Product Detail

SGL series load isolation switch(hereinafter called switch for short)is manufactured by our company with the up-to-date technique imported from europe.This product meets the international technical level in the late 1990s,being the most ideal renewal of domestic congeneric products.
　　This kind of load isolation switch is widely used in the distribution system and automatic system of architecture,electrical power,petrochemical,and other industries.
　　This kind of load isolation switch possesses flexible structure of modularized design,possesses flexible and veraatile compositionality,it adopts the shell made by unsaturated polyester resin reinforced by glassfibre.It has very high dielectric performance,protective capability,and reliable operation.
　　The operating mechanism is an elastic-accumulating accelerating mechanism for instant release,which makes instant on and off of the double breakpoint contact.It has no relationship with the speed of operating handle and increases greatly various electric properties and mechanicl properties.
　　Many forms of structres and operation in which the on and off state of contact is observed through windows.There are operations inside and outside the board.There are frontal and lateral operations.There are connections behind the board.
　　This kind of switch has good-looking outline and various functions,being very novel,simple and small dimensioned,and the best choice among the congeneric products.
