Weather resistance and UV resistance

The outer sheath material of photovoltaic cables usually adopts excellent weather resistance materials, which can withstand long-term direct sunlight, and is not easy to age or crack, ensuring the long-term operation of the system.

High temperature and cold resistance

Photovoltaic cables are suitable for extreme temperature environments. The operating temperature range is generally -40°C to 90°C. Some high-temperature photovoltaic cables can even withstand 125°C and are still reliable in extreme climates.

High flame retardancy

Photovoltaic cable materials have extremely high flame retardancy. Even if a fire occurs, it can effectively delay the spread of the fire and increase the safety of the system.

Good insulation and moisture resistance

The insulation layer material of the cable is waterproof and corrosion-resistant, which can avoid the influence of rain and humid environment on the cable and prevent the occurrence of leakage.

Low power consumption and high efficiency

Photovoltaic cables have a low resistance design to reduce power loss, maximize the power generation efficiency of the system, and improve the overall efficiency of the photovoltaic system.

Solar panel connection

Photovoltaic cables are widely used to connect equipment such as solar panels and photovoltaic generators to ensure efficient and safe transmission of electricity converted from solar power generation to the system.

Electrical wiring of photovoltaic power generation systems

In rooftop and ground photovoltaic systems, photovoltaic cables are used for electrical wiring of the entire system, connecting various components and ensuring stable transmission, which is particularly suitable for outdoor environments of solar energy.

Installation of grid-connected and off-grid systems

In grid-connected and off-grid systems, photovoltaic cables are used for power transmission from photovoltaic modules to junction boxes and then to photovoltaic generators or battery packs, providing efficient power transmission for multiple photovoltaic systems.

Photovoltaic and water-based photovoltaic projects

Photovoltaic cables are widely used in agricultural and water-based photovoltaic projects. The agricultural anti-corrosion and waterproof performance formula is suitable for areas with high humidity to ensure system stability.

Photovoltaic systems in remote areas and remote areas

Photovoltaic cables are suitable for operation in remote or extreme environments, and can provide reliable cable connection solutions for power supply in remote areas and remote areas.
