Description

FD3 320/50 320V 50KA Power Surge Protector applied primarily to the main distribution system surge protection unit

Operating Principle

Edge discharge technique is used for this device. The electrode is in the shape of angle.Two electrodes are placed face to face, and kept a certain distance between them by an insulating block made from special materials. There is an arc quenching baffle plate in the arc quenching chamber located under the electrode, which will be edge discharging at the surface of the insulating block when over-voltage is coming. The arc is forced outwards due to the angle shape structure of the electrodes and then split into many sub-arcs against the baffle plate. These discharge features are favorable for the arc quenching process after the discharge finished, and thus limiting the follow-through current caused by discharging.

Application

The device is applied primarily to the main distribution system. It can suppress the direct lightning over-voltage or inductance over-voltage with high energy appeared in the lines of low voltage power system, to protect the buildings and various outdoor installed apparatus in the Class 1 lightning arresting area, which are likely to be stroke by lightning.

The company has the largest production scale of Varistor,SPD( Surge Protective Device)and HV Ceramic Capacitor in China, with the following main products :

1. Varistors & SPD

2. HV Ceramic Capacitor
3. Capacitive Voltage Divider

4. Thermistor

The main production line and inspection equipment & instrument are imported from Japan, America, Belgium and Switzerland etc. The annual production capacity of the two leading products has been reached to 5 million pcs and 150 million pcs respectively, with the market holding rate in China of about 10% and 30% respectively by continually technical innovation. Varistors and SPD produced by the company enjoyed great reputation in the international market, being exported to many countries and areas such as Japan,USA, Hong Kong etc., with the customers like India and GE in USA. are already sold to LG company in Korea with large quantity, and also to Spainand India etc.

Not only the products quality and technical capacity, but also the completeness of the models are all in the leading place in China. The main products have got CCEE, UL, VDE & TUV approval. The quality system was set up according to the requirement of ISO9000 since 1992, and has passed ISO9002 approval by DNV International Organization in July 1994, then got ISO9001 certification by British organization in 2000, by then we are both the first one who are approved by ISO9000 certification in the North-west area of China and the same occupation. We passed all the successive periodical audit and smoothly get the new certificate registered in Holland in Aug.1997; the quality system is strengthened and completed constantly. And we also got ISO18000 certificate.

We believe we are able to supply satisfied goods and service to customers home and abroad with the most reasonable price and the shortest delivery time, on basis of our excellent quality assurance capacity, technical development capacity and rich manufacturing experiences.
