Products Description
The VSD/EMC Flame Retardant Cable is engineered for variable speed drive (VSD) systems to resolve core challenges of high-frequency harmonic interference and voltage spikes in industrial motor power transmission.
Conection of motors with variable frequency drive systems.
VSD systems generate PWM (Pulse Width Modulation) signals with steep voltage rise (6kV/μs) and common-mode voltage, which can cause insulation breakdown and electromagnetic interference (EMI). This cable uses:
Symmetrical 3C+3E core structure: Reduces distributed capacitance (≤100pF/m) and inductance (≤0.5μH/m) to minimize harmonic energy loss.
XLPE insulation (cross-linked polyethylene): Withstands 0.6/1kV rated voltage and 12kV impulse voltage, meeting NEMA MG-1 Part 31 requirements for motor insulation protection.
Copper braid shielding: Diverts common-mode current to ground, suppressing EMI radiation (compliant with EN 55011 Class A) and preventing interference with adjacent control/communication cables.
Key Materials & Performance
Conductor: Class 2 stranded bare copper (99.95% purity) | Ensures high conductivity (≥58MS/m) and mechanical flexibility.
Insulation: XLPE (cross-linked at 180℃) | Resists thermal aging (10,000h @90℃, tensile strength retention ≥80%).
Shielding: Tinned copper braid (85% coverage) | Provides low transfer impedance (≤50mΩ/m @1MHz) for efficient EMI suppression.
Sheath: Flame-retardant PVC (halogen-free optional) | Passes IEC 60332-3 Cat.B (no ignition of cotton by droplets).

FAQ
01.What cable length is recommended for VSD systems?
≤30m: No output reactor needed (complies with NEMA MG-1).
30-90m: Use an output reactor (e.g., 4.6mH/11A for 5.5kW motors).
90m: Add an EMC filter (consult JSH engineers for matching).
02.Is this cable compatible with CE certification requirements?
03.Can I get a halogen-free version?
04.What is the lead time for custom specifications?
05.Do you provide test reports?
