Find the right cable cross-section with just one click

Which cable cross-section is right for my application? This question is crucial when it comes to correctly dimensioning cables. By selecting the correct cable size, planners ensure that cables can dissipate the heat generated by electrical resistance. This protects the electrical installation from overheating, fire hazards, and energy loss. The cable cross-section calculator from TKD Kabel provides users with an important initial estimate of the cable cross-section they should consider for their installation.

Simple operation facilitates comparative calculations

They only need to enter a few values. The cable cross-section is determined from the relationship between electrical current, voltage, and resistance. The corresponding formula and the resistance values ​​for common metals are stored in the online calculator. Users simply select their intended cable material (copper, aluminum, etc.), enter the power, voltage, and intended length, and with just one click, they immediately receive the required cable cross-section in ^mm² . This also makes comparative calculations easy.

For international projects: Conversion to AWG included

With the TKD Kabel online calculator, the determined cable cross-sections can also be converted to AWG, the American Wire Gauge. This logarithmic coding for wire diameters is derived from the number of drawing dies used to produce a defined cross-section. It is a widely used standard in North America. By converting cable cross-sections from ^mm² to AWG, users can select the appropriate cable types for electrical installations in international projects, even in order to meet specified standards.

Experts can be reached directly from the website

While the cable cross-section is a key parameter for assessing a cable's current-carrying capacity—that is, how much current it can safely carry over a long period of time—it is not the only one. The materials used, the installation method, and the ambient temperature are also crucial for the operational reliability of the electrical installation. TKD Kabel therefore recommends evaluating and specifying the determined cross-section in the context of these application-specific conditions. The specialist for complete cable and wire solutions supports customers with comprehensive advice on technical questions regarding the application, product properties, or material selection. For example, you can start a chat with a TKD expert or schedule a video consultation directly from the TKD website.
