Description

Technical Field

[0001] This utility model relates to the field of rubber-sheathed cable technology, specifically to an environmentally friendly irradiated rubber-sheathed cable. Background Technology

[0002] Rubber-sheathed cables are a type of flexible, portable cable consisting of multiple strands of fine copper wire as conductors, encased in rubber insulation and a rubber sheath. Generally, they include general-purpose rubber-sheathed flexible cables, welding machine cables, submersible motor cables, radio equipment cables, and photographic light source cables. Rubber-sheathed cables are widely used in various electrical equipment, such as household appliances, electric machinery, electrical installations, and portable power cords for appliances. They can be used in both indoor and outdoor environments. Based on the mechanical forces they are subjected to, they are classified into light-duty, medium-duty, and heavy-duty types. Environmentally friendly irradiated rubber-sheathed cables typically refer to cables treated with environmentally friendly materials through irradiation cross-linking to improve their heat resistance, aging resistance, and abrasion resistance.

[0003] A search revealed a patent publication (CN209487176U) disclosing a weather-resistant irradiated cross-linked rubber-sheathed flexible cable for tidal flats. This cable uses a blend of EPDM and polyolefin as its outer sheath, replacing the EPDM and CP / CPR of traditional rubber-sheathed cables and the XLPE and PVC of plastic power cables. This results in a cable with environmentally friendly materials, a compact structure, and stable performance, offering promising market prospects. The puncture-resistant layer, constructed from cross-woven glass fibers, enhances the cable's puncture resistance, preventing damage from sharp objects and ensuring safety. While this patent application improves puncture resistance, it reduces flexibility and weather resistance, potentially affecting the cable's lifespan under certain environmental conditions. Therefore, we propose an environmentally friendly irradiated rubber-sheathed cable. Utility Model Content

[0004] The purpose of this invention is to provide an environmentally friendly irradiated rubber-sheathed cable to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly irradiated rubber-sheathed cable, comprising a cable wire, the outer side of which is wrapped with an insulation layer, a packaging layer is provided on the outer side of the insulation layer, a filler layer is filled between adjacent insulation layers and packaging layers, a heat insulation layer is wrapped on the outer side of the packaging layer, a flame retardant strip is wrapped on the outer side of the heat insulation layer, an armor is wrapped on the outer side of the flame retardant strip, and an outer protective layer is wrapped on the outer side of the armor.

[0006] Preferably, by adding an insulation layer and flame-retardant tape to the outside of the packaging layer, the cold resistance and heat resistance of the cable can be improved, and the armor and outer protective layer work together to ensure the protective performance of the cable.

[0007] The cable is made of multi-strand twisted copper wire, and the outer protective layer is made of polyvinyl chloride.

[0008] Preferably, the outer protective layer is made of polyvinyl chloride, which can effectively reduce the impact of ultraviolet rays on the cable material and extend the service life of the cable. At the same time, the use of multi-strand twisted copper wire braided cable can improve the flexibility of the cable.

[0009] The filling layer is made of polyethylene foam.

[0010] Preferably, the filling layer is made of polyethylene foam to fill the gap between the insulation layer and the packaging layer, which can improve the cable's flexibility and bending resistance. The inner side of the outer protective layer is coated with a polytetrafluoroethylene (PTFE) coating, and the thickness of the PTFE coating after spraying is 0.5 mm.

[0011] Preferably, spraying polytetrafluoroethylene can enable the cable to work stably for a long time in environments with high radiation intensity and chemical corrosion, thereby improving the cable's service life.

[0012] The outer protective layer consists of two layers: an inner layer of carbon fiber reinforced plastic and a layer of glass fiber reinforced plastic. The outer protective layer is 5 mm thick, and the carbon fiber reinforced plastic and glass fiber reinforced plastic layers are of the same thickness.

[0013] Preferably, the combination of carbon fiber reinforced plastic layer and glass fiber reinforced plastic layer not only improves the protective strength and corrosion resistance of the outer protective layer, enabling the cable to operate stably under long-term radiation environment, but also makes the materials lighter, reducing the weight of the cable.

[0014] Among them, the gaps between the outer protective layer, armor, flame retardant strip, heat insulation layer, insulation layer and packaging layer are coated with softener and plasticizer to assist in the surface coating.

[0015] Preferably, the use of softeners and plasticizers for auxiliary spraying between layers can improve the cable's flexibility, protective performance, and abrasion resistance.

[0016] This utility model has at least the following beneficial effects: By adding an insulation layer and flame-retardant tape to the outside of the packaging layer, the cold and heat resistance of the cable can be improved. The armor and outer protective layer work together to ensure the cable's protective performance. The insulation layer reduces the impact of external temperature on the internal cable when the temperature is too low, ensuring normal transmission. The flame-retardant tape prevents the internal cable from being burned by flames in the event of an external fire, avoiding breakage caused by flames and further improving cable stability. Furthermore, the filling layer uses polyethylene foam to fill the gaps between the insulation layer and the packaging layer, improving the cable's flexibility and bending resistance. The outer protective layer, woven with layers of glass fiber reinforced plastic and carbon fiber reinforced plastic, not only improves the protective strength and corrosion resistance of the outer protective layer, allowing the cable to operate stably under long-term radiation, but also uses lighter materials, reducing the cable's weight. This ensures the cable's protective effect while further improving its cold and heat resistance. Additionally, the use of multi-strand twisted copper wire braiding improves the cable's flexibility.

[0020] Please see Figures 1 to 3 : Example

[0021] This utility model provides a technical solution: an environmentally friendly irradiated rubber-sheathed cable, comprising a cable 6, with an insulation layer 5 wrapped around the outer side of each cable 6, a packaging layer 8 disposed outside the insulation layer 5, and a filler layer 7 filling the space between adjacent insulation layers 5 and packaging layers 8. An insulation layer 4 is wrapped around the outer side of the packaging layer 8, a flame-retardant tape 3 is wrapped around the outer side of the insulation layer 4, an armor 2 is wrapped around the outer side of the flame-retardant tape 3, and an outer protective layer 1 is wrapped around the outer side of the armor 2. The insulation layer 5 is used to prevent adjacent cables 6 from interfering with each other and causing short circuits. The packaging layer 8 is used to securely package the cable 6, preventing it from loosening. Layer 7 is used to fill the gap between the packaging layer 8 and the insulation layer 5 to prevent the adjacent cable 6 from overheating during long-term operation, which could lead to overheating and short circuits. The insulation layer 4 is used to reduce the impact of external temperature on the internal cable 6 when the temperature is too low, ensuring the normal transmission of the cable 6. The flame-retardant tape 3 is used to prevent the internal cable 6 from being burned by flames in the event of an external fire, avoiding the problem of the cable 6 breaking due to flame burning, and further improving the stability of the cable. The armor 2 is used in conjunction with the outer protective layer 1 to ensure the protective performance of the cable 6. In addition, the cable 6 uses multi-strand twisted copper wire braid, which can improve the flexibility of the cable.

[0022] The cable 6 is braided with multi-strand twisted copper wire, and the outer protective layer 1 is made of polyvinyl chloride. The use of polyvinyl chloride in the outer protective layer 1 can effectively reduce the impact of ultraviolet rays on the cable material and extend the service life of the cable.

[0023] The filling layer 7 is filled with polyethylene foam. The filling layer 7 uses polyethylene foam to fill the gap between the insulation layer 5 and the packaging layer 8, which can improve the flexibility and bending resistance of the cable.

[0024] The inner side of the outer protective layer 1 is coated with a polytetrafluoroethylene coating 10. The thickness of the polytetrafluoroethylene coating 10 after spraying is 0.5 mm. By spraying polytetrafluoroethylene, the cable can work stably for a long time in high radiation intensity and chemical corrosion environment, thereby improving the service life of the cable.

[0025] The outer protective layer 1 consists of two layers: an inner layer of carbon fiber reinforced plastic and a outer layer of glass fiber reinforced plastic. The outer protective layer 1 is 5 mm thick. The carbon fiber reinforced plastic and outer layer of glass fiber reinforced plastic are the same thickness. The carbon fiber reinforced plastic and outer layer of glass fiber reinforced plastic work together to improve the protective strength and corrosion resistance of the outer protective layer 1, enabling the cable to operate stably under long-term radiation. At the same time, the materials are also lighter, reducing the weight of the cable.

[0026] The outer protective layer 1, armor 2, flame retardant tape 3, heat insulation layer 4, insulation layer 5, and packaging layer 8 are all coated with softener and plasticizer to improve the flexibility of the cable and enhance its protective performance and abrasion resistance.
