Why UL 4703 photovoltaic cable suitable for the installation of solar panel?

Veteran electricians know that you can't install a solar panel without wiring, and all solar panels need wiring, whether monocrystalline, polycrystalline, or thin film. You will need to wire the solar panels and other components to each other. Happily , UL 4703 photovoltaic wire is perfect for solar panel installations.

What is the definition of UL 4703 photovoltaic wire?

UL 4703 wire is a photovoltaic wire designed for solar panel installations. Like all wires, it acts as a conductive path for electricity. However, in the United States UL 4703 photovoltaic wire is designed for solar panel installation. If you plan to install solar panels, you should use photovoltaic wire.

Underwriters Laboratories (UL) 4703 is the specification for photovoltaic wires. It lists the design rules for photovoltaic wires. For example, photovoltaic wires must be made of copper, copper-clad aluminum or aluminum. It must also reach 90 degrees Celsius when wet and 105 degrees Celsius when dry.

Features of UL 4703 Photovoltaic Wires

Because it is designed for solar panel installation, the UL 4703 photovoltaic wire is resistant to sunlight. There are many different types of wires. Some of them may degrade when exposed to sunlight.

Sunlight can cause the jacket to degrade, making it brittle and prone to cracking. UL 4703 photovoltaic wire provides a high level of sun protection. Even when exposed to direct sunlight, it will remain intact while retaining its enclosed conductors.

UL 4703 PV wire is fire rated. It does not contain any combustible materials. UL 4703 photovoltaic wire consists of metallic conductors wrapped in a thick plastic-like jacket or layer or insulation. Therefore, it is fire resistant. The fire-resistant properties of UL 4703 photovoltaic wire make it safe for residential solar panel installations.

UL 4703PV wire has a thicker jacket or insulation than other types of wire. A jacket or insulating layer surrounds the conductive core. And because it's thick, it protects the conductive core from damage.

Perhaps you might notice that UL 4703 photovoltaic wire is more flexible than other types of wire. When installing the solar panel, you can easily bend it. Bending UL 4703 photovoltaic wire will not damage its conductive core. With its flexible features, you can easily connect your solar panels with UL 4703 photovoltaic wires.

Summarize the above

You shouldn't just use any type of wire when installing solar panels. While other types of wiring may work, UL 4703 PV wiring is no substitute. Because UL 4703 photovoltaic wire is resistant to sunlight, fireproof, and flexible, it is a rare wire in the industry.

Well, the above is the introduction of " Why is UL 4703 photovoltaic cable very suitable for the installation of solar panels? ", I hope it can help everyone! It is recommended to continue to pay attention to JZD Cable to learn more about wire and cable information.
