A power transmitting cable line with a partition firewall is provided to delay the time in which a fire spreads from one section to the other section. A power transmitting cable line with a partition firewall(100) includes the partition firewall(100), and an inter-cable spacer(200). The partition firewall(100) is composed of firewall units sparsely installed on a line passed by a power transmitting cable(1500) placed on a power transmitting cable support(1200) inside an underground cave(1100). The inter-cable spacer(200) is used as a spacer unit to support the plurality of power transmitting cables(1500) to maintain a space without the direct contact to each other by covering the power transmitting cable(1500). |
