Composite tension insulators are essential components used in electrical power transmission systems. They are designed to provide reliable support for power lines while also insulating them from the surrounding environment. The 66kV composite tension insulator is a high-quality product that can withstand high voltage and harsh environmental conditions.
This insulator is made from a composite material that is lightweight and resistant to environmental degradation, such as UV radiation and corrosion. Its unique design ensures it can handle heavy loads and extreme weather conditions without compromising performance.
The 25kV composite tension insulator is easy to install and maintain. Its simple design allows for quick and easy attachment to power lines, reducing installation time and costs. Maintenance is also minimal, as the insulator requires no special cleaning or upkeep beyond regular inspections.

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.
