What is Varnished Fiberglass Sleeving?

Varnished Fiberglass Sleeving is a flexible tubular insulator that comprises a braided non-alkali fiberglass yarn tube that has been coated with electrical insulating varnish. The varnish coating on the braided fiberglass tube increases the dielectric strength and moisture resistance properties, while the fiberglass tube provides great flexibility and heat resistance.

Varnished fiberglass sleeving is thus an economical way to insulate and protect individual wires and cables in electrical and electromechanical devices.
