Beschreibung
Zusammenfassung:	FIELD: geophysical cables for studying vertical boreholes and for lifting and lowering instrumentation equipment. SUBSTANCE: flexible cable of enhanced load-carrying capacity designed for investigating very deep boreholes has central core made in the form of single insulated current-conductor formed by stranding steel and copper wires and covered with insulating sheathing, then braiding of type SVM threads complying with State Standard GOST 28007-88, NPP Germoteks , and low-pressure polyethylene or polyurethane jacket overall. EFFECT: facilitated manufacture, reduced sectional area and specific weight, enhanced resistance to multiple rewinding. 1 cl, 1 dwg
