One of the important considerations when choosing an armoured cable is the size. The size of the cable is determined by the diameter of the wires and the casing wall thickness. The standard values for armoured cable sizes are established to ensure safety and functionality.
The table below shows the standard values and tolerances for armoured cable sizes:
Cable diameter (D) | Standard values | Tolerance
-------------------|-----------------|------------
0.5 | 0.025 | 0.05
1.0 | 0.025 | 0.10
1.5 | 0.02 | -
As you can see, the tolerance values indicate the allowable deviation from the standard values. For example, for a cable diameter of 1.0, the standard value is 0.025, with a tolerance of 0.10. This means that the actual diameter of the cable can vary from 0.915mm to 1.085mm and still be considered within the standard.
Apart from the wire and casing diameter, another important factor to consider is the insulation layer thickness. This layer is important to protect the wire from conducting electricity to its surroundings and to maintain the integrity of the electrical circuit. The minimum insulation layer thickness is 0.04 for a cable diameter of 0.5, 0.08 for a diameter of 1.0, and 0.08 for a diameter of 1.5.
When installing armoured cables, it is important to follow the manufacturer's instructions and guidelines to ensure proper handling and installation. If you are not familiar with electrical wiring, it is best to seek the help of a licensed electrician.
When looking for an armoured cable supplier, it is important to find one that offers high-quality products that meet industry standards.
