▼ Advantage:
1) fireproof performance
The cable is of excellent fire resistance. It conforms to the highest fire resistance rating 950℃ 3h specified in British Standard BS6387. Besides, it can withstand water spray and mechanical impact. As a result, it is full beyond the fire resistance requirement 750℃ 90min specified in GB/T19216.21 and GB/T19216.11.
2) longer continuous length
The length of single core and multi-core cable can meet the demands of power supply. The continuous length of each cable can be more than 1000m.
3) larger cross-section area
The maximum cross-section area of single core cable can be 630mm². The maximum cross-section area of multi-core cable can be 300mm².
4) flexibility
The cable can be coiled in cable trays. bending radius≤20D(D means the outside diameter of cable)
