11 technical data:
1, according to DIN VDE fifth class soft stranded copper conductors.
2 insulation, weather resistance and heat-resistant resin.
3, soft shield.
Along with the development of the frequency control drive technology, more and more high to the requirement of the variable frequency drive system, especially for the fast switch IG BT semiconductor modern frequency conversion technology, though it has high pulse frequency and more time only milliseconds, but they would have a positive magnetic field on the surrounding environment.In order to make the inverter work normally, not affected by electromagnetic interference, so the connection between the inverter and three phase ac motor cable requires has anti-jamming performance, low effective capacitance and low transfer impedance.
