3M Scotch 130C Electrical Tape 1-1/2" x 30 ft 30 mil Black PK12

What this tape is and who uses it

3M Scotch 130C is a black, rubber-based, self-fusing electrical insulating tape supplied as a pack of twelve continuous rolls. Each roll measures one-and-a-half inches wide by thirty feet long with a thirty-mil thickness and a sixty-nine-kilovolt voltage rating. It is intended for professional electricians and maintenance crews who need reliable high-voltage insulation and moisture sealing on cable splices and terminations.

Check your application before ordering

Verify that your system voltage does not exceed the sixty-nine-kilovolt rating and that the operating temperature stays within the maximum of one hundred ninety-four degrees Fahrenheit. The tape has no minimum performance temperature rating, so confirm suitability for any cold-environment installations. Ensure the self-fusing rubber adhesive meets your splice-sealing requirements and that a twelve-roll pack matches your project quantity needs.

Behaviour under sustained load

The rubber adhesive maintains its self-fusing bond and insulating integrity continuously up to the rated maximum temperature of one hundred ninety-four degrees Fahrenheit. Because the tape is designed for continuous-roll application, it provides consistent dielectric strength and moisture resistance across long splice lengths during prolonged service. The thirty-mil thickness delivers stable mechanical protection and voltage withstand capability throughout extended duty cycles.
