Ашигт малтмалын тусгаарлагчтай кабелийн шинж чанар, хэрэглээ юу вэ?

Ашигт малтмалын тусгаарлагчтай кабель нь эрдэс тусгаарлагчтай кабелийг МИ кабель гэж нэрлэдэг, утас болгон ашигладаг, дотоодын заншлыг магнийн ислийн кабель эсвэл галд тэсвэртэй кабель гэж нэрлэдэг.

It is by the mineral material magnesium oxide powder as insulation copper core copper sheath cable, зэс дамжуулагчаар эрдэс тусгаарлагчтай кабель, магнийн исэл, copper sheath of two inorganic materials.

Mineral insulation cable composition MICC cable is a cable with annealed copper as a conductor, dense magnesium oxide as insulation, and annealed copper tube as a sheath.

Хэрэв шаардлагатай бол, outside the annealed copper sheath extrusion wrapped a layer of plastic outer sheath, special requirements for smoke-free and halogen-free occasions can be added outside a layer of low-smoke halogen-free sheath.

Advantages of Мineral Insulated Cболомжтой

Fire-resistant

The two materials used in the mineral-insulated cable, copper and magnesium oxide, are inorganic.

This cable will not burn, nor will it contribute to combustion, and can continue to operate near flame.

The copper sheath melts at 1083 °C, while the magnesium oxide insulation material cures at, 2800 °C.

High Operating Temperature

Mineral-insulated cables can withstand continuous operation at temperatures up to 250 °C.

Гэсэн хэдий ч, in emergencies, the cable can continue to operate at temperatures close to the melting point of the copper sheath for short periods.

The diameter of mineral insulated cables is smaller than other cables with the same current rating.

Long Life Span

The inorganic materials applied in mineral-insulated cables ensure stability, long life, and fire resistance.

Explosion Resistance

The highly compacted insulation in mineral-insulated cables prevents the passage of vapors, gases, and flames between the parts of the equipment connected to the cable.

Small Outer Diameter

The diameter of mineral-insulated cables is smaller than other cables with the same current rating.

Waterproof

Mineral-insulation cables can continue to operate if they are completely submerged in water with the help of their seamless metal sheath.

Өндөр механик хүч чадал

MICC cables are robust and can withstand severe mechanical damage without compromising their electrical properties.

High Load Capacity

For the same cross-section, mineral-insulated cables carry higher currents than other types of cables. Үүний зэрэгцээ, mineral-insulated cables can withstand considerable overloads.

Grounding

For metal-insulated cables, a separate grounding conductor is not required, as the copper sheath used in this cable already acts as a grounding conductor and provides an excellent low grounding resistance.

For grounded sheath circuit (ESR) wiring, the outer copper sheath can be used as a ground and neutral conductor in MEN (multiple ground neutral) системүүд.

High Corrosion Resistance

The copper sheath of mineral-insulated cables is highly resistant to corrosion and for most installations, it does not require additional protection measures.

Where the copper sheath of the cable is susceptible to chemical corrosion or heavy industrial contamination, the mineral-insulated cable should be protected with a plastic sheath.

Mineral Insulated Cболомжтой Ттөрлийн

Common mineral cables are BTTZ, NG-A, BTLY, YTTW, BBTRZ, and other models, and are divided into flexible MICC cables and rigid mineral insulated cables.

So what are the uses of these mineral-insulated cables?

BTLY, YTTW, BBTRZ, гэх мэт. belong to flexible mineral insulated cable, while BTTZ belongs to rigid mineral insulated cable, so let’s take a look at their uses!

Flexible mineral insulated bbtrz cable

The main material consists of mineral compounds, with high-temperature resistance, гал, explosion-proof characteristics, шатаахад хялбар биш, can work under the flame temperature of 950 °C 1000V, the conductor structure is also relatively soft, easy to bend, applicable to a variety of laying methods.

Flexible mineral-insulated yttw cable

The yttw cable is composed of a copper core conductor as well as a layer protective sheath, it is a new type of fireproof cable, the cable also has a fireproof layer on the outside, so the fireproof performance is also high.

There are flexible, high-pressure resistance characteristics in addition to the characteristics of not being suitable for moisture, тавихад хялбар, and widely used in basic industrial and civil construction.

Flexible mineral insulated btly cable

Mineral btly cable is composed of metallic copper and magnesium oxide powder, as the melting point of copper is 1083℃, and the melting point of magnesium chloride is 2800℃, so the cable itself will not cause fire, nor will it help to ignite.

The working temperature can reach 1000℃, with the characteristics of fire resistance, усны хамгаалалт, зэврэлтэнд тэсвэртэй, long life, аюулгүй байдал, өндөр температурт тэсвэртэй, гэх мэт.

Suitable for special grade buildings, first-class buildings and super high-rise buildings should use mineral insulated cables.

Rigid mineral-insulated bttz cable

BTTZ is a rigid mineral insulated cable, all composed of inorganic materials, so there is no insulation aging, with has high-temperature resistance, is fireproof, тэсрэлтэнд тэсвэртэй, non-combustible, with high load capacity, small outer diameter, high mechanical strength, үйлчилгээний урт хугацаа, болон бусад шинж чанарууд.

Normal working temperature can reach 250℃, with high fireproof performance, widely used in nuclear power plants, металлурги, нисэх онгоцны буудлууд, өндөр барилгууд, and other places.

Mineral Cболомжтой Уsage

MICC cables are widely used in nuclear power plants, металлурги, chemical industry, уурхайнууд, сансар огторгуй, өндөр барилгууд, нисэх онгоцны буудлууд, terminals, underground railways, and other places with concentrated passenger flow, to protect the fire pumps, fire elevators, important loads, emergency evacuation instructions, as well as anti-smoke systems and other important fire-fighting equipment with electricity.

Once installed and laid, mineral cables can be used forever.

Mineral cable is composed of high conductivity copper conductor, mineral (магнийн исэл) insulation material, and seamless copper tube sheath, when the cable is used for copper corrosion occasions, the outer layer of another layer of corrosion protection outer sheath.

Mineral cable has the advantages of being fireproof, waterproof and explosion-proof, non-combustible, smokeless, non-toxic, and fire-resistant.

Утаа багатай, галогенгүй кабелийн бүрээс нь халаах үед утаа бага ялгаруулдаг, галоген агуулаагүй термопластик эсвэл термос материалаас бүрддэг..

Low-smoke halogen-free cable and mineral-insulated cable are two different kinds of cables.

The following cable treasure to share with you the утаа багатай галогенгүй кабель and mineral insulated cable from the material, characteristics, voltage, and use of the comparison.

Cable Material Distinction

Галогенгүй утаа багатай кабель: галогенгүй (Ф, Cl, Br, I, At) does not contain lead and other environmental substances of the rubber insulation.

Mineral insulated cable: магнийн исэл (inorganic material) sheath and metal wire core between a layer of tightly compacted magnesium oxide insulation layer.

Cable Performance Characteristics

Low smoke and halogen-free cable: no halogen gas is released during combustion, low smoke concentration, and the permitted working temperature is up to 150℃, and the cable achieves the effect of negative combustion through irradiation cross-linking process, which is in line with the national standard of environmental protection cable.

Mineral insulated cable: will not burn, will not help combustion, does not produce harmful gases, in the flame temperature of 1000 ℃ can maintain normal power for 3 цаг, strong electrical stability, long life, load capacity large.

Different rated voltage and usage of cables

Low smoke and halogen-free cable: suitable for нэрлэсэн хүчдэл 450/750V and below, with halogen-free, бага утаа, flame retardant requirements and high safety and environmental protection requirements of places. Such as high-rise buildings, станцууд, метро, нисэх онгоцны буудлууд, эмнэлгүүд, libraries, гэр бүлийн байшингууд, зочид буудлууд, эмнэлгүүд, оффисын барилгууд, сургуулиуд, худалдааны төвүүд, болон бусад хөл хөдөлгөөн ихтэй газрууд.

Mineral insulated cable: suitable for rated voltage 0.6/1KV and below, with flame retardant, гал, soft requirements, and high-temperature requirements of the place. Such as petrochemical, нисэх онгоцны буудлууд, хонгилууд, хөлөг онгоцууд, offshore oil platforms, сансар огторгуй, steel metallurgy, shopping centers, parking lots, болон бусад тохиолдлууд.
