The invention relates to flexible geophysical cables for transmission and reception of high frequency electrical signals during seismic operations in field conditions at an ambient temperature of minus 60 ° to plus 55 ° C with an acceptable heating them in the summer to plus 70 ° C. Cable according to embodiments both comprising polypropylene or polyethylene insulated power two conductive strands twisted into pairs and conductive wires for transmitting electrical signals of frequency up to 12 MHz, characterized by a pair of color. In the second embodiment the cable comprises a twisted pair as polyethylene or polypropylene insulated conductive wires for receiving electrical signals of frequency up to 1 kHz. In the center of the cable is a reinforcing core sheathed in polyethylene or polypropylene, twisted from high technical yarns (the first embodiment) or the reinforcing element formed by a conductor pair conductors, twisted with two reinforcing bundles also from high technical filaments (the second embodiment) . All pairs and power conductors are twisted around a cable core or reinforcement of the reinforcing member. Above the common stranding superimposed winding of a polyethylene terephthalate film, and then the shell of a thermoplastic elastomer or thermoplastic polyurethane, or PVC. Steps stranding of pairs of mutually agreed upon. All current-carrying conductors are made of copper or tinned copper wire with tin. Consistency steps twist pairs, and also manufacturing of conductors of copper wires having a low resistance, allow to exclude the influence of high-frequency electrical signals to each other to provide a small power loss and low attenuation signal, thereby to increase noise immunity. Through the application of ultra-high technical filaments having high tensile strength cable has a small linear elongation under mechanical load. These filaments, soft, light and copper plastic cable provide flexibility, small size and weight.
