Coaxial Cables

The Cable

Thermo International builds 3 different Coaxial cables for use with induction heating systems. All cables feature a robust Non Conductive outer hose and high pressure center conductor that creates a single electrical and water path. This makes changing coils in the field much easier as the electrical and water paths are one in the same. High pressure ratings well exceeding 5X for personnel protection and electrical grade silicone rubber molded end boots make the cable the most advanced and versatile cable on the market. With both high flow and high current models available as well as a smaller and larger size available these cables find many uses within the induction heating field and are specifically adapted to transfer power between 3 and 12 kHz up to 200 kW of power.


Originally designed by Jeff Weinacker in his off hours during the 1994 slow season. The coaxial cable was built and proven to be successful for its intended application. Although other companies made cables at the time, none had the same capabilities nor were adapted to the specific use the cable was intended for.

Fast forward to 2014 and the original design is well outdated. Thermo stepped in and provided a much needed overhaul updating the design and expanding the product line while correcting the flaws. This produced a new product that not only preforms better electrically but has been adapted to improve its capabilities.
