Repairing of Induction Furnace Selector Switch or Change Over Switch

Services & Support

Ensure Seamless Power Distribution and Eliminate Arc-Induced Downtime.

The Induction Furnace Changeover Switch (or Selector Switch) is the central point of control for power distribution in multi-furnace or multi-coil systems. This high-current, high-voltage component must operate flawlessly to ensure power is accurately and safely delivered, whether you are running a single melting furnace or switching rapidly between multiple units.

At Electro Power Enterprise, we specialize in expert Induction Furnace Changeover Switch Repair and maintenance, serving the critical operational needs of foundries and steel plants. We minimize the risk of arcing, short-circuits, and unequal power delivery that plague failing switches.

Induction Furnace Changeover & Selector Switch Repair Service

Why Your Changeover Switch Requires Expert Maintenance

Failure in the selector switch is typically mechanical, electrical, or both. Neglect leads to:

  • Dangerous Arcing: Worn contacts create gaps, resulting in severe arcing that damages components and poses a safety risk, leading to forced furnace shutdown.
  • Unequal Power Delivery: Poor contact pressure or misalignment causes high resistance, resulting in uneven power distribution and reduced melting efficiency.
  • Mechanical Seizure: Lack of maintenance can cause the mechanical linkages to seize, making switching impossible and leading to prolonged induction furnace downtime.

Our Specialized Changeover Switch Repair Process

Our comprehensive service rebuilds your high-current selector switch for long-term reliability and precise operation:

1. High-Current Contact Overhaul

1. High-Current Contact Overhaul

We perform complete restoration of the heavy-duty copper contacts. This includes polishing, resurfacing, or replacing worn-out contacts to ensure zero resistance and prevent arcing during power changeover.

2. Mechanical Linkage Alignment

2. Mechanical Linkage Alignment

The mechanical mechanism—the heart of the switch—is disassembled, cleaned and precisely re-aligned. This guarantees smooth, reliable, and instantaneous switching between furnace coils or standby units.

3. Insulation and Terminal Integrity Check

3. Insulation and Terminal Integrity Check

We inspect and repair all insulation barriers, busbar connections, and high-voltage terminals. We focus on securing all fasteners and terminals to eliminate hot spots caused by resistive losses in the power distribution system.

4. Cooling System Service (Where Applicable)

4. Cooling System Service (Where Applicable)

For switches with integrated cooling, we pressure-test and clean the cooling channels to ensure optimal heat dissipation, preventing thermal stress on the contacts and insulation.

5. Operational Testing and Certification

5. Operational Testing and Certification

Every repaired Selector Switch undergoes rigorous testing, verifying both its mechanical action and its electrical performance under dummy load conditions, ensuring it is rated for your full induction power supply capacity.
