Henan Energy Electric Equipment Co., Ltd. was established in 2011 and is an excellent and reliable power equipment manufacturer in China. The company mainly develops and produces oil-immersed transformers, dry-type transformers, box-type substations, high-voltage switches, and medium and low voltage complete sets of equipment. The equipment put into production and operation of the project advocates energy saving, intelligence, informatization, and mechanization. The company has established the Henan Triangle Energy-saving Transformer Engineering Technology Research Center, with 71 utility model patents and 15 invention patents. With years of accumulation in the transformer industry and strong technological innovation capabilities, HZEC products are sold to the Middle East, North America, South America, Europe, Southeast Asia, Africa, and other regions, covering more than 40 countries.
Product Description
JSZV12-10R voltage transformer is a three-phase, indoor product, suitable for rated frequency 50Hz, rated voltage 10kV and below power system for voltage, electric energy and relay protection. This type of voltage transformer with fusing protection, "V" type connection becomes three-phase, can also be used as two single-phase separately. In addition to the secondary output voltage of 100V for measurement, the product can also be used with 220V operating voltage for power supply of the operating mechanism.
JSZV12-10R voltage transformer is epoxy resin cast insulation, fully enclosed structure. The iron core is made of high quality cold rolled silicon steel sheet, together with the primary and secondary winding cast into a whole, with excellent insulation properties and moisture-proof, anti-fouling ability. The A, B and C phases of the primary winding are each equipped with a circuit breaker matching the transformer's short-circuit bearing capacity, which can effectively protect the transformer from being burned when the power grid fails. The fuse is installed in the primary winding outlet terminal, easy to replace, just take out the front rubber cap and nut can be removed or loaded into the fuse.
