ZX9 series resistors for AC 50HZ voltage to 660V or 440V DC voltage to the circuit, mainly for motor starting, speed and production use. Resistor for the open type, the rated thermal power of 4.6KW. ZX9 series resistor series by various specifications were 40,80,96 resistance element assembled, for the Fe-Cr alloy resistive element with rolling into a wave shape, structure its width divided into large, medium and small, large punched in the film and for installation by the end, a small piece size is directly connected to the ends of each resistive coupling element are pressed with the fastening nut, to ensure good contact resistance. Resistors must be installed so that the vertical position of the resistive element placement. Scope height of not more than 2500 meters above sea level; ambient temperature does not exceed attack +40 ℃ and no less than -30 ℃; -5 ℃ to +20 ℃ when the air relative humidity less 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.
