What is different from the wire cable

Often, and wire and cable, we refer to one and the same conductor and believe that these terms are identical. But in fact it is not, this can be seen just by looking at price tags in stores. The cable wire is always more expensive. So let's see what the cable, and that such wire.

Unlike cable wires

Quite general description of what is a cable or wire can be found in textbooks, manuals, specifications or guests. A clear description of the division and the cable on the wire can be found only in the specification, it is stated that there will be a kind of product.

If we turn to electrical, then it is considered a wire conductor consisting of a monolithic core or multi-core and coated with a single layer of insulation, or even without it.

Cable also called aggregate insulated by conductors united into a common beam with another layer of insulating material for protection against the harmful effects of the environment.

Obtained: Wire - single conductor cable - with a double set of conductors and a layer of insulation.

So now we know what is called the cable, and that is called a wire. But these products can still be divided into several categories, depending on what they are made, and what do they have the characteristics of steel.

Wire is divided into the following categories:

1. Flexible (stranded) wire, e.g., MF-3 flex performance wire, copper.

2. Hard (monolithic conductor), for example PV-1 wire copper wire one species.

Called flexible conductor made from a plurality of individual conductive wires, these or woven in one piece. Such a conductor can withstand a large number of bends and actively used, e.g., to carry a plurality of power cords and appliances.

Hard conductor provides the least resistance during power transmission, and it is applied, e.g., for mounting fixed wiring, laying in the ground. It can also be formed as a single insulation, and in general without it.

Insulation and cable sheathing

In simple terms, the more insulation the better. At the same time, job security cable with a double isolation is 30 years, and single 15 years.

As it is necessary to pay attention to the material of the insulating layer thereof is formed:

If the cable is protected by PVC insulation, it can be laid in cable ducts or in the usual place.

Polyethylene insulation allows to lay cables in the soil as well as conventional open-pit.

If present in the abbreviation NG, it means a conductor made of non-combustible materials and is safe in case of emergency.

Designation E120, E60, E30 indicates that a conductor is capable without damage during the 120, 60 and 30 minutes respectively be exposed to open flame.

Now that you know how to distinguish between a wire from the cable, and get acquainted with some of the insulating material. Thanks for attention.
