Description:
1, 500kV interface spacer is always used in very strong wind area 500kV transmission power lines to protect the conductors from connecting with each other.
2, Dead end fittings are up to the requirements from the clients, usually we use tongue type, clevis tyep or big ball types. The dimensions and coupling size can be exactly according to the specification requirements from the utilities.
3, The silicon rubber color of theinterface spacer is also up to the requirements from the clients and all the silicon rubber materials passed 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 interface spacers 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, 500kV overhead transmission power lines.
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 and ceramic insulators.
3, Excellent hydrophobicity characteristics can help to void flashover and guarantee the insulators with very good electric performance.
