Chinese high quality UL 4703 PV wire manufacturer Jul 01,2022

Photovoltaic wire, also known as PV wire, is a single-conductor wire used to connect the panels of a photovoltaic electric energy system. PV systems, or solar panels, are electric-power production systems that capture sunlight in order to produce electricity through an energy conversion process. Electricity is produced at the panel and wiring is needed to convey the electrical energy back to a collection point or piece of equipment. Photovoltaic wire is a specific kind of wire created for PV applications.


PV wire needs to be carefully engineered to ensure it is safe and consistent in a wide range of demanding outdoor applications, including:

Solar farms. Also known as photovoltaic power stations, these large solar arrays provide energy to the public power grid.

Residential solar. Installing solar roof panels can reduce annual energy costs and increase resale home values.

Recreational applications. Solar systems are commonly used for ‘off-grid’ recreational properties to supplement or even replace generator power. Solar power is also used extensively for RVs, motorhomes, and sailboats.

Solar for business. There are many commercial and industrial applications for solar power.


The photovoltaic market is a very specific market. Various national regulations are to be taken into account. In the United States, PV wire is a single-conductor product that meets the requirements of UL 4703 Standard for Photovoltaic Wire.


Engineered for safety and durability, SUNKEAN’s PV wire is a single conductor wire with a cross-linked polyethylene (XLPO) insulation. This insulation is rated at either 600V or 1,000/2,000V, and is VW-1 flame retardant, and weather, UV, ozone, and damp heat resistant. The conductor wire is made from strand tinned copper. Enhancing its resistance to high temperatures and moisture.


UL4703 PV wire


Our UL4703 PV wire is also available in a wide range of gauges (from #4/0 to #14), and a maximum continuous operating temperature between -40°C and 105°C. It has the following advantages:

(1)E-beam cross-linked compounds;

(2)High resistance against UV ozone and hydrolysis;

(3)High temperature resistance, materials will not melt or flow;

(4)Flexibility under cold conditions;

(5)Long useable life expected usable life over 25 years(90℃) ;

(6)Application to all common connectors.
