WRSHG
Heat Shrink Protective Tube
Manufactured from cross linked polyolefin. Providing outer sealing protection for power cable joints up to 42kV. Used in 1kV cable joints and terminations to provide electrical insulation (Φ50 and below). Outstanding abrasion and chemical resistance. Inner coated with adhesive at both ends. Tubes inner coated with adhesive at full length are available upon customer request. Shrink temperature: start at 90℃, and fully recovered at 130℃Color: black, red, yellow, blue, green(Φ50 and below); black only(above Φ50). Other colors are available upon customer request.
