Product Overview
The COMPAQ Elbow Terminal Protector is designed to improve insulation reliability in compact cable entry boxes and RMUs where reduced clearances can increase the risk of air flashover. By providing an additional dielectric layer around live terminations, it supports safer operation in confined medium-voltage installations.
Manufactured from high-performance EPDM or Silicone rubber, the moulded protector offers strong dielectric strength, resistance to UV and tracking, and stable mechanical performance. Suitable for installation on epoxy bushings, the one-piece design enables quick installation and consistent insulation performance under service conditions.
One-piece, slip-on design allows rapid deployment on-site without tools or adhesives.
Supports cable cross-sections from 25 sq.mm to 300 sq.mm.
Especially effective in humid, dusty, or rodent-prone environments.
Allows safe voltage detection without removing the protector.
Long service life with the option to remove and reinstall.
Continuous operation up to 90°C; withstands 130°C for 4 hours in overload conditions.
Specifically for applications with C-type bushings and limited clearance.
