VARIABLE FREQUENCY DRIVE CABLE VFD

Construction

Phase conductors: Bare copper, soft temper, flexible stranding: class 5 – sizes from 35 to 300 mm².
Insulation: Ethylene Propylene Rubber thermoset compound (HEPR) for 90 °C maximum operation conductor temperature, 130 °C overload and 250 °C short-circuit.
Symmetrical neutral conductors: Bare copper, soft temper, flexible stranding.
Lay-up: the 3 phase insulated conductors are laid up together with the 3 neutral conductors, which are placed in the interstices between adjacent phase conductors
Metallic shield: Bare copper tape helically applied, with a minimum overlap of 15 %.
Overall jacket: Flame retardant polyvinylchloride PVC ST2 thermoplastic compound, lead free, black color.

APPLICATION

VFD CABLES are applied as variable frequency drive circuits, connecting the motor to the inverter. They are designed  for fixed installations, and can be installed in trays, ducts, shelves or directly buried.

Benefits of VFD CABLES for frequency inverters having symmetrical neutral in relation to frequency inverter cables having concentric neutral:

  • Lower outer diameter;
  • Lower weight;
  • Easier handling and installation;
  • Lower bending radius;
  • Better electrical performance due to the greater balance of the induced voltages on the neutrals, as they will be symmetrically arranged, in order to cancel out the induced voltages.
  • Suitable for higher power engines
