The most valuable thing in network transmission is information, not network equipment, but a small cable. Do you have fire awareness? Today, the WING CABLE INDUSTRIAL CO.,LTD申博体育 will tell you about the importance of cable fire prevention.
It can be seen that information is non-renewable, once lost, it will never be, so people do everything possible to back up data through various means, through a stable network to transmit data, and place them in a safe place. People gradually turn the integrated wiring system to the direction of resisting external invasion and avoiding external hazards. Therefore, fire-proof cables are considered as the most important part of sailing cables.
When refractory cables are used in dense cable tunnels, cable sandwiches, or in inflammable places such as oil pipes and oil depots, class A refractory cables should be selected first. In addition to these circumstances, and when the number of cable configuration is small, the type B refractory cable should be selected.
WING CABLE INDUSTRIAL CO.,LTD should tell you that fire-resistant cables are mostly used as power supply circuits for emergency power supply, requiring normal operation in case of fire. Because the ambient temperature rises sharply during the fire, in order to ensure the transmission capacity of the line and reduce the voltage drop, the section of the refractory cable should be enlarged at least one gear for the circuit with a long power supply line and a strict limit on the allowable voltage drop.
Refractory cables should not be used as high temperature cables. In order to reduce the probability of failure of cable joints in fire accidents, it is suggested that the number of joints should be minimized in installation to ensure the normal operation of cable joints in fire. If branch wiring is needed, fire protection should be done for the joints.
