In the solar engineering environment, tin-plated copper photovoltaic cable is often regarded as the first place to lay solar energy. Therefore, the advantages of tin-plated copper photovoltaic cable are undeniable.
What is tinned copper?
In short, tinned copper is copper coated with a base tin layer, such as more commonly known as tin solder. Sounds simple, but it doesn't stop there. Copper itself has many beneficial properties that make it very popular, but it also has drawbacks. This is where tin plating comes into play. Tin plating enhances the natural properties of copper and makes it better resistant to moisture, high temperatures and humid environments, which is why it is used in high-quality photovoltaic cables.
What are the advantages of photovoltaic cable tinned copper than bare copper
The use of photovoltaic cables with tinned copper is a simple and effective way to prevent the conductors from tarnishing or being oxidized.
Reasons for choosing tinned copper core wire for photovoltaic cable
The service life of 12AWG tinned copper PV cables is ten times longer than that of similar 12AWG bare copper cables. The tin corrosion resistant mesh does not oxidize the coating, so it helps to protect the copper inside the PV cable core, which can avoid additional wear and tear, thus extending the service life of the PV cable. This is especially important when the operating temperature of the PV wire exceeds 100 degrees Celsius. At higher temperatures, the copper corrosion resistance of PV cables decreases, so tin coatings are valuable for protecting PV wires in this state. Tinned copper is also ideal for use in any outdoor environment. This is the reason why it is chosen when manufacturing photovoltaic cables.。
Why is copper tinned?
Copper has good electrical conductivity and is quite resistant to corrosion. These facts coupled with its durability make it an ideal choice for electrical applications. Problems arise when copper is used in humid environments or areas of high humidity, where it corrodes and weakens more rapidly. This is prevented by tinned copper plating.
