Features and uses:

This product is suitable for AC rated voltage 450 / 750V and below subway, high-rise buildings, shopping malls, theaters, power stations, chemical factory, city square and other utilities on the properties of flame retardant cable for high occasions. Cable halogen-free low smoke and low halogen low smoke characteristics, when there is a fire, spread speed slow, low smoke density, high visibility, emissions of harmful gases small for evacuation. Combustion gas corrosion, but also to avoid the damage of equipment, low halogen, halogen free characteristics, making cable material ageing resistance and resistance to ultraviolet light and other radiation performance is greatly improved, so as to prolong the service life of the cable.

 

Main technical index:

 

1. cable should withstand the ambient temperature of the power frequency voltage test 5min, 3kV does not breakdown.

2. the transmission rate of the cable should be in accordance with the following table

Cable diameter D (mm) transmission rate (%) ≥ the outer diameter of the cable D (mm) transmission rate (%) ≥D>40705<D≤105010<D≤4060D≥540

3. Non flame retardant (flame retardant properties) of cables: should be adopted the B class in the test. Single cable vertical burning test halogen acid gas release.

4. The halogen acid gas release quantity should in compliance with IEC754-15

5. pH and conductivity of the combustion gas, with IEC754-2 PH≥4.3, electrical conductivity ≤10μS/mm

 

Production range:

Section (mm2):0.5, 1, 1.5, 2.5, 4, 6, 10, 16, 25,

 

Main use:

 

The flame retardancy of the product is superior, burning smoke little, no corrosive gas escape. It is widely used in nuclear power station, subway station, telephone switchboard and computer control center, high-rise buildings, hotel, and broadcast television, important military facilities, oil platforms and other personnel focused, low air density places.
