4mm2 Pv Cable
This 4mm² PV cable is a high-performance cable designed for solar systems and is suitable for solar power generation projects of all sizes. It uses high-quality copper conductors to provide excellent conductivity and low resistance to ensure efficient power transmission. Its insulation and sheath materials use weather-resistant cross-linked polyethylene (XLPE) or thermoplastic elastomer (TPE), which has excellent resistance to UV, high and low temperatures, and abrasion. The cable is rated at 1000V and meets the needs of medium and high voltage solar systems. The flexible design makes it easy to install and wire, especially suitable for complex installation environments. It complies with international standards (such as IEC 62930, UL 4703), and has undergone strict quality control and testing to ensure long-term and reliable use. Whether it is a home rooftop installation or a large solar farm, 4mm² PV cable is your ideal choice to help you achieve efficient and safe solar power generation.
Conductor material:
High-quality copper conductor: High-purity oxygen-free copper (Oxygen-Free Copper, OFC) or tinned copper is used to provide excellent conductivity, low resistance, and ensure efficient power transmission. Tinned copper can also enhance corrosion resistance and is suitable for long-term use in various environmental conditions.
Insulation material:
Cross-linked polyethylene (XLPE): The insulation layer usually uses XLPE, which has excellent heat resistance and can withstand high temperature environments (usually up to 90°C). It can also maintain good flexibility and electrical insulation performance at low temperatures (usually up to -40°C).
Thermoplastic elastomer (TPE): Some cables use TPE as an insulation material. TPE materials have good wear resistance, UV resistance and chemical corrosion resistance, and have high flexibility and elasticity.
Waterproof and moisture-proof performance of cables
Sealing design:
The design of photovoltaic cables usually takes into account the sealing of joints and ports to prevent moisture from entering the cable through the joints. High-quality photovoltaic cables will use sealants and waterproof joints at the joints to ensure the waterproofness of the connection parts.
The installation of photovoltaic cables needs to meet conditions, including following relevant electrical specifications and standards, being installed by professionals, proper wiring and connection, taking necessary protective measures to prevent the cables from being damaged by the external environment and objects, and ensuring the safety and stability of the system. At the same time, it is necessary to avoid exposing the cables to high temperatures or near fire sources, and avoid crossing with other electrical equipment to reduce the impact of electromagnetic interference. Regular inspection and maintenance are also necessary to ensure the reliable operation of the cables.
Types of photovoltaic cables used in solar power generation systems
Home rooftop photovoltaic system: used to connect the power transmission between solar panels and inverters.
Commercial and industrial photovoltaic projects: solar power generation systems suitable for large commercial buildings, factories and warehouses.
Solar farms: large-scale solar power generation sites used to connect hundreds or even thousands of solar panels.
Outdoor solar lights: used for power transmission in outdoor lighting systems such as solar street lights and solar garden lights.
Solar water pump system: used to connect the circuit between solar panels and water pumps in solar water pump systems.
Solar carport: used to support the connection between solar panels installed on solar carports and the power grid.
Remote area power supply: photovoltaic cables are used to build solar microgrid systems in remote areas or places without traditional power supply.
