When selecting cables for high-temperature applications, it’s important to consider both the current-carrying capacity and the temperature.

High temperatures can affect the cable's ability to carry current, so ensure that the selected cable can handle the expected load at elevated temperatures.

B. Proper Termination Techniques

Proper termination is essential for the safe operation of any cable. Use the appropriate connectors and ensure that all terminations are made with the correct crimping or tightening techniques to prevent failures.

C. Avoid Sharp Bends and Mechanical Stress

To prevent damage, avoid sharp bends and excessive mechanical stress during installation. Adhere to the minimum bending radius as per DIN VDE 0298-4.
