HY5WZ-51/134 40.5 kV HY5W Zinc Oxide Lightning Arrester with Switchgear
Collision resistant, flexible installationSpecial structure, no gap, good sealing, corrosion resistance Pollution resistance, stable performance . Unique formula zinc oxide resistor, high capacity, low leakage .
The load switch adopts the pressure gas internal blowing structure, the arc extinguishing ability is strong, and does not affect the interphase and ground insulation, both the dynamic and static contacts have the arc contact, greatly increased the number of breakdowns.
The fuse and the load switch room form the transformer protection circuit. The high voltage flow limiting fuse is installed in the insulated shell of epoxy pouring. After the fuse is broken, the firing pin is ejected and the load switch is divided.
