Description:

1, 400kV composite high tension insulators are widely used in 400kV 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 tension insulators with forged 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 400kV composite high tension insulators are with two corona rings.

Applications:

1, 400kV EHV overhead transmission power lines.

2, 400kV EHV substations

Model Number:
FXBW-400 kV /160kN to FXBW-400 kV /210kN
The advantages of polymer/composite insulators over ceramic/porcelain insulators
General comparison
Factor Ceramic/porcelain insulators Polymer/composite insulators
Weight

Heavy weight- For example

400kV - about 140kgs

90% lighter than them but with same mechanical strength

400kV -- Around 15kgs

Fragility Highly fragility to shock and vibration No fragility to shock and vibration
Packing and transportation Risky and very costly Easy and economical
Installation Risky expensive and more labor required Very easy and economical
Handling Difficult Easy
Maintenance cost Very expensive Low
Vandalism More susceptible Highly resistant
Breakages and secondary damage Highly fragile- 10-15% breakages are reported during transportation storage and installation Flexible and therefore highly resistant to breakages
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
