Product Description

Product Description

Composite 25kV polymer disc insulator is composed of glass silicone rubber umbrella skirt, glass fiber epoxy resin solid rod and metal fittings.The silicone rubber canopy skirt adopts the whole injection and compression technology, and the glass fiber solid rod is connected with the metal fittings in the compression and connection way, thus solving the key problem affecting the reliability of  composite insulators -- the interface electrical breakdown.The company adopts the most advanced pressing technology in China, equipped with automatic sound wave damage control and detection system, small size, high strength, beautiful appearance, light weight.It can be used interchangeably with porcelain insulators. The structure of this product is reliable, without damaging the mandrel, and it can give full play to its mechanical strength.

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.
 
 

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.
