Product Description

Product Description

 

At present, composite polymer tension insulators are widely used in power gridtransmission lines, accounting for about 50% of the line silicone rubber insulator consumption. Among them, the proportion of linear towers is higher. Almost all linear towers in heavily polluted areas use composite insulators. Composite polymeric insulators have solved the pollution flashover problem that has plagued the power grid for many years with their excellent anti-flashover performance.

  

This series of products are composed of three parts: glass fiber epoxy resin drawing rod, silicone rubber umbrella skirt and metal fittings. The silicone rubber umbrella skirt adopts the whole injection and compression process, thus solving the key problem affecting the reliability of composite insulators -- the interface electrical breakdown.

The connection between the glass drawing rod and the metal fittings adopts the unique glue fitting technology, and adopts the most advanced pressing technology in China. It is equipped with the automatic sound wave flaw detection system with high strength, beautiful appearance, small volume and light weight. The metal fittings are galvanized to prevent corrosion and can be used interchangeable with ceramic insulators.

Production Process (Part)

 

FEATURES:

 

1. The silicone rubber housing of Composite Line Post Insulator were taken shape by whole injection. It has good hydrophobicity, hydrophobicity migration and soil resistance, as well as excellent electrical insulation properties and aging resistance, which could prevent effectively those accidents of pollution flashover so as to ensure the safe running of high voltage transmission lines. 
2. The modified ECR fiberglass reinforced epoxy resin rod is used as it has good resistance to high temperature, stess corrosion & 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 stength of insulators.
3. End fittings are crimped onto fiberglass rod with voice-operated displacement type crimper. The insulators with this crimping technique have high mechanical strength and small dispersion. Taking the most advanced automatic overall injection moulding technic and connection method of crimping for production and assembling, and the whole crimping procedure controlled by computer and the crimping result monitored by ultrasonic detector to assure each product is qualified.

Company Profile

Wuhan Line Power Transmission Equipment Co., Ltd. is mainly engaged in the research ,development,production and sales of high voltage transmission power composite insulator series products.The core technology comes from the scientific and research institutions such as Wuhan University (originally Wuhan University of Water and Electricity),Hubei Institute of Chemical and Industry and Wuhan High Pressure Research Institution and so on.

In order to adapt to the industry development demands,it was reformed in combination with national capital by the scientists and engineers who are in the field of composite insulator.Now it is restructured as a new modernized enterprise which integrates research ,production, marketing and sales. The company had formed a series of composite insulator mature products at the beginning of its establishment. These products have been widely used in power, railway and other industries for many years.The core team members of company technology, production and management have more than 20 years of working experience in the same industry. The excellent core team ensures the high starting point of the company in technology and products.

 

Our company with strong strength, reasonable price, good service and a number of enterprises to establish a long-term partnership.With high quality products and perfect after-sales service, we have won the consistent reputation of customers all over the country.We sincerely welcome customers from home and abroad to visit, investigate and discuss business cooperation.    

Product structure and advantages
Our company specializes in the production of composite insulators for transmission lines. The main structure is composed of rubber, epoxy glass fiber core and metal end fittings.
 

Compared with similar ceramic and glass insulators, silicone rubber insulators have the following advantages:

(1) Small size, light weight (1/7~1/10 times that of ceramic insulators with the same voltage), good elasticity of the shed, not easy to break, convenient transportation and installation, and economical.

(2) High mechanical strength. FRP rods have high tensile strength, which is 5-10 times that of ceramic materials. The cross-section of the core material is small, the product is small in size, light in weight, and high in tensile strength. It is easy to manufacture large-tonnage insulators above 300KN.

(3) High antifouling performance and good aging resistance. The silicone rubber injection molded shed has good hydrophobicity and mobility, which makes the insulator have high anti-pollution flashover voltage and good electrical corrosion resistance.

(4) Easy installation and maintenance, which can greatly reduce maintenance costs caused by power outages and manual labor intensity.

(5) The production process is simple and the delivery time is short.
