Medium Voltage

Hybrid Technique
Straight-through Joint Type CHMPPR3 and CHMPP(H)3
for belted cables up to 17.5 kV • for H-cables from 24 up to 36 kV
Application
Straight-through joints
– Type CHMPPR3 applicable for belted and Hoechstaedter cable from 6 up to 17.5 kV
– Type CHMPP(H)3 applicable for Hoechstaedter cable from 24 up to 36 kV
For paper cables with small conductors an adapter kit is available.
Features
• Quick, easy and safe installation due to the combination of slip-on and heat-shrink components
• Reliable stress control for all operating conditions due to flexible silicone stress control elements
• Wide cross section range suitable for all types of connectors
• Unlimited shelf life and immediate operation after installation
Design
A kit of a straight-through joint consists of the following main components:
• Silicone stress control elements
• Blue filling tape with stress control and oil resisting features
• Oil-resisiting heat-shrink tube
• Conductive heat-shrink tubes and spreader cap
• Insulating thick-wall heat-shrink tubes
• Copper braid sleeve
• Thick-wall heat-shrink tubes with hot melting adhesive as an outer protection
Delivery
One kit for three phases without connector.
Required connectors can be ordered separately.
