Product Description

HY Series Metal Oxide Arrester HY Series MOA Brief Introduction Arrester is the basis for insulation coordination of various types of electrical equipment in power system (transformers, reactors, capacitors, generators, engines, PT, CT, circuit breakers, contactors, etc.), according to arrester protection performance to determine the internal and external insulation indicators of all electrical equipment in power system (short-term frequency voltage, lightning impulse voltage and switching impulse withstand voltage, etc.). Metal Oxide Arrester, commonly known as "Zinc Oxide Arrester" is developed and widely use from the United States, Japan and other countries from ***0s, is the most advanced of conventional products. In the middle of ***0s, China introduced this new technology, through many years’ practice, recently all professional arrester plants’ performance have been met the U.S., Japan, Western Europe and other countries standard, thereby achieving all the requirements of international products meet all the requirements of the international IEC standards. Core components of this product make by zinc oxide-based multi-metal oxide powder burning, have excellent nonlinear electrical behavior, and steep wave fast response, large current capacity. With both pressure light structure and reduce the discharge of the dispersion, the impact coefficient. Using of compound insulation jacket comply with the international small power products, security technology, maintenance-free trend. Organic polymer compound materials compared with traditional inorganic materials, ceramics and glass materials, it has more advantage such as small size, light weight, resistance to contamination-free clean-up, explosion-proof anti-vibration and so on. This product is preferred lightning protection elements in integrated, modular high voltage power transmission equipment.
