Product Overview
COMPAQ CSTI is a screened separable T-Front connector, designed for the safe and efficient connection of single-core and three-core polymeric cables up to 42kV. Commonly known as a touch-proof termination, it provides a compact and reliable solution for integration with switchgear, transformers, and motors, making it ideal for modern power distribution networks.
Engineered with advanced EPDM and silicone insulation technology, CSTI connectors provide excellent electrical reliability, mechanical strength, and long-term resistance to environmental stress. Each kit includes precision-designed multi-range mechanical lugs, ensuring consistent performance and simplified installation under a wide range of site conditions.
With its space saving design, robust sealing system, and user friendly assembly, the CSTI Series delivers dependable connections that safeguard network integrity while reducing downtime and maintenance needs.
Designed specifically for EN 50180 / EN 50181 Type C bushings, ensuring perfect compatibility with gas-insulated systems.
Designed to fit easily into modern, space-restricted switchgear and substation environments.
Fully screened body prevents accidental contact with live parts, improving operator safety.
Range-taking design supports a wide variety of cable types, sizes, and applications, reducing the need for multiple connector variants.
Compatible with cable cross-sections from 35 mm² to 1000 mm², offering flexibility across diverse installations.
Manufactured under ISO 9001-certified processes, reflecting COMPAQ’s 25+ years of excellence.
