Abstract
A marine communication power cable relates to the field of power cable manufacturing. The cable comprises three strands of large-section insulated conductors and three strands of small-section insulated conductors, which are mutually twisted, and each strand of conductor comprises a tinned copper conductive core, wherein a belting layer, a polyolefine inner sleeve layer, a tin plated copper weaving armor layer and a polyolefine outer sleeve layer are sequentially arranged outside the twisted insulated conductors; a filling material is arranged between the twisted insulated conductors and the belting layer; and a crosslinked polyethylene insulating layer is coated outside each strand of tinned copper conductive core. The marine communication power cable has the advantages of good anti-jamming performance, high-temperature resistant performance, oil-resistant performance, transmission performance, and the like, and is suitable for telecommunication equipment in ships and water floating buildings, and a signal transmission and control system for electric instruments and various information processing devices.
