KC80 Waterseal Mastic Tape CONTRA No.KC80 Waterproof and Insulation Tape
Protecting power cables and optical telecommunication lines from moisture intrusion and insulation breakdown can be challenging when dealing with irregular splices and junction boxes. The KC80 Waterseal Mastic Tape by CONTRA provides a reliable sealing and insulation solution designed for professional electrical applications.
Applications and Uses
This single-sided pressure-sensitive tape is built for insulation, filling, and moisture sealing across multiple scenarios. Key applications include:
- Splices of all types of power cables and optical telecommunication cables for primary insulation up to 1000 volts
- Insulating and moisture sealing on bus bars
- Moisture sealing high or low voltage junction boxes and irregular splices
Application Instructions
For optimal performance, follow these application steps:
- Wipe off any dust on the splice area before wrapping.
- Remove the liner and stretch the tape to 1 to 2 times its original length. Apply the tape 50% lapped with the mastic side toward the area to be wrapped (do not overstretch to 4 times length).
- Extend wrapping 30mm to 50mm up onto the cable jacket on both sides of the splice area.
- Overwrap with COTRAN PVC insulation tape: apply 3 layers in a 50% overlap with no tension.
