10KV Silicone Rubber Cold Shrink Termination

 

Features:

Ÿ           Adopt imported liquid silicone rubber from Germany, with reliable insulation and high-recovery elasticity

Ÿ           Unique Hi-K stress control material, self-recovery and pre-stretched technology Cold shrink delivery system allows quick easy installation without flame, special tools or extensive training.

Ÿ           The product is pre-stretched on a removable core. Removal of the core after positioning the termination allows the product to shrink into position, providing a tight seal.

Ÿ           Once installed, cold shrink termination creates a dynamic, compressive environmental seal and electrical interface without sealants or adhesives.

Ÿ           Wanma Cold Shrink Termination will retain its interface pressure for more than 30 years, based on accelerated life testing.

Ÿ           Meets or exceeds IEC60502.4, GB/T12706.4, JB/T8144

Ÿ           Can be used on a wide range of cable insulations in a variety of applications

Ÿ           Indoor and outdoor are available
