Description:

1, 25kV composite railway insulators are widely used in electrified railways.

2, Dead end fittings are up to the requirements from the clients, usually we use ball, socket, tongue, clevis for tension 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.

Applications:

1, Used in electrified railways

Advantage No. One

Technical comparison
Mechanical failure	Reduction in mechanical strength and separation during to pings getting eroded	Just with single piece, so no such kind of problem
Resistance to flashover and punctures	Low	High
Anti tracking and erosion resistance	Very low- poor tracking resistance	Excellent tracking resistance avoids erosion or tracking of the housing material
Dielectric strength	Lower than polymer	Excellent insulation performance
Contamination and pollution	Highly effected	Not effected and has much longer life
Hydrophobicity	No hydrophobicity, ceramic surface forms water films on the surface making easy path leading to more flashover	Very excellent hydrophobicity
