In 1884, Thomas Edison's "power plant" (considered the inventor of the incandescent light bulb) began operating, providing electricity to five hundred homes in Manhattan, USA.
Two years earlier, Thomas Edison had patented one of the key items that enabled the connection of the power plant to consumers, it was an item
Which Thomas Edison called an “electric conductor,” this was the first electrical cable, a copper wire enclosed in a sheath.
Waterproof, made of electrically insulating material.
Today, there is a huge variety of electrical cables, Electrical conduits And additional accessories from which electrical infrastructures can be installed for homes, businesses and industrial electrical infrastructures.
In businesses specializing in electrical accessories, you can find cables of different thicknesses, containing a certain number of wires, and there are conduits of different thicknesses and made of different materials.
Designed for installation inside the wall as well as those designed for installation on the wall or ceiling. Here is a brief overview of the variety of cables and ducts
Currently used in the construction of electrical infrastructure.
Walls
Electricity flows from the electrical panel to consumers via cables. The cables must be laid out so that they are firmly anchored in place, no pressure is applied to them, and they are not exposed.
heat and preferably protected from sunlight and moisture (except for cables intended for this purpose). Electrical conduits are used to lead electrical cables to their destination. When it comes to a single cable
Or several strands threaded together from one point to another inside the wall, you can dispense with a duct and route the cable inside a suitable threaded pipe.
(Do not use a conduit intended for communication cables to route electrical cables).
In general, electrical conduits can be divided into two types, tin conduits and steel conduits. PVC . In both cases, this is a material that is not prone to fire,
Tin gutters are stronger but may develop rust over the years. You can find gutters PVC In a variety of sizes (the smallest are called “finger canals”),
Slotted tin ducts also come in several sizes. In general, the average width of slotted tin duct models is larger than the average width of ducts. PVC . 
Many types Cables
It is very important to choose a cable that is suitable for the electrical load we plan to transmit through it, for higher current you need larger diameter copper wires. One of the things
electricians are responsible for is choosing the thickness of the cable required. There are cables with three wires, blue, brown and yellow/green. There are also cables with five wires,
A three-phase cable, in which, in addition to the blue wire and the yellow/green ground wire, there are three brown wires (the three phases), usually one brown,
One brown with a black stripe and one brown with an orange stripe. There are also cables with four wires in them, brown, blue, yellow, green and purple, cables like that
Used for switching (e.g. separate control of two consumers installed side by side).
Safety above all else
It is very important to understand that accessories such as cables, tin ducts, ducts PVC , Threaded pipes , connectors, support arms, etc. are intended to play an important role but
Even before examining how well a particular model meets practical requirements, we must make sure that it can be used knowing that in terms of safety there is no
We put ourselves or others in danger.
Using electricity involves the risk of electric shock as well as fire (as a result of overheating due to overload or short circuit). All accessories used in the construction of electrical infrastructures
We are required to meet strict standards designed to ensure heat resistance, sufficient insulation, use of flame-retardant raw materials, and more.
Reputable businesses in the electrical accessories sector only sell items that carry an Israeli standard mark. Such a standard mark is enough to know that it is a cable,
A drain or other accessory of a high quality and safe type to use.
