TVP 4.0 kV

Fiberglass sleeve

Tube structure: fiberglass braided support covered with polyurethane resin.

Description: the union between the braided fiberglass and polyurethane resin through a polymerization process at high temperatures, ensures at the sleeve type TVP 4.0 KV good dielectric properties, thermal protection and high mechanical strength.
