Product Overview

The COMPAQ CSTI Series is a screened separable T-front connector—also known as a touch-proof termination—designed for safe, compact, and reliable connection of single-core or three-core polymeric cables up to 42kV. Engineered for seamless integration with gas-insulated switchgear, transformers, and motors, CSTI connectors combine space-saving design, robust insulation technology, and user-friendly installation.

Precision-moulded from high-quality EPDM and Silicone insulation compounds, each connector is rigorously tested to ensure electrical reliability, mechanical strength, and long-term resistance to environmental stress.

How Are We The Best
