Embodiment Construction

[0025] see figure 1 , the structure of the heat-resistant instrument cable for ships in this embodiment is set as:

[0026] The cable conductor 1 is twisted by a plurality of tinned copper wires drawn by copper rods, annealed and tinned, and an insulating layer 2 is extruded on the conductor 1 to form an insulated core, and two insulated cores form a twisted unit 3. The cable core 4 is formed by twisting a plurality of pair-twisted units 3; and the outer surface of the cable core 4 is sequentially provided with a longitudinal drain wire 5, a tinned copper wire braided shielding layer 6 and an extruded sheath layer 7; the insulating layer 2 and the outer sheath layer 7 are made of fluororesin extruded material.

[0027] In specific implementation, the cross section of conductor 1 is 0.5 mm 2 , 0.75 mm 2 or 1.5mm 2 ;Conductor 1 is made of seven or nineteen tinned copper wires through regular twisting; insulating layer 2 and outer sheath layer 7 are made of meltable polytetra...

Abstract

The invention discloses a heat-resistant instrument cable for ships and a manufacturing process of the heat-resistant instrument cable, and is characterized in that a cable conductor is formed by twisting a plurality of tin-plated copper wires which are drawn by a copper rod and are treated by annealing and tin plating; the conductor is extruded with an insulating layer to form an insulating cable core; a twisted-pair unit is formed by two insulating cable cores; a cable core is formed by twisting a plurality of twisted-pair units; the outer surface of the cable core is provided with a longitudinally-added drainage wire, a shielding layer weaved by the tin-plated copper wires and an extrusion sheath layer in sequence; and the insulating layer and the outer sheath layer are respectively made of fluororesin extruding materials. The heat-resistant instrument cable is suitable to be used as an electric instrument connecting line under the severe high-temperature environments such as near diesel engines and in control chambers, and has the advantages of small structural size, high temperature resistance, water vapor resistance, flame retardance, acid-alkaline chemical agent resistance, fire resistance and excellent electric performance and mechanical performance.

Description

technical field [0001] The invention relates to a control cable for electrical equipment and a manufacturing process thereof, in particular to a heat-resistant instrument cable for ships and a manufacturing process thereof, belonging to the technical field of electric wires and cables. Background technique [0002] In recent years, in the design of marine engines, automation and high-tech are rapidly advancing, so the number of cables used tends to increase. At the same time, the hull is also required to be lightweight and compact. Therefore, in addition to meeting the electrical and mechanical performance requirements, the cables must also meet the requirements of light weight and small diameter. [0003] In the prior art, the cables used by ships are armored with steel wires for the purpose of mechanical protection of outfitting, and must be introduced into wire conduits for laying. Therefore, outfitting operations are time-consuming, and it is necessary to improve the eff...
