When your operations depend on safe, reliable transmission of medium‑voltage power—whether feeding industrial drives, powering offshore platforms, or supplying utilities—you need a medium voltage power cable engineered to excel under electrical, mechanical, and environmental stresses. Our comprehensive portfolio covers the key voltage bands of 3.6/6 kV, 6/10 kV, 8.7/15 kV, and 26/35 kV, delivering unmatched performance, rigorous compliance, and end‑to‑end service.
Medium‑voltage applications carry significant energy levels. A minor insulation defect or shield discontinuity can trigger partial discharges, corona, or catastrophic failures. Choosing a premium medium voltage power cable ensures:
Electrical Integrity
XLPE/EPR Insulation maintains stable dielectric properties from –40 °C to +90 °C, preventing water treeing and electrical ageing.
Composite Shielding (semiconductive tape + copper braid) delivers 360° ground continuity and blocks electromagnetic interference.
Mechanical Robustness
Steel‑Tape or Wire Armour resists crushing and torsional forces in trenched, reel‑mounted, or tray installations.
UV‑ and Oil‑Resistant Outer Jackets withstand harsh outdoor, offshore, and petrochemical environments.
Regulatory Compliance
Meets or exceeds UL 1072, IEEE 1580, IEC 60502‑2, BS 6622, and national grid specifications for medium‑voltage distribution.
Available with marine (DNV, ABS, Lloyd’s) and mining (MSHA, ICEA S‑75‑381) approvals.
Investing in quality medium voltage power cable reduces failure risk, maintenance costs, and unplanned downtime—keeping your systems energized and secure.

Our medium voltage power cable solutions power critical infrastructure across industries:
Industrial Drives & VFD Systems
In 6/10 kV and 8.7/15 kV VFD installations, precision shielding controls common‑mode currents and minimizes bearing damage, enabling stable motor operation in steel mills, paper plants, and waterworks.
Utility Substations & Feeders
3.6/6 kV feeders link indoor switchgear to distribution transformers. Armour and robust jackets protect cables laid in trenches or cable tunnels.
Offshore and Marine Power Distribution
8.7/15 kV and 26/35 kV cables with LSZH or oil‑resistant jackets deliver power to rigs, platforms, and ships—withstanding salt spray, UV exposure, and mechanical stress.
Mining and Tunnelling Operations
Flexible rubber‑insulated, steel‑wire‑armoured cables rated at 3.6/6 kV and 6/10 kV provide reliable energy to continuous miners, roof bolters, and shuttle cars—resisting abrasion, moisture, and chemical attack.
Renewable Energy Installations
Wind‑farm inter‑array circuits often employ 8.7/15 kV cables to optimize power transmission with minimal losses. The low‑loss XLPE insulation enhances overall energy yield.
“Upgrading to your 6/10 kV XLPE‑insulated cables reduced our distribution losses by 12%. The steel‑tape armour also cut our maintenance calls by half.”
—Angela W., Electrical Project Manager, Midwest Utility
“Your 8.7/15 kV LSZH cables passed DNV marine fire tests with ease. Installation on our platform was seamless, and the protection specs are rock solid.”
—Markus R., Offshore Installation Lead
Choosing the optimal medium voltage power cable involves several key considerations:
Voltage Rating & Application
3.6/6 kV: Ideal for low‑voltage feeders, indoor bus‑duct connections, and small VFDs.
6/10 kV & 8.7/15 kV: Standard for industrial motor circuits, VFD drive cables, and switchgear feeders.
26/35 kV: Used in primary distribution, utility feeders, and heavy industrial power loops.
Conductor Material & Size
Copper for highest ampacity and minimal losses.
Aluminium for weight‑sensitive runs; choose larger cross‑sections to match ampacity.
Insulation & Jacket Types
XLPE for high-temperature and low-dielectric-loss applications.
EPR when extreme flexibility or oil resistance is required.
LSZH jackets in confined or public spaces for low-smoke, halogen-free safety.
Mechanical Protection Needs
Steel tape armour for buried or tray installations.
Steel wire armour when cables are on reels or subject to torsion.
Environmental Conditions
UV, oil, chemical, or submersion exposure dictate jacket compound selection (EPDM, TPU, PVC).
Temperature extremes may call for high-heat rated XLPE or EPR insulations.
Additional Features
Integrated monitoring conductors for predictive maintenance.
Metallic moisture barriers for direct burial use.
Custom color coding, printed markings, and drum labeling.
Our technical specialists will walk you through each step, ensuring your medium voltage power cable specification aligns with performance, safety, and budget requirements.
Maintain Proper Bend Radius
Follow manufacturer guidelines—typically 6–8× the cable diameter—to prevent conductor deformation and insulation kinks.
Use Certified Glands and Lugs
Install UL‑ or IEC‑approved terminations rated for your voltage class; ensure shield continuity and moisture seals.
Secure Mechanical Support
Employ cable cleats, trays, and strain reliefs to protect against vibrations, torsion, and abrasion.
Pre‑Energization Testing
Conduct high‑potential (Hi‑Pot) and partial‑discharge tests to verify installation integrity and absence of workmanship defects.
