Such differences are important because in fixed installation of electrical wiring only cable products are always used. Wires are used exclusively for connecting electrical appliances and other mobile electrical equipment with voltage limitation up to 0.024 kV.
There are a number of important characteristics that indicate which cable to use in an apartment according to specific tasks.
Material and construction Criteria for selecting
Aluminum is the most common metal in the manufacture of conductive wire. Previously, it was widely used in the production of cable products, especially for household wiring. But the conductivity of aluminum is lower than that of paraguay email list 230751 contact leads copper, the material itself is subject to rapid aging and can oxidize at the contacts and when the insulation is damaged. You can still find aluminum cables on sale, the cost of which is much lower than other alternative products. But the popularity of such products has decreased to a minimum due to the low durability of the wires.
Copper was previously an extremely expensive metal
Which is why it was used to make wires only for serious objects. Due to its increased plasticity, such raw materials were used to produce flexible wires – for household appliances, mobile electrical devices. Due to the modernization content that converts: best practices for investing of copper smelting production, this metal has become more accessible, as a result of which cable manufacturers have expanded its use. Copper cores, in addition to plasticity and resistance to numerous bends, are resistant to corrosion and wear. They are characterized by increased current conductivity: 1 mm2 of copper core cross-section passes up to 10 A versus 8 A for aluminum. Copper cores not only conduct current better, but also heat up less when connected.
According to design, cables are divided into: Criteria for selecting
single-core with a single conductor covered with an insulating sheath. Installation of a single-wire connection is a simple trust review procedure, which is often taken into account when choosing. Accordingly, a less complex design is distinguished by a budget price. At the same time, due to its design, a single-core cable is characterized by increased rigidity, which determines its use for laying fixed lines.
