What materials are used for photovoltaic cables?

The main materials of photovoltaic cables include copper, aluminum, steel core aluminum, stainless steel, ferrite, and sheet metal. ‌‌

• Copper: Copper has good electrical and thermal conductivity, can withstand large current loads, and has a long service life, good stability, corrosion resistance, and oxidation resistance.
• Aluminum: Aluminum is lightweight and has good electrical conductivity, but its resistivity is higher than copper, making it suitable for cost sensitive projects.
• Steel core aluminum: Combining the advantages of steel core wire and aluminum wire, it has good strength and conductivity, and is suitable for projects that require bendability and flexibility.
• Stainless steel: It has excellent corrosion resistance, good durability, and is suitable for projects with harsh environments.
• Ferrite: a magnetic ceramic material suitable for high-frequency environments and large power equipment.
• Sheet metal: Lightweight and affordable, suitable for simple projects or temporary on-site use.
