What are the fire-retardant measures for wires and cables?

Fire-retardant measures for cable and wire include:
(1) Apply fireproof paint on the cable surface.
(2) Wrap the parts of the cable that need to be flameproof with fireproof tape.
(3) The holes where the cable passes through the wall, the bottom of the plate, and the shaft are tightly sealed with refractory materials to avoid the spread and spread of high-temperature smoke when the cable is on fire, which will cause the fire area to expand.
(4) Set up heat-resistant and fire-proof panels between the cable layers, segmented partition walls and fire doors to prevent the cable layers from combusting and expand the fire.
(5) Wrap the cable with a heat-insulating and flame-resistant material. When the cable is on fire, the wrapped cable is isolated from the fire by the heat-insulating and flame-resistant material to avoid burning. If the cable itself catches fire, the lack of oxygen in the bandage can cause the fire to self-extinguish and prevent the fire from spreading outside the bandage.
(6) Equipped with necessary fire fighting equipment and facilities. Common fire extinguishing equipment can be used to extinguish the fire of overhead cables, but automatic or remote control fire extinguishing devices, such as 1301 fire extinguishing devices, water spray fire extinguishing devices, etc., should be installed in cable interlayers, shafts, trenches and tunnels.
