When your installation demands medium‑voltage cables that can snake through trays, coils, and confined spaces—yet still withstand electrical, mechanical, and environmental stresses—you need a Flexible Medium Voltage Cable engineered for both performance and pliability. Our comprehensive portfolio spans all major voltage classes (3.6/6 kV, 6/10 kV, 8.7/15 kV, 26/35 kV) with options for single‑ or multi‑core, shielded, armoured, and special‑compound jackets. Here’s why our Flexible Medium Voltage Cable stands head and shoulders above the competition.
Cables rated in the medium‑voltage range carry significant energy; any failure can lead to downtime, safety hazards, or equipment damage. When flexibility is also a requirement—for reeling drums, dynamic machinery, or compact routing—you cannot compromise on materials or construction. A top‑tier Flexible Medium Voltage Cable delivers:
Superior Dielectric Integrity
XLPE or EPR Insulation retains its permittivity across –40 °C to +90 °C, preventing water treeing and dielectric breakdown in both static and flexing applications.
Semiconductive Shields applied over insulation and metal shields ensure uniform electrical stress distribution and minimize partial discharges.
Exceptional Mechanical Pliability
Fine‑Strand Conductors (Class 5 or Class 6) enable bending radii as low as 7× overall diameter, critical for tight conduit runs and reel‑mounted equipment.
Braided or Tape Armour options reinforce against crushing, torsion, and abrasion while still permitting movement.
Environmental and Chemical Resistance
Thermosetting Jackets (CPE, CPE/LSZH blends, polyurethane) resist oils, UV, ozone, and chemicals—even under repeated bending.
Water‑Blocking Layers for direct burial or submersible sections maintain flexibility without moisture ingress.
Regulatory and Application Compliance
Meets UL 1072, IEEE 1580, IEC 60502‑2, MSHA, ICEA, and marine/utility specifications.
Available fire‑performance variants (LSZH, low‑smoke zero‑halogen) for confined or public spaces.
Investing in a truly Flexible Medium Voltage Cable minimizes installation headaches and long‑term maintenance costs, ensuring your power infrastructure keeps running—no matter how it’s routed.

Each Flexible Medium Voltage Cable model can be tailored with integrated fiber, monitoring conductors, or fire‑performance jackets to meet your exact project needs.
Our Flexible Medium Voltage Cable solutions excel in environments where static cables fail:
Variable Frequency Drive (VFD) Systems
VFD inverters often sit in compact control cabinets. Flexible 6/10 kV and 8.7/15 kV cables with precision shielding curb common‑mode currents and bearing damage while navigating tight cabinet bends.
Reeling & Mobile Equipment
Draglines, cranes, and mining machines demand cables that flex thousands of cycles. Our 3.6/6 kV fine‑strand, steel‑tape‑armoured flex cables withstand abrasion, oil, and torsion on moving reels.
Industrial Robots & CNC Machinery
Dynamic motion systems in factories require cables with constant flex ratings. Flexible Medium Voltage Cable variants with polyurethane jackets deliver reliable power to gantries and robotic arms.
Offshore & Marine Installations
On decks and platforms, cables face salt spray, UV, and mechanical stress. 8.7/15 kV and 26/35 kV flexible cables with CPE/LSZH jackets and steel‑wire armour maintain integrity in corrosive, high‑motion settings.
Renewable Energy & Substations
In wind‑farm switchgear, flexible inter‑array cables allow easy routing in turbine nacelles. Substation bus‑duct connections benefit from compact bend radii and high‑temperature XLPE insulation.
“Switching to your 8.7/15 kV flexible medium voltage cable for our VFD rigs cut downtime by 60%. The tight bend capabilities made installation a breeze.”
—Javier L., Automation Supervisor, SteelWorks Co.
“Our dragline reeling service life more than doubled with your 3.6/6 kV flex cable—no more cable cuts or unplanned maintenance.”
—Priya N., Maintenance Manager, OpenPit Mining Ltd.
Choosing the optimal Flexible Medium Voltage Cable requires balancing electrical and mechanical criteria:
Voltage Rating & Application
3.6/6 kV for portable tools, small VFDs, and feeder flex sections
6/10 kV & 8.7/15 kV for standard industrial motor feeders and distribution loops
26/35 kV for primary distribution and high‑power machinery
Conductor Material & Stranding Class
Copper for highest conductivity; aluminium for weight‑sensitive runs
Class 5/6 fine stranding for maximum flexibility; Class 2/3 for semi‑flex projects
Insulation & Shielding
Choose XLPE for low‑loss, high‑temperature applications; EPR for extreme pliability and oil resistance
Semiconductive tape + copper shield vs. foil + braid for EMI control and fault paths
Armour & Jacket Compound
Steel tape armour when bending on reels; steel wire armour for torsion and crushing
CPE, LSZH, or polyurethane jackets for oil, UV, chemical, or fire‑performance needs
Mechanical Requirements
Verify minimum bend radius—our flex cables achieve as low as 7× diameter under dynamic load
Assess temperature range, flex cycles, and installation environment
Additional Features
Integrated fiber or instrumentation cores for monitoring
Water‑blocking gels or tapes for direct‑burial flex sections
Custom color jackets, printed markings, and drum labeling
Our engineers work with you to pinpoint the exact Flexible Medium Voltage Cable specification that matches your technical and operational goals.
To maximize the service life of any Flexible Medium Voltage Cable, follow these guidelines:
Respect Bend Radii
Even high‑flex cables have limits. Observe the manufacturer’s minimum dynamic and static bend radius ratings to prevent conductor fatigue.
Use Proper Terminations
Employ certified stress cones, gland plates, and lugs rated for your voltage class to maintain shield continuity and prevent moisture ingress.
Secure and Support
Cable cleats, trays, and clamps prevent undue movement. On reels, use rollers and guide arms to minimize abrasion during pay‑out and retraction.
Pre‑Commissioning Tests
Perform high‑potential (Hi‑Pot) tests, partial‑discharge diagnostics, and continuity checks before energization—especially critical for flex installations.
Routine Inspections
Monitor flex sections for jacket wear, armour exposure, or shield damage—replace or re‑terminate before failure.
Adhering to these practices ensures your Flexible Medium Voltage Cable continues to deliver reliable power under the harshest flex conditions.
