Induction heating for the cable and wire industry

Induction heating for the cable and wire industry

The unrivaled accuracy and control of induction heating—and the fact that it can be used on virtually any electrically conductive material—make it ideal for many key tasks in the manufacture of cable and wire.

 

Most of the equipment we supply to the cable and wire industry is used in the following areas:

 

Plasma technology for the cable and wire industry

One hallmark of EFD Induction has been our success at finding new exciting uses for induction heating. A typical example is induction heating for the plasma industry. 

 

The whole purpose of plasma is to create a very pure glass material, which can, for example, facilitate the passage of light signals through optical cable. That’s exactly why induction heating is so suited to the cable and wire industry.

 

Traditional furnace heating can contaminate the melted glass with impurities. Induction heating however is a totally clean process that lowers the costs-as there's no need to buy and maintain purification machines.

Induction postheating in the cable and wire industry

EFD Induction has for years worked closely with the cable and wire industry on developing induction solutions.

 

Using postheating for cables speeds up the process of vulcanization of the insulation layer. In addition, induction heating is accurate and controllable, and the output power is in most cases controlled via the line speed.

  

Induction postheating is also used for wires, tubes and strands, for shaping objects or faster drying of paint.

Induction preheating the cable and wire industry

EFD Induction supplies numerous preheating solutions for the cable and wire industry. Heating before the extruder is the most common induction application in a cable production line. Using the preheater will decrease the cross-linking time and enable a faster line speed.

 

Preheating with induction instead of with a conventional method directly transfers the heat to the wire or the cable core. The material is heated to the right temperature in a very short time (exactly how short depends on the line speed and the coil length).  

 

Induction also means that the actual hardening process begins at the core. The result is better insulation with lower porosity.
