Stable Insulating Ability GB / DL mechanically held vacuum lighting magnetic contactors The Main Features Of Embedded Pole ◆High Reliability And Stability Compared with assembly pole, embedded pole use much less spare parts, conductor faying surfaces and jointing fastening piece, so that simplify the conductance circuit’s assembly links, lower the circuit’s resistance and improve galvanic circle’s reliability and stability. ◆Stable Insulating Ability Vacuum interrupter
