Smart energy high-tension-resistance cable and production technology therefor

Abstract

The invention discloses a smart energy high-tension-resistance cable and a production technology therefor. The cable sequentially comprises a reinforcing core, a cable core, a first polyester belt, a rubber spacer layer, a composite aluminum-plastics tape, a copper wire shielding layer, a second polyester belt, an internal sheath, a first braided layer, an external sheath and a second braided layer from the inside to the outside. The cable core comprises 36 wire cores. Each wire core sequentially comprises a conductor and a fluoroplastic insulation layer from the inside to the outside. The reinforcing core (1) is formed by the braiding of kevlar, and the external diameter of the reinforcing core (1) is determined through a formula: D=(4.15+k)*d, wherein k is a compression coefficient. When d is from 1.0 mm to 2.0mm, k is equal to 0.05; when d is from 2.0 mm to 4.0 mm, k is equal to 0.07, wherein d is the diameter of an insulating cable core. The weight (kg) that the reinforcing core (1) can bear is determined according to the formula: M=37.7*D2, wherein D is the external diameter of the reinforcing core (1), and the unit is mm. The cable is compact and stable in structure, is high in tensile strength, is high in softness, is small in collision sound of water and the cable, and is excellent in performance.

Description

technical field [0001] The invention relates to a smart energy low-noise high-strength cable for signal transmission connecting ground acoustic equipment and underwater equipment and a production process thereof. Background technique [0002] This product is used for signal transmission between hydrophones and underwater equipment. As the cables move with the hydrophone in the water, problems such as swinging, noise and sealing are prone to occur, so the requirements for cables are very high. The cable mainly has four key points: 1. Reduce the swing with the water flow or waves; 2. Reduce the noise caused by waves hitting the cable; 3. The end of the cable is waterproof; 4. Water pressure can easily cause the shield to scratch the insulation and cause damage. invalidated. [0003] In order to reduce the swing of the cable with the current or waves, heavy objects should be suspended under the cable, so the cable is required to have a high tensile strength. The center of the...
