Installation

Cotran Brand KC71 EPR High Voltage Insulation Tape should be applied in successive half-lapped, level-wound layers until desired build-up is reached.

Step 1 Perform normal cable preparation, and remove separator from tape;




Step 2 Apply tape half-lapped, stretching the tape 100%, which is enough to reduce its width to around 2/3 of its original width;


Step 3 Finish breaking the tape by holding it with your thumb and stick the end well.
