Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a high temperature resistant cable. Background Art

[0002] Cables are important tools for transmitting electrical energy, but in high temperature environments, due to electrical properties, material properties and other reasons, cables are prone to problems such as insulation aging, short circuits, and softening and hardening of wires, which may cause the cables to fail to function properly.

[0003] The existing cables have the problem that high temperature will cause the temperature of the cable conductor to rise. The conductor of the cable is the transmission channel of the electric current. When the temperature rises, the resistance of the conductor will increase, causing more heat to be generated when the current passes through, which will further increase the temperature of the conductor, forming a vicious circle. If the temperature of the conductor is too high, it may cause cable overload and short circuit and other faults, and even cause a fire. Secondly, high temperature weather will also damage the cable insulation material and outer sheath materials, which are easy to soften and accelerate their aging under the influence of high temperature environment. Once these materials are damaged, the cable will have problems such as leakage and short circuit. In severe cases, it may cause equipment damage or personal safety accidents.

[0004] Therefore, a high temperature resistant cable is proposed to solve the above problems. Utility Model Content

[0023] See also Figure 1As shown, a high temperature resistant cable, the material of the inner sheath layer 6 is a silicone-based synthetic material, the silicone sheath can operate continuously in the temperature range of 200°C to 300°C, and the material of the outer sheath layer 7 is set to nickel alloy, and the nickel alloy can maintain mechanical and chemical stability at a temperature of up to 1000°C; wherein the inner sheath layer 6 is a silicone-based synthetic material, silicone can still maintain good elasticity and insulation properties at high temperatures, and the outer sheath layer 7 uses nickel alloy as the sheath material, nickel alloy has excellent high temperature performance and corrosion resistance, and is suitable for use in extreme environments.

[0024] Working principle: First, the outer wall of the copper alloy conductor 1 is provided with a groove 2, which can be used to fill the silver-plated layer 3. As the cable is an important part of power transmission and communication, it bears great responsibility. In order to ensure the normal operation of the cable in high temperature weather, the silver-plated layer 3 is provided to improve its conductivity at high temperature, and the nickel-plated layer 4 is provided to improve its corrosion resistance at high temperature. In addition, since the continuous high temperature weather in summer will affect the cable, it is necessary to take some measures to protect the safety of the cable. For this purpose, an insulating high-temperature resistant layer 5 is provided, wherein the material of the first layer 501 is set as polytetrafluoroethylene, which has the properties of corrosion resistance, chemical resistance, wear resistance, high toughness and strength, and the material of the filling layer 502 is set as a mineral insulating material, which can withstand continuous operating temperatures of up to 250°C, and will not burn or support combustion, and can continue to operate under conditions close to flames, etc., wherein the filling layer 502 is set at equal angles with respect to the inside of the first layer 501, and the material of the second layer 503 is set as silicone to improve the temperature resistance of the cable;

[0025] Next, an inner sheath layer 6 is arranged on the outer wall of the insulating high temperature resistant layer 5. The inner sheath layer 6 is made of a synthetic material based on silicone. The material can still maintain good elasticity and insulation performance at high temperatures. The silicone sheath can continue to operate in the temperature range of 200°C to 300°C, and some specially formulated silicones can even withstand higher temperatures. At the same time, an outer sheath layer 7 is arranged on the outer wall of the inner sheath layer 6. The outer sheath layer 7 uses nickel alloy as the sheath material.

The nickel alloy can maintain mechanical and chemical stability at temperatures as high as 1000°C. Finally, a connecting glue 8 is arranged on the outer wall of the outer sheath layer 7. 8 The outer wall is provided with a fireproof layer 9. Since the continuous high temperature will increase the working pressure of the cable, and the cable temperature will be damaged when it is too high, its working performance will be damaged, and insulation breakdown will easily occur. After this phenomenon occurs, the insulation layer of the cable will be damaged, and the conductor inside will be easily exposed. If it contacts the conductor between other cables, a short circuit will occur, and it will catch fire, causing explosions and fires with extremely serious consequences. If this situation really occurs, it will not only affect the normal power supply of the local area, but also cause huge economic losses and possible casualties. For this reason, a fireproof layer 9 is provided, and its material is glass fiber to improve the performance of the cable in the event of a fire.
