What Are The Differences Between High Voltage Cables And Low Voltage Cables?

The difference between high-voltage cables and low-voltage cables is mainly reflected in the following aspects:

Voltage level: High voltage cables are usually used to transport high voltage electrical energy, the voltage level is generally above 110 kV, such as 500 kV or 1000 kV; The low-voltage cable is used to transport low-voltage electrical energy, and the voltage level is generally below 1000 volts.

Transmission capacity and structure: High-voltage cable due to withstand higher voltage, can transmit more electric energy, suitable for long-distance transmission; The low-voltage cable is mainly used for internal power distribution in buildings, factories, homes and other places, and the transmission capacity is low.

Design and manufacturing requirements: high-voltage cable design, manufacturing and installation requirements are more stringent and complex, need to consider electric field distribution, insulation strength, high temperature resistance and other factors; The manufacture and installation of low-voltage cables are relatively simple, and their physical structure and material selection are more common.

Application range and use environment: High voltage cable is mainly used in large power plants, substations, power transmission lines and other places, for long-distance transmission; The low-voltage cable is widely used in construction, industry, transportation and other fields, for indoor power distribution, lighting, power equipment and so on.

Safety: High voltage cable in the operation process there is a large security risk, once failure or leakage, may cause serious accidents; The safety risk of low-voltage cables is relatively small, the maintenance is relatively simple, and can generally be handled by ordinary electricians.
