屏蔽控制电缆与普通电力电缆在用途与结构上差异明显：控制电缆主要传输控制信号，对屏蔽与抗干扰要求高，常带铜丝编织或铝箔屏蔽层，芯线较细；电力电缆则以输送电能为主，芯线截面大、绝缘厚，注重载流量与耐压性能。选用时应根据实际回路功能区分，信号回路优先选屏蔽控制电缆，动力回路选电力电缆，避免误用导致干扰或过载。
For customers who want to buy cables, shielding control cables and power cables are relatively easy to confuse, and these two products are actually quite different, must not be confused. Pai De cable gives you a comparison of these two cables.
At the time of production, the insulation and sheath thickness of the power cable is thicker than that of the shield control cable.
1, the shielding control cable belongs to the electrical equipment cable, and the power cable is two of the five categories of cable.
2. The standard of shielded control cable is 9330, and the standard of power cable is GB12706.
3, the color of the insulated core of the shielded control cable is generally black with white characters, and the low voltage of the power cable is generally color separation.
4, the cross-section of the shielded control cable is generally not more than 10 square, the power cable is mainly to transport electricity, generally a large cross-section.
Because of the reasons mentioned above, the specifications of the power cable can generally be large, up to 500 square meters (the range of conventional manufacturers can produce), and then the large cross-section can generally be done by relatively few manufacturers, and the cross-section of the shielded control cable is generally small, and the large is generally not more than 10 square meters.
From the number of cable cores, according to the requirements of the power grid, the power cable is generally 5 cores at most, and the shielded control cable is used to transmit control signals, and the number of cores is more, according to the standard, there are 61 cores, but it can also be produced according to user requirements.
