Details of 25 kV composite electric railway insulator
Rated mechanical bending load(KN)
Min nominal creepage distance(mm)
1min power frequency wet withstand voltage (kv)
Full wave lightning impulse withstand voltage(peak value)
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. 2.All our insulators were type tested and design tested in accordance with IEC61109, maximum RIV is 100V when tested at 1MHz and10% over nominal line ground voltage for indicated system voltage.
