MICC Cable
Mineral Insulated Cables also known as mineral insulated copper clad cable. It is a cable with annealed copper as the conductor, dense magnesium oxide as the insulation and annealed copper tube as the sheath. If necessary, a plastic outer jacket is extruded into the annealed copper sheath. Special requirements are smoke-free and halogen-free occasions. Low smoke and halogen free sheath can be added to the outside.
Fire protection, high current-carrying capacity, resistance to mechanical damage, halogen-free and non-toxic, explosion-proof, waterproof, corrosion-resistant, long service life, high temperature resistance, low cost, small bending radius, termite and rodent bites, protection of the grounding wire, and other copper protection features.
Types of Mineral Insulated Cable
BBTRZ Fire-Proof Mineral Insulated Electrical 4 Cores Cable
BBTRZ is a flexible mineral insulated cable, commonly known as fireproof cable. It can withstand burning for 3 hours at a flame temperature of 950 degrees and a voltage of 1000V without breakdown. BBTRZ cable is the second generation product of mineral cable. In addition to the advantages of fire protection, explosion proof, temperature resistance and large carrying capacity of the first generation rigid (hard) mineral cable, It also has many unique features.

3mm 6mm Mineral Insulated Thermocouple Wire
Mineral insulation is used to insulate thermocouple wires from each other and from the surrounding metal probe sheath. The sheath is filled with a highly compacted magnesium oxide powder that prevents the wires from coming into contact with each other beyond the fixed junction. The high density of the mineral powder gives the thermocouple fast response because it promotes rapid heat transfer between the wires and the sheath. Mineral insulation also helps protect thermocouple wires from environmental damage such as corrosion, prevents electrical interference, and allows the cable to remain flexible while maintaining its mechanical strength.
Type K mineral insulated thermocouples (Nichrome/Nickel Aluminum) are the most common type of thermocouple, offering accuracy and flexibility over a wide range of temperatures.

Related Accessories For MICC Cable
MICC Cable Termination
An intact end installed at the end of a mineral insulated cable, usually including a cap and a stuffing box or a combined end/stuffing box. Each cable requires a terminal.
Ground Lug
When the copper sheath of the cable is used for grounding or the grounding of other electrical equipment connected with the copper sheath of the cable, a grounding sheet is required.
Terminal Blocks
Used to connect conductors and control cabinet terminals or power supplies. It is composed of a press-fit nut, a press-fit oblique block, and a terminal body. There are two types of terminal blocks. One is the press-fit terminal block, which is suitable for connecting cables above 35mm2. Second, the crimping terminal is suitable for the connection of 6-25mm2 cables. Small size cables 4mm2 and below can be without terminal blocks.
Intermediate Connector Accessories
When the cable length is not long enough, it is necessary to use the intermediate connector accessory. It is a device that connects two cables of the same specification into one cable. Cable does not need, heat shrinkable tubing, intermediate connecting terminal, fireproof porcelain column.
