1. Power cables are mainly used for power transmission in the main trunk line of the power system, and their voltage is generally above 0.6/1kv; The control cable is mainly used for the power connection of electrical equipment, and its voltage is 450/740V. From the appearance point of view, the cross-section of power cables is larger, and the sheath is thicker. For example, the specifications of power cables can be as large as 500 square meters, while the specifications of control cables are generally not greater than 10 square meters.
2, power cables and control cables belong to two different types of wire products, and their implementation standards are different. Usually the control cable is produced in accordance with the 9330 standard, and the power cable is produced in accordance with the GB12706 standard. If compared from the number of cable cores, the number of cores of the control cable is more, up to 61 cores; The number of cores of power cables is mostly 5 cores or less.
