69 Kv Post Insulator
Several different grades of packaging can be offered for 69 kv post insulator, it's depending on the mode of transport and the expected storage conditions.
1.Technical data of 69 kv post insulator
Rated mechanical bending load
Min nominal creepage distance
1min power frequency wet withstand voltage (kV)
Full wave lightning impulse withstand voltage peak value (kV)
2.69 kv post insulator advantage：
69 kv post insulator end fittings are crimped onto fiberglass rod with voice-operated displacement type crimper. The insulators with this crimping technique have high mechanical strength and small dispersion. Taking the most advanced automatic overall injection moulding technic and connection method of crimping for production and assembling, and the whole crimping procedure controlled by computer and the crimping result monitored by ultrasonic detector to assure each product is qualified.
