Mineral insulated cable is a kind of cable composed of copper conductor and mineral insulating material. The following is a full analysis of mineral insulated cables:

1. Composition and structure

Mineral insulated cable is mainly composed of copper conductor, mineral insulation layer and copper sheath. Among them, the copper conductor is responsible for the transmission of electrical energy, the mineral insulation layer provides electrical insulation, and the copper sheath plays the role of protection and grounding.

2. Characteristics and advantages

1. Fire resistance: Due to the use of inorganic materials as insulating materials, mineral insulated cables have excellent fire resistance. Under fire conditions, the cable can maintain normal operation for a certain period of time, providing valuable time for personnel evacuation and fire rescue.

2. Safety: Mineral insulated cable will not produce toxic smoke and corrosive gases when burning, and the damage to personnel and equipment is small. In addition, it has a strong overload capacity and can withstand large currents without damage.

3. High temperature resistance: Mineral insulated cables can work for a long time in a high temperature environment, and their operating temperature is much higher than that of other types of cables. This makes it particularly suitable for metallurgy, boilers, glass furnaces and other high temperature places.

4. Large current carrying capacity: For cables of the same cross-section, the current carrying capacity of mineral-insulated cables is larger, which can meet the needs of large current transmission.

5. Long life: Due to the use of inorganic materials as an insulating layer, the service life of mineral-insulated cables is longer, reducing the cost of cable replacement and maintenance.

6. Environmental protection: Mineral insulated cable produces less pollution in the production and use process, which meets the current environmental protection requirements.

3. Application scenarios

Because mineral insulated cable has excellent fire resistance, safety, high temperature resistance, large current load and long life, it is widely used in various occasions that require very high cable performance. For example: high-rise buildings, oil platforms, airport terminals, military ships, chemical industry, subway tunnels, iron and steel metallurgy, power plants and aerospace and other fields.

Fourth, construction and installation

The construction and installation of mineral insulated cables must comply with certain codes and standards. During the construction process, it is necessary to pay attention to the bending radius of the cable, the fixing method and the selection of the terminal. In addition, in order to ensure the safe operation of the cable, it is necessary to carry out regular inspection and maintenance work.

5. Development Trend

With the continuous progress of science and technology and the improvement of environmental awareness, the manufacturing technology of mineral insulated cable is also constantly improving and perfecting. In the future, mineral insulated cables are expected to be applied in more fields, and bring more convenient and safe power security to people's lives and work.
