There are many kinds of cable lines above the sales market, in which control cables and power cables are very common in our daily life, the following is to take you to understand how to distinguish control cables and power cables. The key lies in the following aspects:

1, cable model difference

The number of cores of the control cable is a lot, the general number is 61 cores, and it can be a large number if customized according to the specific regulations of customers. The power cable core is generally 5 core, and the control cable is used to transmit the control data signal. The power cable is used in the main line of the power supply system to transmit and adjust large function electromagnetic energy. The control cable immediately transfers the power from the power supply point of the power supply system to the power connection line of various distribution machines and equipment tools.



When controlling a reserved core grounding device in the cable, the amplitude value of the interference working voltage can be reduced to 25%-50%, and the implementation is simple, and the engineering cost of the wire and cable is very small.

2, metal material shielding and shielding layer grounding device

Metal material shielding is a key countermeasure to weaken and prevent interference of electrical equipment, including single-core total shielding, separate shielding and two-layer total shielding. The selection of the shielding form of the metal material of the control cable should be recorded according to the level of the interference hazard of the electrical equipment that is likely to be caused, and the comprehensive interference suppression countermeasures should be recorded to achieve the provisions of reducing interference and overvoltage. The higher the demand for the actual effect of anti-interference, the greater the corresponding investment, the selection of steel armored cables, stainless steel wire hand-woven total shielding, the price of the cable is about 10% - 20%.

The control interference in the weak current loop, because its own signal is strong, can choose a control cable without metal material shielding except that it is located in the high-voltage distribution equipment or the parallel plane adjacent to the high-voltage cable line is longer. When the control cable used in the weak electronic signal control loop is located in the natural environment with interference hazards and does not have a good anti-interference countermeasure, it is appropriate to use the control cable with metal material shielding to avoid the interference of electrical equipment that will cause wrong operation or make the insulation layer penetrate the damage of the low electrical frequency data signal loop. If the control cable of the weak current installation circuit can be opened with sufficient spacing of the power cable, or laid in the seamless steel pipe, it is likely to reduce the interference of external electrical equipment to the allowable degree.

3, specifications, models, tone

The standard provision for control cables is 9330, and the standard provision for power cables is GB12706. The color of the insulated cable core of the control cable is generally gray and black with yellow characters, and the low voltage of the power cable is generally toned. The cross section of the control cable is generally impossible to exceed 10 square, and the power cable is mainly for the transportation of power engineering, which is generally a large cross section.

In addition, because the raw materials used in the production process are not the same, the key raw materials for the production of cable are electrolytic nickel, insulating layer material and wire sheath. The power cable is used to transmit and adjust the large function electromagnetic energy in the main trunk line of the power supply system, and the control cable immediately transmits the electricity from the power supply point of the power supply system to the power connection line of various distribution machines and equipment tools. The rated current of the power cable is generally 0.6/1kV and above, and the key of the control cable is 450/750V. When the power cable and control cable of the same size are manufactured, the insulation resistance and bushing of the power cable are thicker than that of the control cable.

Qingdao Tianxing Cable Co., Ltd. focuses on the production of customized wire and cable manufacturers, main: fire wire and cable, power cable, control cable and other products, exported to more than 40 countries and regions around the world, the annual production capacity of 1 billion yuan. 6000 square meters of storage, standing hundreds of millions of inventory, order demand for rapid distribution and delivery, large prices more favorable.
