Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of copper wire sheathing materials, in particular to a high temperature resistant semi-conductive copper wire sheathing material. Background Art
[0002] Semi-conductive copper wire sheath is an important component used to protect wires and cables in electrical systems. It is usually composed of multiple layers of materials, including an inner conductive layer, a waterproof layer, an outer aluminum film sheath and a flame retardant coating. The inner conductive layer of the semi-conductive copper wire sheath is usually made of copper or copper alloy, which has good conductivity and is used to transmit current and signals. The waterproof layer is located between the inner conductive layer and the outer aluminum film sheath. It uses materials such as polyurethane and silicone to prevent moisture intrusion and protect internal electrical components from the impact of humid environments.
[0003] Existing semi-conductive copper wire sheaths usually have a flame retardant layer inside, but the flame retardant layer is set in the layer, resulting in the outermost side of the semi-conductive copper wire sheath not having good high temperature resistance. The outer aluminum film sheath may be affected when subjected to high temperature, causing the aluminum film material to become brittle at high temperature, reducing its high temperature resistance. In the event of a fire, the outermost aluminum film sheath may not be able to effectively resist high temperature and flames, because the flame retardant layer blocks the heat from being conducted to the external aluminum film layer, thereby weakening the fire protection effect. The outer part of the conductive copper wire sheath loses its protective performance under high temperature conditions, which may affect the safety of the entire electrical system and increase the risk of fire.

[0020] The working principle and use process of the utility model are as follows: when it is necessary to make a semi-conductive copper wire sheath body 1, the inner conductive layer 2 is the innermost layer, and the inner conductive layer 2 is made of copper alloy material. The copper alloy has good electrical conductivity and can effectively conduct current to ensure the normal operation of electrical components. The outer side of the inner conductive layer 2 is wrapped with an intermediate insulating layer 3, and the intermediate insulating layer 3 is made of silicone material. The silicone material has good insulating properties and can effectively prevent the leakage of current between electrical components to ensure the safe operation of the electrical system. The material of the intermediate insulating layer 3 has good chemical stability and can resist the erosion of chemical substances such as acids and alkalis to ensure the long-term stable operation of electrical components.
[0021] The outer surface of the intermediate insulating layer 3 is evenly wrapped with a supporting reinforcement layer 9. The glass fiber has excellent mechanical strength and can effectively support electrical components and reduce the possibility of deformation and damage. The glass fiber has good wear resistance and can resist friction and wear in the external environment during long-term use, thereby extending the service life of the semi-conductive copper wire sheath 1. The glass fiber is also light, which also helps to reduce the overall weight of the semi-conductive copper wire sheath. The inner part of the supporting reinforcement layer 9 is evenly distributed with supporting ribs 4. The supporting ribs 4 can effectively enhance the structural stability of the semi-conductive copper wire sheath, reduce the possibility of deformation and damage, ensure the normal operation of electrical components, extend their service life, and reduce the frequency and cost of replacement and maintenance. The supporting ribs 4 are evenly distributed inside and can provide comprehensive support and protection, making the semi-conductive copper wire sheath more stable when subjected to stress.
[0022] The outer surface of the supporting reinforcement layer 9 is installed with a flame retardant layer 5, which is made of flame retardant polyurethane material. Flame retardant polyurethane has good flame retardant properties. Flame retardant polyurethane has super high temperature resistance, can effectively prevent the spread of fire, and protect internal electrical components from flames and smoke. The flame retardant layer 5 material usually also has the characteristic of inhibiting smoke generation, which can reduce harmful gases generated during fire and protect personnel from smoke damage. The outer surface of the flame retardant layer 5 is installed with a waterproof layer 8, which is made of acrylic material. Acrylic acid has good waterproof properties and can effectively prevent moisture from penetrating into the interior of the semi-conductive copper wire sheath, protecting internal electrical components from moisture damage. The waterproof layer 8 is coated with an aluminum film protective layer 7, which is made of aluminum foil material. The aluminum film protective layer 7 has good anti-corrosion properties and can effectively prevent water oxidation, corrosion, etc. from eroding electrical components and prolonging their life. The service life of the semi-conductive copper wire sheath is long, and the aluminum film sheath 7 is relatively light and will not add too much weight, which is helpful to realize the lightweight design of the semi-conductive copper wire sheath. The aluminum film sheath 7 is easy to process and install, and can meet the requirements of different shapes and sizes, thereby improving production efficiency. A flame retardant coating 6 is also sprayed on the surface of the aluminum film sheath 7. The flame retardant coating 6 is made of flame retardant epoxy resin coating. The flame retardant epoxy resin coating is resistant to high temperature. The flame retardant epoxy resin coating has good flame retardant properties and can effectively inhibit the spread of flames, prevent the occurrence and spread of fire, and improve the safety of the semi-conductive copper wire sheath in the event of a fire. The flame retardant epoxy resin coating usually has good weather resistance and can resist the influence of external environment such as ultraviolet rays, high temperature, and humidity, thereby extending the service life of the semi-conductive copper wire sheath. The flame retardant epoxy resin coating can provide the semi-conductive copper wire sheath with a uniform and beautiful appearance, thereby enhancing the overall texture and appearance appeal of the product.
