With the ability to frame structures prevent the propagation of heat through them in a house in the cold and hot seasons remain comfortable thermal conditions. The ability of the enclosing structure to resist heat flow from inside out, is characterized by resistance to heat R0 R0 = 1 / v + Rk + 1 / n, where v – heat transfer coefficient inside surface of the fence (in most cases is assumed to be 8.7 W/m2 C) n – coefficient of heat the outer surface of fencing (in most cases is assumed to be 23 W/m2 C) Rk – thermal resistance construction, which depends on the material thickness () and its thermal conductivity (). This dependence is expressed by the relation: Rk = / m2 * C / W here is expressed in meters, and – a (W / m C) thermal conductivity is a characteristic of insulating material itself, while Rk characterizes insulating properties of the structure of certain thickness. Enclosing structures, usually composed of several materials of different thicknesses. In this case, the resulting thermal resistance is equal to the sum of thermal resistance of individual layers. The required thermal resistance R0 of enclosing parts determined by the conditions energy efficiency and in accordance with the requirements of snip ii *- 3-79 Building Heat Engineering" in the 1998 version for various regions of Russia, depending on their climatic conditions. For example, reduced resistance heat transfer of the exterior walls of the conditions of saving for Moscow and Moscow region is 3.2 m 2 * C / watt. .
Very rarely, modern manufacturers, supplying lumber, escorted their products technical description of its properties, the recommendations for use. After all, only to wholesalers or experts may be known by the quality of a timber. Many varieties have a high level of water resistance, so they are used for construction and finishing baths, attics, exterior walls, others are beautiful structure, in connection with what they recommended for indoor use. It must be taken into account, therefore, going shopping, take a master or go directly to the sales manager, he give all the necessary information to answer all your questions. Many modern industries, as well as the construction is inextricably linked with the use of materials made from wood. Delivery lumber today is carried out in very large quantities.
Their main customer is the furniture industry. Source: Tiffany & Co.. Although the products are partially replaced by a variety of boards and plywood, their relevance remains all the same high level. The smell of fresh wood can match virtually with nothing, he is unique. Softwood timber is a holder of a wonderful aroma, the creator of which is nature itself. However, it is widely use is associated not only with the fact that it fills the room fresh wood, resin which allocates pine, fir, spruce, cedar and larch to protect people from diseases. From this magnificent building houses and baths are used in shipbuilding and other industries.
Timber conifers are durable and high resistance against decay. Therefore, in a house built of these materials is always dry and comfortable. This is due to the fact that the tree structure provides a continuous exchange of indoor air, while its insulation properties in winter prevent leakage of heat, and provide coolness in summer. All this contributes to comfortable living. Beautiful texture, color and strength – these are the qualities that captivate the elite lumber. Oak is an aristocrat among other species of wood. Equal number of positive qualities with the Materials nobody can. It can be compared with iron and concrete, it is almost as durable as they are. Today it is used in large quantities for the production of furniture, doors, floorboards and other items. This wood has a very dense structure and therefore very heavy. In the old days it was widely used in shipbuilding. This is due to the fact that it is in the water, many times increases its strength characteristics. No matter how it was amazing, but true confirmed in practice as well as scientifically. Time – is the primary witness to the reliability of such timber. Oak can keep the original look of the centuries, thanks to the quality of our museums are now stored interior, made in the days of antiquity.
Plant Kamkabel certify their products to international quality standard iso 9001.Sistema quality of Kamkabel certified by the national Quality System Certification Institute of Certification (Moscow) for compliance with gost R iso 9001-96 (ISO 9001-94) 'Quality System. Model for quality assurance in design, development, production, installation and maintenance. " MoskabelZAO Plant Moskabel, successfully promoting their products and are constantly learning new kinds of production, is a subsidiary of Moskabelmet. On Currently a group of companies Moskabelmet – successfully developing industrial and commercial complex. Today, jsc Moskabel plant is the largest cable company in the central part of the Russian Federation and manufactures a wide range of power cables with impregnated paper insulated 10 kV, polymer-insulated (PVC, PE) voltage to 6 kV, including armored type and self-carrying insulated wires (SIP) voltage to 35 kV. Commercial production of a new generation of cable with insulation made of vulcanized polyethylene (IIc), fireproof cables, including low-gas-smoke release (with an index of "ng-LS, cable (with an index of "ng-HF and fire-resistant cables (with an index of "ng-FR.
Successful competition in the cable medium voltage to 10 kV can cjsc Zavod Moskabel for decades ensure that their products structure of rao ues, subway stations, facilities construction industry throughout Russia and cis countries. back almost six decades, and can rightly be proud of its history. All this time the plant has changed and is continuing to evolve to meet new market conditions, to be competitive. The main task of Rybinsk cable plant – to take strong position in the market, producing products that meet the highest standards of reliability and quality.
