1,Composition of mineral insulated fire-proof cable structure:
It is composed of copper conductor with high conductivity, inorganic magnesium oxide insulation and seamless copper pipe sheath.
2,The working temperature of mineral insulated fire-proof cables:
The continuous working temperature is 250 C, the melting point of copper can be close to 1083 C in a short time or in an extraordinary period (the melting point of magnesium oxide is 2800 C), and the power supply can last for 3 hours at 950 - 1000 C.
3,Characteristics of Mineral Insulated Fire-proof Cables:
(1) Fire resistance
Copper and magnesium oxide are inorganic materials used in mineral insulated fire-proof cables.The cable will not burn, nor will it support combustion, and can continue to operate near the flame.Copper sheath melts at 1083 ~C, while magnesium oxide insulating material solidifies at 2800 ~C.
(2) High operating temperature
Mineral insulated fire-proof cables can withstand continuous operation temperature up to 250 C.However, in case of emergency, the cable can be operated at a temperature close to the melting point of the copper sheath for a short period of time.
(3) Long life
The inorganic materials used in mineral insulated fire-proof cables can ensure the stability, long service life and fire resistance of cables.
(4) Explosion-proof
The highly compacted insulating material in the mineral insulated fire-proof cable can prevent the passage of steam, gas and flame between the equipment parts connected with the cable.
(5) Small outside diameter
Mineral insulated fire-proof cables are smaller in diameter than other cables with the same rated current.
(6) Waterproof
If the mineral insulated fire-proof cable is completely immersed in water, the mineral insulated fire-proof cable can continue to operate with its seamless metal sheath.
(7) High mechanical strength
Mineral insulated fire-proof cables are durable and can withstand severe mechanical damage without damaging their electrical properties.
(8) High carrying capacity
For cables with the same cross-section, mineral insulated fire-proof cables transmit higher current than other types of cables.At the same time, mineral insulated fire-proof cables can also withstand considerable overload.
(9) Short-circuit fault rating
At the same temperature, the short-circuit fault rating of mineral insulated fire-proof cables is obviously higher than that of other types of cables.
(10) Grounding
For mineral insulated fire-proof cables, independent grounding conductors are unnecessary, because the copper sheath used in the cables has played the role of grounding conductors and can provide excellent low grounding resistance.As far as the grounding skin protection loop (ESR) wiring is concerned, the outer copper sheath can be used as grounding and neutral conductor in the MUN system.
(11) High corrosion resistance
Copper sheath of mineral insulated fire-proof cable has high corrosion resistance. For most devices, it does not need to take additional protective measures.Where copper sheaths of cables are susceptible to chemical corrosion or serious industrial contamination, mineral insulated fireproof cables should be protected by plastic sheaths.
