Our vulcanization workshop is a critical stage in the production process, where we enhance the durability and performance of our insulators. During this phase, we subject the product to a precise vulcanization process, ensuring optimal adhesion between the silicone rubber housing and the fiberglass core. This step significantly improves the insulator’s mechanical strength, weather resistance, and electrical insulation properties.

Once vulcanization is complete, we proceed with a comprehensive series of quality assurance tests. These include high-voltage tests, where the insulator is subjected to extreme electrical stress to verify its dielectric strength and resistance to flashovers. Additionally, we perform mechanical load tests to assess its ability to withstand operational forces, as well as aging and environmental resistance tests to ensure long-term reliability in various harsh conditions.

Finally, our experienced quality control team manually inspects each insulator, conducting thorough visual and functional checks to confirm that it meets our strict industry standards. Only after passing all these rigorous inspections is the product approved for shipment, guaranteeing that our customers receive a safe, high-performance, and long-lasting solution for their power transmission needs.
