Thermal function: Due to the existence of thermal expansion and contraction, we should also pay attention to the thermal function of industrial control cables, that is, the temperature resistance level of industrial control cables, the heating and heat dissipation characteristics of cables for power transmission at working temperatures, current carrying capacity, short circuit and overload capabilities, the thermal deformation and thermal impulse resistance of the constituent materials.

Power distribution circuits? Answer: From the regional substation to the substation of the electricity unit or the power supply line of the city and township, it is the line used to distribute electric energy. Power lines can be divided into according to the erection method? A: Overhead power lines and cable lines. ...

1. In principle, the power cord and network cable of the cabinet should be sorted out separately; 2. The placement of the equipment should be appropriate, avoid squeezing each other, avoid being too high or too low, and avoid being too close to each other; 3. If there are too many devices in the cabinet, the equipment should be numbered; 4. For each line ...

1. Make sure that all equipment in the electrical control cabinet is well grounded, and use short and thick grounding wires to connect to the common grounding point or grounding busbar. Any control equipment connected to the inverter should be co-grounded with it, and likewise ground with short and thick wires; 2. Flat conductors are used, e.g. ...
