Remee Wire & Cable has introduced a new line of renewable energy cables designed to meet the needs of wind and solar energy system operators.

The new line of low voltage cables includes:

• Photovoltaic (PV) cable: Cross-linked polyethylene (XLPE) insulation, 600 V to 2,000 V, aluminum (1/0 AWG to 1,000 kcmil), copper (#12 AWG to 1,000 kcmil), stranded. UL 4703. RoHS compliant.Source: Remee Wire & Cable
• Ground wire: Bare copper (#12 AWG to 1,000 kcmil), meets ASTM B1, ASTM B2, ASTM B3, ASTM B8 or ASTM B33 standards. Copper clad steel (CCS 30% or 40% conductivity; #2 AWG to 4/0 AWG), meets ASTM B193, ASTM B227, ASTM B228, ASTM B452 or ASTM B910 standards.
• Fiber optic cable: Single mode, 12 to 96 fibers, RoHS compliant.
• Control/motor tracker cable: Stranded copper conductor (#18 AWG to #6 AWG), CPE/PVC jacket. UL 2277. RoHS compliant.
• Harnesses: PV cable with XLPE insulation, pre-terminated in coils or on reels, cut-to-length (up to 12 strings) with choice of connectors.

These cables can be used in many applications required by PV systems, such as motor tracker cable for directional control of single axis or dual axis solar panels. Solar panels use copper PV wires, which are strung together, resulting in a positive and negative PV cable at the end of the rows. Copper PV harnesses, or strings, carry the power generated from each row to the combiner box (input), which is then carried by aluminum PV cables (output) to the inverter, which converts DC to AC. The inverter is then connected to a transformer to step up the voltage (low to medium), where it ultimately terminates at the substation. Fiber optic cable is used for communication between motors and blocks of solar panels to a final data or meteorological station.

Wind turbine towers employ different types of multi and single conductor cables, including instrumentation, control and power cables, which are connected to transformers located within the nacelle or the base of the tower. The nacelle also utilizes all three types of cables.
