By certification 
The 132 kV power line composite insulators have been tested and certified by IEC (International), VEIKI, they are light in weight and have demonstrated fixed contamination levels, withstanding voltage characteristics and shock resistance.
Â
The umbrella sleeve and skirt have good water repellency, aging resistance and chemical stability, which are wrapped around the outside of the mandrel to protect the mandrel from atmospheric erosion and have excellent insulation properties, while the umbrella sleeve and skirt provide the required creepage distance to ensure that the product has good electrical performance.
Â
(1) Adopting the most advanced up-cylinder type silicone rubber injection molding equipment
(2) Adopting advanced product ejecting and moving out mechanism and avoid the damage to the mandrel caused by uneven force and excessive prying angle in the process of artificial prying, and improve the quality of products
(3) Adopting new far-infrared wind circulation heating structure oven with independent intellectual property rights and the good uniformity of the cured film after the core rod is coated to ensure the quality of the bond
