Medium Voltage EPDM Separable Connectors

The easy to install range of plug-in separable connectors from 3M are moulded using high quality EPDM and meet the requirements of EN 50180 and EN 50181.

Designed for indoor use and suitable for a wide range of applications the straight, elbow and T-Plug connectors are sold in packs of 3 and come with silicone stress control elements, earthing set, mechanical cable lug for main conductor, mechanical cable lug for wire screen, all assembly materials and assembly instructions.

All medium voltage connector kits are fully type tested to Cenelec HD 629.1 (DIN VDE 0278) and are available for voltage classes 6.6/11(12)kV, 20/22(24)kV, and 19/33(36)kV.

The screened separable connectors are suitable for single core, copper wire screened, un-armoured cables, in a wide range of sizes, for outer cone bushings.

Individual range data sheets are available, with full details of each kit – please contact Thorne & Derrick for more information.

Cable Box Terminations & Connectors – Inner Cone & Outer Cone

Cold shrink is typically used for the dry termination of medium/high voltage 11kV-33kV cables into MV-HV air insulated cable boxes.

T&D also distribute MV-HV Connectors for terminating cable into metal-enclosed SF6 insulated medium voltage switchgears (GIS) and liquid immersed transformers.
