StandardsIEC 61109/ANSITypeFXBW-500/100-A to FXBW-500/400-C
MaterialComposite/polymericTestsAll type tested and design tested


1, 500kV Composite Insulators used for High lands overhead transmission lines are welled designed to suit to the special environment in high lands like very strong UV and wind.

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 utilities.

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 test.

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 voltage.

6, All the 500kV suspension or tension insulators are designed with two corona rings


1, 500kV overhead transmission power lines in high lands.

2, 500kV substations high lands.

Competitive Advantage:

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 performance.
