use:

Applicable to the line with AC rated voltage of 0.6/1KV, which can be used for transmission and distribution. The flame-retardant power cable is suitable for occasions requiring flame-retardant. The fire-resistant power cable is suitable for densely populated areas such as high-rise buildings and large shopping malls.

Use characteristics:

(1) The long-term allowable operating temperature of the cable conductor does not exceed 70 °C, and the short-circuit time (maximum duration does not exceed 5 seconds), the maximum temperature of the conductor cable does not exceed 160 °C.

(2) The ambient temperature when laying the cable should not be lower than 0 °C. When it is lower than 0 °C, it should be preheated first. The minimum bending radius of the multi-core cable is not less than 12 times the outer diameter of the cable. Less than 15 times the outer diameter of the cable.

(3) Conductor DC resistance should meet the requirements of GB/T3956-1997

(4) Power frequency withstand voltage test: 5U+2KV/5min does not breakdown

(5) Flame retardant properties:

The flame-retardant cable can withstand the bundle burning test specified in GB/T18380.3-2001.

The low-smoke low-halogen flame-retardant cable can withstand the bundle burning test specified in GB/T18380.3-2001, and the smoke concentration symbol GB/T17651.1-1998 at the time of combustion, the HCL content in the combustion evolved gas should be mg100mg/g. .
