Power system is composed of power plant, substation, transmission line, distribution system and load. It is one of the most important and complex engineering systems in modern society.
In modern power system, large interconnected power grid may be completely interrupted, and power system relay protection provides a complete power plant, so they can respond to these disturbances quickly and correctly. The fire sleeves can protect the electrical pipeline from the influence of long service life and excellent electrical performance. It has properties of high thermal deformation temperature, low temperature impact resistance, safe and durability. Good toughness, good rigidity, good wear resistance, strong corrosion-resistance, good tensile and bending.
The electrical performance of our fire sleeve is little affected by temperature and frequency. Therefore, they are a kind of stable electrical insulation materials, which are widely used in power system.
