Voltage Outdoor High Quality 12kv Polymer Expulsion Fuse Cutout
Overview:
Drop out fuses and load-drop fuses are outdoor high voltage protection appliances. It is installed on the high voltage side of the distribution transformer or on the branch line of the distribution line. used as a short circuit of the transformer and the line, overload protection and split load current.
Advantage:
1. Small size,Light weight,resistance to impact,no collision damage during transportation,flexible installation,suitable for use in the switch cabin.
2. Special structure,the overall compression molding,no air gap,good sealing performance,moisture-proof and explosion-proof 3. Large creepage distance,good hydrophobicity,strong stain resistance,stable performance and reduce operation maintenance. 4. Unique formula of zinc oxide varistor, small leakage current,slow aging,long service life.
5. With DC reference voltage,rectangular flow capacity and high current and large current withstand capacity are higher than standard requirement.
