800kv Composite Long Rod Polymer Insulator

1. Different strengths and coupling fittings are available.

2. Below 220kV electrical data shown for composite line post insulators without corona rings and mounted vertically. Wuhan Line Power recommends corona rings to be installed at 220kV and above.

3. Additional section lengths and creepage distances are available. Contact the sales agency for details.

4. All dimensions, tolerances, and tests are within allowable IEC standards or ANSI standards.

5. All dimensions are in millimeters(mm). If in inches and pounds, please specify.

6. We can design according to the end user's requirements.

1. The silicone rubber housing of the Composite Line Post Insulator is shaped by whole injection. It has good hydrophobicity, hydrophobicity migration, and soil resistance, as well as excellent electrical insulation properties and aging resistance, which can effectively prevent accidents related to pollution flashover and ensure the safe operation of high-voltage transmission lines.

2. The modified ECR fiberglass reinforced epoxy resin rod is used because it has good resistance to high temperature, stress corrosion, and acid attack, as well as fine damping action, high tensile strength (> 1200Mpa), and resistance to creep and fatigue failure, which effectively ensure the internal insulation quality and mechanical strength of the insulator.

3. End fittings are crimped onto fiberglass rod with a voice-operated displacement type crimper. Insulators with this crimping technique have high mechanical strength and small dispersion. Taking the most advanced automatic overall injection molding technology and connection method of crimping for production and assembly, and the whole crimping procedure controlled by computer and the crimping result monitored by ultrasonic detector to assure each product is qualified.

Wuhan Line Power Transmission Equipment Co., Ltd. is mainly engaged in the research, development, production and sales of high-voltage transmission composite insulator series products, the core technology from Wuhan University (former Wuhan Institute of Hydropower), Hubei Institute of Chemical Technology, Wuhan High Voltage Research Institute and other scientific research institutions.

In order to adapt to the development needs of the industry, the company was restructured by the scientific and technical personnel and engineers in the field of composite insulators combined with the national capital, and has now developed into a new type of modernized enterprise integrating scientific research, production and sales. A series of mature composite insulator products have been formed at the beginning of the company's establishment. The company's core team members in technology, production and management all have more than 20 years working experience in the same industry. The excellent core team ensures the company's high starting point in technology and products.

With strong strength, reasonable price, good service and many enterprises to establish a long-term partnership, with high quality products and perfect after-sales service, won the praise of customers all over the country, and sincerely welcome domestic and foreign merchants to visit, investigate and negotiate business cooperation.
