3M Scotch® Rubber Splicing Tape 23
The 3M Scotch® Rubber Splicing Tape 23 is a premium-grade, self-fusing electrical tape designed for high-voltage applications. Measuring 2 inches in width, 30 feet in length, and 0.03 inches (0.76 mm) in thickness, this tape offers exceptional performance for insulating and splicing cables up to 69 kV.
Key Features
- Self-Fusing Ethylene Propylene Rubber (EPR) Backing: Ensures a strong, moisture-resistant seal by bonding to itself without the need for external adhesives.
- Highly Conformable: Adapts easily to irregular shapes and surfaces, providing uniform insulation and protection.
- Temperature Resistance: Rated for continuous operation at temperatures up to 194°F (90°C), withstanding emergency overloads up to 266°F (130°C).
- Special Polyester Liner: Prevents the tape from sticking to itself during unwinding, facilitating easy and clean application.
- Electrical Properties: Offers a dielectric strength of 800 V/mil and insulation resistance exceeding 10⁶ megohms, ensuring reliable performance in demanding electrical environments.
- Compliance: Meets ASTM standards and is RoHS 2002/65/EC compliant, aligning with industry regulations and environmental standards.
Applications
Ideal for both low and high-voltage applications, the Scotch® Rubber Splicing Tape 23 is suitable for:
- Primary electrical insulation for splicing cables from 600V to 69 kV on all solid dielectric cables.
- Jacketing high-voltage splices and terminations.
- Moisture-sealing electrical connections.
- Bus bar insulation and end-sealing high-voltage cables.
Its non-vulcanizing and shelf-stable nature ensures long-term reliability, making it a trusted choice for electrical maintenance and insulation tasks.
