115kv 132kv 138kv Composite String Insulators Suspension Silicon Rubber Insulator Price
Product Description
The composite suspension insulator is designed with a compact structure and strong integrity, making it a reliable choice for high-voltage transmission lines. It offers excellent anti-pollution capability, combining light weight with a small volume for easy handling and installation. The insulator is known for its superior internal and external insulation performance, providing high mechanical strength and stability under various operational conditions. Regular cleaning is necessary to maintain its efficiency and longevity, ensuring optimal performance in demanding environments.
The umbrella cover of this composite string insulators is made from a silicone rubber composite material, which significantly enhances its anti-corrosion properties. This material choice effectively addresses issues like rust, especially under adverse weather conditions such as dry climates and acid rain. The silicone rubber cover not only improves durability but also helps in preventing pollution flashover accidents. This results in reduced maintenance and cleaning workloads over the lifespan of the product, offering a cost-effective solution for maintaining high-voltage transmission lines.
