ZX15 series resistor for the open type, suitable for AC 50HZ, voltage up to 660V and DC voltage to 440V follows the following circuit, made for starting, speed, braking, discharge and other purposes. Its capacity 4.6KW, is made of iron-chromium alloy tape wound into a spiral tubular resistive element fitted into. Can replace the ZX1 series resistor applications. With shock, not broken and so on. ZX15 series resistor using iron-chromium alloy resistance material, it is a high electric resistance alloy, with high temperature, long life, than resistance, high surface load, temperature coefficient of resistance is small, the proportion of small series of advantages. Scope height of not more than 2500 meters above sea level; ambient temperature does not exceed +40 ℃ and no less than -25 ℃, the average temperature within 24h does not exceed +35 ℃; when -5 ℃ to +20 ℃ relative humidity of the air greater than 85%; surrounding medium does not enough to corrode metal and damage the insulation and potentially explosive gases and conductive dust; shall be protected against rain and snow equipment and is not filled with water vapor regions; in the absence of severe vibration or Britain lame region.
