SELF-EXTINGUISHING POWER CABLE WITH MICROCAPSULES AND METHOD FOR MANUFACTURING SAME

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 layer and is formed of a treeretardant cross-linked polyethylene compound material; an outer semi-conductive layer which is formed on the insulating layer and is formed of a semi-conductive thermosetting high-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; andan 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. L'invention concerne un câble d'alimentation auto-extinguible à microcapsules et son procédé de fabrication. Le câble d'alimentation auto-extinguible à microcapsules selon un mode de réalisation de la présente invention comprend : une couche conductrice ayant une structure étanche à l'eau d'un fil toronné en cuivre recuit rond et compact rempli d'un composé étanche à l'eau à partir du centre de celui-ci; une couche semi-conductrice interne qui est formée sur la couche conductrice et est formée d'un matériau composite de haute pureté thermodurcissable semi-conducteur; une couche d'isolation qui est formée sur la couche semi-conductrice interne et est formée d'un matériau composite de polyéthylène réticulé retardateur d'arborescence; une couche semi-conductrice externe qui est formée sur la couche d'isolation et est formée d'un matériau composite de haute pureté thermodurcissable semi-conducteur; une première couche étanche à l'eau de fil neutre qui est formée sur la couche semi
