Specifications

Type of climatic modification UHL, placement categories 1 and 5 in accordance with GOST 15150.

Cables withstand crushing load: not less than 158 kN.
Insulated conductors are longitudinally sealed at a liquid pressure drop of 0.02 MPa per 1 m of length.
Electrical resistance of the insulation of the main conductors, recalculated for a length of 1 km and a temperature of 20 ° C: not less than 2500 megohms.
Cables withstand the test with a direct current voltage of 18 kV (nominal cable voltage 3.3 kV), 20 kV (nominal cable voltage 4.0 kV and 5.0 kV) for at least 5 minutes, with the insulation leakage current recalculated for a length of 1 km and a temperature of 20 ° C does not exceed 1x10 - 5 A.
Bending radius of cables: not less than 380 mm.
Descent - lifting and rewinding operations with the cable should be carried out at an air temperature: not lower than - 30 ° С.
Cable rewinding and hoisting and hoisting operations with it are allowed at an air temperature not lower than - 40 ° С in conditions of artificial heating of the cable, which ensures a temperature not lower than - 30 ° С.
The cables are resistant to temperature changes from - 60 ° C to the long - term permissible core heating temperature.
Descent of the cable into and out of the well should be carried out smoothly at a speed: no more than 0.25 m / s.
When passing sections of the well pipe string with a curvature of more than 1.5 ° by 10 m and the transition points of the string to a smaller pipe diameter, the speed of descent and ascent should not be more than 0.1 m / s.
When fastening the cable to the tubing and screwing pipes together, it is not allowed to twist the cable around the pipes, as well as twisting the flat cable about its own axis.
The supply of the cable is made with the construction lengths agreed with the Customer.
Warranty period for cables: 18 months from the date of commissioning, but not more than 24 months from the date of shipment to the Consumer.
