Are variable-frequency motors generally equipped with variable-frequency cables? It was rarely used in the past. If variable-frequency cables are used, wouldn’t the electromagnetic noise of the motor be reduced?
It means it has not been used; ordinary cables have been used all along, and no problems have occurred
It is best to use variable-frequency cables for powering variable-frequency motors, as this provides good protection for the inverter.
Main properties of variable-frequency cables: 1. The BPYJVP12R-TK and ZRBPYJVP12R-TK types use category 5 soft stranded copper conductors in accordance with the specifications set out in GB/T3956-1997. 2. Cross-linked polyethylene insulation, with good temperature and weather resistance. 3. Low transmission impedance and good electromagnetic compatibility. 4. Low operating capacitance. 5. Good interference resistance and low radiation performance. 6. The symmetric three-core cable design offers better transmission performance compared to four-core cables.
I haven’t used it, so I don’t know what advantages it has over regular cables
Power plant fan, 6700KW, variable frequency; no variable frequency cables have ever been used.
I’ve also heard of this type of cable for the first time; there’s probably no need to use it separately
Motor noise is determined by the inverter carrier frequency
This cable needs to be specified separately. Three thick and three thin
