Einphasige und Dreiphasige Kernlose Drossel
Single-phase and three-phase chokes with air-core produced by Elhand Transformatory are used in systems with capacitors batteries as smoothing chokes or filtering chokes. They also operate as shunt reactors to compensate capacitive reactive power of power lines or as limiting chokes that reduce the value of short-circuit currents. They may also operate as limiting chokes that limit the steepness of voltage rise du/dt or current rise di/dt. Air-core coils are produced using modern components and technologies in the manufacturing process combined with innovative design solutions and can meet the highest standards of quality and reliability. The windings of air-core coils inductors are made of cooper wires and appropriately selected insulation materials. The choke structure made of paramagnetic steel alloys and glass-epoxy components effectively eliminates arising of additional losses. We produce chokes according to the individual and unique customer's specifications
