Multi-strand CTC (Continuously Transposed Cable), an insulation-coated, copper wire used primarily in the production of large transformers, can be quickly stripped using induction technology. At a temperature of 1,112° F (600° C), the coating evaporates within seconds, making the process ideal for industrial applications such as the production of transformers or electrical machinery. Prior to connection to the transformer, the ends of the wires must be stripped of this coating – a standard process that takes some time. This can be accomplished using a variety of methods. However, sanding down the insulation is difficult if the wire has several layers, and a process using open flames carries certain health and safety risks. Considering these factors, induction heating is a quicker and safer alternative. In addition, heat is distributed evenly in the metal – regardless of the complexity of the wire’s winding – and causes fewer defects.

Induction heating benefits for wire stripping
The biggest advantage of using induction heat rather than a flame is the ability to focus the heat only where you need it rather than allowing the heat to travel up the wire.
Additional benefits include:
- Uniform stripping
- Fast processes
- Precise control over location of heat
- Fewer health and safety risks
- Power efficiency
- Customized generator configuration
Induction generators and coils for stripping copper wire
Since the coating on wires is typically only on the surface, eldec LLC recommends using a high frequency, low cost generator like the PICO-S as well as a custom-made, multi-wind, outside heating coil that will surround and heat the wire. A chiller will be required to keep the power supply and induction heating coil cool. If you prefer an on-board chiller or need additional features, a MiniMICO or an ECO LINE generator may be better fit for you. Our experienced technicians will review your process and help you decide. Longer hose bundles are available if your power supply cannot be placed near the area where wires will be stripped.
