The application of magnesium oxide in fire-resistant cables

Cables are already very common in our daily lives,and fire-resistant cables are one of the many types of cables.Generally speaking,cables with fire-resistant performance are called fire-resistant cables.

            Cables are already very common in our daily lives,and fire-resistant cables are one of the many types of cables.Generally speaking,cables with fire-resistant performance are called fire-resistant cables.Fireproof cables are composed of inorganic substances such as metal copper and magnesium oxide powder.They themselves do not cause fires and cannot burn or support combustion.Due to the melting point of copper being 1083℃and magnesium oxide being 2800℃,this type of cable can still maintain good electrical performance in extreme environments such as high temperatures and fires,and has very important application value.It is a truly fire-resistant cable.

         Specifically,the reason why magnesium oxide is so important for fire-resistant cables is mainly due to the following reasons:

           1.Improve the fire resistance performance of cables

            Magnesium oxide itself is a difficult to ignite and non flammable substance.Adding it to mineral insulation materials can effectively improve the fire resistance performance of cables.

            2.Improve the high-temperature resistance performance of cables

            Magnesium oxide can exist stably at high temperatures and has high heat resistance.Adding it to mineral insulation materials can improve the high-temperature resistance of cables,enabling them to continue working in harsh high-temperature environments.

             3.Improve the insulation performance of cables

             The insulation performance of mineral insulation materials is crucial for the safe operation of cables.Adding an appropriate amount of magnesium oxide can improve the insulation performance of mineral insulation materials,reduce the dielectric constant of the insulation layer,reduce the dielectric loss of cables,and increase the insulation resistance of cables.

             4.Improve the mechanical and corrosion resistance of cables

             Magnesium oxide has high hardness and compressive strength.Adding it to mineral insulation materials can increase the mechanical strength and compressive strength of cables,and improve their durability.In addition,magnesium oxide also has certain acid and alkali resistance,which can effectively prevent cable corrosion by liquids and increase its service life.

              Therefore,in the manufacturing process of mineral insulated fire-resistant cables,adding an appropriate amount of magnesium oxide can help improve the overall quality of fire-resistant cables,thereby ensuring their good performance in complex environments such as high temperatures and fires.

              It is worth noting that in the process of adding magnesium oxide,it is necessary to strictly control the amount of magnesium oxide added to avoid adding too much or too little,which may lead to unstable cable quality or safety hazards.In addition,when selecting magnesium oxide products,it is advisable to choose high-quality magnesium oxide materials to ensure that the added mineral insulation materials have stable performance and quality.Zehui Magnesium has always provided high-quality industry-specific magnesium oxide products for cable manufacturers,and can provide customized solutions according to the different processes and formulas of different manufacturers,ensuring the highest compatibility with products from various cable manufacturers.
