Polymer Housed Mate High Voltage Line Type Lightning Protection Zinc Oxide Surge Arrestors  

Product Description

 

 

 

The arrester is connected between the cable and the ground, usually in parallel with the device to be protected. The arrester can effectively protect the communication equipment. Once the abnormal voltage occurs, the arrester will act to protect the equipment. When the communication cable or equipment is operating at the normal operating voltage, the arrester will not be effective, to the ground as a circuit breaker. When a high voltage occurs and endangers the insulation of the device to be protected, the arrester acts immediately to direct the high voltage impulse current to the ground to limit the voltage amplitude and protect the insulation of communication cables and devices. When the overvoltage disappears, the arrester quickly restores the original state, so that the communication line can work normally.

Therefore, the main function of the arrester is to cut the amplitude of the intrusion flow wave through the function of parallel discharge gap or nonlinear resistance, and reduce the overvoltage value of the protected equipment, so as to protect the communication line and equipment.

Arresters can be used not only to protect against high voltages generated by lightning, but also to protect against high operating voltages.

The role of lightning arrester is used to protect all kinds of electrical equipment in the power system from lightning overvoltage, operating overvoltage, power frequency transient overvoltage impact and damage to an electrical appliance. The main types of arrester are protection gap, valve type arrester and zinc oxide arrester. The protection gap is mainly used to limit atmospheric overvoltage, and is generally used to protect the incoming line segment of the distribution system, line and substation. Valve type arrester and zinc oxide arrester are used for the protection of substation and power plant. In 500KV and below system, they are mainly used to limit atmospheric overvoltage. In ultra-high voltage system, they will also be used to limit internal overvoltage or backup protection of internal overvoltage.

Wuhan Line Power Transmission Equipment Co., Ltd. is mainly engaged in the research ,development,production and sales of high voltage transmission power composite insulator series products.The core technology comes from the scientific and research institutions such as Wuhan University (originally Wuhan University of Water and Electricity),Hubei Institute of Chemical and Industry and Wuhan High Pressure Research Institution and so on.

In order to adapt to the industry development demands,it was reformed in combination with national capital by the scientists and engineers who are in the field of composite insulator.Now it is restructured as a new modernized enterprise which integrates research ,production, marketing and sales. The company had formed a series of composite insulator mature products at the beginning of its establishment. These products have been widely used in power, railway and other industries for many years.The core team members of company technology, production and management have more than 20 years of working experience in the same industry. The excellent core team ensures the high starting point of the company in technology and products.

Our company with strong strength, reasonable price, good service and a number of enterprises to establish a long-term partnership.With high quality products and perfect after-sales service, we have won the consistent reputation of customers all over the country.We sincerely welcome customers from home and abroad to visit, investigate and discuss business cooperation.
