Gelonghui April 3 丨 Dalian Electric Porcelain (002606.SZ) said on the investor interactive platform that currently the company does not produce glass insulator products. Currently, insulators made of the three materials of porcelain, composite, and glass, which are widely used by power users, have advantages and cannot be completely replaced. Insulators of the corresponding materials are selected in different transmission lines according to geographical, climatic, environmental and other factors of the route region. In the last ten years, under the leadership of our company, porcelain insulators have made major breakthroughs in the two key technologies of formulation and structure, greatly improving product stability and providing better guarantees. This makes porcelain insulators ahead of the other two material products in stages.
