Description:

?

1, 220kV 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 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 these 220kV suspension or tension insulators are designed with one corona rings

?

?

Applications:

?

1, 220kV HV overhead transmission power lines in high land areas

?

2, 220kV HV substations in high land areas

?

?

Advantages:

This kind of products have the following characters and advantages:

?

1) The silicon rubber rain shed, designed according to the aerodynamics principle, use the whole-moulding method, to make sure the validity of total creepage distance under every climate and nasty conditions, as well as improved the pollution discharge of the insulators.

2) The fiber rod uses the ECR high-temperature and acid-proof material.

3) The end fitting connection adopts the zinc cover protection, supersonic monitor and coaxial constant compression controlled by computer, finished with good appearance and high quality.

?

Advantages:

?

1) Composite insulator with competitive price and good quality.

2) Hop dip galvanized cast SAE1045 steel for metal fittings.

3) Silicone rubber for sheds
