Abstract

The invention discloses a waterproof fluorescent cable for an underground roadway. The waterproof fluorescent cable for the underground roadway comprises main cable cores, a nylon non-woven fabric taped covering layer, a silicone rubber insulation layer, a nickel plated copper braid shielding layer and a fluorescent sheath, wherein the main cable cores are wrapped in the nylon non-woven fabric taped covering layer, the silicone rubber insulation layer, the nickel plated copper braid shielding layer and the fluorescent sheath sequentially, the three sets of main cable cores are evenly wrapped in the nylon non-woven fabric taped covering layer in an extruding mode, a grounding wire core is arranged in the silicone rubber insulation layer, a waterproof layer is arranged between the nickel plated copper braid shielding layer and the fluorescence sheath, and the waterproof layer is composed of a waterproof outer layer, a waterproof inner layer and a water absorbing layer. The cable is good in conductive performance, resistant to dragging, winding, breakage, weather and high temperature, the cable is mainly applied to underground roadways, the cable is waterproof, resistant to moisture and high in shielding performance, meanwhile, the cable can give out fluorescent light, the position of the cable can be recognized easily, and the cable can be laid and maintained easily in a dark place.

Example Embodiment

[0011] Such as figure 1 As shown, a waterproof fluorescent cable for underground tunnels includes a main core 1 and a nylon non-woven fabric wrapping layer 3, a silicone rubber insulating layer 5, and a nickel-plated copper wire braided shielding layer 6, which are sequentially wrapped around the main core 1 outside. The fluorescent sheath 8 is characterized in that: the main cores 1 are in three groups, and they are evenly squeezed inside the nylon non-woven fabric wrapping layer 3, and the silicone rubber insulating layer 5 is also wrapped with a grounding core 4 A waterproof layer 7 is provided between the nickel-plated copper wire braided shielding layer 6 and the fluorescent sheath 8. The waterproof layer 7 is composed of a waterproof outer layer, a waterproof inner layer and a water-absorbing layer.

[0012] The main core 1 is composed of a copper conductor, a fluororubber insulation layer and an aluminum foil braid layer wrapped outside the copper conductor, and the copper conductor is stranded with 99.9999% oxygen-free annealing and tinned ultra-fine soft copper wire. (GB/T3956-2008) Production of the sixth super soft copper conductor structure.

[0013] The fluorescent sheath 8 is made of an alkali-free glass fiber cloth with a fluorescent agent and a ceramicized polyvinyl chloride material. It emits fluorescence in a dark environment, which is conducive to identifying the position of the cable, and is convenient for the cable to be in the dark Laying and maintenance.

[0014] The grounding core 4 is made of annealed copper-aluminum alloy wire with a silver-plated surface and twisted to the right, with a diameter of 0.75 mm.

[0015] The allowable bending radius of the cable is 16 times the outer diameter of the cable; the cable is allowed to be cyclically bent 8 million times; it can withstand AC 50HZ, 3.5Kv/5min voltage without being broken down.

[0016] The above are the embodiments of the present invention, so any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention are all included in the scope of the present invention.
