Features

Premium Material: Made from top-quality liquid silicone rubber, featuring excellent insulation, aging resistance, 

pollution resistance, low-temperature endurance, and superior hydrophobicity.

 

Advanced Manufacturing: Produced with precision equipment, ensuring rubber components are free from 

bubbles, burns, and contaminants. Strong bonding between insulation and semi-conductive layers eliminates cracking or delamination.

 

Easy Installation: Utilizes the “elastic memory”of silicone rubber. Rubber parts are pre-expanded over

removable plastic cores; once removed, the component shrinks tightly onto the cable, requiring no heat or special tools.

 

High Adaptability: Suitable for areas with high altitude, extreme cold, pollution, or fire and explosion risks—

ideal for industries like petrochemical, mining, and heavy industrial zones.
