high resistance neutral grounding resistor
ZX15 series resistors are open type, suitable for AC 50Hz, voltage up to 660V and DC voltage to 440V or less for start, speed, brake, discharge and other purposes. Its capacity is 4.6 kW, which is made up of a spiral tubular resistor element wound from an iron-chromium-aluminum alloy strip. Can replace the ZX1 series resistor application. It has the advantages of shockproof and non-breakable. The altitude does not exceed 2000 meters; the ambient temperature does not exceed +40 ° C and not lower than -25 ° C, the average temperature within 24 h does not exceed +35 ° C. When the temperature is +20 ° C to -5 ° C, the relative humidity of the air is not more than 85%. There are no gases and conductive dust in the surrounding medium that can corrode metals and damage insulation and explosion hazard; there must be areas where rain and snow protection equipment is not filled with water vapor; in areas where there is no severe vibration or bumps.
