TBP-310 Three-phase Composite Surge Arrester,fuse protecttion,lightning protector,porcelain lightning arrester TBP Series Three-phase Composite Surge Arrester (Over voltage protector) Brief Introduction As widely use of vacuum switches, it raised new project about their ability automatically break to protect of all kinds of operation voltage in power equipment. Due to some peculiarities for our medium voltage power grid (3 66kV), the standard medium voltage arresters is not sensitive to operating voltage and no protection. TBP Phase Combined overvoltage protector (also known as YH three-phase combined arrester) is new product precisely to address this problem. Such products adopt four star connection (commonly known as the trigeminal dry connection) to set the public neutral point which not only can reduce phase over voltage, but also improve the quality level of relative protection, thus playing the role of the vacuum switching overvoltage effective restrictions. Our company's products adopt compound insulation, compact structure, sulfide fully closed shape. Use high-quality metal-oxide valve and boast special clearance, good performance and high safety and convenience. Particularly suitable for KYN, XGN, GBC, JYN, GZS and other different types of medium voltage switchgear cabinet or directly installed in the small box-type substation.
