What is cable carrying capacity

At present, there are many cable brands on the market. Because the production process of cable manufacturing is relatively simple, the capital investment is not big, which belongs to the "short and fast" project, consumers lack enough knowledge of the formal products, so some manufacturers have played the "edge ball". So in the face of a wide range of cable products, in the end how to choose to meet the standards, make people both assured and satisfied with the cable?

Cable carrying capacity refers to the power flow through a cable line during the transmission of electric energy. Under the condition of thermal stability, when the cable conductor reaches the long-term allowable operating temperature, the cable carrying capacity is called the long-term allowable capacity of the cable.

Cables are used to transport electricity, and to transport electricity, a current must flow through the line, and the more current the line passes through, the more power is transferred. The carrying capacity refers to the electrical capacity transmitted by the line conductor. Concrete each kind of specification of traverse allowable carrying capacity, our country standard has the regulation. When used, the load current required by the load must be less than the long-term allowable carrying capacity of the wire in the air. For example, a copper core of 25 square millimeters has a long-term allowable carrying capacity of 105A in the air. When your main equipment is running, the running current can only be less than or equal to 105A, and never greater than 105A.

We remember not to choose too low price cable, because many fires are caused by the use of poor quality cable. Install some general cables that do not have fire protection functions, that is to bury the hidden danger of an accident for your house. I hope these suggestions can help you choose the right cable and add a guarantee for your house.
