WIRE ADJUSTING FOR WATER SUBMERSIBLE ELECTRIC MOTORS. Scope: The wire of the runway is intended for accession to electric networks on rated voltage to 660 V of the frequency of 50 Hz of water submersible electric motors, 106 Pas at ambient temperature are long the artesian wells working in water under the pressure up to 7,09 · From Design wire of the runway 6: 1-Conducting vein: copper, twisted. 2-Isolation: polyethylene. 3-Cover: light-resistant polyethylene. 4-Insulating and protective cover: light-resistant polyethylene. We make VPP2,5; 4, 6, 10, 16, 25, 35, H Description of a submersible wire: Wire with the copper twisted vein 2 classes of flexibility (in accordance with GOST 22483-77), with isolation from polyethylene, in a cover from light-resistant polyethylene (isp.1) or in a single-layer izolyatsionnozashchitny cover from light-resistant polyethylene (isp.2). |
Main technical characteristics: Rated voltage is 380 V, 660 Century. The test tension of alternating current of the frequency of 50 Hz within 5 min. (after endurance of a wire in water during 3 h): - 2000 V for a wire on rated voltage are 380 V; - 2500 V for a wire on rated voltage are 380 V; Ambient temperature at operation: - 40C to + 80C. Temperature at which installation of a wire - not lower minus 40C is made. Bend radius at installation - not less than 10 diameters of a wire. The provision of a cable of the runway during the long operation of water submersible electric motors in water of artesian wells under pressure to 7,09 · 106 Pas - fixed. Construction length of a submersible cable is specified in the table. Maximum deviation of construction length of a wire + 1%. No more than 5% of pieces of a wire not less than 7 m long are allowed in party. In coordination with the consumer delivery of wires is allowed by any lengths. Packing: bays in a film, bays in a film coordinated on the pallet, drums. Warranty period: 2,5 years from the date of commissioning. Average service life - 6 years from the moment of production of a wire. Average resource of a wire: - 32000 h at a temperature of 50C; - 20000 h at a temperature of 65C; - 16000 h at a temperature of 80C. Average shelf life - 5 years. |
