Fire-resistant cable is mainly used in emergency power supply to the user of fire equipment, fire alarm equipment, ventilation and smoke exhaust, guide line lights, emergency power socket, the elevator for the emergency power supply circuit.
Small make up to tell you, fire-resistant cable installation considerations.
1, when fire-resistant cable used for cable populated in the Tailfeng lan cable
tunnels, cable interlayer, or inflammable places near tubing, oil depot, fire-resistant cable shall, first of all, choose A category.
Despite the situation, and the less number of cable configuration, should choose B type fireproof cables.
2, fire-resistant cable mostly used as emergency power supply circuit, the normal work of the requirements of fire.
Due to the fire when the environment temperature has risen sharply, to ensure the transmission capacity of lines, lower pressure drop, long for the power supply circuit and the circuit of the voltage drop strictly limit allowed, fire-resistant cable should be at least one.
3, fire-resistant Tailfeng lan cable cannot be used as a high temperature resistant cable.
4, in order to reduce Tailfeng lan cable joint failure probability in fire accident, should try to reduce the amount of joint in the installation, to guarantee the normal work of the lines in the fire.
If you need to do to branch connection, deal with joint completes the fire prevention.
