Abstract. Due to the high engineering current density, flexibility and mechanical stability, Rutherford-type superconducting cables are widely used in the magnets of modern particle accelerators to create high magnetic fields. One of the main problems in the manufacture of Rutherford -type cables is the degradation of the current-carrying capacity and the decrease in the stability of the superconducting wires. This is largely caused by the increased deformation at the cable edges. Therefore, in the development and manufacture of such cables, certain measures should be taken to reduce the deformation of the wires at the cable edges. On the other hand, to provide the required mechanical properties, the cables must be compacted. The optimization of a balance between limiting wire deformation and the desired compaction of the cable can be achieved empirically by manufacturing and testing prototypes of the cable under development.
The paper presents a brief overview of the methods used in the development of Rutherford-type cables based on NbTi and Nb3Sn superconductors, and also summarizes the experience of their manufacture.

Abstract. Different trends are described for modernization of high voltage cable network equipped with high pressure pipe-type oil filled cables. Shortages and advantages of transition joints, used abroad for coupling oil-filled and XLPE-insulated cables are considered. The well-founded technical solution is selected for jointing high pressure pipe-type oil-filled cable XLPE-insulated cable with rated voltage of 110 and 220 kV, based on two transformer or GIS terminations installed in one housing.

Abstract. The article presents the results of investigation of the parameters of mutual influences at the far end of multi-pair LAN cables. The obtained data on the predominant components of mutual influence allow taking measures aimed at the reduction of mutual interference between the cable circuits at the stage of cable designing and manufacture. Based on the conducted investigations, a set of measures related to the multi-pair LAN cable manufacturing technology was developed which ensured the compliance with the requirements for category 5e cables.
Key words: multi-pair LAN cables, parameters of mutual influences, mutual interference at the far end
