1, 1000kV composite high tension insulators are widely used in 1000kV overhead transmission lines and
2, Dead end fittings are up to the requirements from the clients,
usually we use ball, socket, tongue, clevis for suspension
insulators with forged steel. The dimensions and coupling size can
be exactly according to the specification requirements from the
3, The silicon rubber color of the insulators are also up to the
requirements from the clients and all the silicon rubber materials
past 5000 hours aging test silicon content test and hydrophobicity
4, ECR core rods are used in all the insulators, so we can
guarantee a very good mechanical strength and anti-acid pollution
performance for the insulators.
5, All our insulators were type tested and design tested in
accordance with IEC61109, maximum RIV is 100µV when tested at 1MHz
and10% over nominal line ground voltage for indicated system
6, All the 1000kV composite high tension insulators are with two corona rings.
1, 1000kV EHV overhead transmission power lines.
2, 1000kV EHV substations
1, Very good anti-pollution performance, no need to wash the
insulators after the installation in lines.
2, Very convenient installation because of its light weight and one
whole piece compared with glass insulators and ceramic insulators.
3, Excellent hydrophobicity characteristics can help to void
flashover and guarantee the insulators with very good electric
4, Our composite insulators designs offer lighter weight, less
breakage, improved seismic performance, high hydrophobicity and
withstanding contaminated condition and more flexibility in design
than ceramic insulators. These features often translate into lower
installation cost, greater durability and more aesthetically
pleasing line design.
