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
- Joints are suitable for all types of cables having different screening and armour designs
- Immediate energization after completion of joints
- Conforms to various national and international standards like CENELEC HD.629.1.S2:2006, IEC 60502-4, IEEE 48 and IS 13573-2
- Next Gen Joints – Triple layer co-extruded single heat-shrinkable tubing incorporating precisely engineered impedance stress control. MXSU joints are supplied with mechanical phase and screen connectors for a wide range of conductor sizes with no limitat
