Ping An Electrician (001359.SZ) stated on the investor interaction platform on June 13 that mica has high insulation strength, large resistance, low dielectric loss and arc resistance, and excellent dielectric properties such as anti-electricity and electrical coronas. The refractory mica strip produced by the company is commonly used as a heat-resistant material for wires and cables, which can withstand high temperatures caused by too much resistance in the circuit, reducing the probability of circuit fires and increasing the safety of power transmission. In the process of building a national interconnected power grid pattern in China, the state is steadily promoting the construction of physical infrastructure of the national power grid with ultra-high voltage power grid as the backbone network and coordinated development of various levels of power grids, and the power market is steadily developing, bringing about a large demand for mica insulation materials, and the company's refractory mica strip products are widely used in the field of wires and cables.
