Environment-friendly flame-retardant power cable for construction engineering and production process

The invention discloses an environment-friendly flame-retardant power cable for construction engineering. The cable comprises a plurality of annularly distributed cables, and a flame-retardant layer,an oxygen barrier layer, a support layer, a buffer layer and a protective layer which are sequentially wound on the outer sides of the plurality of cables; each cables comprises circular cable cores,corrugated cable cores and an insulating layer; the multiple corrugated cable cores are annularly and evenly distributed in the radial direction of the circular cable cores; the multiple layers of corrugated cable cores are arranged, and the corrugated cable core on the outermost layer is sleeved with the insulating layer. According to the invention, the plurality of corrugated cable cores are stranded on the outer sides of the circular cable cores, so that the width of the cable can be reduced while the load is satisfied, the resistivity of the cable cores is reduced, and the weight per unitlength is reduced. 本发明公开了一种
