N2XSERY (YJV32) 18-30(36)kV (CU/XLPE/CTS/SWA/PVC)

Medium voltage cables for distribution networks. They are suitable for laying Indoor, tunnel, cable trench, shaft or buried laying, The cable can withstand mechanical external forces and a certain tensile force, it widely used in transformer stations, electric power plants and industrial plants.

Applications

The Gongniu Cable N2XSERY is a medium voltage cable designed for power distribution networks. You can install this versatile cable in a variety of settings. These include indoor locations, tunnels, cable trenches, and shafts. It is also suitable for direct burial in the ground. This cable is built to withstand external mechanical forces and offers good tensile strength. It is commonly used in transformer stations, electric power plants, and various industrial plants.

Description

Our N2XSERY cable features a robust construction to ensure lasting and reliable service.

Conductor: The cable uses Class 2 circular compacted copper conductors. This provides excellent electrical conductivity.
Insulation: It is insulated with Cross-Linked Polyethylene (XLPE). XLPE offers superior electrical properties, helps minimize dielectric loss, and ensures high insulation resistance.
Screening: The cable includes non-metallic, semi-conducting screens for both the conductor and the insulation. A copper tape screen (CTS) provides effective metallic screening.
Protection: We use a non-hygroscopic filler material. The inner sheath is made from Polyvinyl Chloride (PVC). For strong mechanical protection, the cable is equipped with Steel Wire Armour (SWA).
Outer Sheath: A tough Polyvinyl Chloride (PVC) outer sheath protects the cable. This layer offers good resistance to grease, oil, and abrasion.

Overall, the N2XSERY cable from ZD Cable delivers good electrical performance and mechanical strength.

Specifications

Gongniu Cable’s N2XSERY power cables are manufactured in compliance with key international standards. This ensures their quality and suitability for relevant applications.

The main standards include:

IEC 60228: This standard specifies requirements for the conductors of insulated cables.
IEC 60502-2: This standard applies to power cables with extruded insulation and their accessories for rated voltages from 1 kV (Um=1.2kV) up to 30kV (Um=36kV). Specifically, Part 2 covers cables for rated voltages of 6kV (Um=7.2kV) and 30kV (Um=36kV).
