Hi, from Stapelfeld.

The heating power that a sheathed heating conductor can safely transmit depends largely on the installation method. The better the thermal contact with the component to be heated, the higher the power density can be. The following tables show the recommended power ranges for four different heating conductor diameters with various installation methods.

Installation Methods for Sheathed Heating Cables:

Sheathed Heating Cable, Installation Type 1

Sheathed Heating Cable, Installation Type 2

Sheathed Heating Cable, Installation Type 3

Sheathed Heating Cable, Installation Type 4

Sheathed Heating Cable, Installation Type 5

Sheathed Heating Cable, Installation Type 6

Sheathed Heating Cable, Installation Type 7

Sheathed Heating Cable, Installation Type 8 — Sheathed Heating Cable, Installation Type 9

Explanation of the installation methods:

Installation Methods 1–4: Easy installation by winding, securing with metal strips, or spot welding. Suitable for low heating capacities up to approximately 100 W/m.

Installation Type 5-7: Secure thermal contact achieved by inserting into grooves, brazing, or clamping between plates. Suitable for medium heating capacities up to approximately 300 W/m.

Mounting Method 8-9: Optimal heat transfer through soldering into grooves or embedding in metal. Suitable for high heating outputs exceeding 300 W/m.

Conclusion: Maximum flexibility with minimal space requirements

Sheath heating wires with seamless cold ends are the ultimate solution for complex heating tasks in the tightest of spaces. Their seamless construction and high flexibility make them an indispensable tool for engineers developing innovative and space-saving heating solutions. With a total of 24 different product variants and four diameters (1.0 mm to 3.0 mm), they cover a power range from 25 W up to an impressive 7,500 W. The power tables clearly show how the choice of mounting method influences the maximum power density—a crucial factor in the design of your heating solution.
