china factory 150A three phase four wire mobile non-spark ex-proof plug socket

15A~200A YT/GZ,YZ series non-spark electric connector is suitable for petroleum exploration,borehole electric control and other electrical continuity,which comply with the relevant regulations is National Standard GB3836.8-2003 & the provision of Europe Standard EN60079-15:2005 “Electrical Apparatus for Explosive Gas Atmosphere Part 8: Type of Protection'n'''.Explosion-proof sign is ExnAII T4,EExnA II T4.

The electric connector consists of two parts:Plug&Socket, of which the plug is mobile(YT).Three kinds of options are made available in the sockets,namely,1 fixed socket(GZ),2 mobile plug(YZ),3 title-type fixed socket(XGZ).Coupling way of the plug and socket is soiral bayonet snap coupling.End connection form between the contacts and wires is crimping.The contacts use elastic rin to support positioning and re the structure of installing from the rear and removing from the front.ZL-102 die-casting alloy is applied in the connector assembly,the contact element is plated with silver,which ensured reliable contact,convenient wiring,better air tightness & insulation,together with such features are waterproof,dust prevention,shockproof,etc.
