Mil gmbH

World-wide increasing precision, reliability, and safety requirements in Temperature, Control

and Measurement Engineering can no longer be satisfied by conventional cables causing a

rising need for mineral insulated lines. Applications cover everything from the simple build-

ing of furnaces to the production of nuclear power plants.

Our product catalogue will guide you through a selection of state-of-the-art mineral insulated

thermocouples and heating cables. We can offer thereby 35 years of experience.

The close collaboration with leading customers - world-wide - is the guarantor for a broadly

varied offer, with a maximum flexibility and highest reliability. Our head office is in the city of

Hanau, Germany. From here we service our national and international customers.

The MiL GmbH is both a manufacturer and a service provider. We offer to our customers

everything from professional consultation to custom-made products.

Yours sincerely

Note

1) Tolerance on conductor resistance is ± 5 % for all 300 volt 2/C cables.

2) The maximum recom-mended loading is 200 watts per metre for all 300 volt 2/C cables.

3) For pipe tracing, the maximum recommend-ed watts per metre of cable may be reduced to the pipe to maintain or process temperature.

4) Minimum bend radius is 5 times nominal cable diameter.

To ensure a sufficient level of dielectric strength between conductor and sheath, the insulation lay-er thickness was selected as ≥ 1.0 mm for all types in the standard program including the cold cable. it follows that all cables can be operated up to 800 V.

Note 1) Tolerance on conductor

resistance is ± 5 % for all 800 volt cables.
