Dielectric High Silica Tubular Braided Sleeve
Low-Moisture Tubular Braided High Silica Sleeve for Electrical & Extreme-Temperature Insulation
Dielectric High Silica Tubular Braided Sleeve is manufactured from high-purity silica fibers (SiO₂ ≥96–98%) using a hollow tubular braided construction that provides excellent dielectric strength, very low moisture absorption, and superior thermal resistance.
The tubular braided structure allows the sleeve to expand and contract easily, enabling quick installation over cables, hoses, and components while ensuring uniform electrical insulation and thermal protection.
This makes it ideal for high-voltage, RF-transparent, and high-temperature environments where reliability is critical.
