The power industry is mainly a power production and distribution system composed of power generation, transmission, transformation, distribution and sale. With strong inspection capabilities, NMEI Center offers a full set of technical services featuring a wide index range to a broad scope of products, meeting the inspection requirements of high-voltage electrical products in the power industry, especially the marine electrical products.
The large capacity system is used to carry out short-circuit test to breakers, switch cabinets, load switches, fuses and combined electrical appliances. Insulation tests, lightning impluse tests, partial discharge tests can also be launched. NMEI Center is capable for characteristic environment salt-spray test, pollution test, rain test, vibrations test, swing test, IP degree test, high and low temperature test, etc. At the same time, the laboratory has the ability of temperature-rising test and mechanical test.
