The surge arrester is shown in Figure 7. It is built-up of 6 separate mechanical and electrical modules connected in series. The design of each module includes an HTV silicone rubber insulator moulded directly onto the internal structure with the  ZnO block column. The internal cage-style mechanical structure provides high mechanical strength and well controlled short-circuit capability in the event of arrester overloading.

The special location of the  arrester in the tower has required extensive 3D electrical field calculations to determine necessary grading rings to control the voltage distribution along the  arrester. The mass of the  arrester including the grading rings is 128 kg or approximately one third of the mass of an equivalent  arrester with porcelain housing. The creep age distance of 27 mm/kV corresponds to IEC class III.

Tantalum capacitors are under some conditions prone to self-destruction by thermal runaway. The capacitor typically consists of a sintered tantalum sponge acting as the anode, a manganese dioxide cathode, and a dielectric layer of tantalum pentoxide created on the tantalum sponge surface by anodizing. The tantalum oxide layer may have weak spots that undergo dielectric breakdown during a voltage spike. The tantalum then comes to direct contact with manganese dioxide and the leakage current causes a local heating; a chemical reaction then produces manganese(III) oxide and regenerates (self-heals) the tantalum oxide layer.

About

Kingtronics International Company was established in 1995 located in Dongguan City of China to handle all sales & marketing for factories located in Chengdu, Sichuan and Zhaoqing, Guangdong, China. In 1990, we established the first factory to produce trimming potentiometer and in 1999 we built up new factory in Zhao Qing, Guangdong. Now with around 850 workers, Kingtronics produce trimming potentiometers, dipped tantalum capacitors, multilayer ceramic capacitors, and diode & bridge rectifier. We sell good quality under our brand Kingtronics, and Kt, King, Kingtronics are our three trademarks. All our products are RoHS compliant, and our bridge rectifier have UL approval. Please visit our Products page, you could please download all our PDF datasheet and find cross reference for our Trimming Potentiometer and capacitors.
