Copper cables are used as one of the main drivers in energy transmission, and high electrical conductivity is an important characteristic of copper drivers. Copper itself has an excellent electrical conductivity. This property allows copper cables to effectively transmit energy and reduce energy losses. The Copper cable conductivity directly influences the efficiency and reliability of the energy transmission. Copper cable current transport capacity, as for her, is one of the most important parameters to measure their energy transmission capacity.
Definition of current transport capacity
Copper cable transport capacity of a driver or an isolated cable is the maximum current (ampères) which can be transported continuously without exceeding its nominal temperature. It is also called current transport capacity.
The current transport capacity is the maximum current that a driver or a cable can transport continuously without exceeding its nominal temperature.
The current copper cable transport capacity is crucial in the cable operating process. To calculate the current transport capacity of a cable, several factors must be taken into account. Here we will examine the factors that influence the transport capacity of the current.
Factors Affectant la Capacity for Transport of Courant
Copper cables of different specifications have a current transport capacity of different copper cables. Even if the cable parameters are identical, The current transport capacity also varies depending on the environment in which it is downloaded. The factors that influence the current transport capacity include driver's material, The driver's section, the insulation material, etc. Of course, Besides the cable itself, Other factors influence the copper cable transport capacity.
Conductor material
The driver's driver material is generally copper or aluminum, and the conductivity and the resistivity of the different materials are different, so that the current transport capacity is also different. If the conductivity of the driver is good, If the resistance is low, The capacity of the cable will be all the greater. Copper is always present in printed circuits, Electrical instrumentation equipment and major energy production projects. Indeed, Among the commonly used metal conductors, Copper has better electrical conductivity. On the other hand, copper cables have a higher copper cable transport capacity than Aluminum cables.
Driver section surface
The larger the cable driver's surface of the driver's section, The more important the current it can transport. Therefore, A cable whose section is larger also has higher current transport capacity.
Insulation material
Cable insulation material has a significant impact on heat resistance and cable electrical performance. Different insulation materials have different heat resistance and can therefore support higher currents. Generally speaking, A good heat resistant insulation material can increase cable current transport capacity.
Installation method
The way the cable is installed also has an impact on current copper cable transport capacity. It mainly depends on the temperature of the indirect effect. For example, If the cable is buried in a confined space and heat dissipation is low, cable current transport capacity will be lower, in order to guarantee security.
Calculation from Capacity for Transport of Courant
The current copper cable transport capacity can be calculated using the next basic formula :
Load capacity = I x k/s
Where I is the current, K is the conductivity of the driver and s is the surface of the driver's section.
According to the formula, We must determine three parameters. We must determine three parameters. The current, conductivity and transverse section. The driver's section is determined before cable manufacturing.
There is a narrow correlation between the maximum current that the cable must support and the size of the cable section. The cables supporting higher currents require an increase in the size of the cable section.
Of course, It is a simplified algorithm. A precise calculation of the cable current transport capacity must also take into account the driver resistance per unit of length, of the ad hoc loss of insulation per unit of length, thermal resistance between the driver and the sheath, as well as other factors.

Cooking cable cable transport capacity is an important parameter when selecting cables. It is influenced by various factors. These include the driver's section, ambient temperature, ventilation, etc. Calculation of cable current transport capacity is an important element in the electrical system. Calculation of cable current transport capacity is an important part of the electrical system.
