What are the characteristics of mineral-insulated cables? (Part 1)
Hongsheng: Because mineral-insulated cables are entirely composed of inorganic materials (metallic copper and magnesium oxide powder), they themselves cannot cause fires, cannot burn, or support combustion. Copper has a melting point of 1083℃, and the mineral insulation layer also has a melting point above 1000℃.

What are the characteristics of mineral-insulated cables? (Part 2)
Hongsheng: Because the actual normal operating temperature of mineral insulated cables can reach 250℃, IEC60702 stipulates that the continuous operating temperature of mineral insulated cables is 105℃. This is to consider the needs of terminal sealing materials and safety. Even so, its current carrying capacity far exceeds that of other cables, because mineral insulation has a better thermal conductivity than plastic, so at the same working temperature, the current carrying capacity is greater.

Introduction to mineral cables
Hongsheng: Mineral-insulated cable, a type of cable with a copper conductor core wrapped in a copper sheath, and using magnesium oxide powder as an inorganic insulating material to isolate the conductor from the sheath. An appropriate protective sheath can be selected for the outer layer as needed. Commonly known as MICC or MI cable. A similar cable uses metal instead of a copper sheath to wrap the core wire and insulating material, called mineral-insulated metal-sheathed cable.

What should be paid attention to during the transportation and storage of mineral cables?
The main difference between mineral-insulated cables and other ordinary cables lies in the cross-linking treatment of specially formulated inorganic compounds using high-energy electron beams (radiation) generated by high-power electron accelerators during production, enabling the cables to withstand operating temperatures as high as 125℃. Mineral cables significantly improve fire resistance while maintaining flexibility.

How to install mineral cables?
Mineral-insulated cable is a type of cable where copper conductor cores are encased in a copper sheath, with magnesium oxide powder used as an inorganic insulating material to isolate the conductor from the sheath. The outermost layer can be a suitable protective sheath as required.

Performance and application prospects of mineral-insulated cables
Mineral-insulated cables are widely used in modern power distribution systems. Their fire resistance, durability, safety, reliability, ease of installation, and cost-effectiveness are unmatched by traditional power cables. A mineral-insulated cable is an inorganic cable. The outer layer is a seamless copper sheath, and a dense magnesium oxide insulation layer is provided between the sheath and the metal core. Depending on the application, it can be divided into power distribution cables, heating cables and heating elements, thermocouple cables and compensation cables, and special cables, among which power distribution cables are the most commonly used in practice.

Advantages of mineral-insulated cables
Because all the materials of mineral insulated cables are inorganic, it has some advantages that other cables do not have. 1. Fire resistance From 010 to 1504, the two materials used, copper and mineral insulation, are inorganic. This cable will not burn or support combustion, and can continue to work under conditions close to flames. Copper sheaths melt at 1083. 2. High operating temperature Mineral insulated cables can withstand continuous operating temperatures up to 250. In addition, in emergencies, the cable can continue to operate for a short time at temperatures close to the melting point of the copper sheath. 3. Long service life Mineral

Difference between mineral-insulated cables and ordinary cables
Mineral insulated cable intermediate connectors are used, and cable end terminals are used at the ends. The terminals have terminal boards that can be connected to the busbars and terminal boards of the equipment. Mineral insulated cables (MI cables), also known as magnesium oxide cables or fire-resistant cables in China, are copper-core copper-sheathed cables using magnesium oxide powder as insulation material. Mineral insulated cables consist of two inorganic materials: copper conductors, magnesium oxide, and copper sheathing. The differences between mineral insulated cables and ordinary cables are compared from the following aspects: I. Cable components

What are the advantages of mineral-insulated cables?
Mineral Insulated Cable Advantages: 1. Higher operating temperature: Mineral insulated cables can withstand continuous operating temperatures up to 250°C. Furthermore, in emergencies, the cable can continue to operate for a short time at temperatures approaching the melting point of the copper sheath (copper sheath melts at 1083°C). 2. Long service life: The inorganic materials used in mineral insulated cables ensure the stability and fire resistance of the cable, and ensure the service life of the cable. 3. Explosion-proof: The high-density insulation material in mineral insulated cables prevents steam, gases and flames from passing between equipment parts connected to the cable.

Mineral-insulated cable: Advantages of mineral-insulated cable
All materials of mineral insulated cables are inorganic, thus having advantages that other cables do not have. 1. High operating temperature: The continuous operating temperature of mineral insulated cables is as high as 250℃. In addition, in emergencies, the cable can continue to operate for a short time at a temperature close to the melting point of the copper sheath (copper sheath melts at 1083℃). 2. Long lifespan: Inorganic materials suitable for mineral insulated cables ensure the stability and fire resistance of the cable, guaranteeing its lifespan. 3. Explosion-proof: The highly compacted insulation material in mineral insulated cables prevents steam and gas from entering.
