Description

The Gongniu Cable N2XSRY power cable is built with high-quality materials for optimal performance and a long service life.

Conductor: The cable features Class 2 circular compacted copper conductors, ensuring excellent electrical conductivity.
Insulation: Cross-Linked Polyethylene (XLPE) insulation provides outstanding electrical properties, high thermal resistance, and minimal dielectric loss. This contributes to efficient power delivery and enhanced durability.
Protective Layers: To manage electrical field stress effectively, the cable includes non-metallic, semi-conducting screens over the conductor and insulation. A copper tape metallic screen is also incorporated for grounding and fault current management.
Armour: Robust Steel Wire Armour (SWA) provides substantial mechanical protection, safeguarding the cable against physical impact and compression.
Outer Sheath: A tough Polyvinyl Chloride (PVC) outer sheath offers good resistance to various environmental factors, including grease, oils, and abrasion, ensuring the cable’s integrity in challenging conditions.

Gongniu Cable is committed to providing power solutions that you can rely on for safety and efficiency.
