Product Manufacturing Process

The glass insulator drawing process at our factory starts with carefully selected raw materials like silica sand, soda ash, and limestone, which are fused at high temperatures to form a homogeneous glass mixture. This molten glass is then molded using advanced mechanical presses, ensuring accurate shapes required for superior insulation. A crucial step is annealing, where insulators are gradually cooled in a controlled environment to eliminate internal stresses and enhance durability. Finally, products undergo stringent quality checks, ensuring they meet international standards.

Product Application Scenarios

Glass insulators are essential in high-voltage transmission lines and substations. They provide critical insulation and mechanical support, thus preventing electrical faults and ensuring operational continuity. Given their non-conductive nature, they are ideal for various high-stress environments, such as coastal areas with high pollution levels. Their robustness and reliability make them indispensable in modern power distribution, maintaining efficacy even under harsh weather conditions.
