Applications of PV Wire
Connecting Solar Panels to a Combiner Box
The most common application of PV wire is connecting solar panels. This involves running a 12 AWG to 8 AWG wire from the combiner box to the ground in a short run (less than 100 feet).
Open Air Installation
This involves tying the PV wire directly to a rack. It’s a fast and cost-effective way to install solar panels, as there is no need for a trench or foundation.
Connecting Combiner Boxes to the Inverter
PV wire can also connect combiner boxes to inverters. These wires are usually power-sized aluminum cables (4/0 AWG to 1000 kcmil) that extend for hundreds of feet.
Direct Burial (Trench) Installation
Direct burial or trench installation can accommodate many circuits in a single common trench. This cost-effective method allows for native backfill to support the foundation.

Applications of LV, MV & HV Cables
Cables are manufactured in a variety of designs and configurations to meet the varied needs of many industries. They are typically divided into three categories based on voltage capacity. Low voltage (LV) cables are designed to handle 2,000 V or less, medium voltage cables (MV) can accommodate between 2,000 V and 35,000 V, and high voltage, or extra-high voltage cables (HV or EHV) are rated for voltage above 35,000 V.
Low Voltage Cables (LV)
Low-voltage cables are used for up to 2,000 volts, depending on the type of current. LV cables can be found in household electronics, consumer products, and electrical devices in residential, commercial, solar farms, and other industrial settings. Typical applications include automation equipment wiring, security systems, lighting, sound systems, and interior building wiring.
The conducting wire in LV cables is typically a tin-copper blend, pure copper, or aluminum. Depending on the intended application, insulation and jacketing materials can be either flexible or rigid. Most LV cables are jacketed in thermoplastic material such as PVC, or thermoset material such as XLPE.
Medium Voltage Cables (MV)
Medium-voltage cables are used for voltages from 2,000 V up to 35,000 V. Since they are incorporated into a broad range of applications, MV cables come in standard voltage ratings, including 5,000 V, 8,000 V, 15,000 V, 25,000 V, and 35,000 V. They are used to distribute power to equipment in mining and industrial applications, and in mobile workstations for repair and maintenance of power lines, transformers, and substations.
MV cables come with both copper and aluminum wires, and insulation is critical. Common materials used in MV cable insulation include ethylene-propylene rubber (EPR), neoprene, cross-linked polyethylene (XLPE), or tree-retardant cross-linked polyethylene (TR-XLPE). The insulation and jacket material used in MV cables differs based on voltage, application, and operating environment.
High Voltage Cables (HV)
High-voltage cables are specifically designed to handle voltage that exceeds 35,000 V. HV cables are used in high-energy applications, including power plants, power transmission, and municipal electrical grids.
When it comes to extruded power transmission cables, materials with higher temperature resistance and high ampacities are desired, such as copper, Milliken copper, enameled copper, and Milliken enameled copper. The high power of HV cables requires highly durable insulation for a variety of underground, underwater, and surface applications. HV cables and joints are structurally reinforced to ensure that voltage is tightly controlled and insulation remains intact.

This blog will discuss how to select the correct cable for renewable energy applications, as well as the optimal solutions we offer for the wind and solar power industries.
Choose the Proper Cable for Renewable Energy Sources
The renewable energy sector involves many cable applications that face unique challenges. Wind turbines and solar power components are subject to extreme weather conditions and can be located in remote, inaccessible areas that make transmitting power difficult. Thus, it is essential to select the ideal cable type for applications in these industries.
Here are some specific considerations for wind turbine cables:
Enhanced mechanical properties: Wind turbine towers can be up to a few hundred feet tall. These heights affect cable length, so selecting cables with higher tensile strength is important. Cables should also have good torsional attributes and resist oil and flame.
Insulation: Harsh environmental conditions around wind farms often call for specific insulation. Insulated wires offer protection against voltage stresses, can operate over a wide temperature range, and better withstand mechanical abuse to the wire such as abrasion and bending.
Conductor: Both size and material of the conductor are integral considerations for wind turbine cables. Aluminum cables are increasingly replacing copper cables as tower and base components because aluminum is cheaper and 60% lighter.
The solar power industry also requires high-performance cables. When selecting the best type of solar power cables, consider these factors:
Type: There are several types of solar wires, and each is best suited to a specific function. For example, single-wire cables are best for domestic electrical applications. Other types include triple-wire or five-wire cables, which work better for large-scale operations.
Rating: A rating chart shows how many amps a cable can safely handle. Higher ratings ensure fewer voltage drops and a reduced chance of overheating.
Conductor size: The size of a conductor is defined by conductor cross-sectional area, not diameter. Thicker cables can transmit higher currents and voltages.
Length: Proper cable length also reduces voltage drop and maintains safe transmission.
