Composite Post Insulator is suitable for power facilities. It has good hydrophobicity, aging resistance, tracking and electrical erosion resistance, also it has high bending resistance, torsion resistance, impulse resistance, Shockproof and brittle performance, light weight, convenient installation.If the mounting dimensions in the top and bottom is the same as the corresponding porcelain post insulator, then it can be interchangeable.
1.Insulating materials: Voltage-resistant insulating materials are usually used, such as ceramics or composite materials. These materials can effectively prevent the flow of electricity to the tower or support and ensure the normal operation of the line.
2.Mechanical strength: Insulators need to have sufficient mechanical strength to support the conductors on power lines and cope with the effects of natural environments such as external wind loads and ice loads.
3.Anti-fouling performance: 10kV insulators usually have good anti-fouling properties and can resist the impact of pollutants in the atmosphere on the surface of the insulator and maintain stable insulation performance.
4.Convenience of installation: Product design should take into account the convenience of installation to improve construction efficiency.
