We offer European separable connectors for 12kV, 24kV and 36kV.

They are manufactured with three-layer rubber injection molding vulcanization process. This method ensures tight bonding and significantly reduces partial discharge.

The shielded plug's inner and outer geometry is engineered to optimize the electric field. The uniform outer shield is grounded to below 5000 Ω, keeping the cable head at zero potential. This design improves safety for maintenance personnel.

The backbone of cold shrink products----Support Strip.

It securely maintains the pre-expanded form of cold shrink components before installation, enabling simple, fast and hassle-free field mounting. After removal, it allows the cold shrink material to contract uniformly and closely fit the cable body. Serving as a critical structural component, it ensures consistent sealing reliability and long-term operational stability for medium-voltage cable networks.
