NOVELTY - The utility model claims a composite household wire, comprising a soft copper conductor core wire, an inner insulating sleeve and an outer insulating sleeve, the periphery of the soft copper conductor core wire is covered with an inner insulating sleeve, and the inner insulating sleeve is added with a graphene heat conducting master batch; In the utility model, by setting the soft copper conductor core wire, the inner insulating sleeve and the outer insulating sleeve form a composite household wire, the inner insulating sleeve is compounded with graphene heat conducting master batch, which can improve the heat conducting performance on the basis of the original inner insulating sleeve, so that the heat generated by the soft copper conductor core wire can efficiently pass through the inner insulating sleeve, avoiding most heat generated by traditional household wire core is hindered by the insulating layer, then, through the inner wall of the outer insulating sleeve is provided with a plurality of radiating passage set along the axial direction, and the section of the radiating passage is V-shaped structure, so that the heat conducted to the inner insulating sleeve and the outer insulating sleeve can be discharged in time, It improves the radiating effect of the household wire.
