Ansi Lin Post Insulators For High Voltage China

Ansi Lin Post Insulators For High Voltage

ANSI Line Post Insulators for High Voltage are a type of electrical insulator that is widely used in power plants, transmission substations, distribution substations, and high voltage power equipment up to 1100kV. These insulators are used in applications for both insulating and structural support of live components.

Here are some key features of these insulators:

1.They have a high mechanical strength design, including cantilever, torsion, compression, and expansion strength.

2.They are designed to be anti-ageing, anti-UV, and anti-sandstorm.

3.They have a smooth surface with high hardness and exceptional anti-pollution performance.

4.They exhibit minimal displacement under load.
