Pin Type Glass Insulator PR3
VHT 22T Pin Glass Insulator – Engineered for Reliability in Modern Power Distribution
When it comes to overhead power distribution systems, performance, safety, and longevity are non-negotiable. That's why YIWU SASUN ELECTRICAL CO., LTD. proudly presents the VHT 22T Pin Glass Insulator—a high-strength, IEC-certified solution designed to meet the rigorous demands of today's electrical infrastructure across diverse global environments.
Key technical specifications of the VHT 22T include
● Creepage Distance: 415 mm (tested up to 425 mm), ensuring superior insulation performance even in polluted, humid, or coastal conditions.
● Mechanical Breaking Load: 14 kN, providing robust mechanical support for conductors under heavy loads, wind, or ice accumulation.
● Height: 168.5 mm – optimized for standard pole configurations and efficient line design.
● Pin Type: TR25 threaded steel pin for secure, standardized mounting and compatibility with common hardware.
● Compliance: Fully certified to IEC 60383-1, the international standard for insulator performance, safety, and reliability.
These features make the VHT 22T not just a component—but a critical safeguard for grid stability.
Ideal for Diverse Applications Worldwide
The VHT 22T Pin Glass Insulator is engineered for medium-voltage overhead distribution lines, typically used in 11 kV to 33 kV systems. Its robust design and material properties make it especially suitable for:
● Urban and rural power networks requiring long-term reliability with minimal maintenance
● Industrial zones and mining operations where pollution and mechanical stress challenge insulation integrity
● Coastal regions exposed to salt fog, where high creepage distance prevents flashovers
● Arid or dusty climates where contamination buildup can compromise electrical performance
● Infrastructure projects in emerging markets, including Africa, Oceania, and Southeast Asia
● Backed by successful deployments in New Zealand, South Africa, Cameroon, and beyond, the VHT 22T has proven its adaptability to extreme temperatures, high humidity, dust storms, and corrosive atmospheres.
