Description:
Insulators are a special insulation control that can play an
important role in overhead transmission lines. In the early years,
insulators were mostly used for telegraph poles, and slowly
developed a lot of disk-shaped insulators hung on one end of the
high-voltage wire connection tower. It is used to increase the
creepage distance. It is usually made of glass or ceramic and is
called an insulator. Insulators should not fail due to various
electromechanical stresses caused by changes in the environment and
electrical load conditions, otherwise the insulators will not have
a significant effect, which will damage the use and operating life
of the entire line.
Pin insulator is a component used to support or suspend a wire and
form an electrical insulation between the tower and the wire. The
ceramic parts of the pin-type ordinary ceramic insulator and the
cast steel are glued together with cement glue, and the surface of
the porcelain part is coated with a layer of glaze to improve the
insulation performance of the insulator.
Ceramic porcelain pin insulator is used between the discharge
electrode framework and ESP casing functioning as connecting and
high-voltage insulating. By its own structure it is divided into
two types: pure ceramic insulator and combined insulator.
