Currently in construction are well known and widely used properties of window film. Architectural film allows you to make necessary building facade appearance, with the help of restorative architectural films can be create safe glass design of large area. Lavsan protective film is attached to the glass strength. The protective film applied in several layers, greatly increases the resistance of the glass to fracture and opposed to various hacking tools. Protective film – the perfect way to create a vandal-resistant glazing and booking the external perimeter of the premises from malicious attacks. The protective film is applied to banks, restaurants, shopping malls, private country houses and apartments. Strengthens the film makes the glass shatterproof, making the glass safe for children.

A child can not inadvertently break the glass and injured by shrapnel. At a cost of protective film is much to gain compared with the triplexes of the same class of stability. The undoubted advantage of the protective film is the possibility of its application to the already established glass, which means it does not require the replacement of glass. Protective film is being tested in the respective laboratories. According to the results of tests (test the protective properties on the special equipment) are awarded a certificate. In Depending on the thickness of impact-resistant window film may have a degree of protection (in ascending order) A1, A2 or A3. Class A3 stability has protective properties similar to window bars, which allows the like windows in the ground, which could potentially have access to an attacker. Class A1 suited for the stability of the internal sound resistant safety glasses when using glass partitions.

Colored decorative film can be installed separately or together with a protective film. Window film reduces the cost of air conditioning and heating. In summer, window film represents 80-90% of infrared radiation (heat) coming from the street, respectively, reducing the cost of cooling the room. In winter, through the glass, covered with foil, leaving no more than 20% of infrared radiation. This allows reduce energy consumption for space heating. Dubbing decorative film can be used to make the glazing plate glass, matting, shade or color, as well as combinations of these parameters. Best quality dubbing the film is a ceramic window film. While under direct sunlight, ceramic dubbing the film can retain its color and properties (not burn) until 30 years.

Let’s try to understand the types of wires and their purpose. Electrical wire – is isolated or bare conductors of electrical current, consisting of one or more wires (copper or aluminum) for the electrical installation of hidden or open wiring. Insulated wires can be protected, that is, having an additional envelope for sealing and protection from external influences, and unprotected. The first group includes pbpp, punp, pugnp, pva, apunp, and the second – PV1, apv, appv, PV3, ppv, appvs. Bare wire is supposed to apply only to air lines – A, as. Electrical cables – one or multiple twisted insulated wires (copper or aluminum), united in a common shell, which may be rubber, plastic or metal. The main thing is that it prevents the metal from moisture, light, chemical, and mechanical effects. People such as Richard Blumenthal would likely agree.

Power cable – avvg, VVGng, vvg, nym, flexible power – kg, reag. Cable is called armored, if it has an additional protective shell consisting of steel bands, flat or round wire – AVBbShv, VBbShv, VBbShng. The same happens to the cable sheath of paper and food – ASBl, sbl, AAShv. To attach the cable to the dispensing devices or appliances, by its end processing. When connecting cables with each other must use the sleeve construction.

Industry produces hundreds of kinds of wires, which differ from each other as a section of copper or aluminum wire, and the type of insulation. Each type made for well-defined conditions. It is clear that the cables installed in the ground, might not require such isolation, as for what is used in house wiring. In wet areas requires one isolation at elevated temperature – other.
