Hirect make cathodic protection transformer rectifier unit (trus) are of automatic and manual controlled for cathodic protection of buried pipelines across the country, storage tanks at terminals refineries and other buried structures.Application : trus are used to prevent submerged (soil or water ) metalic structures from corrosion. All submerged pipelines (oil, water etc.), concrete structure of bridges buildings sea ports etc can be protected from corrosion by doing cp.Trus superimposes dc currents in to the steel structure to be protected in opposite direction to the galvanic corrosion currents & protects the structure from corrosion.To obtain the optimum level of protection under varying conditions, it is necessary to vary the impressed current continuously so as to maintain a constant level of protective potential at the structure. This continuous monitoring and control can be achieved by providing an automatic control for the cathodic protection system.Hirect offers several types of tru which are designed, manufactured and tested under strict quality assurance system to achieve highest quality standards. Features and benefits:type of unitsnatural air cooled , oil cooled , indoor or outdoor type , self standing operational climatic conditiontrus are designed to work under severe environmental conditions with maximum ambient temperature of 50 c and humidity of 95 % (non condensing).enclosure confirming to class ip 55 degree of protectiontransformerall the transformers used in trus are designed to give high efficiency giving low loss.the coils are wound with high conductivity, annealed , insulated electrolytic copper and core material is high permeability , low loss crgocrngo.the insulation material used is of high standard class f .Rectifierrectifiers are based on internal quality standards and our own make diodes silicon controlled rectifiers.
