Problems solved by technology

The connecting ribs of the cable and the optical cable are rigidly connected. Due to reasons such as sag and phoenix dance, the force will be uneven, resulting in excessive deformation of the connecting ribs and tearing, and the cracks will extend to the insulating layer, which will easily cause the conductor to leak out.

Abstract

The invention belongs to an overhead insulated cable of fusing an overhead insulated cable for electric power transmission with an optical cable, a radio-frequency cable and a communication telephone cable, and particularly relates to a soft and elastic compound type overhead insulated cable. The cable and optical cable splicing bars of an overhead compound cable applied at present are in rigid connection, and uneven stress is caused by the reasons of sag, phoenix dance and the like to cause the splicing bars to be torn and extend to an insulated layer, thus, a conductor is easy to leak. Moreover, the splicing bars are excessively thick and solid, thus, the optical cable and the cable are not easy to separate. The invention aims to provide the soft and elastic compound type overhead insulated cable, which is characterized in that one or several of the optical cable, the radio-frequency cable and the communication telephone cable which are used as the additional cables of the overhead insulated cable, is/are spliced and merged with the overhead insulated cable for the electric power transmission by using soft and elastic splicing bars with spacing holes for application so as to solve the problems at present. The soft and elastic compound type overhead insulated cable is convenient in construction, does not need particular maintenance and is suitable for a novel multi-one network electric power transmission mode.

Description

technical field [0001] The invention belongs to an overhead insulated cable integrated with an overhead insulated cable for power transmission, an optical cable, a radio frequency cable, and a communication telephone cable, and is precisely a soft elastic composite overhead insulated cable. Background technique [0002] Today's optical fiber composite overhead insulated cables, such as Chinese patent 200920231879.5 optical fiber composite overhead insulated cable, 201020512395.0 parallel bundled optical fiber composite low-voltage overhead insulated cable, only use optical fibers or optical cables with power cables, and do not fully meet the needs of power transmission cables, optical cables, The effect of simultaneous application of radio frequency cables and communication telephone cables. The connecting ribs of the cable and the optical cable are rigidly connected. Due to reasons such as sag and phoenix dance, the force will be uneven, resulting in excessive deformation o...
