Composite Jacket Silicon Rubber Single Phase Lightning/Surge Arrester

Lightning arrester is the foundation of insulation coordination for various electrical equipment in the power system,such as transformers,reactors,capacitors,generators,motors,PT,CT,circuit breakers,contactors,etc.The protection performance of ightning arrester determines the internal and externalinsulation indicators of all electrical equipment in the power system,such as short-term power frequency withstand voltage,lightning impulse withstand voltage,and operating impulse withstand voltage.
Metal oxide lightning arrester,commonly known as "zinc oxide lightning arrester,is a new generation of lightning arrester that was widely promoted internationally in the 1980s by countries such as the United States and Japan.It is the most advanced product among conventional lightning arresters.Since the mid-1980s,China has full introduced thistechnology.Through years of practice and digestion,the performance of AC lightning arresters from various professional lightning arrester factories is currently on par with the most advanced products from countries such as the United States,Japan,and Western Europe.Products that truly meet all the requirements of national standards can also meet the requirements of international IEC standards.
The core working componentsof this productare made of multi-element metal oxide powder mainly composed of zinc oxide,which has excellent nonlinear volt ampere characteristics,fast steep wave response,and large current capacity.The products with gaps adopt self blowing gaps and a uniform pressure irradiation structure,which reduces the dispersion of discharge and has a small impact coefficient.
The adoption of composite insulation jackets conforms to the development trend of miniaturization,safety,and maintenance free international power products.Compared with traditional inorganic materials such as ceramics and glass,polymer organic composite materials have the advantages of small olume,light weight,resistance to polltion,cleaning,explosion and vibration, and are the preferred lightning protection components in integrated and modular medium and high voltage transmission and transformation equipment.
