1 like563 views
The document describes 3M's IMCSN Medium Wall Heat Shrink Tubing. It is designed to provide reliable electrical connections and protect them mechanically and environmentally. The tubing is fabricated from cross-linked polyolefin, is highly split resistant, and shrinks rapidly during installation. It offers benefits like fast installation, puncture resistance, complete environmental protection, and adhesion to various substrates. The tubing can be used for insulating electrical splices or providing physical protection and moisture sealing of high voltage connections and lugs. Selection involves choosing the largest tubing that fits tightly around the cable when shrunk.

3M Heat Shrink Tubing Medium Wall IMCSN
- 1. IMCSN Medium Wall Heat Shrink Tubing Product Description 3M™ IMCSN Medium Wall Heat Shrink Tubing is designed to provide reliable performance for electrical splices, connections, and terminations, as well as mechanical and environmental protection. IMCSN is fabricated from cross-linked polyolefin. The tubing is highly split resistant, and fast-shrinking to provide rapid installation. The tubing comes standard with a factory-applied adhesive/sealant. Product Features • Fast and easy installation • Resists puncture and abrasion damage • Complete environmental protection • Versatile, a minimum number of sizes cover the entire range of applications • Shrink ratio 3:1 • Resists acids and alkalies • Bonds to a wide variety of substrates • Reliable and proven • UV resistant Applications • Primary electrical insulation for solid dielectric wire and cable rated to 1000 volts • For indoor, outdoor or overhead use • Direct buried or submersible • Insulating secondary splices • Physical protection and moisture sealing of high voltage air insulated connectors and lugs, such as lug connections to bus bars • Relocation of service • Dig-in repairs Product Selection Selecting 3M IMCSN tubing is easy and straightforward. The largest tubing that provides a tight fit when fully recovered will produce the maximum wall thickness. Final wall thickness is proportional to the degree of tubing recovery.
