Up to 45kV with optional fibre optics

Designed to house high voltage connections within a hazardous area, the 4TJB can terminate up to 45kV power or multi-use cables.

The 4TJB can accept up to three single-phase connections (one conductor per phase) in either a bottom entry or through box configuration. The rugged enclosure is based on Abtech's field-proven SX stainless steel junction box. It is DTS-01 deluge tested and fault rated to 40kA for one second.

The -125 variants offer a unique solution for the termination of offshore umbilical cables or onshore distribution systems. In this design, the power conductor compartment houses the HV cables. A separate control compartment is used for terminating fibre optic or control cables.

A thermostat-controlled heater can also be fitted to maintain a consistent internal temperature and prevent condensation build-up. The enclosure can be further configured with a sun canopy or painted to client-specific requirements.
