Embodiment

[0030] The sheath material adopts the extrusion process of low temperature resistant elastomer sheath material, extruded with 65 type extruder equipment, and adopts a double screw screw with a compression ratio of 25:1:

[0031] Process flow: preparation - mold matching - heating - adjusting mold - extrusion control - completion

[0032] 1) Preparation: equipment inspection, electrical inspection, turn on the power of the equipment, prepare production tools and product process cards;

[0033] 2) Die matching: the inner diameter of the core d = the outer diameter of the strand + (0.20~0.50) mm, the inner diameter of the mold sleeve = the nominal outer diameter of the finished product + (-0.1 ~ 0.1) mm; after the mold is determined, install the filter screen, Filter plate and die head, and feed after confirming that there is no debris in the hopper;

[0034] 3) Heating: After turning on the heating power, set the temperature of each section according to the extruded material: Z...

Abstract

The invention relates to a towline cable and a manufacturing process thereof. The towline cable structurally comprises a conductor, an insulator, a tensile core, an inner sheath and an outer sheath. The radiation ethylene propylene rubber insulator is arranged on the periphery of the conductor, the low temperature resistant elastic body inner sheath is arranged on the periphery of the radiation ethylene propylene rubber insulator, and the flexible polyurethane outer sheath is arranged on the periphery of the inner sheath. The manufacturing process is that a tinned copper wire is stranded by a wire cable stranding machine to server as the conductor, an extruder device is utilized to extrude the environment-friendly radiation ethylene propylene rubber insulator on the outside of the conductor, the stranding machine is utilized to strand high-strength tensile fibers, flexible polyvinyl chloride (PVC) is extruded by the extruder device on the outer layer to serve as the tensile core, then a cabling machine is utilized to strand an insulation wire core and the tensile core together, and the extruder device is utilized to extrude low temperature elastic body sheath materials to serve as the sheaths. The cable has the advantages of high mechanical strength, flexibility, high abrasion resistance, aging resistance, cracking resistance, mould resistance, moisture resistance and acid-base corrosion resistance, is flexible under the low temperature condition and suitable for special environments such as weapons, electronics, high-level civil use.

Description

technical field [0001] The invention relates to a towline and its preparation process. The towline cable can be adapted to work in narrow and harsh environments such as weapons, electronics, and high-end civil use, and has the advantages of high mechanical strength, high wear resistance, aging resistance, crack resistance, mildew resistance, moisture resistance and It is resistant to acid and alkali corrosion, and has excellent mechanical and electrical properties. Background technique [0002] At present, there is no relevant towline cable standard in the cable industry. Based on the reference to GB / T 5023-2008 PVC insulated cables with rated voltage of 450 / 750V and below, the relevant properties of the product in special environments are added: ① Cold resistance; ②Salt spray resistance; ③Moisture resistance; ④Aging resistance; It is formulated according to the special requirements of users, fully considers its applicability and reliability, fully considers special require...
