GW9-12 outdoor 10kV pole mounted knife switch disconnector
LSOLATING SWITCH
GW9-12 series isolating switch is single-use for three-phase line system, simple in structure, economical and easy to use;
This product is a single-break vertical open structure, and the single-stage isolating switch post insulators are installed on their respective chassis, mainly composed of base, post insulator, main conductive circuit part, self-locking device, etc.
The guillotine structure is used to switch on and off to cut off and close the circuit. Each phase of the knife is composed of two conductive blades, and the two sides of the blade are equipped with compression springs, and the contact pressure required by the switch knife can be obtained by adjusting the height of the spring. When the switch is opened and closed, an insulating hook rod is used to operate the mechanism part, and the knife has a self-locking device.
(H) Gw9-10 outdoor high-voltage disconnector is a single-phase AC 50Hz high-voltage switchgear, which is used to connect or isolate the power supply under the condition of voltage and no load in the power system with rated current less than 10kV.
The disconnector is operated with an insulating rod.
