Product Features

1. High Conductivity Copper Core

The cable uses high-quality copper conductors with excellent electrical conductivity and low resistance characteristics.

The conductor structure ensures efficient power transmission while reducing energy loss during long-term operation.

2. XLPE Insulation for Stable Electrical Performance

The insulation layer adopts cross-linked polyethylene (XLPE), which provides:

• High insulation strength
• Good thermal stability
• Low dielectric loss
• Resistance to aging and moisture

The material helps maintain reliable performance under continuous electrical loading.

3. Fire Resistant Construction

The cable incorporates a fire-resistant layer between the conductor insulation system and outer protection structure.

This design improves the cable’s ability to maintain electrical continuity under fire conditions, making it suitable for safety-critical applications.

4. Low Smoke and Halogen-Free Safety Design

The cable can be manufactured with low smoke zero halogen materials, reducing the release of corrosive gases and harmful smoke during combustion.

This feature is especially important in enclosed public spaces.

5. Strong Mechanical Protection

The outer sheath provides protection against:

• Mechanical impact
• Abrasion
• Moisture penetration
• Environmental exposure

It improves cable durability during installation and operation.

6. Suitable for Fixed Power Distribution Systems

WDZN-YJV is mainly designed for fixed installation and is commonly used in power supply networks requiring higher safety standards.

According to the cable structure shown in the product image:

1. Copper Conductor
