1 Product standard

1.1 GB/T 2951-2008
1.2 GB/T 3048-2007
1.3 BS 6837

2 Use conditions

2.1 Rated voltage  0.6/1V and below the fire protection requirements of the higher level of all  types of buildings fire system;
2.2 Large shopping  malls, hospitals, subways, airports, docks, aerospace, defense engineering,  satellite launch, central control center and other important places;
2.3 Oil, nuclear  power station, metallurgy, chemical industry, mine, kiln and other dangerous,  harsh, high temperature environment

3 Product Features

3.1 Resistant to high temperature

Class A fire protection rating can be 950 ±40 degrees Celsius under high temperature to withstand 90 minutes to maintain normal power, B fire rating at 750±40 degrees Celsius temperature can continue to work for 90 minutes.

3.2 Long production length

Can be customized according to customer length of production, specifications from 2.5mm2 to 400mm2, length based on cable specifications and cable tray capacity of up to 8000 to 800 meters;

3.3 Overload capacity

Due to the use of inorganic material as insulation material, its temperature resistance point is much higher than the polyethylene material , the cable can run at high current and high temperature, so the cable overload capacity is far greater than the ordinary polyethylene insulated cable.

3.4 Long service life

Materials used are inorganic materials, and inorganic stable performance, effectively protect the conductor from oxidation, service life for ordinary polyethylene insulated cables of several times over.

3.5 Convenient installation

3.5.1 Mineral insulated flexible  fireproof cable has good flexibility, can be coiled on the cable tray, to  ensure the safety of transportation in cable;
3.5.2 Installation is convenient,  suitable for all kinds of laying way, can be based on the laying of the scene  need any cutting length;

3.6 Green environmental protection

The product is composed of a refractory insulation layer,  an insulating protective layer, an oxygen separation layer, a non halogen low  smoke outer sheath, and the refractory insulating layer is made of high  insulating refractory mica, strong film and glass fiber. These inorganic  compounds will not burn and will not produce smoke, no more toxic smoke  generated, so it really reached a non toxic and non burning. Is a kind of environmental protection cable .

   Specification Model:  BTTRZ-0.6/1KV-3*240+1*120mm2

5.2 Product Structure

(1) Cable conductor: by multi strand copper wire twisted, with bending  performance and good electrical conductivity;
(2) Insulation: the use of  high temperature resistant, non burning inorganic mineral insulation material  and high temperature insulation protection layer;
(3) Oxygen barrier layer: moisture  and heat can be separated from the heat insulation layer, and the material of the  shell of the oxygen insulation protective layer is formed;
(4) Mineral filled layer:  The product adopts the inorganic mineral material which is developed by  domestic and foreign advanced nanometer technology. has the advantages of fire  prevention, fire resistance, high temperature resistance, heat insulation and  so on.
(5) Outer sheath: The  product is made of non-toxic or low smoke and better plastic material, no  harmful gas is produced when fire occurs, resistance to aging, corrosion  resistance. Has good ageing resistance and mechanical properties;
