Classification and function of High Voltage Switchgear High Voltage Switchgear cabinet equipment for electrical power systems. High Voltage Switchgear Process role in the power system for power generation, transmission, distribution and power conversion, and low voltage switch, opening and closing, control and protection. High Voltage Switchgear unit within the main high voltage circuit breakers, high voltage isolation switch, high voltage load switch, high voltage operating agencies. Classification of High Voltage Switchgear many, such as through the circuit breaker can be mounted into withdrawable and fixed high voltage switchgear high voltage switchgear, or in a different cabinet structure, Henan low voltage switch cabinet, high-voltage switch into open cabinets, metal-enclosed box-type high voltage switchgear, metal-enclosed high voltage switchgear and interval-type metal-enclosed high voltage switchgear and other armored. Air-source heat pump water heater internal structure consists of four core components: a compressor, a condenser, an expansion valve, an evaporator refrigerant composition as well as the temperature of the carrier. For now developed the environmentally friendly refrigerant refrigerant compressor comprising: C02, R134a, R410A, R417A refrigerant compressors, etc.. Water temperature up to 80 ℃, you can even reach 90 ℃ Zhengzhou, where low voltage switch cabinet cheap, low voltage, provided by the Henan Xi Xi Connaught Electrical and Mechanical and Electrical Equipment Co. Connaught. Zhengzhou, where low voltage switch cabinet cheap, low voltage, Xi Xi Henan Connaught Connaught Electrical and Mechanical Electrical Equipment Co., Ltd. (www.hnxinuo.com) this year introduced a new upgrade, the above picture is for reference only, please call or pictures on this page contact telephone number, to obtain the latest information, contact: Yang Yongjie.
