VFD inverter to AC motor screened feeder
Primary duty — 100 % concentric copper braid + foil shield contains high dV/dt PWM inverter harmonics.
Product
North American 2,000 V VFD portable mining cable to ICEA S-75-381 with three rope-lay tinned copper phases, three symmetrical green grounds, a yellow ground-check pilot and a 100 % foil + tinned copper braid shield.
Typical values for this cable type, based on ICEA S-75-381 / NEMA WC 58 · CSA C22.2 No. 96 — confirmed in the datasheet and quotation for your order.
Application fit
Heavy-duty MSHA-grade symmetrical screened 2 kV VFD mining power cable for variable-frequency drives on mine hoists, ventilation fans, pumps and conveyors.
Primary duty — 100 % concentric copper braid + foil shield contains high dV/dt PWM inverter harmonics.
Symmetrical split ground cores balance zero-sequence impedance on large AC traction & pump motors.
Flame-retardant CPE/PCP outer jacket for mine roadways, preparation plants and tunnel trays.
Relocatable skid and semi-mobile mine drive connections when minimum bend radius is maintained.
Not intended for high-speed monospiral crane reels.
Use (N)SHTÖU ReelingConstruction
Three rope-lay tinned copper phase cores surround a central yellow ground-check pilot, with three green-insulated grounding conductors placed symmetrically in the three outer interstices, enclosed by a 100 % aluminum/polyester foil + tinned copper braid shield and a reinforced mold-cured CPE jacket.
