Conductor Material and Structure: Usually made of high - purity oxygen - free copper or tinned copper. It is composed of 19 strands of copper wires, which can ensure good electrical conductivity and flexibility1.

Insulation and Sheath Materials: The insulation material is often cross - linked polyethylene (XLPE), which has excellent electrical properties, low dielectric loss, and small capacitance4. The sheath is usually made of UV - resistant, flame - retardant thermoplastic elastomer (TPE) or XLPE, with the characteristics of UV resistance, oil resistance, ozone resistance, and abrasion resistance, which can adapt to harsh outdoor environments3.

Electrical Parameters: The rated voltage is 1000V DC, and it has a certain current - carrying capacity. Generally, the current - carrying capacity of #10 solar wire can reach about 30 - 40A, but the specific value varies according to different standards and manufacturers' specifications. Its DC resistance is relatively low, which can minimize power loss during power transmission.

Temperature Range and Service Life: It can usually work normally in the temperature range of - 40°C to + 90°C4. After special design and treatment, it can maintain good performance under long - term outdoor exposure, and the service life can reach 25 years or more4.

Certification Standards: Usually comply with international standards such as IEC 62930 and TÜV EN 50618, and may also have UL 4703 and other certifications, to ensure that the product meets the safety and performance requirements of solar power systems1.

Application Scenarios: Mainly used for the connection between solar panels, the connection from solar panels to inverters, and other parts of solar power generation systems, especially suitable for residential rooftop solar power systems and small - scale commercial solar power projects
