Copper cable - Features, Specifications and Operation

What is the copper cable?

This category includes power multicore cables for different purposes.Given that there are now a myriad of species, which are produced both by the industry and for the nation-wide standards, only exemplary alphanumeric marking products used in practice.Simply put, it is accepted the technical designation of cables with specific parameters for the manufacture of which materials are used respective guests.

What is standard cable design?It is one or, more often, more insulated conductors which are enclosed in a sealed envelope.It can be aluminum, lead, rubber or plastic.Sometimes, depending on the conditions of use, the product is coated with a layer of armored steel strips or wires of various sections.

copper cable - types

products At present, there are several kinds of cables that are distinguished by application. Power - used in construction line, the main purpose of which is the transmission and distribution of electricity in lighting and power installations.Industry produces samples with aluminum and copper conductors.

used as insulation paper, polyethylene, PVC, rubber and other materials.Armoured coating made of lead, aluminum, rubber or plastic. Control cables - used to supply power signals to a variety of low voltage electrical devices and the creation of special control circuits.Equipped with copper or aluminum conductors up to 10 mm2.

The automated control systems are commonly used products with copper conductors in a plastic sheath, shielded coating to protect against electromagnetic interference.Weight of copper cable depends on the number of veins, as well as their cross-section.

widely used in communications, found special cables by means of which the transmission of signals.This type is divided into high-frequency cables and long-distance low frequency for local use in the local lines.

Ensuring communication between wireless devices is carried out using cables coaxial design with a central copper wire coated with Teflon or polyethylene.The upper insulating layer made of the same materials.

load copper cable and other aspects of the operation

in further detail the power products and their applications, for which the resistivity of copper cable is considered optimal, since this figure is mainly dependent on the material and operating temperature.According to the instructions of controlling bodies, as the wiring in residential and commercial buildings, it is recommended to use a multi-conductor cables from copper.

greatest demand among builders use products VVG mark.This type of wiring is a product with double PVC insulation.Depending on the total cross-section it can be applied in areas where the load on the copper wire is from 0.6 to 6 kV.By the way, to check the resistance of copper cable in the home appliance is possible by means SmartClass ADSL, which is intended to measure various parameters of the wiring.

also very popular copper cable with rubber insulation type KG.Due to the presence within the plurality of copper wires, it differs a great flexibility.To use this type of wiring in the permafrost into the insulation KG introduced special additives.

and completes the list of armored cable VBbShv provided with a double PVC insulated and protected by two layers of metal tape.This type is mainly used for lines, laid in the ground, in tunnels and in air.Due to the graphite crumbs, which is part of the insulation, it is quite resistant to fire.
