35kV Cold Shrink Termination

35kV Cold Shrink Termination

Product Description

The 35kV Cold Shrink Termination represents a significant leap forward in medium-voltage cable termination technology. Engineered for unparalleled efficiency and reliability, this solution is designed to meet the rigorous demands of modern power distribution networks. Its core innovation lies in a pre-expanded, high-grade silicone rubber core that is securely held in its expanded state by a simple, removable plastic support ring. The installation process is remarkably straightforward: upon positioning the termination, the removal of the support ring triggers a controlled, radial shrinkage. This action creates an immediate, permanent, and waterproof seal around the cable without the need for heat, flames, or any specialized tools.

This heat-free, cold-shrink methodology fundamentally eliminates the performance variability and potential cable damage associated with traditional heat-shrink techniques, such as uneven shrinkage, cold spots, or operator error. The result is a flawlessly installed termination, every time, ensuring maximum electrical integrity and operational safety right from the start. This makes it an exceptionally versatile solution for a vast array of applications, including utility power grids, industrial plant networks, commercial complexes, and critical connections within wind and solar renewable energy facilities.

Beyond its installation advantages, the termination is engineered for long-term resilience. It features an integral, geometrically optimized stress control system that smoothly grades the electrical field at the cable end. This advanced design effectively minimizes electrical stress concentration, suppresses partial discharge, and significantly enhances the service life of the cable connection. The high-performance silicone rubber material offers exceptional resistance to environmental challenges, including UV radiation, moisture, chemical pollution, and a wide operating temperature range from -50°C to +50°C, ensuring stable performance in the harshest indoor and outdoor conditions.

Designed for broad compatibility, this termination accommodates a wide spectrum of cable types and conductor sizes. It serves as a robust, maintenance-free interface for connections to transformers, switchgear, and Ring Main Units (RMUs). By drastically reducing installation time, eliminating hot-work permits, and removing the risk of installation-related failures, the 35kV Cold Shrink Termination delivers not only superior technical performance but also significant life-cycle cost savings, establishing itself as the intelligent choice for a reliable and future-proof power infrastructure.
