With the improvement of our country’s industrial production level, the requirements of enterprises on production environment and personnel health are increasing in both traditional and new fields. With these improvements, the application scenario of the fire-proof bushing has developed rapidly, and the substation cable protection is a very classic application.
Power System is the basis of national life and production, power system stability is related to all aspects of social life and production, power system relay protection provides the whole system with a fast and accurate, perfect protection processing mechanism. In the course of cable laying, the cable is protected by a fire-proof sleeve, which fully meets the requirements of insulation, high and low temperature resistance, good weather resistance, strong corrosion resistance, tensile resistance and bending, and can be used for a long time from-60 °C to 260 °C to extend the service life of the pipeline, to ensure safe and reliable operation of the transmission inel
