For the silver-colored alclad multicore circle flame-retardant flexible electric cable of the invention shown in Fig. 1, manufacturing the method for cable includes：By silver
The step of single electrical core 1 is made in alclad line；Insulation processing is carried out to the single electrical core 1 by described, formation has
The insulation processing step of the insulated wire cores of insulating layer 3；The insulated wire cores to more with insulating layer 3 carry out stranding processing, are formed
The step of cable；And extrude plastics on the cable to form flame retardant sheath layer 5 the step of.Due in manufacture single electrical
During core 1, the cross section of made single electrical core 1 is generally circular, therefore is not usually required to process conductor wire core 1
It is circular conductor wire core 1 into cross section；But if the cross section of manufactured single electrical core 1 is not circle, need
It is circular conductor wire core that conductor wire core 1 is processed into its cross section.
When manufacturing single electrical core 1, the cross section of made single electrical core 1 is generally circular, therefore can
Above-mentioned conductor wire core 1 is processed into the step of circular conductor wire core 1 is in cross section to save.
The step of stranding processing, includes：A plurality of insulated core is twisted using cable-former, forms harness；Then in institute
Wrapped cable separation layer 4 on harness is stated, forms cable.
, will among cable after a plurality of insulated core stranding since the conductor wire core 1 shown in Fig. 1 is circular core
Sizable space occurs, this will reduce the intensity of cable.For this reason, the present invention stranding processing step be additionally included in cable every
