Product Overview
The CCSJ Cold Shrink Straight Joint is a high-performance solution for straight jointing of medium-voltage cables up to 42kV. Manufactured from premium silicone rubber and supplied in a pre-expanded design, it enables fast, tool-independent installation while ensuring long-term electrical and mechanical reliability.
Featuring integrated stress control, excellent resistance to partial discharge, thermal short-circuit, and electrical heat cycling, the CCSJ is designed for demanding indoor and outdoor network conditions. With just three sizes covering conductor ranges from 185 mm² to 1000 mm² and compatibility with multiple connector types, it offers a compact, versatile, and dependable jointing solution for modern MV power systems.
Cold shrink technology eliminates the need for heat or special tools, reducing installation time and site risk.
Factory-controlled expansion ensures uniform radial pressure and reliable electrical contact throughout service life.
Built-in stress control system minimizes electrical stress enhancing insulation integrity and joint longevity.
Only three joint sizes cover conductor cross-sections from 185 mm² to 1000 mm² simplifying selection and inventory.
Proven resistance to partial discharge, impulse voltage and AC/DC withstand voltages under severe conditions.
Excellent performance in wet, humid, and harsh environments, suitable for both indoor and outdoor installations.
Durable silicone rubber construction ensures long-term, trouble-free service with minimal maintenance.
