Dielectric High Silica Tubular Braided Rope
Low-Moisture Tubular Braided High Silica Rope for Electrical & High-Temperature Insulation
Dielectric High Silica Tubular Braided Rope is manufactured from high-purity silica fibers (SiO₂ ≥96–98%) using a hollow tubular braided construction that delivers excellent dielectric strength, very low moisture absorption, and outstanding thermal stability.
The tubular braided design provides higher compressibility, better recovery, and uniform sealing pressure, making this rope ideal for dynamic joints, uneven surfaces, and applications requiring reliable electrical insulation under thermal cycling.
Compared to solid braided or twisted ropes, tubular braided high silica rope offers enhanced resilience, improved sealing efficiency, and reduced installation stress, while maintaining stable electrical properties in humid and high-temperature environments.
