Photovoltaic (PV) Wire
PV wire is a single conductor, sunlight-resistant wire rated 90ºC wet or dry for interconnection wiring of grounded and ungrounded photovoltaic power systems
The National Electrical Code (NEC) rates the cables in the United States, while the Canadian Electric Code (CEC) rates them in Canada. PV wire conductors are made of copper or aluminum.

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.
Solar Cables and Accessories
At American Wire Group, we specialize in cables, wires, and accessories for renewable energy applications and other utilities. Learn more about our products below.
We offer fiber optic cables in single-mode and multimode varieties. These RS485 twisted copper wires are protected by a single jacket, double jacket, single armor/single jacket, double armor/double jacket, or fiber in duct option. It can be used as optical ground wire (OPGW), with OPGW hardware included.
Electrical wires ensure circuits run smoothly by safely discharging excess electricity. Our bare copper and copper-clad steel wires are designed to achieve this goal.
Medium Voltage Power Cables
Our medium voltage power cables range from 5 kV to 46 kV and come with an LLDPE or XLPE jacket. We offer copper tape, concentric neutral wires, or flat straps. Insulation options include:
- TR-XLPE insulation, MV-90 or MV-105
- EPR insulation, MV-90 or MV-105
Transmission & Distribtuion Wire & Cable
We provide overhead bare or covered transmission wires such as ACSR or AAAC.
Wire & Cable System Accessories
We offer the following wire and cable system accessories:
- Elbow arresters
- Sectionalizing cabinets

When selecting quality cables for your project, it is important to understand the differences between high-, medium-, and low-voltage cables. Each offers unique benefits for different applications and industries.
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.
