3M 130C-3/4'' High Voltage Linerless Rubber Tape

Product Description

The 3M 130C-3/4'' is a linerless, self-fusing rubber electrical tape designed for high voltage splicing and insulation applications. Measuring 0.75 inches wide by 30 feet long, this all-voltage tape conforms tightly to irregular surfaces without a release liner, allowing direct application and self-amalgamation under tension. It is a go-to product for electricians working on cable splices, terminations, and insulation builds in demanding environments. The rubber construction provides excellent dielectric strength and moisture resistance, making it suitable for both indoor and outdoor electrical work.

This tape is used in residential, commercial, and industrial electrical installations where high voltage insulation is required. Typical applications include splicing and insulating medium-voltage cables, building up insulation on conductors, and sealing connections against moisture ingress. It is installed by licensed electricians on service entrance conductors, cable joints, and transformer leads where reliable dielectric performance is critical.

Key Features

• Linerless construction allows direct, liner-free application without peeling a release sheet
• Self-fusing rubber compound bonds to itself under tension for a solid, void-free insulation layer
• 0.75 inch width and 30 ft length suitable for a wide range of splice and termination builds
• All-voltage rated for use across a broad range of electrical system voltages
• Black color provides UV identification standard in electrical insulation applications
• Rubber material delivers strong moisture resistance and dielectric performance

Compatibility

Designed as an OEM-style linerless rubber tape for use in high voltage electrical splicing, insulation building, and cable termination applications compatible with rubber-to-rubber bonding surfaces.

Installation Notes

This tape is installed by licensed electricians. De-energize and lock out the circuit before beginning any splice or termination work in accordance with NFPA 70 (NEC) requirements. Apply the tape under consistent tension, stretching slightly as you wrap to activate self-fusion and eliminate voids. Do not use this tape as a primary mechanical protection layer without an additional jacketing or armor layer where required by code.
