Mineral cable structure:
Mineral cables are composed of high conductivity copper conductors, mineral (magnesium oxide) insulating materials, and seamless copper tube sleeves. When the cable is used in situations that are corrosive to copper, an outer layer of anti-corrosion protection outer sheath is added. .
1. Cable conductor: The conductor is made of metal copper with high conductivity.
2. Insulation layer: Inorganic minerals that are resistant to high temperature and non-combustible are used as insulation materials.
3. Isolation layer: made of inorganic mineral material.
4. Outer sheath: It is made of low-smoke and non-toxic plastic material with good anti-corrosion properties.
Mineral cable application:
1. General lighting, emergency lighting, fire alarm, fire-fighting electrical circuit, emergency elevator and lifting equipment circuit, computer room control circuit, trunk branch distribution system circuit, dual power supply control circuit, smoke emission and ventilation circuit, large power circuit , Potentially dangerous explosion lines and other places, generator room transmission lines.
2. High-rise buildings, petrochemicals, airports, tunnels, ships, offshore oil platforms, aerospace, iron and steel metallurgy, shopping malls, parking lots and other occasions.
Mineral Cable Model:
1. BTTZ: Due to the use of seamless copper tube metal sleeve + magnesium oxide mineral insulation, it is also known as rigid mineral insulated cable; models include BTTVZ, BTTYZ, BTTQ, BTTVQ, BTTYQ, etc. BTTZ cables do not have five cores, because copper tubes can be used as The ground wire is used, and the fire performance is the best among all models.
2. YTTW: It is composed of braided copper sheath + inorganic mineral insulation. It is an improved model of BTTZ and belongs to flexible mineral insulated cables. Models include YTTWY, YTTWV, BTTRZ, RTTZ, BTTW, BTTE, BTWTZ, etc.
3. NG-A (BTLY): It adopts aluminum tube metal sheath and inorganic mineral insulation. Models are: BTLV, BTWGLY, TBTRZL, TBTRZLY, BTMMRZ, etc.
4. BBTRZ: Fireproof cable without metal sheath in mineral cable. Models are: BTWYZ, BTYRZ, etc.
