The invention belongs to the technical field of cables and relates to a microchannel structure cable used for electric power or communication. The microchannel structure cable used for the electric power or communication comprises a skeleton body, multiple bone blades, multiple skeleton channels, a reinforcer, multiple cable cores, a protective layer and a sheath layer, wherein the skeleton body, the bone blades and the skeleton channels are formed an integrated manner, the bone blades are arranged at the edge of the skeleton body, the reinforcer is arranged at the center of the skeleton body, the skeleton channels are formed between adjacent bone blades, the cable cores are arranged in the skeleton channels, the protective layer coats the outside of the bone blades, and the sheath layer coats the outside of the protective layer in an extrusion moulding manner. The microchannel structure cable used for the electric power or communication is characterized in that the outer edges of the bone blades and the outer edges of the skeleton channels are arranged on the side of one cylinder, one opening is formed in each skeleton channel, the openings are towards the sheath layer, width of each skeleton channel at the opening is smallest, and width is gradually increased from the opening to a position near the bottom of the corresponding skeleton channel. The microchannel structure cable used for the electric power or communication has the main beneficial effects of easy production, relatively high passing rate of finished products, low production equipment investment, less resource consumption, higher product density and more stable product quality.
