Outdoor solid rod porcelain post insulator

Porcelain Station Post Insulators are essential to the safe and stable distribution of electricity generated at power plants. 

Overview

Outdoor solid rod porcelain post insulators are used in power frequency AC voltage 10-500kV outdoor power stations, substation distribution devices and electrical equipment for insulation and support of live parts.

The applicable environment of insulators is - 40 ~ + 40, and some products can be used in areas with an altitude of 4000m. The products are divided into two categories: ordinary shape and pollution resistance. The pollution resistance can be applied to medium, heavy and extra heavy pollution areas.

Porcelain Post Insulators are essential to the safe and stable distribution of electricity generated at power plants. The station post (SP) insulators found in power handling equipment at power plants and substations support electric cables and other equipment, isolating them from the ground.

Characteristic:

1. The insulator has high mechanical strength, low dispersion and safe and reliable operation.

2. The insulator has good low-temperature mechanical performance.

3. Excellent pollution resistance.

4. High earthquake resistance level.

5. Low radio interference.
