High-voltage insulator FXBW-750kV/400kN

compositepolymersilicone rubber

1, 750kV(765kV) composite high tension insulators are widely used in 750kV(765kV) 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 suspension insulators with forged steel or cast 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 750kV(765kV) composite high tension insulators are designed with two corona rings 1, 750kV(765kV) EHV overhead transmission power lines. 2, 750kV(765kV) EHV substations.
