As a new type of cable insulation material, silane cross-linked cable material has been widely used in industrial power, building power and other fields due to its excellent high temperature resistance, voltage resistance and environmental protection and energy saving characteristics. Especially in high temperature environment, the stability of silane cross-linked cable material is particularly outstanding, thanks to its unique cross-linking process and material properties.Silane cross-linked cable material uses a cross-linking agent containing silane groups to cross-link the cable insulation material, which improves the high temperature resistance of the material. In high temperature environment, traditional cable materials may suffer from performance degradation due to thermal aging, such as reduced insulation performance and weakened mechanical strength. However, the introduction of silane cross-linking agent in silane cross-linked cable material forms a more stable cross-linked structure inside the material, which can still maintain good stability and anti-aging performance at high temperature. Experiments have shown that silane cross-linked cable material can withstand high temperatures up to 200°C without obvious performance degradation.In addition to high temperature resistance, silane cross-linked cable material also performs well in electrical properties under high temperature environment. Under high temperature conditions, the electrical properties of cables such as insulation resistance and withstand voltage strength tend to decline, which may affect the normal use and safety of the cable. However, silane cross-linked cable material can still maintain good electrical properties at high temperatures by optimizing the cross-linking density and cross-linking structure. This means that in high temperature environments, silane cross-linked cable material can ensure the stability and reliability of power transmission and reduce power failures caused by material performance degradation.In addition, the mechanical properties of silane cross-linked cable material are also relatively stable under high temperature environments. High temperature may cause the softening of cable materials, thereby reducing their mechanical strength and wear resistance. However, silane cross-linked cable material enhances the heat resistance and mechanical strength of the material by forming a stable cross-linked network structure. This allows silane cross-linked cables to maintain good flexibility and tensile strength under high temperature environments, ensuring the safety and reliability of the cables during use.It is worth noting that although silane cross-linked cable material performs well in high temperature environments, its production cost is relatively high and the manufacturing process requires strict requirements. This requires the use of professional production lines and process personnel for production and processing during the production process to ensure the quality and performance of the product. At the same time, the storage stability of silane cross-linked cable material also needs attention, because grafted polyethylene is prone to pre-crosslinking with moisture in the air, which shortens the storage time. Therefore, the storage conditions and time need to be strictly controlled during use to ensure that the performance of the material is not affected.In summary, the stability of silane cross-linked cable material in high temperature environments is outstanding, thanks to its unique cross-linking process and material properties. However, in order to give full play to its performance advantages, it is necessary to strictly control the relevant conditions during production, storage and use. With the continuous development and progress of technology, it is believed that the application prospects of silane cross-linked cable material in high temperature environments will be broader.
