ZMS Cable Group products

Aluminium conductor power cable overhead has been widely used in power transmission lines and electricity distribution lines with various voltage levels. Overhead Line wires, whether bare conductors or insulated cables, provide an aerial route for the transmission and distribution of power. ZMS Cables supplies a comprehensive range of aluminum overhead conductor line wires AAC, AAAC, ACSR, and aerial bundled cables (ABC) for the aerial power cable.

PVC/XLPE copper power cables are used to transmit and distribute power in the power transmission and distribution system. It is generally applied to fields including power, construction, mines, metallurgy, petrochemical industry, and communication in the complete replacement of oil immersed paper insulated power cables and in partial replacement of PVC-insulated power cables. Here is the introduction of low voltage power cables, according to the cable classification, there are also high-voltage and medium-voltage cables.

Like other power cables, High voltage XLPE cables typically consist of one or three conductors, insulation, and a sheath structure. High Voltage Underground Wire Cables differ from low voltage cables in that they also have an inner layer within the insulation sheath to control the electric field around the conductors. For circuits running at relatively high voltages between conductors, the conductor sheaths can surround each insulated conductor. In this way, the electrical stresses on the cable insulation can be balanced and unnecessary losses in the cable can be reduced.

ACSR is mainly used for high voltage or extra high voltage overhead transmission. Because the main advantage of these conductors is their high tensile strength, they can be used for longer spans with fewer supports, saving installation and maintenance costs. Because of the larger diameter of ACSR conductors, higher transmission and distribution power can be obtained, thus providing a great advantage in high-voltage and ultra-high-voltage overhead lines.

High-voltage power cables are suitable for the primary distribution of electricity up to a maximum network voltage of 110 kV, and also where mechanical protection is provided by other means. The cables are triple extruded on modern catenary equipment in accordance with the latest IEC standards. The water barrier ensures that in the event of cable damage, the length of repair and associated work is kept to a minimum. These cables are equipped as standard with a high-density polyethylene sheath that combines abrasion resistance and flexibility. The range can be customized to meet specific project requirements where required.
