LMHGL series pruduct overview
This kind of Load isolatian swtch is widely used in the distribution system and automalic system of archiladure,electeical power.perrochemical.and other industries.
This kind of Load isolation seitch possesses flexible structure of modularized design.pssesses flexible and versatile compositbonality,it adoptsthe shell made by unsaturaled polyester resin.reinforced by glassfibre.
It has very high dielectric performance.protective capability.and reliable operation.
The operating mechanism is an elatic-accumlating accelerating mechanism for instant release,which makes instant on and off of the doublreakpoim contad,it has no relalionsnip with the speed of operating handle and incresses greatly various electric properties and mechnical properties.
Many forms of structres and operations in which the on and off state of contact is observed through windows.There are operations inside andoutside the board.There are forntal and lateral operations.
There are conncetions behind the board.
This kind of swirch has a good-looking outline and various funtions,being very novel.simple and samall-choice among the congeneric products.

 

LMHGL series features

1.The elastic-acceleration acceleration mechanism for instantrelease realizes the rapid making and breaking(13.8M/S),having no relationship with the speed of the operating handle,and increasing greatly of exingushing electric arc.
2.The shell made of unsaturated polyester resin reinforced by glass fibre possesses excellent performance of flame resistant,dielectic performance,safe opration,resist carbonic performance and resist impact perdormance.
3.Parallel double gap contact posseesses self deaning functions.
4.ALL the contace materials are copper alloy plaetd with silver,and possess two separation contace surfaces.
5.Large insulation distance.
6.Be on "O",the products can lock the handle with three lockes at the same time and thus can aviod error operation.

Product display

Operation environment

LM(HGL)series load isolation switch can work reliably under the folwing condition
1.Height abovt sea level does not exceed 2000m
2.Ambient temperature is not higher than +40℃~and not lower than-5℃,relative humidity is not lager than 95%.
3.No explosive dangerous medium environment
4.No rain and snow attack environment
NOTE:If the load isolation switch is exoected to be used in the conditon that the ambient temperature is highter than +40℃ or is lower than -5℃~-45℃ cuetormers should inform to the manufactory

 

LM(HGL)-63A-3150A load break switch

1.7 specifications of LM(HGL)load isolation switch from 63A to 315A Basic of modularized design,possesses three poles,and four poles(3 poles+on and off neutral pole).It is suitable for electric isolation.Switches over 1000A are only suitable for electric isolation.
2.Mark winkow is set in the front side to indicate the on andoff state of the contact
3.Rear observation window can be provided according to the demand to observe directy the on and off state of the contact
4.For window pattern,refer to the back oprational load isolation switch,LM(HGL)-160A~1600A/H.
5.Two sets of auxiliary contacts can be assembled according to demand.
6.The eletric cable insulating cover can be assembled.
