3 core armoured cable carrying capacity list
Cable carrying capacity refers to the amount of current passing by a cable line in the transmission of electric energy, in the condition of thermal stability, when the cable conductor achieve long-term allowable working temperature, cable carrying capacity is called the cable allowing carrying capacity for a long time.
 
The carrying capacity of the wire is related to the conductor cross section, the wire material, the model, the laying method and the environment temperature. The carrying capacity of a variety of wires is usually obtained from the manual.
