Industry overview

YH composite jacket zinc oxide arrester is the basis of insulation coordination of various electrical equipment (transformers, reactors, capacitors, generators, motors, PT, CT, circuit breakers, contactors, etc.) in the power system. The power system is determined by the protection performance of the arrester. Internal and external insulation indicators of all electrical equipment (short-time power frequency withstand voltage, lightning impulse withstand voltage and operating impulse withstand voltage, etc.).

Solution

The nuclear working component of the product is fired by a multi-metal oxide powder mainly composed of zinc oxide, which has excellent nonlinear volt-ampere characteristics, fast steep wave response and large flow capacity. The gap product adopts a self-blowing gap and a uniform pressure irradiation structure, which reduces the dispersion of the discharge and has a small impact coefficient. The adoption of composite insulation jackets conforms to the development trend of miniaturization, safety and maintenance-free of international power products. Compared with traditional inorganic materials such as ceramics and glass, polymer organic composite materials have small volume, light weight, pollution resistance, cleaning, explosion-proof and shockproof.

Lightning arrester

Metal oxide surge arresters, commonly known as "zinc oxide arresters", are the new generation of arresters that have been popularized in the United States in the 1980s by the United States, the United States and other countries. They are the most advanced products in conventional lightning arresters. Since the introduction of this technology in China in the mid-1980s, through the practice and digestion for many years, the current performance of the lightning arrester of various professional arrester factories is comparable to that of the most advanced products in the United States, Japan and Western Europe, and truly meets all the requirements of the national standard. The products can also meet the requirements of international IEC standards.
