Disclosed is a self-extinguishing power cable with microcapsules and a method for manufacturing the same. The self-extinguishing power cable with microcapsules according to one embodiment of the present invention comprises: a conductive layer with a watertight structure of a compact-round annealed copper stranded wire filled with a watertight compound from the center thereof; an inner semi-conductive layer which is formed on the conductive layer and is formed of a semi-conductive thermosetting high-purity compound material; an insulating layer which is formed on the inner semi-conductive layerand is formed of a tree retardant cross-linked polyethylene compound material; an outer semi-conductive layer which is formed on the insulating layer and is formed of a semi-conductive thermosettinghigh-purity compound material; a first neutral wire watertight layer which is formed on the outer semi-conductive layer and is a semi-conductive swellable tape; a concentric neutral wire which is formed on the first neutral wire watertight layer and is an annealed copper wire; a second neutral wire watertight layer which is formed on the concentric neutral wire and is a swellable tape; and an outer skin layer which is formed on the second neutral wire watertight layer and is formed of a PVC or polyethylene material, wherein microcapsules filled with an activator for extinguishing a flame is applied to at least one of the first neutral wire watertight layer and the second neutral wire watertight layer.
