Options laying and wiring methods
In the new construction or renovation work during the selection option and wiring installation method is an important element in the preparation for the production of electrical work. In particular, in the residential method of laying electric wires can affect the appearance of the premises and applied design solutions. On the production selection of options is based on the mission, temperature and other parameters of technical facilities, which may have high humidity , fire or explosion hazard environment , active in chemical terms . Thus, a method of laying electric wiring and related to environmental conditions , and specifications of building object. Be that as it may, without the hidden and open wiring , and electricians performing the routing and maintenance, the world would be much less light . In the construction industry for electrical wiring refers to a set of cables, mounts , cables and supporting details.
Distinguish between several types of wiring : hidden , outside, open , and outside, in turn, can be either hidden or open. When choosing between these options is necessarily considered , in what environment ( indoors ), they will be used : normal , wet, dry , hot, wet, dusty , with fire or explosion or chemically active environments.
The design of lighting networks , as well as the method of installation is also determined by the degree of flammability of building materials , which will be mounted on the wire. In addition, for the reliable operation of electrical wiring is very important section and the brand of electric cable networks laid in buildings.
One of the most common types of installation of lighting networks is an open standard wiring , which can be laid on supports, ceilings , wall area , and other parts of the design of buildings . And laying a harness made in several ways: in metal or plastic pipes , the area of walls and building structures on the ceilings on the ropes , strings, rolls , in boxes and on special trays.
String wiring commonly used for equipment distribution , transmission lines in the power networks , and light from the outside and the inside of the premises. Cables in the electrical wiring of string hung on a steel string , attachable close to the projections of various building elements.
Wiring with safety cables in area of walls, ceilings , on special tapes and bands . For attaching to the walls and the ceiling are used brackets mounted on the wall plugs and screws, and for connections – junction boxes .
Electrical wiring in polypropylene and polyethylene pipes can be installed and hidden, and openly , including special channels of various construction elements, building floors . Non-metallic pipes are used if the maximum temperature does not exceed 60 degrees Celsius , so they are not usually used in hot shops , which usually are laid steel tubes.
Electrical wiring in ducts and trays used when a large number of cables flows are difficult to mount other methods , it is necessary to lay on the tracks one . The advantages of this method of laying electric wires is the fact that he is without any labor costs allows you to change the circuit pass the cables , which is especially important in a regular change of equipment and technology.
Concealed wiring kind usually laid in foundations , ceilings etc. gasket typically may be in plastic or steel pipes and flexible hoses , conduits or cavities of different building elements and structures . The most time-consuming and costly , but different decorative options flush is its gasket is inside the partition wall and ceilings stipulated in the voids .
A simpler way is wiring on walls and ceilings in manufactured by perforating the grooves and grooves – Grooves . The cables in this case are skipped in a flexible PVC tube that protects the wires from damage during installation and operation.
Many pave the hidden wiring directly on the surface of ceilings and walls , fixing her nails and alabaster . During the finishing coat is covered with wire or line the walls of plaster. This option is also considered to be safe because of the high fire resistance material finishing , but inconvenient , if necessary, repair or removal of electrical wiring.
One of the common applications hidden wiring is to use it to power the ” home theater ” – complex from an electrical point of view of systems consisting of video and audio components connected to each other by different types of cables. When buying a home theater system to its new owner immediately raises the question of competent lay concealed wiring to power the audio and video voltage of 220 volts and speaker cables . This usually requires the use of integrated approach , taking into account the particular room layout and design of the room and the amount of the available funds .
To pave the hidden wiring under the theater , you need to proshtrobit section of the wall from the receiver to the speakers and conceal the wires in it , making special screw terminals for each of the columns. Common terminal screw type is typically located behind the receiver and the subwoofer will be enough wires from the receiver to the paved way to the exposed wiring .
The above methods and options for wiring networks give an idea of the variety of existing electrical wiring used to carry out skilled electrical work. Tellingly, each of the described methods of the electrical installation has its own scope and application in the context of the conditions of the external and internal environment of the premises used by modern building materials and technologies.
