High Temperature Resistant Magnesium Oxide for MI Mineral Insulated Cable Manufacturing
Fire-resistant cables (often referred to as mineral-insulated or MI cables) utilize magnesium oxide as their insulating material. They offer advantages such as high-temperature resistance, fire resistance, and explosion-proof capabilities; they can operate continuously for extended periods at an ambient temperature of 250°C and withstand short-term operation (up to 30 minutes) under extreme conditions reaching 1000°C.
Mine cable grade Magnesium Oxide for Fire-Resistant Mineral-Insulated MI Cables, high insulation, low moisture absorption, good compaction, factory supply for underground fireproof mine cable insulation filler.
Comprises magnesium oxide products specifically designed for fire-resistant (mineral-insulated) cables. Available in medium- and high-grade specifications to meet varying electrical insulation requirements, these products serve as the primary high-temperature insulating filler material for the manufacture of various rigid fire-resistant and mineral-insulated cables. They are capable of functioning normally in environments with temperatures as high as 1300°C and possess moisture-resistant properties. Particle composition can be customized to meet specific customer requirements.
Magnesium Oxide for Fire-Resistant (Mineral-Insulated) Cables
Custom developed Magnesium Oxide filler for Fire-Resistant Mineral-Insulated (MI) Mine Cables
Excellent high-temperature insulation performance, keeps circuit integrity under fire conditions
Low impurity & low moisture absorption, reduce risk of insulation breakdown during long service
Good compaction & filling property, easy for cable core filling and forming
Strong anti thermal aging performance, stable property under continuous high temperature operation
Strict particle size control, customizable grading for different MI cable production process
Magnesium Oxide for Fire-Resistant (Mineral-Insulated) Cables Advantages 1. High current-carrying capacity and strong overload capability: Compared to plastic-insulated cables of the same cross-section, magnesium oxide cables offer a current-carrying capacity equivalent to that of a cable one or more sizes larger. They can also withstand significant overloads, capable of handling loads up to 100 times the normal rated current.
We manufacture JS-K series electrical grade magnesium oxide powder. This grade is specially formulated as insulation filler for fire-resistant mineral insulated (MI) cables and electric heating cables.
It has outstanding thermal stability and reliable dielectric strength under high temperature fire conditions. The particle gradation is well controlled for cable powder filling process. We support bulk supply for cable manufacturers and can adjust grading according to your production requirements.

2. High mechanical strength: This is primarily due to the specialized materials used; furthermore, even if the cable is crushed by external force to two-thirds of its original diameter, the current-carrying cross-section remains intact.
3. Compact size, light weight, and long service life: Compared to standard cables, the volume is reduced by 60% and the weight by 30%. Its superior corrosion resistance and high mechanical strength ensure a long service life, potentially exceeding 100 years. 4. Excellent grounding performance: The copper sheath provides low grounding resistance, serving as a grounding conductor and eliminating the need for a separate grounding core.
