11kv pin insulator specifications

1. What is a Pin Insulator
A Pin insulator is a component used to support or suspend a conductor and form electrical insulation between the tower and the conductor. Pin-type common ceramic insulators, porcelain parts and cast steel are used
Cement glue is glued together, and the surface of the porcelain pieces is coated with a glaze to improve the insulating properties of the insulators.
Second, what are the main uses of pin insulators?
The previous article has introduced what is a pin insulator, so what is the main purpose of the pin insulator?
Pin insulators are the earliest developed overhead insulators, and they are still widely used in transmission lines below 33 kV, and are mainly used in linear poles, towers or angles.
On the smaller corner towers, there are also tension towers for fixing wire jumpers.
Pin insulators can be divided into ordinary type (single umbrella), double umbrella type or triple umbrella type, and the choice of pin insulator model mainly depends on the line voltage of the dry application:
1. In the 11kV power system, we usually use ordinary pin insulators, that is, the entire pin insulator has only one umbrella-shaped canopy.
2. In High-voltage power systems such as 33 kV and 66 kV, ordinary pin-type insulators are difficult to perform the heavy task of high-voltage insulators. Because, the higher the voltage, the more
The thicker the insulating layer required by the road is to ensure that it has sufficient insulating properties during operation. In this case, the power system is more inclined to dry multi-umbrella pin insulation
Insulators, that is, multiple enterprise skirts are fixed together to form a complete insulator unit, while 33kV power systems generally use double enterprise type pin insulators, 66kV power one
Generally, three-enterprise type pin insulators are used.
