A single-core copper power cable is an electrical cable with a round cross-section, consisting of single-wire or multi-wire copper conductors, with plastic or paper insulation, impregnated with a viscous or non-draining composition, in a plastic, lead or aluminum sheath, with or without protective covers. Three-, four- and five-core cables must have all conductors of the same cross-section or one conductor of a smaller cross-section (grounding or neutral conductor). Six-core cables must have four cores of equal cross-section and two wires of smaller cross-section. Cables vary depending on the number of conductor cores: 2, 3, 4, 5, 6. The nominal cross-section of the conductor core is 1-240mm2. Current-carrying conductors are made of copper wire, tinned with tin or coated with tin-lead solder with a tin content of at least 40%. Insulated cable cores are twisted either with or without filling the spaces between the cores. A separating layer of synthetic film can be applied over the twisted cores. Manufacturing without a separating layer is allowed provided that the cores are freely separated from each other and from the shell without damaging the insulation and screens. The grounding conductor is made without insulation or with insulation made of electrically conductive rubber. Cables vary depending on the type of insulation material of the current-carrying conductors: insulation made of polyvinyl chloride plastic, including reduced fire hazard; vulcanized polyethylene insulation; paper insulation impregnated with a viscous or non-drip compound. Cables differ in design in terms of fire hazard indicators: flame retardant when laid alone (without designation); flame retardant when laid in groups (ng); flame retardant when installed in groups, with reduced smoke and gas emissions (ng-LS); do not propagate combustion during group installation and do not emit corrosive gaseous products during combustion and smoldering (ng-HF); fire-resistant, flame retardant when laid in groups, with reduced smoke and gas emissions (ng-FRLS); fire-resistant, non-flammable when laid in groups and not emitting corrosive gaseous products during combustion and smoldering (ng-FRHF); flame retardant when laid in groups, with reduced smoke and gas emissions and low toxicity of combustion products (ng-LSLTx); fire-resistant, flame retardant when laid in groups, with reduced smoke and gas emissions and low toxicity of combustion products (ng-FRLSLTx). A thermal barrier made of mica-containing tapes must be placed over the conductors of fire-resistant cables. Stranded round conductors with a nominal cross-section of 50 mm2 or more, as well as sector and segment conductors must be compacted. In impregnated paper insulation, the tapes must not have folds or breaks. The insulating impregnating non-drip composition should not leak out at the long-term permissible heating temperature of the cable cores. Cables are supplied on drums or coils with dense, uniform winding. Sheathing of drums with mats or partial sheathing is allowed to protect the cable from direct sunlight. We guarantee that the compositions of alloys of conductive cores and manufacturing technologies comply with the required standards and the high quality of the products presented in our catalog. The GOST 16442-80 cable has the following characteristic features: a wide range of operating temperatures from +50 °C to -60 °C; climatic version: UHL, T; stable operation in particularly difficult conditions at relative humidity up to 98% (at a temperature of 35 ° C); rated alternating voltage 0.66; 1, 3 and 6 kV with a frequency of 50 Hz or constant voltage up to 1 kV; Tropical cables (T) are resistant to mold; resistance to winding. The VVGng-0.66 cable is used for the transmission and distribution of electrical energy in stationary installations at a rated alternating voltage of up to 35 kV with a nominal frequency of 50 Hz. The cables can be used in DC electrical networks. Main characteristics.
