Our special insulation sleeve is a safe and reliable product that helps protect power transmission systems from the effects of overvoltage. Designed for use with ultra-high voltage (UHV) arresters, it is made from robust materials capable of withstanding harsh weather and other adverse conditions. Its function is to provide excellent electrical insulation and prevent erosion and tracking. It is easy to install, has a long service life, and is a cost-effective solution for protecting UHV arresters. Our special insulation sleeve meets international safety standards and is used in power systems around the world.
