Abstract
The invention relates to the field of telecommunications, specifically to an optical and electric composite cable and a production method thereof. The optical and electric composite cable comprises an electricity transmission line, a signal transmission line and an aramid yarn core, wherein the outer parts of the electricity transmission line and the signal transmission line are both coated with insulating layers; the electricity transmission line and the signal transmission line are stranded together by taking the aramid yarn core as a center to form a cable core; and the periphery of the cable core is covered with an aramid yarn braid layer. According to the electric composite cable and a production method thereof, the electricity transmission line and the signal transmission line are stranded together by taking the aramid yarn core as the center to form the cable core, so that the force acting on the electricity transmission line and the signal transmission line can be transferred to the aramid yarn core and be absorbed, and the electricity transmission line and the signal transmission line can be prevented from being damaged. Because the aramid yarn layer made by braiding aramid yarn silk and the cable core are combined, the requirement of resistance to strong pressure can be met. Besides, the combination can provide good bending performance, and therefore the cable can be used in a narrow environment requiring the cable to be bent repeatedly.
Description
Technical field
