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. .
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.
