For household electrical wiring, in most cases the following cables are us:
VVG is the most common wire, manufactur by a large number of manufacturers. For apartment electrical communications, it is the qatar email list 476676 contact leads best choice, while being distinguish by maximum diversity. Among its advantages are simple and less demanding installation, increas “survivability” of wiring and resistance of networks to various negative impacts.
VVG modifications Popular types of
The leading modification is the one with the abbreviation VVG, which denotes the standard model of the product. Also, changes and additions want to increase conversions? see how to create your landing page can be made to the initial version,
which is display as follows:
VVGng is a power connection cable that uses non-flammable internal insulation and external sheath. Such electrical installation products are us in most cases for the electrification of utility and technical premises.
VVGng-LS is a fire-safe cable
The protective layer of which does not ignite under the influence of open fire (self-extinguishing), but only melts with minimal smoke emission due to the absence of halogens in the composition. It is consider a household cable, us in the electrification of apartments and houses.
VVGng-FR-LS is a fire-resistant model of trust review electrical communications,
which is capable of withstanding open fire for a certain period of time. The cable design includes an additional fire-resistant mica tape. This modification is subject to the requirements for mandatory installation in fire extinguishing systems in institutions with a large number of people.
NYM is a German telecommunications standard whose name is the marking:
N – mark of conformity with the West German standard Normenleitung
Y – denotes the material of the insulating shells, which is polyvinyl chloride.
M – indicates that the wire has an outer sheath,
which is made according to the German standard – Mantelleitung.

J – equipping the cable with a protective earthing core; such cable must be paint with a yellow-green stripe.
O – there is a neutral conductor, which, according to the German standard, is paint blue.
Example of marking: NYM-J-3×2.5 – a model of cable products with PVC insulation and a grounding loop wire. Increas non-flammability of the wiring is ensur by additional rubber filling of the interconductor gaps.
