Description

Technical Field

[0001] This utility model belongs to the field of wire and cable technology, specifically relating to a rodent-proof, ant-resistant, wear-resistant polyethylene-sheathed environmentally friendly wire. Background Technology

[0002] Electric wires and cables are wire products used to transmit electrical energy, information, and convert electromagnetic energy. Their structure mainly consists of a conductor core, insulation layer, shielding layer, and outer sheath. Electric wires and cables have a wide range of applications, widely used in construction, power, communications, and transportation. The requirements for electric wires and cables, their application locations, and usage volumes are increasing, and underground cable installation has become a development trend, especially in densely populated areas where the performance requirements for electric wires and cables are becoming more diverse. However, rats and termites often damage the electrical transmission of wires. Rats gnaw on wires, and in southern regions where termites are abundant, they also bore into the wires. Traditional wire and cable sheaths are made of plastic, which usually do not have the function of preventing rodents and termites. Rats and termites can damage the sheath of the wires, which is a shortcoming and needs to be improved. Existing electrical wires lack wear-resistant protection against rodents and ants both inside and outside the sheath during installation. To address this, this application proposes a rodent- and ant-resistant wear-resistant polyethylene sheathed environmentally friendly electrical wire. Utility Model Content

[0003] The purpose of this utility model is to provide a rodent-proof and wear-resistant polyethylene sheathed environmentally friendly wire to solve the problem mentioned in the background art that the wire sheath does not have rodent-proof and wear-resistant protection design inside and outside.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rodent-proof and wear-resistant polyethylene-sheathed environmentally friendly wire, comprising a wire structure including a conductor, a halogen-free low-smoke flame-retardant polyolefin insulation layer, a potting layer, and a rodent-proof polyethylene sheath layer distributed sequentially from the inside out. The conductor is a single-core bare copper conductor, which has good power transmission characteristics. The halogen-free low-smoke flame-retardant polyolefin insulation layer is processed by irradiation cross-linking, which involves irradiating the molecular polymer in the insulation with high-energy particle rays. Compared with other cross-linking methods, irradiation cross-linking results in more stable product performance. It also includes an insulating component, comprising an anti-detachment layer, a wear-resistant mesh layer, and a coating layer fitted on the outside of the rodent-proof polyethylene sheath layer. The wear-resistant mesh layer is located between the anti-detachment layer and the coating layer. Furthermore, it includes a rodent-proof component, comprising a rodent-proof core wrapped around the outside of the coating layer, a separating layer fitted on the outside of the rodent-proof core, and a protective sheath fitted on the outside of the separating layer.

[0005] Preferably, the drug-filling layer has a drug-filling leakage channel.

[0006] Preferably, anti-detachment protrusions are fixed on the outer surface of the anti-detachment adhesive layer, and the mesh diameter of the wear-resistant mesh layer is 1 mm larger than the diameter of the hemispherical anti-detachment protrusions.

[0007] Preferably, the anti-detachment layer, the wear-resistant mesh layer, and the coating layer have the same thickness.

[0008] Preferably, the separator layer and the protective sleeve have the same thickness, and the outer surface of the protective sleeve has diagonal lines.

[0009] Preferably, the separator layer is filled with rodent- and ant-repellent granules.

[0010] Preferably, the rodent-proof core comprises, in order from the inside out, a metal guide wire, a covering sleeve, a rodent-proof filler, and a polyethylene sleeve, wherein the covering sleeve and the polyethylene sleeve have the same thickness.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The design incorporates an anti-derailment layer, a wear-resistant mesh layer, a coating layer, a separator layer, and a protective sheath to physically protect the wire sheath, preventing rodents and ants from damaging the rodent- and ant-resistant polyethylene sheath and chewing through the conductor. Furthermore, the design includes a chemical-filled layer, a rodent- and ant-resistant core, and a separator layer, all incorporating rodent and termite repellents to prevent rats and termites from gnawing and damaging the conductor.
