Standards

IEC 60433 – 2023
IEC 60383 – 2023
IEC 61325 – 1995

Puncture-proof (IEC 60383)

No need to stock replacements

40% lighter due to minimal metal parts – 3 per insulator

No encapsulated cement to cause hoop stress failure

Inspection every 2-3 years – 50-60% less maintenance

VS

Vulnerable to puncture, steep wave testing required

Replacement stock always necessary

15-30 metal components per string – heavy and prone to corrosion

Portland concrete used in assembly – at risk of material growth

Yearly inspection required

Case Studies

Demonstrated Resilience Against Heavy Saltwater Fog in the Netherlands

Challenge In the Netherlands, saltwater contamination poses a significant challenge for transmission line insulators. Much like the U.S. Pacific Northwest, the Dutch coastal climate is characterised by persistent fog and mist, often laden with high levels of salt particles from...
