What are the materials, structures, characteristics and advantages of photovoltaic cables?

Product materials

Conductor: tinned copper wire

Sheath material: XLPE (also known as: cross-linked polyethylene) is an insulating material.

Structure

1. Generally pure copper or tinned copper core conductor is used

2. Two types of inner insulation and outer insulation sheath

Features

1. Small size and light weight, energy saving and environmental protection;

2. Good mechanical properties and chemical stability, large current carrying capacity;

3. Smaller size, light weight and low cost than other similar cables;

4. Good corrosion resistance, high temperature resistance, acid and alkali resistance, wear resistance, no erosion by wet water, can be shielded in corrosive environments, good anti-aging performance and better service life;

5. Low cost, free to use in environments with sewage, rainwater, ultraviolet rays or other highly corrosive media such as acids and alkalis.

The characteristics of photovoltaic cables are simple in structure. The irradiated polyolefin insulation material used has excellent heat resistance, cold resistance, oil resistance, and UV resistance. It can be used in harsh environmental conditions. At the same time, it has a certain tensile strength and can meet the needs of photovoltaic power generation in the new era.

Advantages

1. Corrosion resistance: The conductor uses tinned soft copper wire, which has good corrosion resistance;

2. Cold resistance: The insulation uses cold-resistant low-smoke halogen-free material, which can withstand -40℃, and has good cold resistance;

3. High temperature resistance: The sheath uses high temperature resistant low-smoke halogen-free material, with a temperature resistance grade of up to 120℃ and excellent high temperature resistance;

4. Other properties: After irradiation, the insulation sheath of the photovoltaic cable has the characteristics of anti-ultraviolet radiation, oil resistance, and long life.
