I. Overview of Cables:

High temperature fire-resistant control cables are suitable for signal detection in high temperature environment with AC rated voltage of 300/500 or less. Especially suitable for fire protection and security system protection circuit control and power transmission line.

II. Implementation criteria

GB9330-88

3. Use characteristics:

1. AC rated voltage: U0/U 450/750V;

2. Maximum operating temperature: flame retardant PVC insulation and sheath 70 ~105 ~C;

Fluoroplastics insulation and sheath at 200 C and 260 C;

The insulation temperature of crosslinked polyethylene is 90 C.

Low smoke halogen-free flame retardant polyolefin 70 C;

Low smoke halogen-free flame retardant crosslinked polyolefins at 90 ~125 ~C.

3. Minimum ambient temperature: flame retardant polyvinyl chloride sheath fixed laying - 40 C, non-fixed laying - 15 C;

Fluoroplastics insulation and sheath fixed laying - 60 C, non-fixed laying - 20 C;

4. Fire resistance

According to IEC 331, flame temperature 750 C, combustion time 3h, cooling time 12h, additional rated voltage, additional 3A current

According to GB12666.6-A, flame temperature 950-1000 C, combustion time 90min, additional rated voltage 3A current

According to GB12666.6-B, flame temperature 750-800 C, combustion time 90 min, additional rated voltage 3A current

5. Installation and laying temperature of cable should not be lower than 0 and fluoroplastic sheathed cable should not be lower than - 25 C.

6. The recommended permissible bending radius for laying: non-armoured cables should be no less than 6 times of cable outer diameter, armoured cables should be no less than 12 times of cable outer diameter, and fluoroplastic insulated and sheathed cables should be no less than 8 times of cable outer diameter.
