| Serye | RNL-40.5 |
An ni nga 40.5kV switch nag-integrate og load switching ug fuse protection sa usa ka SF6 gas-insulated design, gihimo para sa medium-to-high voltage power distribution systems. Ang SF6 insulation nag-siguro og excellent dielectric performance, compact size, ug resistance kontra sa harsh environmental factors sama sa dust, humidity, ug extreme temperatures.
Ang RNL-40.5 isolation switch nagsatisfy sa requirements sa GB3804-2004 "3.6kV~40.5kVhigh voltage AC load switch",“GB16926-1997 AC high voltage load switch, one fusecombination appliance".
Main circuit: 630A-20kA (4S) ug 25kA (3S); mechanical life: 5000 times; groundingcircuit: 20kA (2S); mechanical life: 2000 times.
Considerations for the use of environmental conditions
Ang altitude dili mogasangon sa 2000m, ang shattering dili mogasangon sa 8 degrees
Ang environmental temperature sa product -40 degrees ~+140 DEG C, ang relativehumidity dili mogasangon sa 90% kada adlaw, ug ang average dili mogasangon sa 90% kada bulan;
Ang installation site sa frequent ug violent shock, water vapor, chemical corrosiondeposition, salt fog, dust, dirt ug fire, nga obvious na makaapekto sa performance sa mechanism, dili suited sa installation sa explosive dangerous installations.
