YJLSV 1×800mm² Watertight Aluminium Medium Voltage Power Cable – XLPE Insulated, 26/35kV
Compliant with GB9330, IEC 60502-2 | CCC, ISO 9001, RoHS
Product Overview
The YJLSV is a watertight single-core aluminium power cable designed for 26/35kV medium voltage systems. It features an aluminium Class 2 conductor, XLPE insulation, longitudinal water-blocking with HDPE tape/swelling powder, and a corrosion/UV-resistant PVC jacket. The cable is suitable for underground power transmission, substations, industrial parks, renewable energy projects, and flood-prone or high-humidity installations.
Applications
-
Underground power transmission (26/35kV systems)
-
Substations, industrial parks, and renewable energy projects
-
Flood-prone or high-humidity installations
Features & Benefits
-
Waterproof Design: HDPE/swelling layers prevent moisture ingress.
-
Lightweight: Aluminium conductor reduces weight vs. copper.
