Abstract

The invention discloses an instrument cable for a reinforcement shielding ship. The instrument cable comprises a plurality of insulation wire cores, insulation sheaths, a positioning shielding sleeve, diversion rings, a diversion core, a flame-retardant filling layer, an insulation inner sleeve, a shielding layer and an insulation outer sleeve, wherein the insulation sheaths sleeve the outer sides of the plurality of insulation wire cores, a plurality of positioning shielding rings are arranged on the positioning shielding sleeve, two insulation wire cores are arranged in each positioning shielding ring, the diversion rings are arranged in the positioning shielding rings, the diversion core is arranged at the central line of the positioning shielding sleeve, the diversion rings are connected with the diversion core, the flame-retardant filling layer is arranged on the outer side of the positioning shielding sleeve, the insulation inner sleeve is arranged on the outer side of the flame-retardant filling layer, the shielding layer is arranged on the outer side of the insulation inner sleeve, and the insulation outer sleeve is arranged on the outer side of the shielding layer. The instrument cable can have the advantages of high shielding, interference resistance, reasonable structure, low production cost and simple process on the premise of ensuring electrical performance.

Description

technical field [0001] The invention relates to the technical field of cable manufacturing, in particular to the technical field of reinforced shielding instrument cables for ships. Background technique [0002] The wire and cable industry is the second largest industry in China after the automobile industry, and the product variety satisfaction rate and domestic market share both exceed 90%. Worldwide, China's wire and cable output has surpassed that of the United States, becoming the world's largest producer of wire and cable. With the rapid development of China's wire and cable industry, the number of new enterprises has been increasing, and the overall technical level of the industry has been greatly improved. With the trend of shipbuilding enterprises to increase the payload of ships, the current double-sheathed marine instrument cables and braided armored marine cables without inner sleeves are increasingly unable to meet the development needs. Double-sheath marine i...
