EHV AC Composite Polymer Insulator 330 kV For Electricity Transmission Lines

EHV AC Composite Polymer Insulator 330 kV For Electricity Transmission Lines

Specifications:

Dimensions and Characteristics of 330KV AC composite polymer insulator

Description:

1, 330KV AC suspension tension 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 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 330KV AC suspension or tension insulators are designed with two corona rings

Applications:

1, 330KV AC EHV overhead transmission power lines.

2, 330KV AC EHV substations

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 a
