Top Metallic Sheated Cable for Trading

To protect the cables from environmental factors and mechanical shocks, they are covered with one or more layers (sheaths) of material (copper, lead, steel), plastic paper, especially PVC. Cables are divided into types according to their outer layers. There are many sellers who sell the highest quality metallic sheated cableto traders because this product is very thriving.

What Is Sheathed Cable Used For?

What Is Sheathed Cable Used For? Insulation of the good metallic sheated cable is due to the fact that because the cable is installed underground, it does not connect the conductor to the ground and the voltage on the insulation body is zero. In the case of overhead wires, it is not necessary to mention the word voltage about the specifications of the wires, but in the case of ground cables, in addition to the technical specifications of the cable, including cross-section and type of insulation and material in terms of mechanical resistance, cable voltage must also be mentioned. It should be noted that it is one or more disciplines. Depending on the type of use, different materials are used to insulate electrical cables, the most important of which are papers impregnated with special oils, plastic materials and P.V.C (polyvinyl chloride) and various other materials. Also, because the ground cables are exposed to various mechanical pressures, they have protective parts such as metal strips, and to prevent water from penetrating into the cable, a lead sheath is placed on all the protective and insulating strips, and to protect this sheath from the layer. Gypsum is used.

Purpose of Metallic Sheath Used in Power Cable

 Purpose of Metallic Sheath Used in Power Cable Before explaining the types of metallic sheated cable connector and wires, we will explain the definition of wires and cables and the difference between the two. The conductor wire is surrounded by an insulating cover. The electrical behavior of the wire is like an ohmic resistor and has no inductive and capacitive properties. Wires and cables are the conductors of electrical energy to different points in the construction of which conductive metals are used to transmit electricity. Overhead power supply uses uncoated wires, so-called bare wires. Accordingly, a conductor with an insulated sheath is called a coated wire or insulated wire, and if one or more insulated conductors are placed inside a common sheath, a cable is formed. Electric energy is one of the types of energy that is used to obtain different energies due to the ease of transmission. Because the transmission of electrical energy over long distances causes great losses, so to transfer this vital energy, methods are adopted that minimize losses. For this purpose, after generating electricity, by high-voltage transformers, the voltage is reduced from about 20 kV to 63, 132 and 400 kV, and then it is transmitted by overhead wires. At the point of distribution of electrical energy, this voltage is again made available to consumers and subscribers in the required standardized sizes by step-down transformers. The distribution of electrical energy in industry can be done in two ways, one by overhead wires and the other by cable.

Metallic Sheated Cable for Exporting

Metallic Sheated Cable for Exporting Medium voltage sheathed cable types have a voltage range of 6 kV to 30 kV. These cables are produced in single copper and triple strands in copper and aluminum. Medium voltage cable is used to power commercial or residential buildings and industrial distribution circuits. high voltage cable High voltage cables have a voltage range of 63 kV to 132 kV and are produced in copper and aluminum. Also, the voltage of high voltage cables is in the range of 230 kV to 500 kV and in Iran at two levels of 230 kV and 400 kV in transmission lines. After several decades of development of high voltage transmission lines as well as high voltage transmission lines, today the use of underground high voltage cable in densely populated urban areas is justified.
