Stress Controlled Heat Shrink Tube

Code: N/A

Axis Stress Controlled Heat Shrink Tubes are designed for medium-voltage (MV) applications to provide superior electrical insulation and stress control at cable terminations and joints. Made from cross-linked polyolefin materials, these tubes offer excellent dielectric properties, mechanical strength, and environmental resistance. They effectively distribute electrical stress, reducing the risk of insulation failure. When heated, the tubes shrink uniformly, forming a tight, protective layer that adapts to various cable sizes. These tubes ensure the reliability, safety, and efficiency of electrical systems in MV applications.
