Symmetrical Double-Shielded XLPE VFD Cable with Three Ground Wires
This symmetrical VFD cable features three XLPE-insulated phase conductors and three grounding conductors arranged evenly around the cable core. Combined foil and copper-braid shielding delivers effective EMC protection, while the symmetrical grounding design helps reduce electromagnetic interference in industrial motor-drive systems.
Key Highlights
Three symmetrical grounding conductors · XLPE phase-core insulation · 600/1000 V rating · Low-capacitance construction · 100% double shielding · Effective EMC protection · Oil Res I and II · Sunlight resistant · Flame retardant · Cold resistant down to -40°C · Suitable for exposed runs and direct burial · PFAS-free · RoHS compliant
This symmetrical XLPE VFD cable is designed for power connections between variable frequency drive controllers and industrial AC motors. The three evenly distributed grounding conductors make it particularly suitable for drive systems requiring symmetrical electrical characteristics and effective suppression of common-mode interference.
Typical applications include:
- Variable frequency drive motor connections
- Servo motors and adjustable-speed drives
- Industrial automation and production equipment
- Pumps, fans, compressors and conveyor systems
- Long-distance motor power connections
- Cable trays and exposed industrial runs
- Indoor, outdoor and direct-burial installations where permitted

THE FACTORY
BEHIND EVERY METER
Founded in 2007 in Foshan, Guangdong, Hulk Electric has grown from a regional producer into a globally recognised manufacturer of customised industrial cable solutions. Our 10,000㎡ facility runs on Toyota Production System lean principles, operated by 150+ skilled professionals producing over 300,000 metres every month.
Every cable you see on this page — including the HK-TRVV series — is engineered, extruded, tested, and shipped from that single facility. No trading company sits between you and the extrusion line.
Source Factory
Direct manufacturer — no middlemen, no markups. You deal with the engineers who run the line.
Deep Customization
Conductor, shielding, jacket compound, colour coding, certification — built to your exact spec.
7-Day Sampling
Rapid samples for new specifications. 15-day lead time on standard production orders.
Global Compliance
35+ certifications covering UL, CE, TÜV, IEC, RoHS and REACH for every major market.
BEFORE YOU ORDER
For stocked configurations listed in the ordering table, MOQ is 100 metres per specification. Custom configurations — non-standard core counts, jacket colours, or special compounds — carry a 500 metre MOQ. Samples of 5–10 metres are available free of charge for qualification testing.
Use shielded (P or PP suffix) whenever the cable runs alongside servo drives, VFDs, or inverters, or when carrying encoder, sensor, or analogue signals. Unshielded is suitable for pure power distribution and simple on/off control lines. If in doubt, our engineering team can review your cabinet layout and advise — this is included with any quotation.
Yes. Send us the existing part number or a sample and we will produce a cross-reference specification with matching electrical, mechanical, and dimensional characteristics. Most cross-references are turned around within 3 working days, with a physical sample following within 7 days.
Standard shipments include the CE Declaration of Conformity, RoHS and REACH statements, and the batch test report. UL Recognition (UL 2464 / UL 20549) is available on request for North American projects — specify this at the quotation stage as it affects the material specification.
Standard configurations ship in 15 working days from order confirmation. Custom-engineered specifications typically require 20–25 working days, depending on compound availability. Rapid sampling for new specifications is 7 days. We will confirm the exact date in writing with your order acknowledgement.
