Power Cables of Different Voltage Classes

We consider to according to different voltage levels, cables can be divided into low-voltage cables, medium-voltage cables, high-voltage cables, and ultra-high-voltage cables. Low-voltage cables are used to transmit power on output distribution lines that are fixedly laid at 50Hz AC and rated voltage is 3Kv and below. Medium voltage cables generally refer to power transmission lines with voltage levels above 3kv and below 35kv. The voltage level of High-voltage cables is 35kv to 220kv. Suitable for substation or overhead power transmission cables.

Classification of Voltage Levels

The general rated voltage of low voltage power cables is: 300 / 300V, 300 / 500V, 450 / 750V, 0.6 / 1KV, 1.8 / 3KV, etc.

Low Voltage Cables voltage level

The general rated voltage of medium voltage cables is 3.6 / 6KV, 6 / 10KV, 8.7 / 15KV, 12 / 20KV, 21 / 35KV, 26 / 35KV, etc.

Medium Voltage Cables voltage level

The general rated voltage of high voltage power cables is: 36 / 64KV, 48 / 66KV, 64 / 110, 66/120, 127 / 220KV, etc.

    Performance Analysis

    All voltage cables have different structural elements, they have different combinations of one or more conductors, insulation materials, sheaths, and armors. High-voltage cables and low-voltage cables differ in that they have an additional inner layer in the insulation jacket to control the electric field around the conductor. And the shielding layer of the conductor can surround each insulated conductor, which can balance the stress on the cable insulation layer, prevent it from interfering with external equipment, and prevent external electric or magnetic fields from entering the cable.
