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
