What Is the Difference Between Solar Cables and Ordinary Cables?

There are significant differences between solar cables and ordinary cables in terms of application scenarios, structures and materials, and performance characteristics. Therefore, when selecting cables, comprehensive considerations should be made based on specific application requirements and working environment to ensure the performance, safety and reliability of the cable. The following is a detailed explanation of the difference between the two:

1. Application scenarios

Solar Cables: Specifically designed for use in photovoltaic systems, i.e. solar electric systems. Suitable for connections between solar panels, connections between batteries and inverters, etc.

Ordinary cables: widely used in various types of ordinary electrical equipment and circuits. It is commonly used for power transmission and distribution in homes, offices, factories and other places.

2. Structure and materials

Solar cable:

Conductor: Usually copper conductor or tinned copper conductor is used to improve conductivity and corrosion resistance.

Insulation layer: Use radiation cross-linked polyolefin material, which has excellent heat resistance, cold resistance, oil resistance, acid and alkali resistance, UV resistance and other properties.

Sheath: Also made of irradiation cross-linked polyolefin material, which provides additional protection and enhances the durability of the cable.

Ordinary cable:

Conductors: Also use copper conductors or tinned copper conductors.

Insulation layer: Polyvinyl chloride (PVC) or cross-linked polyethylene (XLPE) and other materials are often used, and their performance is relatively ordinary.

Sheath: Generally made of polyvinyl chloride (PVC) material, providing basic protection.

3. Performance characteristics

Solar cable: resistant to high temperature, cold, oil, acid, alkali and salt, and UV rays. Flame retardant and environmentally friendly, complying with relevant safety standards. It has a long service life and can maintain stable performance in harsh outdoor environments.

Ordinary cable: only suitable for power transmission and distribution in ordinary environments. The performance is relatively limited and may degrade in harsh environments such as high temperature, cold, and humidity.
