33kv 36kv 200A Pole Mounted Mv Polymeric Drop out Fuse Cutout

DescriptionDrop-out fused cut out and load Switching fuse cutout are of outdoor used high voltage protective device.To be connected with incoming feeder of distribution line it mainly protect transformer or lines from shortcircuit and overload, and on/off loading current.Standard: IEC 60282-2  ComponentsDrop-out fused cut out is composed of insulator supports and fuse tube. Static contacts is fixed on insulator support and moving contact is installed on two ends of fuse tube. Fuse tube is composed of:1. Inside arc estinguishing tube2. Outer phenolic compound paper tube or epoxy glass tubeLoad switching fuse cutout provides enforced elastic auxiliary contacts and arc-extinguishing enclosure for switching on/off loading current.  Operating Principle1. When working normally, fuse link tightened the fuse tube to be close position.2. If system occur faults, big fault current melts fuse immediately and take place electric arc, which makesarc extinguishing tube being heated and explode a lot of gases. This will produce high pressure and blow off the arc along with tube.3. After fuselink melt moving contact has no tightened strength, mechanism is locked and fuse tube dropout.4. Cutout now is in open position. Operator shall use insulating Link Rod to pull the moving contact.Main ParameterTypeRated Voltage (kV)Rated Current (A)Breaking Current (A)Impulse Voltage Bil (BIL)Power Frequency withstand voltageLeakage Distance (mm)Weight (kg)Dimension (cm)HRW-1212100630011040250640X36X11.5HRW-121220010000110402506TypeRated Voltage (kV)Rated Current (A)Breaking Current (A)Impulse Voltage Bil (BIL)Power Frequency withstand voltageLeakage Distance (mm)Weight (kg)Dimension (cm)HRW-333310010000170708501290X40X17HRW-3333200125001707085012 /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
