Modulus socket SZRB2-AC30AC30 series modulus socket suitable for terminal distribution boxes and other electrical equipment inside the plug on the power equipment, widely used in high-rise buildings, industrial and mining enterprises, station ports, hospitals and other places. Low voltage switch cabinet Fundamentals training materials vacuum switchgear basics in actual use multiple vacuum breaker into the metal cabinet, composed of high voltage switchgear. In addition to the circuit breaker switchgear, also install play the role of isolation circuit isolating switch, from the security role of the grounding switch, measure or protection from the effects of current and voltage transformers, from the over-voltage arrester or protective effect RC absorber, but also install secondary circuit components and circuits, connection of cables or overhead lines can be used for relay into the cabinet, the switch cabinet as a function of a combination of a relatively independent power distribution equipment. In switching stations, transmission lines power plant substation, receives power user terminal substations are extensive use of various switchgear. About 10 years ago, low voltage, equipped with less oil circuit breaker switchgear occupies almost a monopoly in the country, on the street low voltage, but with the rise of a vacuum circuit breaker, low oil switch refuse gradually take a back seat . Since 1993 made 'oil-free transformation' requirements since, Gongyi low voltage, but also contributed to this trend, some provinces even banned the continued use less oil switch in cities and major users of the power grid, station construction He refused, and the old station will gradually be replaced with a vacuum switch less oil switchgear. Tangyin low voltage, low voltage, provided by the Henan Xi Xi Connaught Electrical and Mechanical and Electrical Equipment Co. Connaught. Henan Xi Connaught Electrical Equipment Co. (www.hnxinuo.com) strong, credible, in Zhengzhou, Henan electronics, electrical products processing industry has accumulated a large number of loyal customers.
