Jinpan International Limited engages in designing, manufacturing, and marketing cast resin transformers and other power control and distribution products in the People’s Republic of China, the United States, and Europe. Its cast resin transformers allow high voltage transmissions of electricity to be distributed to various locations in lower and more usable voltages. The company offers medium voltage cast resin transformers for various end uses and applications comprising industrial, infrastructure, and municipal projects, such as factories, real estate developments, airports, and subway systems. It also provides conventional and high end gas insulated switchgears that control the flow of electricity to and from electrical equipment; vacuum pressure impregnated (VPI) reactors for wind energy applications; VPI transformers, which serve as stand-alone units for power distribution and as components for inverters and converters; variable wattage VPI transformers customized for industrial applications; and unit substations that transform high voltage electricity to lower voltages that feed into distribution transformers, which then lowers the electric voltage to levels suitable for consumer applications. The company sells its products through sales representatives to resellers or end users of power control and distribution equipment, including original equipment manufacturers, utilities, municipal governments, industrial companies, and commercial and residential developers. Jinpan International Limited was founded in 1993 and is headquartered in Haikou, the People's Republic of China.
