Kingtronics surge arrester divides into two kinds: 2-Electrode arresters and 3-Electrode arresters.

What is surge arrester? It is a product installed near the end of any conductor which is long enough before the conductor lands on its intended electrical component. The purpose is to divert damaging lightning-induced transients safely to ground through property changes to its varistor in parallel arrangement to the conductor inside the unit.

Surge arrester is also called a surge protection device (SPD) or transient voltage surge suppressor (TVSS). They are only designed to protect against electrical transients resulting from the lightning flash, not a direct lightning termination to the conductors.

Telecommunications installations as well as CATV amplifiers, CB transmitters, home entertainment systems, computers and similar equipment can be exposed to voltage surges conducted via the power network. The combination of a surge arrester and a varistor offers proven protection in these cases. The phase and neutral conductors are connected to ground potential of both protection elements.

The capability of the surge arrester in energy dissipation against switching surge is well expressed by the magnitude of kJ/kV (arrester rated voltage). These values show the dissipated total energy per two shots of switching surge that the surge arresters can withstand thermally with these values. Where the energy capability is inadequate in our standard series.

Typical structure of surge arresters are shown in Figure below .The surge arresters are basically composed of the TNR elements, housing and associated parts with insulating gas filling as shown in figures. The hermetic sealing of the housing is constructed with weather-proof synthetic rubber. The pressure relief diaphragm is structured with special metal plate, which is ruptured when a sudden pressure rise occurs in case of the internal failure.

The principal "active" element of the Surge Arrester is a metal oxide varistor characterized by high non-linearity. At a working voltage mainly a capacity current flows smaller than 1 mA. Any voltage increase causes a large increase of current flowing through the varistor, leading in turn to immediate limitation of further voltage increase on arrester terminals. When the over voltage disappears, the arrester immediately returns to its basic state.

Surge Arresters are equipped with a disconnecting device that disconnects the arrester from the network if it becomes damaged as the result of over voltage of too high energy or inadmissible voltage increase in the system. If such a situation occurs then the bottom terminal of the disconnecting device is "rejected" by the spring inside. This terminal remains suspended on an insulation "leash".

Kingtronics sell 2-Electrode arresters and 3-Electrode arresters. Following are 2-Electrode arresters and 3-Electrode arresters’s pictures.

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.
