TBP Medium high voltage combined overvoltage protectorDetailed product description：

The TBP medium and high voltage combined overvoltage protector is a product that has been researched and developed for many years, integrating the advantages of domestic and foreign peers. In the 1990s, it was launched as the smallest, lightest, best sealed, and superior overvoltage protector in China.

The three-phase combined overvoltage protector, also known as TBP, is a new type of overvoltage protector that replaces traditional lightning arresters. It can reliably protect the protected electrical equipment from phase to ground and phase to phase overvoltage, protecting the insulation of the protected equipment from damage caused by lightning and operation overvoltage. It is incomparable to ordinary zinc oxide lightning arresters.

Selection:
Users can choose corresponding overvoltage protectors according to the different protected electrical equipment, with voltage levels including 380V, 3kV, 6kV, 10kV, 35kV and other specifications and applications for users to choose from.

Structural characteristics and installation dimensions of TBP high-voltage combined overvoltage protector:
This product structure adopts a four-star connection method, and overvoltage protectors A, B, C, and D are respectively led by high-voltage cables, greatly reducing the phase to phase distance. Due to the use of a symmetrical structure, any three of them can be connected to phases A, B, and C respectively, with the other phase grounded.

Purpose:
TBP medium and high voltage combined overvoltage protectors are mainly used in power plants and factory electrical systems to protect electrical equipment such as transformer switches, busbars, motors, generators, lines, and capacitor banks, limit atmospheric and operational overvoltages, and provide reliable protection for electrical equipment.  

Main parameters of overvoltage protector: [No W for indoor type, W for outdoor type]
