Description:

?

1, 35kV(36kV,40.5kV)Polymer/composite Line Post Insulators are widely used in power transmission lines and substations

?

2, Dead end fittings are up to the requirements from the clients, usually we use different flanges for post 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 IEC61952, maximum RIV is 100μV when tested at 1MHz and10% over nominal line ground voltage for indicated system voltage.

?

6, All the Line Post Insulators with the voltage lower than 110kV are not supposed to use corona ring.

? ? All the Line Post Insulators with the voltage equal to or higher than 110kV but lower than 220kV are supposed to use one corona ring at the line end.

? ? All the Line Post Insulators with the voltage equal to or higher than 220kV are supposed to use two corona rings at both sides.

?

?

Applications:

?

1, Usually used in 35kV substations

?

2, Usually used in 35kV Electric Power Lines

?

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
