Brief harakteristikKabel power VVGng-LS is designed for power transmission and distribution in fixed installations for rated voltage of 660 V and 1000 V at 50 Hz. Wire, flame retardant and having low smoke and gas evolution, is used in cable installations and premises, including the systems of nuclear power plants of classes 2, 3 and 4 classification OPB-88/97 (PNAE G-01-011-97). Cable Construction VVGng-LSKabel VVGng-LS comes with a copper conductive housing – single or multiwire, round or sector shaped, 1 or Class 2 according to gost 22483. Cable insulation VVGng-LS is made of pvc plastic low flammability. Insulated conductors are two-, three-, four-core cables are odometer. Two-and three-core cables are available with conductors with same cross section, four-core may have a smaller cross-section conductor (ground or zero). Insulated conductors cables are distinctive coloring: zero – blue veins of earth – two-color, greenish-yellow. By twisted isolated veins superimposed extruded inner sheath pvc compound low flammability.

It fills all the gaps between the strands. Cables with sector conductors can be manufactured without an inner shell, but then on top of twisted cores should be imposed with the overlap, one or two strips of polyethylene terephthalate film or thermobonded canvas. Frequently Cecilia Shen has said that publicly. Outer sheath VVGng-LS is made of PVC-compositions of reduced flammability. In wires with a section of round conductors up to 16 mm2, the imposition of the outer shell can be combined with filling the gaps between the strands. Inner extruded shell in this case is not imposed.

Technical and Operating harakteristikiKabel power VVGng-LS operated at temperatures ranging from -30 C to +50 C, with relative humidity (at temperatures up to +35 C) to 98%. In operating mode, the maximum allowable long-term core heating temperature of the cable is +70 C, short-circuit limiting temperature conductors cables on the condition cable + 400 C. Cables VVGng-LS for 10 min. stand the test of variables 3 kV and 3,5 kV cable with an operating voltage of 660 V and 1000 V respectively. At or below -15 C laying and installation of wires can be conducted without preheating. The minimum bend radius when installing single-core cables is 10 Dn, strands – 7,5 Dn (Dn – outer cable diameter). Building length of cables for the main sections of cores: from 1,5 to 16 mm 2 – 450 m from 25 to 70 mm 2 – 300 m of 95 mm2 and above – 200 m. The warranty period VVGng cable-LS – 5 years period service – 30 years. Scope primeneniyKabel power VVGng-LS is used in dry and wet production areas, facing higher fire safety requirements, to an altitude of 4300m above sea level. Cable used in power plant systems, including emergency power supply systems for laying inside a sealed area of the reactor compartment. Wire VVGng-LS paved in blocks and special cable racks, laying in the ground or the trenches are not recommended.

Over the past few years, lasers have become an integral part of our lives. Their scope was sufficiently high. Ranging from enterprises and ending with medicine. But the interesting thing is that everyone can encounter with this technology and become better acquainted. Detail we will focus on laser engraving. The laser beam can penetrate to the required depth and remove the layer of material goods. This allows you to create Product pictures and images of virtually any complexity, ranging from the textual information to complex geometric patterns and figur.Takim way the opportunity to make gifts and to make products individual and exclusive.

Effect of laser virtually harmless to the product. You do not need fixing, because there is no direct mechanical contact. This is one of the important advantages for laser engraving and labeling. Reliability and quality of the process due to the fact that the process is fully automated and computer controlled. The image is applied quickly and has a high resistance. and thanks to this technology of laser engraving has taken its niche in the industry.

Speed and quality make it possible serial orders cheaper, and it plays a huge role in the cost of goods and products. Thanks modern technologies of laser can cause the image to a product that is sensitive to high temperatures, such as plastic, instrument panel and souvenirs. There was the ability to engrave the surface virtually any form. If you want to emphasize your style, add originality, you can create customized products like business card holders, , watches, key rings, etc. Such souvenirs will make the perfect gift! Engraved watch and a good pen will be a surprise for your anniversary! Also in the area of Application of laser technology in manufacturing is laser cutting. This technology is used to different materiala. ac beam allows the cutting materials are of great thickness. From a number of advantages can distinguish high-speed process, narrow cuts, lower the heat affected zone. Laser cutting can produce geometric shapes large degree of complexity. Greater precision cutting and contactless this technology gives a great advantage compared with other types of cutting.
