High Voltage Outdoor 24kv 27kv Load Break Polymer Drop-Out Fuse Cut Out
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.
The drop fuse is composed of two parts:
An insulating bracket and a fuse tube. The static contact is installed at two ends of the insulating bracket, the movable contact is installed at both ends of the fuse tube, and the fuse tube is composed of an inner arc extinguishing tube and an outer layer.
It consists of a phenolic paper tube or an epoxy glass tube. The load drop fuse enhances the elastic auxiliary contact and the arc extinguishing cover to divide and combine the 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.
