Mineral Insulated Cables, a kind of cables with copper sheath wrapped around a copper conductor core and magnesium oxide powder as an inorganic insulating material to isolate the conductor from the sheath, the outermost layer of which can be selected with appropriate protective sheaths as required. Commonly known as MICC or MI cable. There is a similar cable with metal instead of copper sheath wrapped core and insulation, called mineral insulated metal sheathed cable. MI cable originated in Switzerland in 1896, spread to France in 1934, and began to develop in the UK and the US in 1936. Widely used due to its excellent fire characteristics, including a variety of domestic mineral cable testing standards BS6387, is also used in the United Kingdom. According to the structure can be divided into rigid and flexible. According to the standard can be divided into national standard cable (rigid) and enterprise standard cable (flexible). Rigid mineral cable has the old national standard, as the name suggests, extremely difficult to bend, transport and installation have great limitations. As all the materials of this cable are made of inorganic materials, so it has some advantages that other cables may not have. 1、Fire-resistant In the mineral insulated cable in the application of the two materials copper and mineral insulation is inorganic. This kind of cable will not burn, will not help to ignite, in close proximity to the flame conditions can still continue to operate. The copper sheath melts at 1083℃. 2, high operating temperature Mineral insulated cables can withstand continuous operating temperatures up to 250 ℃. And, in case of emergency, the cable can be close to the melting point of the copper sheath temperature, in a short period of time to continue to operate. 3、Long life Inorganic materials applied in mineral insulated cables can ensure that the cable has stability, long life and fire resistance. 4、Explosion-proof Highly compacted insulating materials in mineral insulated cables prevent vapours, gases and flames from passing between the parts of the equipment connected to the cable. 5、Small outer diameter The diameter of mineral insulated cables is smaller than other cables with the same rated current. 6、Waterproof If the mineral insulated cable is completely immersed in water, with the help of its seamless metal sheath, the mineral insulated cable can continue to operate. 7、High mechanical strength Mineral insulated cables are robust and can withstand severe mechanical damage without compromising their electrical properties. 8、High current-carrying capacity For the same cable with the same cross-section, mineral insulated cables transmit higher currents than other types of cables. At the same time, mineral insulated cables can also withstand considerable overload. 9, short-circuit fault rating At the same temperature, the short-circuit fault rating of mineral-insulated cables is significantly higher than that of other types of cables. 10, grounding For mineral insulated cables, a separate grounding conductor is not required, because the copper sheath used in this cable has played the role of the grounding conductor, which can provide a good low grounding resistance. In the case of earthed sheath circuit (ESR) cabling, the outer copper sheath can be used as the earth and neutral conductor in MEN (Multi Earth Neutral) systems. 11, high corrosion resistance Mineral insulated cable copper sheath has high corrosion resistance, for most installations, it does not need to take additional protective measures. In the copper sheath of the cable is susceptible to chemical corrosion or industrial staining of serious places, should be used to protect the mineral insulated cable wrapped in plastic outer sheath.

Monel-400 alloy is a nickel based alloy, mainly composed of nickel metal and also containing copper metal. It has excellent physical properties such as high strength and high corrosion resistance, while also exhibiting good physical and mechanical properties. Therefore, Monel-400 alloy is widely used in key components in advanced industrial fields such as petrochemical, nuclear, and defense industries. However, due to the small thermal conductivity (21.744W/mK) and linear expansion coefficient (13.86) of monel-400 alloy × 10 ⁻ * K ', therefore it is susceptible to the influence of hot cracking tendency during the welding process. Under local heating and cooling conditions, serious stress and deformation problems may occur, leading to the occurrence of weld solidification cracks in welded joints. Currently, research on the mechanical properties of monel-400 alloy at high temperatures is very limited.   test method The high-temperature tensile test of Monel-400 alloy was carried out on the Gleeble-1500D thermal simulation testing machine. According to the test requirements, the material needs to be processed by molybdenum wire cutting to produce the following specifications: φ six × A 120mm specimen. Before conducting the experiment, it is necessary to ensure that the surface treatment of the specimen is clean and to measure its original diameter. After installing the sample onto the thermal simulator, measure the gauge size between the two clamps. The heating of the sample is achieved by placing the sample into a closed loop of the simulator. Heat the sample at a rate of 10 degrees Celsius per second to 1100 degrees Celsius and hold for 3 minutes, then lower it at a rate of 3 degrees Celsius per second to different test temperatures (600 degrees Celsius, 700 degrees Celsius, 800 degrees Celsius, 900 degrees Celsius, 1000 degrees Celsius, and 1100 degrees Celsius, respectively). At each test temperature, start stretching at a strain rate of 10 negative cubic times per second until the sample fractures. The entire experimental process was completed in a vacuum state. Finally, the fracture surface of the high-temperature tensile specimen was manually sawn off and made into a scanning electron microscope sample. The scanning of the fracture surface was completed under the scanning electron microscope.   Results High temperature tensile performance   The stress-strain curves under tension at different temperatures can be seen in Monel-400 alloy in Figure 2. According to the graph, as the test temperature increases, the strength of Monel-400 alloy significantly weakens and the tensile strength also decreases. For example, the tensile strength of the alloy is 106.49 MPa at a temperature of 600 ℃ and 22.41 MPa at 1100 ℃, indicating that the deformation temperature has a significant impact on the deformation resistance of the alloy. The elastic deformation of the alloy is relatively small, but with the increase of temperature, the plastic deformation increases significantly. The increase from 11.22% to 20.05% at 900 ℃ and the increase in cross-sectional shrinkage from 20.47% at 700 ℃ to 60.05% at 900 ℃ indicate that plasticity becomes better and better with the increase of tensile temperature within this temperature range. As the stretching temperature continues to increase, the plasticity of the alloy shows a decreasing trend, and it basically decreases to the level at 800 ℃ when it reaches 1100 ℃. From the overall curve, it shows a trend of first increasing and then decreasing, indicating that the high-temperature plasticity of Monel-400 alloy first improves with the increase of tensile temperature and reaches a good performance at around 900 ℃. Then, with the increase of tensile temperature, the high-temperature plasticity deteriorates until it approaches the low-temperature level
