Toughended glass insulators |
|
|
Our toughened glass suspension insulators are very reliable, high quality products suitable for use with over headlines in high and medium voltage networks. They are available as standard glass insulators with mechanical failing loads up to 300kN and creepage distances up to 485mm and as fog type glass insulators with mechanical failing loads up to 210kN and creepage distances up to 550mm.
They are made out of toughened glass which makes the insulation part. The ball and socket connecting parts are made out of cast iron.
Our toughened glass insulators comply to IEC 60120, IEC 383 and IEC 305:1995
