Application areas:
It is mainly used for insulation protection of the terminals or intermediate joints of medium and low voltage power cables, and insulation protection of various busbars.
Product Description
Semi-rigid medium-wall tubing is extruded from semi-rigid polyolefins and possesses excellent insulation properties and impact and abrasion resistance. It is primarily used for insulation protection of terminals or intermediate joints in medium and low-voltage power cables, as well as insulation protection of various busbars. Its high shrinkage ratio allows the product to be used for sealing and protecting joints of different sizes and shapes.
Heat shrink ratio: 3:1
Initial shrinkage temperature: ≥ +70 ℃
Complete shrinkage temperature: ≥ +125 ℃
Operating temperature: -45 ℃ ~ +110 ℃
UV resistant and wear-resistant
Environmental Standards: RoHS
Standard color: Black (other colors can be customized)
