What We Often Hear About The Wire And Cable Capacity Is

Whenever we often need to use wire and cable in the actual work, but there are places where the size of the power varies, we often hear that the difference in the load capacity of wire and cable will directly affect the transmission of electricity, then we will talk about the following wire and cable load capacity it!

Wire and cable capacity rating is what

Cable load capacity refers to the cable line in the transmission of electrical energy to withstand the stable heat, and is a long time to bear and have a stable work of the cable load flow is called the load capacity.

The current-carrying capacity is the maximum current (in amperes or, more simply, in amperes) that an insulated conductor can safely carry without exceeding its insulation and sheath temperature limits. As the amount of current flowing through a conductor increases, the amount of heat generated in the conductor increases. The heat generated in the conductor must escape into the environment. If the heat does not escape, the temperature of the conductor will continue to rise until the cable exceeds its rated temperature and the cable will deteriorate.

The current carrying capacity of a cable should equal or exceed the maximum current the cable is expected to carry during its service life, but not exceed its temperature rating. The temperature rating depends on the heat resistance of the materials used for the cable insulation and sheathing. The higher the heat resistance of a material, the less likely it is to deteriorate at higher temperatures. The most common conductor temperature rating is 90°C, but for some special applications of wire and cable, the conductor temperature rating can be as low as 60°C or as high as 1,200°C. Although the conductor temperature plays an important role in determining the current carrying capacity rating.

Industrial Examples

Temperature ratings and ambient temperatures play an important role in the current-carrying ratings of solar farms.

Photovoltaic (PV) wire is used as an interconnection wire on solar panels in grounded or ungrounded systems.

PV systems, including PV modules, PV power circuits and PV output circuits, can generate output currents above the rated short-circuit current for more than three hours.

Due to the high current flow and temperature, the load capacity of the PV wire is calculated to be 125% of the sum of the rated short-circuit currents of the paralleled modules.

There are many factors that influence proper conductor and cable selection, and incorrect product selection can be costly.
