Typical applications of CABLES FOR WIND FARMS

Select...
Array collection Turbine Internal Yaw and Pitch Auxiliary control

Medium Voltage array collection
Cables that aggregate power from multiple turbines, often laid underground across the wind farm site. They are designed for direct burial, with robust mechanical and moisture protection to connect individual turbines to the main substation.

Turbine internal power harness
These flexible, torsion-resistant cables run from the nacelle down the tower to the base. They must endure constant movement, bending, and vibration to carry generator power and control signals reliably.

Yaw and Pitch System Power & Control
Cables that supply and control the motors which rotate the nacelle (yaw) and adjust blade angle (pitch). They require exceptional flexibility for continuous movement and high flex-cycle endurance to optimize turbine alignment with wind direction.

Auxiliary control and service systems
These cables power and control critical support systems within the nacelle and tower, including heating, cooling, lubrication pumps, and backup motors. They ensure the turbine's operational integrity and safety in harsh conditions.

FAQs (Frequently Asked Questions) about cables for wind farms

Wind farm cables must comply with IEC 60502 for MV collection cables, IEC 60228 for conductors, and GL/DNV certification for turbine internal cables. We manufacture to all major wind industry standards.

Yes. Our torsion cables are specifically engineered for the twisting motion of wind turbine nacelles, rated for millions of torsion cycles and tested to IEC 60228 Class 6 stranding.

Onshore wind farm inter-array cables are typically rated at 36kV (12/20kV or 18/30kV), with direct-burial armoured XLPE cables being the standard choice for inter-turbine underground connections.

Aluminium is widely used for wind farm inter-array cables due to cost and weight advantages at larger cross-sections (95mm² to 630mm²). Copper is used where higher current density or jointing constraints apply.

Yes. We offer low-temperature-rated variants of our wind farm cables, tested for installation and operation at temperatures down to -40°C for Arctic and high-altitude onshore wind projects.

Yes. We offer a complete wind farm cable package with full project logistics and technical support from our energy sector team.

Yes. We have supplied cables to major offshore wind farm projects internationally, covering turbine internals through to grid connection. Our project engineering team can review specifications, provide technical submittals, and support the approval process with energy developers, turbine manufacturers, and principal contractors.

For inter-turbine array and collection circuits, Top Cable’s X-VOLT medium voltage range (RHZ1 XLPE or HEPRZ1 HEPR, aluminium or copper) covers 6/10 kV up to 18/30 kV and beyond, halogen-free, with optional water-blocked (-OL/-2OL) construction for offshore conditions.

The array (collection) grid uses medium voltage cable. Top Cable’s X-VOLT RHZ1/HEPRZ1 carries roughly 10-33 kV between turbines and the substation, with aluminium or copper conductors and a copper screen, manufactured to IEC 60502-2.

Top Cable’s X-VOLT RHZ1 (AS) Al is an XLPE-insulated, halogen-free aluminium MV cable rated 6/10-18/30 kV, 90C service temperature, CPR class Cca, with an optional longitudinally water-tight (-OL/-2OL) version for buried array circuits

Yes. X-VOLT RHZ1/HEPRZ1 MV cables are designed for transmission and distribution up to 33/69 kV, are UV-resistant and buriable, so they suit onshore export runs from the wind farm to the grid connection point.

Yaw and pitch systems demand torsion- and flex-resistant cable. Top Cable’s flexible rubber and PUR-sheathed ranges, such as XTREM H07RN-F, withstand the repeated twisting inside the nacelle.

Use water-blocked or armoured cable. Top Cable’s X-VOLT -OL/-2OL versions add longitudinal water tightness for buried MV runs, and POWERHARD armoured LV cables resist crushing and impact.

Top Cable’s X-VOLT RHZ1/HEPRZ1 aluminium MV range covers 33 kV (and up to 69 kV) collection circuits, with XLPE or HEPR insulation, a copper screen and halogen-free, CPR-rated sheathing.

Both use MV array cable, but offshore circuits prioritise water tightness and mechanical robustness (Top Cable X-VOLT -OL/-2OL water-blocked), while onshore export runs focus on burial, UV resistance and CPR fire class.

Top Cable manufactures the X-VOLT MV range (RHZ1, HEPRZ1, aluminium and copper, 6/10-69 kV) used in onshore and offshore wind, produced to IEC 60502-2 and HD 620.

Cross-section depends on voltage, current and run length. For a 5 MW turbine on a 33 kV array this sits in the large-section X-VOLT RHZ1/HEPRZ1 aluminium range; size it against the ampacity tables in the Top Cable datasheet.
