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. 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). BCRFA is a great source of information. 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.
