  • NKS POWER

Separable connector product introduction:


NKS POWER separable connectors (rear connectors, couplings) are suitable for terminating incoming and outgoing lines of RMUs, switch cabinets, and cable branch boxes (XLPE, EPR, etc.). There is no minimum phase gap requirement and cannot be used alone.

Expansion connection with the separable front connector (T-type connector) provides expansion branches, and the installation method can be vertical, horizontal or at any angle.

Product execution standards: IEC60502.4, GB/T12706.4

The product matches the C-type bushing in EN50180&50181.


Separable connector product features:


Molded from safe and environmentally friendly silicone rubber

Has excellent insulation properties, corona resistance and tracking resistance

Reasonable structural design, three-layer post-injection peroxide cross-linking process to reduce partial discharge

Built-in stress control, uniform electric field distribution

Suitable for copper and aluminum cables

Quick assembly and simple installation
