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...

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.

Description

technical field [0001] The invention belongs to the field of cables, in particular to a waterproof fluorescent cable for underground tunnels. Background technique [0002] At present, with the development of society and economy, the consumption of cables is increasing rapidly, and the quality requirements for cables are also constantly improving. For example, in the mining work of coal mines, due to the dark underground roadway, ordinary cables are almost invisible or unclear, which makes the installation and maintenance of cables inconvenient, and there is a great hidden danger to safe mining. Another example is that due to the long-term humidity of the working environment, traditional cables cannot meet the waterproof requirements of actual work. As long as it meets the requirements, it can meet the actual use of the cable. Contents of the invention [0003] In order to overcome the defects of the above-mentioned prior art, the object of the present invention is to pro...
