4 square meter photovoltaic line

4 square meter photovoltaic line is a widely used basic power transmission cable in photovoltaic power generation systems. It is specially designed for connecting photovoltaic modules in series, modules and combiner boxes in close proximity. It is the preferred matching wire for household distributed photovoltaic power stations, small photovoltaic panel groups, portable photovoltaic equipment and other scenarios, suitable for various needs of low-power photovoltaic power transmission, and all meet the long-term stable operation requirements of photovoltaic systems under various outdoor working conditions.

This specification of photovoltaic line uses high-purity tin plated copper as the conductor core, with a fine wire diameter that meets the national standard of 4 square meters. The conductor is made through technical twisting process, which not only protects the excellent current carrying capacity in the adapted scenario, but also achieves low resistance power transmission, which can effectively reduce power loss during short distance transmission and improve the power generation utilization rate of the photovoltaic system; The material characteristics of tin plated copper core enable cables to have excellent oxidation and corrosion resistance, which can resist environmental erosion such as outdoor humidity, dust, and slight salt spray, prevent conductor oxidation and aging, and effectively extend the actual service life of cables.

The insulation layer and sheath layer of the cable are made of photovoltaic one-to-one weather resistant modified polymer materials, providing targeted innovative services for UV resistance, high and low temperature resistance. It can adapt to extreme outdoor temperature environments ranging from -40 ℃ to 90 ℃, and is not afraid of long-term tests such as sun, rain, wind, frost, snow, and freezing. At the same time, it has good aging resistance, crack resistance, and good acidity and alkalinity, and can operate stably in various installation scenarios such as roofs, brackets, and walls; The protective layer has both wear resistance (based on actual reports) and resistance to slight mechanical impacts, and can effectively resist friction, bumps, and minor external damage during installation, as well as daily use. It constructs a solid protective barrier for the internal conductor and protects the stability of power transmission.

The 4-square-meter photovoltaic line not only protects performance, but also considers safety and construction convenience. The insulation and sheath layers comply with national flame retardant standards and have the flame retardant characteristic of self extinguishing in case of fire. It can effectively reduce the electrical fire risk of photovoltaic systems and improve the electrical safety of power stations and small photovoltaic equipment in all aspects; The wire body is compact and has excellent flexibility, with good bending ability. It can be wired and docked without the need for one-on-one tools, and can be flexibly installed in narrow spaces such as photovoltaic module gaps and bracket gaps. It is well adapted to the installation needs of densely arranged components, greatly simplifying the on-site construction process and improving construction efficiency.

All performance indicators of the product strictly follow the relevant national standards for photovoltaic cables and electrical safety regulations for design and production. After multiple rigorous tests for voltage resistance, weather resistance, flame retardancy, current carrying capacity, etc., the standardization of specifications is good, and it can be well adapted to the wiring ports of various photovoltaic modules, small combiner boxes and other equipment on the market. It has strong universality and provides stable and excellent power transmission protection for the long-term, safe and effective operation of household photovoltaics, small photovoltaic systems and portable photovoltaic equipment.
