N2XSY (YJV72) 18-30(36)kV (Cu/XLPE/CWS/PVC/AWA/PVC)

Application

Our N2XSRY – YJSV72 cable is specifically designed for medium voltage power distribution. It is a top choice for a wide range of critical installations. You can reliably lay it indoors, in tunnels, or in cable trenches. It also performs well when buried directly underground or installed in shafts. This cable is built to withstand significant mechanical forces and tensile stress. You will find it commonly used in key power infrastructure. This includes transformer stations, electric power plants, and various industrial facilities. Gongniu Cable ensures your power delivery is secure and stable in these demanding environments.

Description

The N2XSRY – YJSV72 power cable features a carefully engineered structure for superior performance:

• Conductor: It uses a high-quality copper conductor. This conductor is circular and compacted for excellent electrical conductivity
• Conductor Screen: A non-metallic, semi-conducting compound surrounds the conductor. This layer helps to smooth the electric field, ensuring stable operation
• Insulation: The cable features cross-linked polyethylene (XLPE) insulation. This material offers high dielectric strength and excellent resistance to heat, making the cable very reliable
• Insulation Screen: Another layer of non-metallic, semi-conducting compound covers the insulation. This further optimizes the electric field distribution
• Metallic Screen: A copper wire screen is incorporated. This metallic layer provides critical protection against electromagnetic interference and helps with fault current handling
• Inner Sheath: A polyvinyl chloride (PVC) inner sheath protects the core components. This provides an additional layer of insulation and mechanical stability
• Armour: Crucially, this cable includes a steel wire armor (SWA). This robust layer provides outstanding mechanical protection. It safeguards the cable from external impact and crushing forces, especially important for direct burial applications
• Outer Sheath: The cable is finished with a tough polyvinyl chloride (PVC) outer sheath. This sheath offers excellent resistance to abrasion, moisture, and chemical exposure, prolonging the cable’s lifespan

Overall, this design provides good electrical and mechanical properties, ensuring minimal dielectric loss and high insulation resistance for long-term reliability.
