The invention discloses a safety fireproof cooling wiring conduit. The safety fireproof cooling wiring conduit is characterized by comprising conduits a, a conduit b and a connecting plug, wherein the connecting plug is connected with the conduits a and the conduit b; each of the conduits a and the conduit b comprises a conduit body and a protective cooling layer; each protective cooling layer is arranged on an outer ring of each conduit body; a plurality of wiring fireproof boxes are also connected between the conduits a when the conduits a are connected in parallel; each wiring fireproof box comprises a nitrogen tank and an air faucet; each air faucet is connected with the corresponding nitrogen tank; and an electromagnetic valve for controlling each air faucet to be closed is also arranged on each nitrogen tank. The safety fireproof cooling wiring conduit is simple in structure; and heat generated in the electrifying process of an electric wire in the wiring conduit can be emitted, so that the damage to the electric wire caused by heat accumulation and a fire caused by the heat accumulation are avoided. A blackdamp is generated in the overall conduit in the fire, so that the fire is prevented from spreading to the outside of the conduit; and a relatively big fire is further prevented.
