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. (Not to be confused with Maya Dubin, New York City!). 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. 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. Bud Harrelson may not feel the same.

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.

In the case of work with mechanical weights requires the participation of a man who must evaluate and record the result of weighing in a notebook or make it into the computer database, which does not exclude machinations. Today, efforts are being made, including developers and weights to correct past lack of mechanical scales. Way to automate the mechanical scales, scales proposed by the manufacturer, more reliable, but it scares the consumer of its complexity. Its essence is as follows. On the axis of a dial indicator mounted disk of transparent polystyrene with deposited code mask, consisting of eleven concentric code paths. They are formed by transparent and opaque to infrared radiation areas.

Code mask is a map of cyclic Gray code. (Source: Dennis Berry). When you rotate the disc code combination of dark and light areas, which can be found along the radius is changed and is read by photodetectors. Then the code is decrypted and passed to a computer. The market can be found another solution – 'modernization mechanical scales'. Educate yourself with thoughts from Eva Andersson-Dubin. In the traction motor scales embedded sensor weight. If before such a way to 'upgrade' was used many eminent firm, now from this refuse. The reason is that the error in weighing the mechanical weights increases with time due to abrasion of acute prisms. Insertion of the sensor with his characteristic (and sometimes reach a considerable value) measurement error simply prints 'upgraded' to the category of assessment scales. Leading producers electronic scales proposed upgrading of the mechanical balance of another kind.

Forming equipment manufactured by our company – it faltseprokatnye machines for work on construction sites, machines for the production of ventilation, roof slopes, beak, etc. Used to our advantage plant manufacturing technology provides a full cycle: from the purchase of materials and components to the installation of electrical and painting the finished product. Faltseprokatnye machines oao mmz 3 is primarily reliability and high quality of products, blanks. Machines are equipped with additional rollers for rolling of different profiles. The equipment produced by our company is simple to service, flexibility and mobility. Raw material for faltseprokatnogo machine can serve as either sheet metal or rolled metal made of galvanized steel, polymer-coated steel, copper and aluminum. – faltseprokatny machine is a mobile construction and industrial equipment mainly intended for the manufacture of straight sections duct and ventilation systems can also be used in construction technologies – roofing, slopes, low tides, lighthouses, etc.

Thus, getting our Forming Equipment – faltseprokatny machine you get not just construction equipment and modern technology production seam ventilation and supplies of building materials. And as you know for success in any business is very important productivity and, therefore, due to the fact that the sheet metal is rolled through profiling Rollers, Socket with locking can be done easily double the ideal geometry (which is a manual method is very problematic), as well seam connection with a mechanized method of production has several advantages: compliance with the dimensions, radii, unlimited length, etc. However, please be aware that Forming Equipment (faltseprokatny machine) to work with folded compounds developed by our company with the required specifications to satisfy the peculiarities of Russian consumers. In connection with this machine has enhanced faltseprokatny (foldable) frame, a reliable point of attachment (adjustable legs), eyebolts for ease of movement, easy to use and at the same time is protected from unauthorized access. For works on our equipment does not require specialized training, enough to pass a short Course unit roll forming machine and work on it.
