1, 15kV tension suspension insulators are widely used in overhead
transmission lines and substations
2, Dead end fittings are up to the requirements from the clients,
usually we use ball, socket, tongue, clevis for tension insulators
with forged steel or cast 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 15kV tension suspension insulators are without corona
1, 15kV overhead transmission power lines.
2, 15kV substations
3, 15kV distribution lines
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
