FIELD: oil and gas industry. ^ SUBSTANCE: signal transmission pipe containing tubular body is equipped with communication element on its end or near it, elongated underlay and one or several connecting wires. Elongated underlay is fixed along inner wall of tubular body with tubular bushing extended inside the tubular body. Connecting wires are routed along underlay by locating them between inner wall of tubular body and section of underlay and connected to switching communication element to form the wire communication line. As per the other version of invention, signal transmission pipe is equipped with tubular body having one or several grooves at least in one of inner and outer walls. At that one or several connecting wires pass along one or several grooves. Connecting wires are fixed in grooves by being pulled through one or several additional pipes. At that, each additional pipe is fixed in one of the grooves and has the shape and orientation for passage between switching communication elements. ^ EFFECT: improving reliability and efficiency of signal transmission. ^ 19 cl, 27 dwg |
