Although the flame-retardant cable is not as good as the fire-resistant cable, it can continue to run smoothly without being burned out under the high temperature of the fire, but it can prevent the spread of the fire, keep the fire within a limited range, keep other various equipment, and avoid causing greater damage. Loss. So which is better, flame retardant cable or fire resistant cable? Let's find out together.
Aerial cables have the main advantages of high power supply reliability, good power supply security, convenient erection and maintenance, and reasonable economy. The use of overhead cables greatly reduces the occurrence of various dangerous accidents, ensures personal safety, and reduces the maintenance and repair work of the line. What is the difference between overhead cables and buried cables? Let Zhengzhou Jinshui Cable Group take everyone to understand.
When selecting wires for overhead lines, aluminum stranded wires that meet national standards should be used, and single-strand aluminum wires, unstrand wires and iron wires are prohibited. When selecting the cross-section, it is necessary to take into account the mechanical strength of the wire to avoid uncertain factors such as wire breakage due to weather changes and external forces.
One of the important items of electrical engineering includes the connection technology of control cables. During the whole connection process, the screen closing and grounding of the city cable are essential construction links. Next we will describe in detail why the control cable screen needs to be grounded?
Both YJV cable and YJY cable are relatively commonly used cables. Many people do not know the difference. Let me explain in detail today. Let's distinguish it from the naming method of the cable. YJ is cross-linked polyethylene insulation, and V single-label PVC sheath at the back.
