TVA 3.0 Kv

Fiberglass sleeve
Tube structure: fiberglass braided support covered with acrylic resin.
Description: the union between the braided fiberglass and acrylic resin through a thermal process, ensures at the sleeve type TVA 3.0 KV good dielectric properties, thermal protection and high mechanical strength.

Main features
