Product Description
Mineral insulated cable is a kind of cable in which copper conductor core is wrapped with copper sheath and magnesium oxide powder is used as inorganic insulating material to isolate conductor and sheath. The outermost layer can choose appropriate protective sheath as needed. Commonly known as MICC or MI cable. A similar type of cable is called a Mineral insulated metal sheathed cable (Mims cable) that wraps the core and insulation with a metal sheath instead of copper.
At present, China's common 3 types of fireproof cable
Copper core copper sheathed magnesium oxide insulated cable: it is composed of solid copper rod, magnesium oxide insulation and seamless copper pipe sheath. (without outer sheath BTTZ, BTTQ, with outer sheath BTTVZ, BTTVQ, WD-BTTYZ)
Flexible inorganic mica with mineral insulation cable: it is composed of copper stranded wire, fluorine mica with insulation and copper belt with longitudinal wrapped continuous welding sheath. (without outer sheath YTTW, RTTZ, with outer sheath YTTWV, WD-YTTWY, RTTZV, WR-RTTZY, BTTW, BTTRZ).
Flexible isolation type aluminum sheath mineral insulation cable (NG-A, BTLY) : it is composed of copper strand, gold mica tape insulation, seamless aluminum tube sheath, oxygen insulation layer filling, isolation refractory layer, low smoke halogen-free sheath.
The above three types of cables, the best fire performance is the BTTZ series, which is the only internationally recognized mineral insulation cable, it uses high conductivity of solid copper conductor as conductor, highly compressed powder magnesium oxide (MgO) as insulation, seamless copper tube as sheath, Modern building wiring cables and cables used in special industries (metallurgy, chemical industry, petroleum, etc.) are made by special technology.
Advantages of fireproof cable
The life of conventional use can reach one hundred years;
Do not burn, do not support combustion, do not release toxic gas, zero combustion energy;
Continuous working temperature up to 250ºC, short-term working temperature up to 1083ºC;
Excellent fire resistance, the cable can be reused after fire;
The cable terminal and the intermediate coupling are equipped with the cable, the cable fire reliability is enhanced;
In a fire, the cable can withstand extremely high temperature, falling impact of objects, fire water spray;
Cable can be used in high temperature occasions;
Waterproof, moistureproof, oil proof, corrosion resistance;
No aging, cable performance is extremely stable;
The metal sheath of the cable can be used as the ground circuit;
Excellent mechanical strength, good bending performance, can be used for complex structure, small space installation environment;
Because of the particularity of cable structure, its carrying capacity is large;
Small cable diameter, easy installation, low comprehensive cost, cable without pipe-piercing protection;
Good explosion-proof performance, excellent anti-nuclear radiation performance;
Excellent electromagnetic shielding performance and EMC performance;
Can prevent the animal bite.
