Medium voltage VFD cable is a specially designed cable specifically used in medium voltage variable frequency systems to meet the connection requirements between variable frequency power supplies and variable frequency motors. The design of this cable aims to improve electromagnetic compatibility, suppress interference, and shield odd harmonics in low efficiency high-order harmonics, thereby enhancing the anti-interference performance of the cable and effectively preventing the generation of high-frequency shaft currents.
The medium voltage VFD cable can withstand variable frequency voltages ranging from 6KV to 10KV, with excellent resistance to voltage surges. It can withstand pulse voltages during high-speed and frequent frequency conversion, providing good protection for variable frequency electrical appliances. In addition, it also has good shielding properties, which can effectively eliminate electromagnetic interference, reduce the noise of variable frequency motors, and ensure the stable operation of the system.
The structure of a medium voltage VFD cable includes the main conductor, conductor shielding layer, insulation layer, insulation shielding layer, semiconducting nylon tape, inner braided shielding layer, secondary conductor, filler, winding layer, outer braided shielding layer, and outer sheath. This type of cable is widely used in industries such as metallurgy, power, and petrochemicals, ensuring stable system operation and improving production efficiency.
