Splicing tape for high-voltage insulation
This splicing tape is built for insulating electrical connections up to 69 kV. It uses ethylene propylene rubber backing with a self-fusing rubber adhesive that bonds to itself without sticky residue. The tape performs reliably from 32 to 194 degrees Fahrenheit. It is suited for electricians and maintenance crews working on high-voltage cables and splices.
30 mil thickness and self-fusing adhesive
The critical specification is the 30 mil thickness combined with a self-fusing adhesive format. This thickness provides the dielectric strength needed for 69 kV ratings, while the self-fusing property creates a void-free, moisture-resistant insulation layer that does not rely on conventional adhesion. Selecting a thinner tape or a non-fusing type would not meet the same insulation requirements.
Continuous roll format for custom lengths
The tape comes as a continuous roll measuring 2 inches wide by 10 yards long, allowing installers to cut exact lengths for each splice. This reduces waste compared to pre-cut strips and accommodates irregular cable diameters. The black finish aids UV resistance in outdoor environments. No additional tools or activators are required for application.

Questions about this item
How much continuous roll length does the 30 ft specification provide for a splice?
The tape comes as a continuous roll of 30 feet, giving you up to 10 yards of self-fusing rubber tape to wrap and insulate a splice in one piece.
What voltage level does the 69 kV rating allow the tape to handle in service?
The tape carries a 69 kV voltage rating, meaning it is designed to insulate splices on circuits operating at up to 69 kilovolts when applied correctly.
What minimum and maximum temperatures can the installed tape withstand on the job?
Once applied, the tape remains functional from a minimum of 32 °F up to a maximum of 194 °F, covering typical indoor and outdoor electrical environments.
