Electrical wiring + correct direction of wire number tube = good habit of electrical wiring! Do you have it

in the wiring process of electrical instruments, the wire number tube is an essential and important part. Mature power distribution technology is certainly inseparable from line number tube, but in the process of practical application, many people do not pay attention to it, so that the wiring is not standardized, which brings trouble to troubleshooting and maintenance

common sense about wire number tube: do you know the direction of wire number tube

number tube is also called line number tube. It can be said with certainty that there is a certain direction for fetching number tube

01 correct direction of the number tube

1, number 4. Service life: when the code tube is horizontal or placed on both sides of the wiring terminal, the text direction of the number tube reads from left to right

2, when the number tube is vertical or placed on the upper and lower sides of the terminal block, the text direction of the number tube is read from bottom to top

3, as shown in the figure: when the number tube is at different angles, the text direction depends on the phase angle

for example, when the casing direction is at 1 and 3 corners, the text direction is read from bottom to top

for example, when the bushing direction is 2 and 4 due to the fading angle of the characteristic, the text direction is read from top to bottom

correct use of number tubes

1. If the terminal strips or electrical equipment are of different sizes and arranged unevenly, the number tubes should be aligned with each other and arranged in rows

2, when developing high-performance cast magnesium alloy, high strength and toughness deformed magnesium alloy and preparation technology, low-cost magnesium alloy and processing technology at the end of the conductor, the number tube shall be close to the side of the terminal

3, when the wires are wired in rows on the terminal or electrical equipment, when the size of the terminal strip or electrical components is the same, the number tube shall be close to the terminal side

03 function of wire number tube

1. During the wiring process of electrical instruments, it is necessary to set wire number tube. The wire number tube will clearly indicate the wire number or equipment circuit number, so that the electrical maintenance personnel can quickly and accurately see where the line comes from and where it goes during the maintenance process

Dongsheng new materials Co., Ltd. will continue to work hard

2. Regular wiring, line number tube and drawing line number are one-to-one corresponding, and all lines of the electrical cabinet are fully equipped. If there is no line number, it will greatly increase the difficulty and time of troubleshooting

I believe that many electrical maintenance masters know that in complex control systems, the role of wire number control is almost irreplaceable and very important
