Silicone-Rubber Insulation Covers for Power Lines & Substations
Jiadian Electric specializes in high-voltage insulation protective covers — for surge arresters, fuse cutouts, terminals, busbars and line connections — that insulate exposed live parts to prevent flashover and bird/animal-caused outages. We also supply surge arresters, fuse cutouts, switches and cable accessories. OEM / ODM welcome.
From surge protection to cable accessories — a complete range of MV/HV equipment for utilities, EPC contractors and panel builders, all built and tested in-house.
Yueqing is the heartland of China's electrical manufacturing industry — and JIADIAN ELECTRIC has been building MV/HV power distribution equipment here for over a decade. We design, mold, assemble and test every product under one roof.
Our range covers surge arresters, fuse cutouts, disconnecting switches, composite insulators, HV insulation covers, cold-shrink cable accessories and line fittings — supplied direct to utilities, EPC contractors and OEM customers in 30+ countries.
