LS RESIN CORE TRANSFORMERS

Resin Core Transformers (Oil Free)

Features • Environmentally safe: 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. • Low maintenance: Maintenance is almost completely eliminated. 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 are eliminated. The recommended routine maintenance is an occasional visual inspection.						• High overload capability: Based on the high thermal time constant factor of the windings, LS Cast Resin Transformers can be overloaded for a short duration. Considerably higher than traditional oil transformers. It has a greater capability to withstand sudden high overloads such as might be encountered in heavy traction applications. • Moisture proof • High impulse strength • No partial discharge • Fire resistant • Low noise • Standard: IEC 60076-11 (2004)
Information Optional Accessories
• F Class, 100K Temperature Rise, 50Hz • 12kV Class, 75BIL					• Forced cooling fans • PT100 probes and controllers
