A. Application
This equipment is applied extensively in chemical, paper mill, smelter, carbon etc. which provides DC power for electrolysis equipment for production of Caustic Soda,Sodium Chloride, Chloride Dioxide, Aluminum, Zinc, Magnesium, Copper, Lead, Sodium, Cobalt, Manganese and DC heating power for production of graphite and carborundum etc.
B. Main Characteristics
1.Integrated design to integrate the rectifier section, control section, power distribution section, DC switch and DM water cooler etc. save installation space and is convenient for installation and commissioning at the site.
2.Complete sealed design, the protection class IP 55, and prevent conductive dust and corrosive gas to improve the safety and extend the lifespan of the rectifier equipments.
3.Complete aluminum cubicle, prevent the local overheating effectively caused by eddy current by non conductivity of aluminum, extend the rectifier lifespan by excellent corrosion resistance.
4.Avoid the external temp. affection by the air cooling and thermal insulation design; maintain constant inner cubicle temp, and outdoor installation type also save the workshop construction cost.
5.Complete protection measures for monitoring the air humidity, air temperature, water temperature, water pressure, water leakage, air flow, element temperature etc. No need for inspector in the site.
