Abstract: A remote control cable has a central core formed from two conducting wires separated over their entire length by a textile element with which the wires are in intimate contact, preferably slightly embedded therein, the whole being covered by a coating of a thermofusible material. The central core is strengthened by filamentary reinforcing elements arranged in parallel to the conducting wires and by at least one, preferably two, layers of braiding over the reinforcing elements. The central textile element maintains the conducting wires separated and parallel to each other during manufacture and under conditions of use. The cables may be used for transmitting signals, e.g. electrical pulses, to remote objects, for example, to transmit directions for controlling objects moving at high speeds, e.g. up to 300 m/second or higher and over distances up to 4000 meters or more.
