Power Line Insulator

Power Line Insulator

Power line insulators are one of the important components widely used in contact nets. The insulator materials produced by ZMS are usually made of high-quality porcelain or composite. Most commonly used types are Pin type insulators, Suspension type insulators, Strain insulators, Shackle insulators.

Kind of the Power Line Insulator Products

Strain insulators

Strain Type insulators

  • Strain insulator is an electrical insulator.
  • They are commonly used in overhead transmission lines and are designed to work under conditions of mechanical tension changes in order to withstand the tension of suspended wires or cables.
  • The typical strain insulator is made of glass, porcelain, or composite.
  • Under certain conditions, strained insulators can be used in series: a group of insulators are connected to each other through dedicated hardware.
  • In this way, the strained insulator can not only withstand greater physical tension, but also has higher and more effective insulation properties.
Pin type insulators

Pin Type insulator

  • Pin-type insulators are power line insulators developed earlier.
  • They are commonly used in power distribution systems with a maximum voltage level of 33kv.
  • Pin insulators are usually made of porcelain, but in some cases glass or plastic can also be used.
  • Since pin insulators are usually used in the open air, they are designed with canopies or petticoats.
  • This keeps its inner surface dry and non-conductive.
Suspension insulator

Suspension Type insulator

  • When the overhead line voltage level exceeds 33kv, the volume and weight of the pin insulator will become larger.
  • In this way, the pin insulator becomes very uneconomical. Therefore, we use suspension insulators to deal with voltage systems higher than 33KV.
  • Suspension insulators are composed of many porcelain plates, which are connected to each other by wire-shaped metal chains.
  • Each disc is designed for low voltage, such as 11kv. The sign of the disc depends on the operating voltage.
  • Suspended insulators are the first choice for high-voltage transmission lines.
Shackle insulator

Shackle Type insulators

  • Shackle-type insulators are commonly used on low-voltage and medium-voltage overhead transmission lines.
  • This insulator can work in two positions, horizontal or vertical.
  • The tapered holes of the shackle insulator can distribute the load more evenly and reduce the possibility of rupture in case of heavy load.
  • The raw materials used in this insulator are mostly porcelain.

The Advantages of Different Types of Overhead Power Line Insulators

Eletrical insulator is a very important insulation control in overhead transmission lines. It can support the wire and prevent the current from returning to the ground. Electrical Insulators ensure that various electromechanical stresses remain unchanged when environmental and electrical load conditions change, thereby protecting the service life of the entire line. Because the overhead power line is always supported on the insulator installed on its support pole/tower. It is very important to choose the correct insulator, so as to ensure the successful operation of the power line. Therefore, overhead transmission line insulators should have the following characteristics:
