We offer cathodic protection equipment. Natural air cooled or oil cooled indoor or outdoor, wall mounted or base mounted. Ac operated, dc operated, ac/dc operated and solar power operated. Units are designed to work under severe environmental conditions with temperature range up to 55 c ambient & protection class upto ip55 / ip56 & ip65. All transformers are designed to give low losses and high efficiencies. The core material is high grade, high permeability, low loss crgo silicon steel. The coils are wound with high conductivity, annealed, insulated electrolytic copper conductors. The insulation material used is of high standard to suit class f grade. The transformers manufactured and tested as per iec76, bs 171 standards. Rectifiers are based on international quality diodes and silicon controlled rectifiers. Rectifier circuits have different circuit topology based on customer need, specification and efficiency. Single phase bridge is used up to 5kw output and above that three phase bridge or hexa-phase with inter phase transformer scheme is used for higher efficiency. Rectifiers are designed and tested as per iec 146 standards. Generally following protection is provided: - fast acting electronic over current limit & short circuit protection for output. - mcb and / or hrc fuses in ac input, dc output for short circuit protection, overload protection & on/off operation. - glass cartridge fuses in the live line of all lamps & in the auxiliary power lines to control circuit.
