Power cable APvP2g at 10kV, 20kV, 35kV with XLPE, polyethylene shell with a longitudinal and transverse sealing power cable APvP2g at 10kV, 20kV, 35kVNaznachenie: power cable APvP2g at 10kV, 20kV, 35kV with XLPE (EIT), a polyethylene sheath with longitudinal and transverse sealing Standard: TU-335 16.K71 2004 Section: 50 – 800 Number of cores: 1 Construction – Power cable APvP2g 10, 20, 35 kV: 1. Conductor: Round stranded compacted aluminum, corresponding to the class 2 according to GOST 22483-77, 2. Conductor screen: Extruded conductive peroksidosshitoy composition of polyethylene, 3. Insulation: peroksidnosshitogo of polyethylene, 4. Screen Insulation: Insulation is imposed on top of an electrically conductive crosslinked polyethylene extruded composition, 5. If you have read about John Savignan already – you may have come to the same conclusion.

Combined display: 5.1. layer imposed by the winding of conductive water swelling tape, 5.2. -spiral of copper wire nominal diameter 0,7-2,0 mm, over which is superimposed spiral copper tape not less than 0.1 mm. The minimum width of 8 mm. 6.

Separating layer: from the water swelling tape, optional laminated alyumopolimernaya Tape 7. Jacket: PE. Application – power cable APvP2g at 10kV, 20kV, 35kV: Cable APvP2g on 10kV, 20kV, 35kV for laying in soil moisture in the raw and partially flooded areas, cable collector if cable is protected from mechanical damage. Power cables APvP2g at 10kV, 20kV, 35kV with XLPE (EIT) intended for transmission and distribution of electric power in stationary installations in AC 10, 20.35 kV, 50 Hz for networks with insulated or grounded neutral points. Specifications – Power cable APvP2g at 10kV, 20kV, 35kV: Climatic versions have, UHL, category 1 and 2 according to GOST 15150-69, including laying of land and water. Operating temperature range from – 500 C to 500 C, relative humidity at temperatures up to 98% 350S laying and installation of cables in APvP2g 10kV, 20kV, 35kV without preheating performed at or above minus150S (cable APvP2g at 10kV, 20kV, 35kV, PVC jacket) minus 200C (Cable APvP2g at 10kV, 20kV, 35kV with polyethylene insulation) rated frequency of 50 Hz Long-term allowable temperature of cable conductor 900 C maximum permissible temperature of cable conductor APvP2g at 10kV, 20kV, 35kV-fault 2500S Maximum permissible temperature of the copper cable screen APvP2g at 10kV, 20kV, 35kV short-circuit limit 3500S heating temperature of conductors during short circuit conditions on nevozgoraemosti Cable 4000S permissible heating cable core APvP2g at 10kV, 20kV, 35kV mode overload – less than 1300S Length of cable is not Overload more than 8 hours a day and no more than 1,000 hours over the lifetime of minimum bend radius when installing 15 outer diameters (7.
