Technically speaking, "medium voltage" fuses are those intended for the voltage range from 2,400 to 38,000 VAC." Siemens says, "Medium voltage metal-clad switchgear (above 1000Vac up to 38kVac)" This last one covers most of the definitions. Thus, probably a good working definition of medium voltage is from

Sector description The electricity industry makes use of equipment insulated with SF 6.Most SF 6 is used in circuit breakers, although it can also be used in related equipment such as switches, disconnectors, current
Get Price2008-1-22Standardization of the Ultra-High Voltage level ( 800 kV a.c.) The first step is the definition of rated voltage(s) and insulation levels by TC28 and TC8. Concerning high-voltage switchgear, IEC SC17A asked CIGRE SC A3 to set up a new working group to study technical requirements for UHV equipment.
Get Price1997-7-26Most medium voltage switchgear contains less than 5kg of SF6, so doesn’t require leak checks. Most large high-voltage swithgear equipment is fitted with a pressure or density monitoring device, so doesn’t require leak checks. Operator and service companies share responsibility for stopping SF6 leaks. This

Get PriceFactories that require medium or high voltage supply from the electric utility can have a dedicated sub-station. These substations step down voltages levels and distribute to buildings throughout the property. However, not all factories require high or medium voltages. Some require low voltages
