What are the advantages of copper core wires?
Copper core wires are also very common in our lives. Because of its prominent advantages, more people choose to use it. Today, I would like to take this opportunity to introduce the advantages of copper core wires. If you want to know, let's take a look.
Copper core wires are also very common in our daily lives. Because of their prominent advantages, they are widely used. Today, I will take this opportunity to introduce the advantages of copper core wires. If you want to know, let's take a look.
Before using copper core wires, there is a lot of basic information we need to understand, after all, there are many knowledge points involved. For example, the resistance of copper core wire is 1.68 times that of copper core cable. The casting rate of this product is 20≤40%, the casting rate of electroplated copper is greater than 30%, and the casting rate of aluminum alloy is only 18%. The allowable stress at room temperature is 7≤28% higher than that of aluminum, especially the stress difference at high temperature is very large. Another important point is that aluminum copper core wires are easy to crack when repeatedly bent, while copper is not easy to crack. In terms of elasticity index, copper is also about 1.7 times higher than aluminum. Due to its lower resistance, copper core cables with the same cross-section have a higher promised load current than aluminum core cables. Equally important is its small footprint. Various wires winding in the air are messy, affecting the visual effect and occupying a lot of space. Because the insulation distance between wires is relatively small, power cables can be buried in the ground, laid in tunnels or indoors, without the need to erect poles, etc., which can save a lot of space and will not damage the scenery wherever they go. And the product has high reliability. The protective layer of copper core wire can not only waterproof, but also block the corrosion of other impurities to the cable, which undoubtedly reduces the impact of climate and surrounding environment on it; its insulation layer ensures the power transmission of the cable, and also ensures the stability of power transmission.
There is still much room for improvement in the use of copper core wires. Through continuous improvement, its power capacity and voltage are getting larger and larger, which makes its use value gradually increase, and people's growing demand for it has also promoted its improvement speed to a certain extent. Therefore, once copper core wires are laid, the maintenance work is relatively less. Because the laying channel of power cables does not need to be exposed, the damage to it will be correspondingly reduced, and the maintenance of it is less than that of ordinary wires. Another important point is that its distributed capacitance is relatively large. The materials used for copper core wires are all highly conductive, and there are usually multiple conductive cores inside the cable. Compared with overhead lines with the same cross-section and unit length as copper core wires, power cables have higher power and larger capacity. It is not easy to be electrocuted when used. The conductive core of the power cable is wrapped with insulation layer, shielding layer and protective layer. Layer by layer protection and its laying method can slow down the aging speed of the line, the possibility of damage is relatively small, and the possibility of electric shock will also be correspondingly reduced.
After the introduction of the above content, we also know the advantages of copper core wires. Other information will be updated in the next issue. If you have time, you can consult at any time. Customer service personnel will help you answer any questions.
