RS 35kV medium voltage power cable is designed for reliable and safe power transmission in high-load power grids, industrial facilities, infrastructure projects, and renewable energy stations. Engineered in full compliance with IEC 60502 and GB/T 12706 standards, our cable features high-purity copper or aluminum conductors, XLPE insulation with triple-layer semi-conductive screens, and optional steel tape or steel wire armoring to deliver excellent electrical performance, thermal stability, and mechanical protection.

We provide full customization of conductor cross-section, sheath material, armoring type and delivery length, backed by our professional manufacturing capability and competitive factory price.

35kV Cable – Key Specifications & Construction

– Conductor:High-purity annealed copper or aluminum conductor, available in various cross-sections (50mm² to 800mm²).
– Insulation:XLPE (Cross-linked Polyethylene) or HEPR (Hard Ethylene Propylene Rubber) insulation, offering excellent thermal stability, high dielectric strength, and long-term aging resistance for 35kV high-voltage systems.
– Screen/Sheath:Triple-layer semi-conductive and metallic copper screen to precisely control electric fields and eliminate partial discharges; outer sheath (PVC, PE, or halogen-free LSZH compound) provides robust protection against oils, chemicals, UV radiation, and mechanical damage.
– Armoring:Optional galvanized steel wire armor (SWA) or steel tape armor (STA) for enhanced mechanical protection against crushing, impact, rodent damage, and tensile stress in heavy-duty installation scenarios.
– Voltage Rating:35kV (26/35kV, 21/35kV， 18/30kV(36kV))
– Standards Compliance:IEC 60502-2, IEC 60228, IEC/EN 60332-1-2, GB/T 12706, GB/T 11017
