The invention relates to a power cable for a solar photovoltaic power distribution cabinet. The power cable comprises a plurality of copper alloy conductive wires and a plurality of protective sleeves, wherein the copper alloy conductive wires are arranged in parallel; each copper alloy conductive wire is enwrapped by the protective sleeve, and the protective sleeve comprises the following components: polybutylene terephthalate, ethylene propylene rubber, isoprene rubber, ethylenediamine tetramethylenephosphonic acid, dimethyl formamide, cottonseed oil, phosphate, eucalyptus oil, bronopol, garlic oil, tea polyphenol, ceramic powder, zeolite powder, lead oxide powder, sodium carbonate, calcium phosphate powder, vermiculite powder, dolomite powder, honey, polyethylene wax, triethylene glycol bis(2-ethylhexanoate), p-cresol, polyacrylonitrile fiber, polyoxyethylene oleate, vinyl benzene, cobalt isooctoate, sodium ricinate, a sulfenamide accelerator, p-toluenesulfonic acid and lauryl methacrylate. The power cable is soft in texture, wear-resistant, high temperature-resistant, safe and reliable, and has relatively excellent flame-retardant, acid-resistant, alkali-resistant, mildew-proof and antibacterial performance.
