NA2XBY – YJLV22 (Al/XLPE/STA/PVC)

These power cables are used for electricity supply in low voltage installation systems. They are well adapted to underground use in industrial applications with an additional mechanical protection. These cables can be laying indoor, tunnel and underground. Able to bear external mechanical force, but unable to bear large pulling force.

Application

Our NA2XBY – YJLV62 cable is ideal for power supply in low-voltage systems. It performs reliably in industrial settings, especially for underground installations that require additional mechanical protection. You can install this versatile cable indoors, in tunnels, or directly buried underground. It is built to withstand external mechanical pressures, though it is not designed for installations with significant pulling tension.

Description

The NA2XBY – YJLV62 cable from Gongniu Cable features a robust, dual-layer protected construction for dependable performance.

Conductor: It has a high-quality aluminum conductor, providing cost-effective electrical transmission.

Insulation: The Cross-linked Polyethylene (XLPE) insulation provides superior electrical properties. This allows for a high power carrying capacity and ensures a long service life with minimal dielectric losses.

Protection: For mechanical strength, the cable incorporates strong Steel Tape Armour (STA). This armour is complemented by an inner PVC bedding and a tough outer PVC sheath, forming a comprehensive protective system against external stresses, moisture, and chemical influences. This dual-layer protection enhances the cable’s durability.

Outer Sheath: The outer PVC sheath offers good resistance to oils and abrasion, making the cable suitable for challenging industrial environments.

This careful construction ensures the cable delivers consistent power and safety.
