The silicon carbide insulating protective sleeve is resistant to high temperature and corrosion , and is widely used in various electric furnaces using silicon carbide rods . The sleeve is used together, which can effectively prevent the silicon carbon rod electric heating element from contacting the protection tube, and has a very good insulation effect.

The silicon carbon rod insulating protective sleeve not only plays the role of electrical insulation, but also plays the role of fixing the silicon carbon rod. The service life of the ordinary silicon carbon rod insulating sleeve is 1-2 years.
