Cable Terminal Protector (Cable Boot for RMU)

The Cable Terminal Protector (Cable Boot for RMU) is an insulating barrier system developed to provide effective phase-to-phase and phase-to-earth insulation for power cable terminations. It is specifically designed for use in confined spaces such as Ring Main Units (RMU), motor terminal boxes, and distribution transformers.

The system consists of an insulating boot, grommets, and plugs manufactured using injection-moulded EPDM rubber, offering excellent electrical insulation and tracking resistance. It effectively insulates right-angle cable connections, protects live components from airborne contamination, and helps maintain safe electrical clearances in compact switchgear assemblies.

FEATURES : The Cable Terminal Protector has a wide flexibility in voltage rating and conductor cross section (25 to 630 sq.mm.) The rubber boots which provide insulating barriers in the Cable Terminal protector enclose live parts. Due to the high track resistance and the insulating property of the barrier, the enclosed area remains comparatively small.

The live parts moreover are fully protected against air borne contamination which prevents formation of creepage currents. Due to the special flexibility of its design, the Cable Terminal Protector can be fitted to many different types of bushings with grooves, smooth, cylindrical and tapered. Modern switchgear where compactness is often achieved through the use of the insulating gas SF6, also require compact cable terminations. Cable Terminal Protector is extremely well suited for these switchgear.
