The scope of using the serial of MPG
The serial production of MPG was wildly applied for the trade of electric of electric power, main used for power bus-bar insulation protection in power distribution cabinet or powerbus-bar insulation
protection of indoor or outdoor in the distribution station, etc.It can not only improve insulation propery, shorten the distance between the phase or to the earth, minimize the distribution cabinet,save using square, but also avoid occurring short circuit by small animals in the power distribution cabinet.
