Insulators are the most widely used basic components in medium and high voltage power transmission and distribution systems, which are used to insulate and support live parts. A composite insulator is a polymer composite insulator supported by an epoxy pull rod and insulated by a silicon rubber umbrella skirt. Compared with traditional ceramic and glass insulators, this product has the remarkable advantages of lightweight (only 1/4 to 1/8 of traditional insulators for the same purpose), high strength (tensile strength and bending strength of drawbar are more than 10 times that of high-strength porcelain), less pollution resistance and less cleaning (silicone rubber has unique strong hydrophobicity), and overcomes the aging life problem of conventional polymer materials, which can be safely used for decades. It is a new generation of products popularized in the power system.
Product Advantage
1. Insulators are mainly used to isolate high-voltage wires and maintain contact between wires and supports, and are an important part of the electrical industry.Ensure the safe operation of power equipment and electrical systems.
2.Insulators are extremely durable and long-lasting, can be used for a long time, cost-effective, and can perform well in harsh and high-temperature environments.
3. Insulators are widely used in the electric power industry, its material has the ability to prevent corrosion and chemical damage, suitable for use in harsh environmental conditions, in addition, it can be very good protection of electrical equipment, reduce the risk of accidents and normal operation.
4. In terms of safety performance, its irreplaceable, durability, whenever the insulator is the most preferred choice.
