Electrical wiring in buildings is the most important market for the copper industry. Electrical copper cables had been implemented ever since telegraphs and electromagnets were invented, where half of all copper mined is turned into wires and cable conductors.
We provide and offer a wide range of copper cables which is used in power generation, power transmission, power distribution, telecommunications, electronics circuitry, and countless types of electrical equipment. Copper is the most widely used conductor in many kinds of electrical wiring and has the lowest resistance to the flow of electricity of all non-precious metals.
TYPES OF CABLES
Flexible cables, or `continuous-flex` cables, are electrical cables specially designed to cope with the tight bending radii and physical stress associated with moving applications, such as inside cable carriers. Due to increasing demands within the field of automation technology in the 1980s, such as increasing loads, moving cables guided inside cable carriers often failed, although the cable carriers themselves did not. In extreme cases, failures caused by "corkscrews" and core ruptures brought entire production lines to a standstill, at high cost. As a result, specialized, highly flexible cables were developed with unique characteristics to differentiate them from standard designs. These are sometimes called “chain-suitable,” “high-flex,” or “continuous flex” cables. A higher level of flexibility means the service life of a cable inside a cable carrier can be greatly extended. A normal cable typically manages 50,000 cycles, but a dynamic cable can complete between one and three million cycles.
High Voltage Copper Cable
A high-voltage cable (HV cable) is a cable used for electric power transmission at high voltage. A cable includes a conductor and insulation, and is suitable for being run underground or underwater. This is in contrast to an overhead line, which does not have insulation. High-voltage cables of differing types have a variety of applications in instruments, ignition systems, and AC and DC power transmission. In all applications, the insulation of the cable must not deteriorate due to the high-voltage stress, ozone produced by electric discharges in air, or tracking. The cable system must prevent contact of the high-voltage conductor with other objects or persons, and must contain and control leakage current. Cable joints and terminals must be designed to control the high-voltage stress to prevent breakdown of the insulation. Often a high-voltage cable will have a metallic shield layer over the insulation, connected to the ground and designed to equalize the dielectric stress on the insulation layer. Segments of high-voltage cables High-voltage cables may be any length, with relatively short cables used in apparatus, longer cables run within buildings or as buried cables in an industrial plant or for power distribution, and the longest cables often run as submarine cables under the ocean for power transmission.

Steel wire armoured cable, commonly abbreviated as SWA, is a hard-wearing power cable designed for the supply of mains electricity. It is one of a number of armoured electrical cables – which include 11 kV Cable and 33 kV Cable – and is found in underground systems, power networks and cable ducting.
Tough rubber-sheathed cable is a type of cable which normally consists of a black outer sheath of rubber with several conductors inside. The rubber provides an abrasion-resistant, corrosion-resistant, waterproof, protective covering for an insulated electric cable. Though obsoleted for domestic use, it is used for flexible cables when greater mechanical toughness than PVC is required such as temporary electrical wiring at events where the cable is standardised as Cenelec code H07RN-F (H07 for short) The American National Electrical Code, for theater use, requires (article 520.68(A).1) cables to be "extra hard usage" rated, and such cable is generally known in the USA as SOOW cable. Cables meeting the SOOW spec can also be manufactured to be rated as H07RN-F, so-called "harmonised" cable, and such cable can be used both in the USA and Europe.
