ZX10 series resistor for the open type, suitable for AC 50HZ, voltage 550V and 440V DC the following circuit, made for starting, speed, braking, discharge and other purposes. This series resistor include ZX10 ZX10 style with the use of standard non-standard type. ZX10-type resistor is made by the iron-chromium alloy with screw-type tubular resistive element (ZD2 type) assembled. Fe-Cr alloy resistive material is high resistance electric heating alloy, with high temperature, long life, than resistance, high load, temperature coefficient of resistance is small, the proportion of small, shockproof, easy to break and so on. Scope altitude does not exceed 2500m; ambient temperature does not exceed +40 ℃ and no less than -30 ℃ +20 ℃ ± 5 ℃ when the air relative humidity less than 85% of the surrounding medium does not enough to corrode metal and damage the insulation and explosive gases and conductive dust; shall be protected against rain and snow equipment and is not filled with water vapor regions; 6, in the absence of severe vibration or strong turbulence region. Model significance appearance and installation dimension three following resistance when installed, can be directly stacked with each other. 4-6 sets resistor installation must be supported with a bracket mounted, not to reduce its capacity, both up and down There shall be not less than 80 mm spacing. If more than six, the six resistors in each group consisting of the group should be left between the vertical interval of 380 mm or more.
