Abstract: The cable rod is established in the place of the maximum rates of set of curva-ture for elimination of abrasion of a column of NKP and bars, for reduction of friction forces in couple of „bar pipe”. The article questions of a possibility of use of ropes of a different design as a rope bar are taken up. Results of researches of strength properties of plastically pressed out ropes of the Beloretsk plant the conditional module of elasticity of these ropes is defined and justifies the scope of such ropes as the sucker- robs. The design of the pump developed by authors with the vacuum chamber provi-ding the movement of rope bars at the course down is shown. Results of calculations of reliability (average operating time and probability of no-failure) of borehole pumping installations a cable rod (BPI with СR), are presen-ted on wells of LLC LUKOIL-PERM. Impact assessment of such factors as adjournment of ASPO, a deviation angle from a vertical and length of a rope bar on an average operating time is given.
