Notice for purchase 1. system rated voltage 2.short-time withstand current; 3. normal resistance; 4. with current transformer or not; transformation

Operation Conditions 1. Mostly applied outdoor in system of 50Hz and 60Hz 2. Max Altitude is 3500m. Because of high altitude and bad thermal discharging in plateau, please indicate in order if in this situation. 3. Ambient Temp is between -20C+70C and relative humidity does not excess 95%. 4. Wind pressure does not excess 700Mpa (equivalent to 34m/s) 5. Earthquake intensity is less than 8 degree. 6. Thickness of ice coverage is less than 10mm 7. Air dusty grade is not higher than IV grade 8. No corrosive or explosive gas and conductive dust around installation site. 9. As the resistor is a heat generating component, it should be installed in place with some space left around, and be away from heat source.Type System voltage kV Rated currentA Short timeS Rated voltage5% Insulation resistance voltage Kv8/20SLightning surf 1min FrequencyMRD-BJ-6/36.4 6.3 100 10 36.4 60 32MRD-BJ-6/18.2 6.3 200 10 18.2 60 32MRD-BJ-6/9.09 6.3 400 10 9.09 60 32MRD-BJ-6/6.06 6.3 600 10 6.06 60 32MRD-BJ-10/15.16 10.5 400 10 15.16 75 42MRD-BJ-10/10.10 10.5 600 10 10.10 75 42MRD-BJ-10/7.57 10.5 800 10 7.57 75 42MRD-BJ-10/6.06 10.5 1000 10 6.06 75 42MRD-BJ-35/20.20 35 1000 10 20.20 185 95MRD-BJ-35/10.10 35 2000 10 10.10 185 95

Technicial Parameters MRD series resistor is safe and reliable with high capacity, corrosion-resistence, non-induction, non-contact resistance and resistance value stablity with tolerance of 2.5% of total value, long lifetime, small volum with high power, replacing old type of resistance and widely used in metallury, chemical, mining industry, building, ports, power stations and etc. Resistor Structure Resistacne components is made from stainless steel processed as net shape, M shape, Spiral or other kinds of shape. With mounting holes in four corners, there are concave-convex porcelain settings between resistance componets for fixing, so are isolated porcelain pieces for the purpose of insulation preventing short-circuit. The are three outlines of open type, proof type and cabinet type for option. Intergrated set of equipment could be produced as per customerss parameters.
