XUCKY Electric is a large GW4-11kv Outdoor Disconnector manufacturer and supplier in China. Disconnector (hereinafter referred to as isolation switch) is a three-phase AC outdoor high voltage switchgear with rated frequency of 50Hz and rated voltage of 110kV, to make and break high voltage circuit with rated voltage of 110kV when having voltage and no load. The isolation switch meets the requirements of GB1985-2004 AC High Voltage Isolation Switch and Grounding Switch.

Q2 Automatic Transfer Switch (hereinafter referred to as ATS switch, also known as home transfer switch) for dual power supply system of AC 50Hz, rated voltage of 380V, rated current of 63A~630A, use automatic or manual operation modes to switch between the common power supply and standby power supply. The home transfer switch is mainly used for hospitals, shops, banks, chemical industry, metallurgy, high-rise buildings, military facilities and other important occasions.

3kv-36kv Zinc Oxide Lightning Arrester is a device to protect electrical equipment from overvoltage transients caused by external (lightning) or internal (switching) events. Also called a surge protection device (SPD) or transient voltage surge suppressor (TVSS), this class of device is used to protect equipment in power transmission and distribution systems. (For consumer equipment protection, different products called surge protectors are used.) The energy criterion for various insulation material can be compared by impulse ratio, the surge arrester should have a low impulse ratio, so that a surge incident on the surge arrester may be bypassed, to the ground instead of passing through the apparatus.

China XUCKY Electric customized JDZX9-35 Type Voltage Transformer. There are three primary types of voltage transformers (VT): electromagnetic, capacitor, and optical. The electromagnetic voltage transformer is a wire-wound transformer. The capacitor voltage transformer uses a capacitance potential divider and is used at higher voltages due to a lower cost than an electromagnetic VT.

Q3 Automatic Transfer Switch (hereinafter referred to as ATS), it is suitable for the power supply system of AC 50Hz, rated voltag f 400V, rated current of 63A and below. Choice and conversion between two power supply according to the needs. ATS have protection functions of overload, short circuit, under-voltage, but also have functions of fire, double breaking and output closing signal. Particularly applicable to the lighting lines in office buildings, shopping malls, banks, high-rise buildings and other places with needs of the fire.
