Composite insulators can effectively use narrow corridors to open voltage and transmit electricity, and are suitable for technical transformation of urban network. They can reduce the height of poles and towers and save a lot of manpower, material resources and financial resources. Due to the high bending strength of composite material insulators, it can prevent the cascading fracture accidents that are prone to porcelain cross arm, and it is an irreplaceable product for porcelain cross arm. In addition, the composite insulator is small in size, light in weight, shockproof and impact resistant, and does not require manual cleaning, which provides a guarantee for safe operation.

What are the Functions of Electricity Insulators？
A lot of disk-shaped insulators are hung on one end of the high-voltage wire connection tower to increase the creepage distance, usually made of glass, ceramic or composite materials, called electricity insulators.
In order to prevent dust and other pollution from adhering to the surface of the insulator, a path is formed to be broken down by the voltage across the insulator, that is creepage. Therefore, increase the surface distance, that is the creeping distance, and the distance along the insulating surface that is the leakage distance is called the creeping distance. Climbing distance = surface distance / the highest voltage of the system. Depending on the degree of pollution, a crawl distance of 31 mm/kV is generally used in heavily polluted areas.
What are the Advantages of Cold Shrink Cable Termination?
The Difference Between Cold Shrink Termination and Heat Shrink Termination:
1. The difference between the ground wire connection methods: Cold-shrinkable cable accessories use constant force springs. The heat shrinkable cable accessories need to be soldered when using a ground wire.
2. The difference of the shrinkage method: The plastic support strip of the core part of the cold-shrinkable cable accessory shrinks naturally. The heat-shrinkable cable accessory needs to be heated by fire to shrink the low-voltage cable termination.
