Why should cable coils be kept at room temperature?

Keeping cable coils at room temperature is essential to maintain proper insulation properties. Insulation in cables is designed to protect the conductive materials inside from environmental factors such as moisture, heat, and physical damage. Extreme temperatures can compromise these materials, making them less effective and potentially leading to increased capacitance or reduced dielectric strength. If cables are exposed to either excessive heat or cold, the insulation may become brittle, cracked, or less effective, which can lead to signal loss or failure.

While other factors, such as preventing exposure to harsh weather or avoiding physical stress on the cable, are important considerations during installation and handling, the primary reason for maintaining cables at room temperature is to ensure that the insulation retains its integrity and performs optimally. This ultimately helps in achieving reliable and effective data transmission over the cables.
