NS type fireproof cable and manufacturing system thereof

The invention provides an NS type fire-resistant cable and a manufacturing system of the NS type fire-resistant cable. The manufacturing system of the NS type fire-resistant cable comprises outer layer laying units, traction equipment and a shaping module, wherein the outer layer laying units are sequentially laid and manufactured outside the cable; the traction equipment is used for fixing and pulling a cable core to drive the cable core to sequentially pass through the different outer layer laying units; the shaping module is used for respectively shaping and rolling different laying layers of the cable core; and the temperature control module is arranged on the shaping module and is used for controlling the contact temperature of the shaping module and the cable. The shaping module can perform accurate shaping operation on each coating layer of the cable, so that the production efficiency is improved while the quality of the cable is ensured. 本发明提供了一种NS型耐火电缆及其制作系统，与现有技术比较，本发明的NS型耐火电缆的制作系统包括依次将各敷设制作于电缆外部的外层
