Product Introduction

  The umbrella skirt sheath material of 330kV suspension composite insulator is organic polymer material, with low surface energy and strong water repellent. The water falling on the surface of the skirt condenses into many water droplets separated from each other and does not form a continuous water film conductive layer, thus the leakage current is small and it is difficult to form a local arc, and it is not easy to occur along the surface fouling flashover.

    In order to reduce the line lightning accidents, improve the reliability of power supply composite cross-arms insulators can effectively use the narrow corridor open voltage power supply, suitable for urban network technology transformation, can reduce the height of the tower, can save a lot of manpower, material and financial resources, due to its high bending strength, can prevent the porcelain cross-arms easy to appear cascade fracture accident, is the porcelain cross-arms can not replace the product.

Advantages

•  Combine with the current research results of water repellency of silicone rubber materials, adding more than 4 kinds of silicone materials with different molecular weight, polymerization degree and viscosity to improve the water repellency, migration, recovery and durability of the umbrella cover materials.
• The hardness of the vulcanized rubber is controlled at 65-68 (Shore hardness) to ensure that the umbrella cover material has a certain ability to resist external deformation.
• Determine the ratio between silicone rubber, silica and aluminum hydroxide through a large number of tests
