Electric(elektroservis) Wiring

Electric(elektroservis) wiring is a means by which a consumer of electric energy can operate his items of electrical equipment as and when he wishes. The wiring extends from the consumer's terminals, where it is connected to the electricity supply mains, to the various outlet points such as ceiling roses and wall sockets. The term repair of electronics (opravy elektroniky )wiring is often used to distinguish the wiring serving the fixed outlet points from flexible wiring such as that attached to appliances, familiarly known as leads.

Wiring comprises cables together with associated apparatus for control and protection. Cables consist of conductors, insulation and sometimes mechanical protection. The purpose of a conductor is to carry the current, and it is therefore constructed of a material offering little resistance to the flow of electric current, such as copper or aluminum. The conductor is generally in the form of either a single wire or of a group of wires (known as strands) in contact with each other.

The function of insulation is to prevent the current from leaking away from the conductor at places where it is not required to flow. Thus, a material which offers an extremely high resistance to the flow of current is used for the electrical installations(elektro instalace), such as polyvinyl chloride (p.v.c.) or magnesia (mineral) service prague(servis praha).

Mechanical protection may take the form of an integral overall sheath of insulating material or metal, or the cable may be enclosed within a conduit, trunking or duct. Two or more insulated conductors included within a cable and provided with mechanical protection are each described as a core.

The form of protection used largely determines what is described as the system of wiring. Typical systems of wiring include p.v.c-insulated p.v.c.-sheathed cables, insulated cables within conduits (either metallic or nonmetallic), and mineral-insulated metal-sheathed cables.

Systems of wiring should not be confused with methods of wiring, such as the looping-in method employed when wiring is within conduits, and the joint box method applicable to sheathed wiring.
