This lead wire consists of stranded nickel plated copper conductor insulated with Teflon, glass, glass, Teflon (TGGT), or 27% nickel clad conductor insulated with glass reinforced mica (MG) for optimum dielectric strength under extreme temperatures. Both are U.L. and C.S.A. approved.
Used to protect lead wire against abrasion or physical damage in hazardous environments and provides protection from excessive flexing.
