Cable Specifications and Parameters

When selecting the right cable, several key specifications must be considered:

Voltage Rating

This defines the maximum voltage a cable can safely carry. Low-voltage cables are used in residential buildings, while medium- and high-voltage cables are for industrial and utility-scale applications.

Temperature Tolerance

Some environments require cables that can withstand high or low temperatures. XLPE cables, for example, can operate in temperatures up to 90°C, while PVC cables are limited to around 70°C.

Cross-sectional Area

The size of the conductor affects how much current the cable can carry. This is measured in square millimeters (mm²), and larger conductors can carry more current without overheating.

Cable Flexibility

Flexibility is crucial in certain applications, such as robotics or movable equipment. Rubber cables offer the highest flexibility, while PVC-insulated cables are more rigid.
