Product Detail

Product Description

Cotran Brand KC72 electrical semi-conducting tape is a Highly conformable, self-fusing, semi-conducting ethylene

propylene rubber(EPR) based, high voltage splicing tape. KC72 is used for repairing of XLPE cable terminations

and joints or shielding for other devices up to 110kV.

Applications

◆ Uniform electric field in high electric field, to minimize electrical stresses in

◆ Continue semi-conducting strand shielding found in solid dielectric cables above 5kV.

◆ Provide shielding layer for solid dielectric insulated cable.

◆ Repair the semi-conducting layer beneath metallic shield of similar cables in case of damage

◆ Make conductive portion of stress cone of power cable termination on solid dielectric insulated cables.

Installation

Cotran Brand KC72 electrical semi-conducting tape is usually wrapped in half-lapped layers. With excellent elongation, stretched overwrapping the connectors, terminals, and metallic shield of power cable.

Step 1 Wipe off the dusts on the power cable area before wrapping.

Step 2 Remove the liner and stretch the tape to 1 to 2 times of its original length, apply the tape in 50%-lapped toward area to the wrapped. Stretching the tape to 4 times of its original length is not recommended.
