22 kV Polymer Post Insulator – Tough, Lightweight & High Performance 

The 22 kV polymer post insulator is a contemporary technology that advances the capabilities of medium voltage electrical systems to an even more modern level, with the potential for less maintenance and higher reliability compared with traditional ceramic or glass insulators. The polymer post insulator is used to support and insulate conductors in the switchgear, substation or distribution networks, and is an important part of the safe and efficient delivery of electrical power. The polymer post insulator is constructed from fiberglass core rods and has an outer covering of high-grade silicone rubber which makes this insulator suitable to handle extreme climates, pollution or installation conditions where weight reduction is required and performance must not be compromised. 

✓ Features & Benefits 

– Voltage Rating: Designed specifically for 22kV medium voltage deployments

– High Creepage Distance: Guarantees reliable insulation in dusty or high-humidity environments

– UV & Weather Resistant: Functions in extreme climate variations – from blazing hot desert to torrentially rainy coasts

– Low Maintenance: Hydrophobic surface that repels moisture and contaminants 

– Lightweight: Even a breakeven 22 kV polymer post insulator can be as much as 60% lighter than porcelain insulators, vastly improving the transport situations for the devices as well as their installation situation
