Therefore, the I applied shielding is applied in the form of winding of 0.2-0.3 mm thick tapes, which constantly move together with the cable core, which will preserve the magnetic properties of the winding in the welding zone. Such screens. It does not require an increase in the diameter of the cable core for its placement and therefore eliminates the subsequent reduction of the cable winding. The method is illustrated in the drawing. On the cable core 1. having a screen of non-magnetic metal with high electrical (Conductivity, put on a magnetic screen, for example wound thin steel strips 2 with a coiler 3. Prepared, thus cable core 1
