Power cable AVVGz – similar AVVG, but it applies to electrical installations that require sealing cables entering. AVVGz cable is a transmitter and power – electrical power cable received and subsequently distributed in fixed installations for rated voltage of 0.66, 1 and 6 kV, 50 Hz. AVVGz laid in dry and wet production areas. ource. Also, cable AVVGz You can lay in the open air, on cable racks or special in blokah.Konstruktsiya AVVGz AVVGz consists of conductor, and twisted shell of PVC (polyvinyl chloride plastic). Conductor AVVGz Aluminum, solid or stranded, the first or second class according to GOST 22483. The shape of veins are circular and sector formy.Izolyatsiya cable is made of PVC. Stranded cables are distinguished by Insulation color: Zero veins blue protective conductor two-color – green and yellow.

Stranding is a twist on cores of two-, three-and four-core cables. In the same vein bipolar cable section, and in three-and four-core cables, all conductors with same cross section or have lived a smaller cross-section (core grounding or zero-lived.) Cable brand AVVGz filled unvulcanized rubber and smesyu.Tehnicheskie performance cable AVVGz has the following specifications: Conductor – aluminum wire, insulation – PVC Plastic – PVC Filler – uncured rubber compound, Working temperature – from -50 to +50 C temperature of heating wires in emergency mode – max 80 C (under conditions of no more than 8 hours) Minimum bend radius: a single cable – 10 diameter stranded cable – 7.5 diameters; Cables do not spread burning; Resistance to bending assembly, cables have a high resistance to humidity of 98% at 35 C, as well as to the effects of mold, solar radiation and salt fog, life – 30 years Scope The scope of the power cable AVVGz covers several sectors of the economy, such as electronics, instrumentation, aircraft, telecommunications and electrical engineering, construction, relationship. Cables can be laid in areas with a temperate, cold and tropical climates. They operate both on land and in water bodies – lakes and rivers, and at an altitude of 4300 m above sea level.

One of the most popular types of lifting equipment are the usual lines of different species and different capacities. To date, production lines must be carried out in strict accordance with GOST, all products must be properly certified – because of so many seemingly insignificant details, and dependent quality of the hoisting works, and safe operation of the complex equipment. Slings are satisfied their steel and textile ropes. Textiles are used where special importance is the ease and flexibility of the product, they provide full safety of all the treasure to move is used. These products are unaffected by deformation, unlike steel, which shall be cleaned in areas of frequent bends.

Textile is much more resistant to aggressive media, textile slings themselves absolutely safe for humans, they do not drown, if you drop them in water and can always be at hand thanks to its compactness. However, there are situations where preferred products made from steel wire rope, slings must therefore choose only depending on the specific jobs and the environment in which they are used. Slings mats come in two forms: kruglopryadnye and tape. Belt slings made from the tape in two or crosslinking a single layer. The latter depends on the severity designed to lift cargo.

Kruglopryadnye lines represent a ring containing a core and a protective sleeve. Core consists of a polymeric material. The sleeve also eliminates the occurrence of the effect created when the friction of the core fibers during high-gravity lift luggage – it is a relatively new type of lifting devices, used in the rigging.

Creation of technological processes of plastic materials from synthetic polymers represents one of the greatest achievements of modern industry. Films have a significant place in the overall balance production of polymeric materials and their production is growing every year, surpassing the rate of development of other products. Most species are large-films based on polyolefins (2 / s total production), primarily polyethylene, and PVC and its derivatives, polyethylene, cellophane and cellulose acetate. Getting the film coatings is a key element in the process of creating various types of artificial leather. Therefore, the total consideration of specific processes in the industry of artificial leather is advisable to start with an analysis of technological schemes for forming polymeric film materials. Light industry produces multiple film materials, mainly based on two polymers – PHH and PE using to modify the properties of the films of compositions based on these polymers and thermoplastic elastomers, acrylonitrile rubbers, polyisobutylene, etc. In small quantities, also produces films based on mixed polyamides and polyethylene terephthalate. The largest share of the light industry account for elastic and rigid PVC film, the materials that get into a monolithic, porous, porous monolithic and perforated design. In some cases, in addition to conventional high-strength film received, which reinforced polymer nets made of synthetic fibers. The polymer film materials are intended primarily for the manufacture of consumer goods, social amenities, etc., including leather goods-GOVERNMENTAL products (bags, suitcases of rigid film, etc.), raincoats, for decoration and making the inside of the shoe manufacturing curtain and lace products, lighting materials (lamp shades, lampshades, lamps, etc.) to create bookbinding and other materials for the printing industry for the manufacture of baby carriages, toys, interior trim for cars, airplanes, furniture, etc.
