HY5WZ-17kv/26kv/32kv/34kv Shielding Type Rear-Connection Arrester
Product Introduction
*l Lightning arrester provide protection for electrical apparatus from lightning and over voltage.
* Lightning arrester adopts special anti-explosion device.
* The arrester can keep in good operation in the condition of long time aging or thunder lightning strike.
* Protect the arrest from explosion or permanent earthing fault
* Guarantee the grid running safely
Note:
HY5WZ-17/45(50) applies to Q(H)T-15kv/630A
HY5WZ-17/45(50) only applies to non-shielded front, rear connected to arresters.
HY5WZ-32/85(34/90) only applies to 24kv rear arrester
