Installation

Cotran Brand KC78 eletrical insulation filler tape should be applied in successive half-lapped, level-wound layers until desired build-up is reached.

Step 1 Wipe off the dusts on the splice 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 with mastic side toward area to the wrapped. Stretching the tape to 4 times of its original length is not recommended.

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

Step 4 AfterKC78 electrical insulation filler tape is applied, overwrapping COTRAN PVC insulation tape is recommended, apply 3 layers of COTRAN PVC insulation tape in a 50% overlapping with no tension. Make sure not to overstretch the PVC tape during installation.
