moisture influence
- Daily environmental exposure
6. Customized Structure Available
Different cable configurations can be produced according to application requirements, including:
- Conductor cross section
- Number of cores
- Sheath material
- Fire performance grade
- Cable marking
