INSULATORS

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.

This product is used in power generation, transmission, transformation, and distribution systems of AC 220kV and below, and is used to insulate and support live parts.

The product model is prepared according to the provisions of JB/T 9683-1999 Preparation Method for Insulator Product Models, and the configuration parameters are in accordance with JB/T 5892-1991 Technical Conditions for Organic Composite Insulators for High Voltage Lines and JB/T 8737-1998 Guidelines for the Use of Composite Insulators for High Voltage Lines.

The important parameters and configuration methods not clearly defined in the above standards shall be corrected according to the requirements of GB 311.1-1997 Insulation Coordination of High Voltage Power Transmission and Transformation Equipment and GB/T 5582-1993 Pollution Level of External Insulation of High Voltage Power Equipment.

MODEL AND MEANING

USAGE: ENVIRONMENTAL CONDITIONS

1. Ambient temperature: no higher than+40 ºC, no lower than - 40 ºC
2. Altitude: no more than 3000 m;
3. Power frequency: no more than 100Hz;
4. Mechanical load: no more than the rated value of each product.

During the use of suspension insulators, it may cause flashover accidents due to the accumulation of bird droppings, and even lead to the disconnection of the power grid. The extra large umbrella skirt structure can effectively prevent other umbrella skirts and grading rings from being polluted, eliminate such potential accidents, and increase the anti-ice flashover ability of insulators in the north and alpine snow areas.

When the angle between the line direction and the wind direction is greater than 45 °, the conductor is prone to galloping, threatening the safe operation of the power system. The suspension insulator grading ring is designed as a heavy hammer structure, which can effectively reduce the natural frequency and amplitude of the insulator's transverse vibration while improving the end electric field distribution, and is suitable for use in the northwest strong wind and sand area and valley tuyere.
