High Voltage Rubber Tape

High voltage rubber tape is 69KV splicing tape ,customer also like to call it self amalgamating tape, it is used for 69kV and below cable wrapped low-stress intermediate joint and terminal sheath recovery,Electrical insulation and moisture-proof sealing of indoor and outdoor high-voltage cables, Moisture-proof and sealing of electrical connections of all solid dielectric cable insulation layers, Physical and electrical properties can not be affected by the degree of stretching,Special polyester release paper, will not stick to the tape when the tape is unwound, Professional supporting materials for cold and heat shrinkable cable accessories

Brief introduction:

Model: J-40 

Material:Ethylene-propylene rubber base tape, self-fusing tape

Features of High Voltage Rubber Splicing Tape:

Ethylene-propylene rubber tape base, no special tools required, self-melting and self-adhesive repair tape

Easy to remove the release film, it will not stick to the tape when the tape is unwound

Good conformability to irregular surfaces

Can be used for butt connection and termination of cables, emergency overload temperature 130℃

Good physical and electrical properties are not affected by tape stretching

Good compatibility with various cables and wires

Steps for usage

1. Tear off the isolation film

2. Stretch 200%

3. Winding under tension

4. The half-tower type is tied to the position to be wrapped; after wrapping, squeeze the tape on the covered area by hand to make the layers stick tightly without air gap for sufficient bonding. Finally, wrap two layers of PVC tape on the outside of the tape. To provide mechanical protection
