The correct identification of lines and cables through cable tags plays an important role in maintaining and repairing them. So, what are the requirements for cable tag installation? Introduction to the manufacturer of Shuofang label printer: Cable labeling installation requires clear installation location, labeling content, etc.
Installation position of cable tags:
Aerial parts: Uplead poles, branch poles, joint poles, large reserved poles, and straight poles should be installed every 200 meters.
Pipeline section: Basement, outlet hole, joint manhole, large reserved manhole, branch hole, lead up hole, and straight manhole should be installed with one manhole interval.
Main road and manhole optical (electrical) cable signs
Indoor part: at the upper and lower passages, leading to the rack.
The production of cable tags can be done in various ways, commonly using PVC or aluminum plates for printing. It is necessary to indicate the number of cable cores, the location of the cable, and the construction date.
Requirements for Cable Tagging Content:
What should be noted? What are the requirements for writing?
The signboard should indicate the cable route design number, cable model, specifications, and starting point, and cables used in parallel should have a sequence number. Require clear handwriting that is not easily detached.
Where are cable tags/signs/signs used?
In the swimming area, it is necessary to indicate signs for deep water, shallow water, life-saving equipment, and various studios within the swimming area.
Cable laying construction method:
Flame retardant power cables and fire-resistant power cables are laid through pipes or cable trays. Before laying the power supply, the length of each cable is calculated according to the design and actual path, and each cable reel is arranged reasonably. The cable reel should be rolled in the direction indicated by the arrow on the reel to prevent the cables from getting tangled together due to loosening. After the cable reel is rolled to the predetermined position, a jack should be used to lift the cable reel item onto the cable rack. The cable reel should be placed 50-10mm above the ground and can rotate freely. The cable laying should be done manually or mechanically. When using mechanical traction for cable laying, rollers should be placed every other floor in the shaft, Ensure that the cable does not rub against the support or ground during traction, and the mechanical traction speed does not exceed 15mm/min, leaving a reserved length of about 1m for each cable.
The cables should be arranged neatly along the cable tray without any crossing phenomenon. The cables laid vertically should be fixed every 1.5-2m, and the cable fixing should be done with nylon tape or cable clips. Cable signs should be hung at the beginning and end of the cable and at the joints. The signs should indicate the line number, cable model, specification, and starting and ending points. The signs should have uniform specifications, clear handwriting, and not easily fall off, and be securely hung. The cable terminal head is wrapped with plastic tape, which should be tightly wrapped and have a zero core shape. The core wire is pressed against the wiring nose with a crimping pliers. According to different phases, yellow, green, red, light blue, and black plastic tapes are used to wrap each core wire of the cable to the crimping part of the wiring nose.
After the cable is laid, use a 1000V megger to shake and measure the insulation resistance of each cable. The insulation resistance value should be greater than 10M Ω. After the test, the core wires should be discharged to the ground separately.
Cable listing printer selection:
The fully automatic cable label printer and the single manual cable label printer are currently two major types on the market. The Shuofang Label Machine SP650 and SP600 are representatives of the fully automatic cable label printer, which can automatically send and print labels, with fast speed and efficiency
