Cable Accessories LV to EHV

Medium Voltage Heat Shrink Joints-Conventional and next generation. Raychem developed highly specialized polymers for heat shrink joints suitable for plastic and paper cables upto 36 kV. For transition joints, a special oil barrier tubing is used to transform draining oil (MI) and non-draining oil (MIND) paper insulated cable into quasi-polymeric insulated cable with a radial field.

The conventional design developed in 1980 was based on multiple layer tubing concept providing insulation and stress functions. The latest developed heat shrink joint is a single tubing (triple layer co-extruded) of adequate thickness which provides insulation for a particular voltage range.

• Conventional Joints – Multi-layered heat-shrinkable tubing incorporating precisely engineered impedance stress control. EPKJ universal joints are suitable for a wide range of connectors and cable sizes with no limitations on shelf life

Medium Voltage screened separable connectors for switchgears. Raychem developed screened separable connectors for switchgears which are compact and space saving, having high degree of reliability and safety. These terminations are designed, developed, and tested upto 36 kV for almost all sizes of cables. Switchgear terminations are either OUTER CONE type (suitable for bushings as per EN 50181 for Type A (250 Amps), B (400 Amps), C (630/800 & 1250 Amps)) or INNER CONE type Size 2 (800 Amps) and Size 3 (1250 Amps). Screened separable connectors conform to IEEE bushings and terminations to CENELEC HD 629.1 and IS 13573-2 standards.
