Eletric Cables of Different Voltage Classes

Introduction​​

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.

Description of ZMS Cable Products

ZMS electric wire company is a well-known manufacturer in Cables of different voltage levels. No matter what voltage level or type of cable you need, we can provide a customized cable solution based on your application needs.
Now today, there is always some ambiguity in the range of voltage levels for Voltage Cables. It depends on the country, as well as the standards-appointed bodies.

Low Voltage Cable 0.6/1KV or Below

Aerial bundled cable is an overhead line with aluminum core, aluminum alloy core or copper core as conductor and PVC / XLPE / HEPE as insulation. Applicable to overhead power line with a voltage level of 0.6 / 1KV and below. Its simple structure, convenient installation and maintenance, low cost and large transmission capacity are widely used in power transmission and distribution lines of various voltage levels. At the same time, it also has certain anti-corrosion ability, and it is also used in coastal areas of places with special geographical features.

ABC cable(Aerial Bundled Cable)---voltage level 0.6 / 1kv

XLPE insulated armored power cable has higher electrical strength, mechanical strength, resistance to aging, environmental stress, and chemical resistance. It has a simple structure and high operating performance, and can be placed for a long time without being restricted by drops. It is suitable for power transmission, construction, factory, communication and other fields. It can completely replace oil-impregnated paper insulated power cables and partially replace PVC insulated power cables.

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.
