Product Details

QGL(HGL) series load isloation switch (hereinafter called switch for short) is manfactured by our company with the up-to-date technique imported from Europe .This product meets the international technial level in the late 1990S.Being the most ideal renewal of domestic congeneric products.

This kind of lode isolation switch is widely used in the distribution system and automatic system of architecture,electrical power,petrochemical,and other industries.

This kind of lode isolation switch possesses flexible structure of modularized design,possesses fiexible and versatile 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 elatic-accumlulating accelerating mechanism for 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.

Many forms of structres and operations 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 poerations.There are connections behind the board .

This kind of swich has a good-looking outline and various functions ,being very novel,simple and small-dimensioned ,and the best choice among the congeneric prouducts.

The QGL(HGL) series prouduct has acquired the 3C attestation certificate.
