The 07-96..-.. type series II 1G line bushing serves as a gas diffusion-proof isolation element for zone 0 (1G/2G) while simultaneously providing an electric connection for leads:- between flameproof enclosures- between flameproof enclosures and enclosures with another approved type of protection Category II 2 G- flameproof enclosures and protected installations Category II 3 G or-in the safe areaThe core piece of this gas diffusion-proof leadthrough is a metal plate in which the stud-type bushings are insulated with glass. The electrical connection on both sides of the lead-through can be set forth with metal duct bolts, cable wires or hose lines as required. This connecting area is, or can additionally be, cast with a poured resin. The connector studs, connecting wires or the hose line of the line bushing II 1G must be connected in enclosures which conform to a type of protection standardised according to DIN EN 60079-0. The lead-through is compliant with the pertinent DIN EN 60079-0, DIN EN 60079-1 and DIN EN 60079-7 and DIN EN 60079-26 standards.
