10kv-35kv optical fiber composite overhead insulated cable with rated voltage

Abstract

The invention relates to a 10kv-35kv optical fiber composite overhead insulated cable with a rated voltage. The 10kv-35kv optical fiber composite overhead insulated cable comprises an internal reinforcing core, a conductive layer, a conductor shielding layer and a crosslinked polyethylene insulating layer, and the internal reinforcing core comprises an optical fiber unit and one or more aluminum-clad steel wire layers stranded with the optical fiber unit. The conductive layer is composed of one or more aluminum wire layers which are twisted around the periphery of the internal reinforcing core. The crosslinked polyethylene insulating layer and the insulating layer are coaxially arranged and sequentially sleeve the periphery of the conductive layer from inside to outside. According to the technical scheme, on one hand, the problem that a conventional power transmission cable and a conventional communication optical cable are erected separately is solved, and steel strand pulling, cablefitting installation and other work do not need to be conducted in the construction process; and on the other hand, through structural design optimization, the optical fiber composite overhead insulated cable has good consistency with the conventional overhead insulated cable in geometric dimension, mechanical property and electrical property.

AI Technical Summary

Problems solved by technology

However, existing communication optical cables usually do not have the ability to withstand large tension values. Therefore, in actual construction, it is necessary to pull steel strands in parallel and attach cable fittings (such as suspension clamps, tension clamps, and fastening fixtures, etc.) ) to achieve long-term reliable and stable operation of cable lines, which inevitably increases the complexity of construction and increases the cost of input and expenditure
