FAQ: PV Wire and Electrical Cables


What is PV wire?

PV wire, or photovoltaic wire, is a specialized single-conductor wire used in solar power systems. It is designed to withstand the harsh environmental conditions that solar installations are exposed to, including UV radiation, moisture, and temperature fluctuations. PV wire is critical for connecting solar panels to the electrical grid or battery storage systems. 

What is PV wire made out of?

PV wire is typically made from copper or aluminum conductors coated with a durable, sunlight-resistant insulation. The insulation is often made of materials like XLPE (cross-linked polyethylene) or EPR (ethylene propylene rubber), which provide excellent durability, heat resistance, and flexibility. 

Who sells PV wire?

PV wire can be purchased from electrical supply stores, solar equipment suppliers, and online retailers. Suppliers like Titan WNC can provide a wide range of PV wire for any project as well as offering expert advice on the entire BOS system. 

Are all PV wires the same?

Not all PV wires are the same. They can vary in terms of conductor material (copper or aluminum), insulation type, voltage rating, and temperature rating. It is important to select PV wire that meets the specific requirements of your solar installation, including compatibility with other system components and compliance with local electrical codes.

How is fiber optic cable made?

Fiber optic cable is made by drawing glass or plastic fibers through a manufacturing process that ensures they are extremely thin and capable of transmitting light signals over long distances. These fibers are then coated with a protective layer, assembled into a core, and encased in a protective outer jacket. The manufacturing process involves precise control to ensure signal clarity and strength. 

What is USE-2 wire?

USE-2 wire, or Underground Service Entrance wire, is a type of electrical wire used for underground electrical service applications. It is designed to withstand direct burial in the ground and is highly resistant to moisture and sunlight. USE-2 wire typically features a thermoplastic insulation that provides durability and protection in harsh environments. 

Is bare copper wire expensive?

Bare copper wire can be relatively expensive due to the high cost of copper as a raw material. Prices fluctuate based on market conditions, but copper is generally more expensive than other conductive metals like aluminum. The price of bare copper wire reflects its excellent conductivity, durability, and widespread use in electrical applications. 

What is medium voltage cable used for?

Medium voltage cable is used for transmitting electrical power at voltages ranging from 1kV to 35kV. It is commonly used in power distribution networks, industrial applications, and renewable energy systems such as wind and solar farms. Medium voltage cables are designed to handle higher electrical loads and provide reliable performance in various environmental conditions.
