Description

Technical Field

[0001] The utility model relates to the technical field of high-strength anti-leakage non-metallic suspension wires, in particular to a high-strength wear-resistant, sun-proof, fire-proof, anti-leakage and rust-proof non-metallic suspension wire. Background Art

[0002] In real life, overhead optical cables or electrical cables need to be hung on steel strands, but steel strands have two fatal disadvantages:

[0003] 1) Steel strands are prone to rust, which leads to a decrease in strength. Over time, they will break, causing construction workers hanging on the steel strands to fall, endangering their lives.

[0004] 2) Steel strands are made of metal. When exposed to the sun and rain, the insulation layer of cables or power lines will break and leak electricity, which will cause the steel strands or optical cables to be charged. Once there is a storm, the charged cables, steel strands or optical cables will break and hang down to the ground. If pedestrians pass by, they will be electrocuted, endangering their lives.

[0005] In order to protect the lives of construction workers and pedestrians, it is very urgent to develop a non-metallic suspension wire that has the high strength of steel strands but does not rust or leak electricity to replace steel strands. Utility Model Content

[0006] 1. Technical issues to be solved

[0007] In view of the shortcomings of the existing technology, the utility model provides a high-strength, wear-resistant, sun-proof, fire-proof, leakage-proof and rust-proof non-metallic suspension wire, which has the advantages of high strength, rust-proof and leakage-proof, and solves the problem that steel strands are prone to rust and leakage, causing construction workers to fall and pedestrians to be electric shocked.

[0008] (II) Technical solution

[0009] To achieve the above purpose, the utility model provides the following technical solutions: a high-strength wear-resistant, sun-proof, fire-proof, leakage-proof and rust-proof non-metallic suspension wire, the non-metallic suspension wire is divided into a multi-layer structure: the wire core 1 is woven or extruded with ultra-high molecular weight polyethylene fiber or aramid 1414 fiber. The strength of ultra-high molecular weight polyethylene is 15 times that of steel; the specific strength of aramid 1414 is 5 times that of steel. These two materials have low elongation and are not prone to sag after being tightened, so they can replace steel strands in terms of strength and low elongation. The melting point of ultra-high molecular weight polyethylene is 136°C. When the fire protection requirement is lower than 136°C, the wire core 1 adopts ultra-high molecular weight polyethylene; aramid 1414 can withstand high temperatures of 560°C. When the fire protection requirement is higher than 136°C, the wire core 1 adopts aramid 1414.

[0010] Preferably, the non-metallic suspension wire is woven from the wire core 1 to the outside of the first layer of fireproof wire skin 2 which is made of aramid 1414. Aramid 1414 does not decompose or melt at a temperature of 560° C. and has good fireproof and fire-resistant properties.

[0011] Preferably, the non-metallic suspension wire is woven from the wire core 1 to the second wear-resistant wire sheath 3 which is made of polyester. Polyester has high strength and good wear resistance and light resistance.

[0012] Preferably, the third layer of the non-metallic suspension wire from the wire core 1 to the outside is a sun-proof and waterproof layer 4, and the material of the sun-proof and waterproof layer 4 is one of polyethylene PE, thermoplastic polyurethane elastomer TPU or fireproof glue with strong UV resistance.

[0013] Preferably, all materials of the non-metallic suspension wire are non-metallic insulating materials, so the non-metallic suspension wire will not rust or leak electricity, thus ensuring the safety of construction workers and pedestrians.

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides a high-strength, wear-resistant, sun-proof, fire-proof, leakage-proof, and rust-proof non-metallic suspension wire, which has the following beneficial effects:

[0016] 1. This non-metallic suspension wire has high strength, wear resistance, sun protection, fire resistance, leakage prevention, and rust prevention, and is suitable for long-term outdoor installation.

[0017] 2. The strength of this non-metallic suspension wire is five to fifteen times that of steel wire of the same cross-section.

[0018] 3. The non-metallic suspension wire has low elongation and can avoid sag.

[0019] 4. The insulation of this non-metallic suspension wire will not leak electricity or rust.

[0020] 5. If the non-metallic suspension wire replaces the steel stranded wire, it will not cause construction workers to fall due to rust and breakage, which will not endanger their lives; nor will it cause electric shock accidents to pedestrians due to leakage. BRIEF DESCRIPTION OF THE DRAWINGS
