Decoupler Series TOQ 35A 63A coupling device widely used in multi-level protection lines

Decoupler is a coupling device widely used in multi-level protection lines, and is widely used in power lines with current less than 63A in power distribution systems. When the lightning current invades the line, the installed decoupler can make the first-level SPD of the line act first, release most of the lightning wave energy, reduce the energy of the second-level SPD, so as to realize a two-level surge protector The cooperation between the two can realize the large inrush current that the system bears, the low residual voltage, and the protection of the subsequent circuits and equipment from overvoltage.

Features

• It is connected in series in the low voltage operating AC power system, with AC 50Hz/60Hz, nominal voltage of 500V or less.
• It is used to increase the inductive reactance of the wire, and make up for the deficiency of the wire length, to make sure for the good match between the lightning protectors of two classes;
• It is used for decoupling between lightning protectors of two classes in one distribution panel;
• Suitable for different networks: TN TT IT

• Maintenance is unnecessary

• Various nominal current choice

Technical Parameters

Operation and Maintenance

• When the installation distance between the switch type surge protector and the voltage limiting type surge protector is less than 10m, or the distance between voltage limiting type surge protectors is less than 5m, decoupler shall be installed between the surge protectors to increase the inductive reactance.
• It is connected in the power system in series. The installation is carried on by skilled electrical staff.Inspection shall be made before the installation, to check if the nominal Un value and In value match with the actual system voltage and current. It shall not be installed if not match or the appearance is damaged.

• Pay attention to the temperature allowance when several decouplers and surge protectors are

  connected together.

• Fix the connection screw regularly, and check the appearance of the device, replace the device immediately if any failure occurs.

COMPANY OVERVIEW

Xian Xiwuer Electronic & Info. Co., Ltd. is located in Beiguan, Xi'an city cover in an area of 4000 ㎡, with employees of 2300, and about 580 technicians, amongthem, there are 135 engineers, 21 senior engineers. The company has total assets of 315 million RMB Yuan, fixed assets of 137 million RMB Yuan, which is a large enterprise mainly engaged in producing electronic components. 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

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.
