Description:
 
1, 220kV Cross-arm Insulator 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 Cross-arm Insulators with the voltage lower than 110kV are not supposed to use corona ring.
    All the Cross-arm 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 Cross-arm Insulators with the voltage equal to or higher than 220kV are supposed to use two corona rings at both sides.
 
 
 
Applications:
1, All the 220kV substations
2, All the 220kV Electric 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.
