Mineral insulated cable applications? Micc cable characteristics
Mineral insulated cable has many advantages in fire protection, can be divided into rigid and flexible two kinds, then when should use mineral insulated cable?

1.characteristics of mineral insulated cable BTTZ

a.High operating temperature: the continuous operating temperature of mineral insulated cable is up to 250℃. However, in an emergency, the cable can be operated for a short time at a temperature close to the melting point of the copper sheath.
b.Fire resistance: copper and magnesium oxide, two materials used in mineral insulated cables, are inorganic. This kind of cable does not burn, also does not support combustion, in the condition that approaches flame still can continue to operate;
c.Explosion-proof: highly compacting insulating material in mineral insulated cable, which can prevent steam, gas and flame from passing between the equipment parts connected with the cable;
d.Long service life: the inorganic material used in mineral insulated cable can ensure the stability, long service life and fire resistance of the cable;
e.Waterproof: if the mineral insulated cable is completely immersed in water, the mineral insulated cable can continue to operate with the help of its seamless metal sheath;
f.Small outer diameter: the diameter of mineral insulated cable is smaller than other cables with the same rated current;
g.High mechanical strength: mineral insulated cable is durable and can withstand severe mechanical damage without damaging its electrical properties;
Characteristics of mineral insulated cable BTTZ
h.High current carrying capacity: for cables of the same section, mineral insulated cables transmit higher current than other types of cables. At the same time, mineral insulated cable can withstand considerable overload.
i.High corrosion resistance: the copper sheath of mineral insulated cable is highly corrosion resistant and does not require additional protection measures for most devices. Where the copper sheath of the cable is vulnerable to chemical corrosion or serious industrial contamination, the mineral insulated cable should be protected by a plastic sheath.
j.High short-circuit fault rating: at the same temperature, the short-circuit fault rating of mineral insulated cables is significantly higher than that of other types of cables.
k.Good grounding: for mineral insulated cables, a separate grounding conductor is not required as the copper sheath used in this cable already ACTS as a grounding conductor, providing excellent low grounding resistance.

2.Application scope of mineral insulated cable

a.public buildings, places of public entertainment, expo center, hospitals, schools, Banks, department stores, airports, bus stations, metallurgical industry, shipping industry, and other places of high temperature electric line, nuclear power, military industry, chemical industry, brick of offshore oil Wells, oil refinery and petrochemical industry, subway, tunnel, underground square.
b.according to wintek electric provide mineral insulated cable engineering case shows that these places use mineral insulated cable, 54 meters in high-rise buildings, fire protection system main railway electricity transmission, high-risk chemical plant, electric shaft system, diesel generating sets, parking lot system, transformer system, emergency lighting, underground tunnel system, etc.
