When your installations—from industrial sites and utilities to renewable‑energy farms and infrastructure projects—depend on reliable medium‑voltage power delivery, you need an MV power cable partner who delivers uncompromising quality, comprehensive customization, and full‑lifecycle support. Our MV power cable portfolio spans all standard classes (3.3/6 kV, 6/10 kV, 8.7/15 kV, 18/30 kV, 26/35 kV), featuring:
XLPE or EPR Insulation for superior dielectric performance
Copper & Aluminum Conductors sized from 16 mm² to 1 000 mm²
Composite Shielding & Armour for full grounding, EMI suppression, and mechanical protection
Tailored Jackets (PVC, LSZH, PU) suited to indoor, outdoor, buried, or subsea applications
Depth of Service: bespoke engineering, test documentation, and global logistics
Below, explore why our MV power cable solutions set the industry standard, how to select the right cable for your project, and how we support you from specification through commissioning and beyond.
Medium‑voltage networks carry high energy densities—small defects can lead to partial discharges, corona, and catastrophic failures. Choosing a premium MV power cable ensures:
Electrical Integrity
XLPE/EPR Insulation maintains stable permittivity from –50 °C to +90 °C, resisting water treeing and thermal ageing.
Precision Semiconductive Layers control electrical stress and prevent insulation breakdown.
Mechanical Durability
Steel‑Tape or Steel‑Wire Armour resists crushing, impacts, and torsion in trenches, tunnels, or reel‑mounted reels.
UV‑ and Chemical‑Resistant Jackets protect against sunlight, oils, acids, and abrasion.
Regulatory Compliance
Conforms to IEC 60502‑2, BS 7870, IEEE 404, and national grid codes.
Optional marine (DNV, ABS), mining (MSHA), and fire (IEC 60332, BS 7629) approvals.
Investing in a top‑tier MV power cable reduces maintenance costs, enhances safety margins, and extends system lifetimes.

Our MV power cable portfolio is engineered for every installation scenario, from indoor switchgear rooms to offshore platforms and underground vaults.
Utility Distribution & Substations
6/10 kV and 8.7/15 kV cables link transformers to switchgear; armour and moisture barriers ensure longevity in trenches and ducts.
Industrial & Mining Operations
Rugged 3.3/6 kV flexible cables power conveyors, crushers, and VFD‑driven motors; steel‑tape armour withstands rock abrasion.
Renewable Energy Integration
8.7/15 kV cables feed wind‑turbine generators; 26/35 kV cables connect solar substations to the grid—XLPE insulation minimizes losses.
Marine & Offshore Platforms
PU‑jacketed, LV‑impregnated MV power cables resist salt spray and mechanical stress on FPSOs, jackups, and offshore wind substations.
Infrastructure & Rail Systems
Urban rail electrification uses 18/30 kV cables in tunnels; halogen‑free jackets and fire‑performance variants ensure passenger safety.
“Upgrading to your 6/10 kV XLPE cable reduced our substation losses by 10%, and the armour cut mechanical faults in half.”
—Angela W., Distribution Engineer, Northern Grid Co.
“Your 8.7/15 kV subsea MV cable sailed through DNV tests—installation on our floating solar platform was seamless.”
—Markus R., Offshore Project Lead
Selecting the optimal MV power cable requires balancing electrical, mechanical, and environmental factors:
Voltage Rating & Application
3.3/6 kV for small sub‑feeders and portable reels.
6/10 kV & 8.7/15 kV for industrial motor circuits, VFDs, and distribution feeders.
18/30 kV & 26/35 kV for utility feeders and primary distribution loops.
Conductor Material & Sizing
Copper for highest ampacity and lowest losses; aluminum for lightweight, cost‑effective runs.
Choose cross‑section based on load current and permissible voltage drop.
Insulation & Shielding
XLPE for low dielectric loss and high‑temperature operation.
EPR when extreme flexibility or chemical resistance is required.
Semiconductive tape and copper braid combination for full shielding.
Armour & Jacket Selection
Steel Tape Armour for burial or tray installations.
Steel Wire Armour for dynamic reel bending and torsion.
Jackets (PVC, LSZH, PU) chosen per exposure (fire, UV, oil, saltwater).
Environmental Conditions
Outdoor: UV‑stabilized and weather‑resistant jackets.
Subsea: Polyurethane jackets and water‑blocking layers.
Fire Zones: Low‑smoke zero‑halogen and fire‑performance variants.
Additional Features
Integrated fiber or copper monitoring cores for predictive maintenance.
Water‑blocking tapes for direct burial.
Color‑coded sheath or printed markers for phase identification.
Our engineering team will guide you through each decision, ensuring your MV power cable spec delivers guaranteed performance under your unique operating conditions.
Proper installation extends service life and maintains reliability:
Maintain Minimum Bend Radius
Observe manufacturer’s bend‑radius guidelines (6×–10× overall cable diameter) to prevent conductor and insulation damage.
Use Certified Terminations
Employ stress cones, gland plates, and lugs rated for your voltage class; ensure shield continuity to ground.
Secure Mechanical Support
Use cable cleats, trays, and clamps rated for MV cables to prevent sagging or abrasion.
Perform Pre‑Commissioning Tests
High‑potential (Hi‑Pot) and partial‑discharge tests verify insulation integrity before energization.
Follow Local Codes & Standards
Adhere to NEC, IEC, IEEE, and regional utility requirements for medium‑voltage installations.
By following these best practices, your MV power cable network will operate safely and reliably for decades.
