FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

Why does a VFD mining motor need a symmetrical 3 + 3 core arrangement?
Variable-frequency PWM inverters switch at high dV/dt, inducing high-frequency common-mode currents. Splitting the protective earth into three equal conductors placed at 120° in the outer interstices balances phase-to-earth capacitance and inductance across all three phases, preventing circulating shaft currents that pit motor bearings.
What is the difference between this VDE (N)SSHCÖU VFD cable and the 2 kV ICEA VFD Mining Power Cable?
This (N)SSHCÖU cable is built to DIN VDE 0250-812 for 0.6/1 kV (and 640/1,140 V) metric systems (16–240 mm²) with a 3P + 3PE + concentric copper braid screen and 5GM5 yellow/black rubber sheath. Our 2 kV VFD Mining Power Cable is built to ICEA S-75-381 (2 AWG–500 kcmil) with 3P + 3G + 1 ground-check pilot and foil + braid shield.
How should the concentric copper braid screen be terminated at the inverter and motor?
Terminate the concentric tinned-copper braid 360° around the cable circumference using an EMC compression gland or circumferential shield clamp at both the VFD cabinet and the motor terminal box. Avoid twisting the braid into a long pigtail, which adds inductance at high PWM switching frequencies.
Can (N)SSHCÖU 0.6/1 kV be used on 1,000 V or 1,140 V underground mining drives?
Yes. Although nominally designated U0/U = 0.6/1 kV under DIN VDE 0250-812, the 3GI3 EPR insulation system is tested at 5 kV AC for 5 minutes and is explicitly permitted for three-phase mining systems with U0/U = 640/1,140 V (maximum operating voltage 0.7/1.2 kV AC).
How is the split protective earth cross-section written in the size table?
For 16 mm² and 25 mm², the table lists each individual earth conductor ('3 × 16 + 3 × 2.5' means three 2.5 mm² earths = 7.5 mm² total). From 35 mm² to 240 mm², it uses standard DIN VDE notation ('3 × 35 + 3 × 16/3'), where '16/3' indicates three split earths totalling 16 mm².
