Cross Arm Porcelain Insulators

Porcelain cross arm insulator is a kind of conical or cylindrical insulator that plays the role of cross-arm support and insulation at the same time. Porcelain cross-arm insulators not only have the same function of fixing wires and grounding insulation as ordinary line insulators but also all or part of porcelain cross-arm insulators can replace iron cross-arms or wooden cross-arms. Insulators used for overhead lines are called line insulators, and porcelain cross-arm insulators are a type of line insulator. In order to reduce line corridors in urban areas, it is often seen that overhead lines often use cross-arm insulators. /

The materials of cross-arm insulators are usually divided into two categories: electric porcelain and polymer materials, and there are also distinctions between porcelain cross-arm insulators and polymer cross-arm insulators. Porcelain cross-arm insulators have significant advantages. For example, porcelain cross-arm insulators have high insulation levels, low accident rates, safe and reliable operation, and can save a lot of steel and reduce costs. Porcelain cross-arm insulators have a simple structure, the structure is an ordinary shed without grooves and is very convenient to install. In practical applications, porcelain cross-arm insulators can be used not only on 10~35kV lines but also on 110 and 220kV lines in some areas. When the line voltage level is higher, the mechanical strength of the cross-arm insulator is also required to be higher.
