Transformer

LS CAST RESIN Transformers will not emit oil or toxic gases into the atmosphere. Therefore, they do not pollute the environment and are strongly recommended as a replacement for askarel (PCB) -filled transformers. The complete casting of coils under vacuum prevent the penetration of moisture into the winding. Therefore, it is suitable for both storage and operating in harsh environment and is capable of being switched on immediately after such storage without pre-drying. There is no possibility of partial discharge in LS CAST RESIN Transformers. Whole core & coil is tested to guarantee the life expectancy of the insulation system. LS CAST RESIN Transformers are free of partial discharge at least up to 1. 2 times of the rated voltage. The coating of the core with an epoxy resin have lead to an appreciable noise reduction. Noise is also reduced due to the sound suppresing effect of the step lap clitting. Based on the high thermal time constant factor of the windings, LS CAST RSIN Transformers can be overloaded for a short duration considerably highly than oil-immersed transformers. It has a greater capability to withstand sudden high overloads such as might be encountered in heavy traction applications. LS CAST RESIN Transformers are very resistant to impulse voltage. Impulse withstand leaves to 22kW are available because of careful design and special structure. Maintenance is almost completely eleminated. No checking of liquid level and no dielectric test for moisture absorption is required. Due to the smooth coil surface, heavy dirt and dust build up is eleminated even under the worst circumstances. The recommended routine maintenance is an occasional visual inspection. LS CAST RESIN Transformers have a very excellent characteristic of self fire-extinguishing and fire resistance. So there would be no fear of spread of fire even if fire took place around the electricity room.
