The correct identification of lines and cables by cable tags plays an important role in the maintenance and repair of lines and cables. So, what are the requirements for cable tag installation? Shuofang label printer manufacturer introduction: Cable hanging installation requires clear installation location, hanging content, etc.
Installation location for cable tags:
Overhead section: An overhead pole, branch pole, joint pole, large reserved pole, and straight pole should be installed every 200 meters.
Pipeline section: basement, exit hole, joint manhole, large reserved manhole, diverging hole, leading hole, straight manhole should be installed at intervals of one manhole.
Signs for optical (electrical) cables on dry roads and manholes
Indoor section: 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 optical cable cores, the location of the optical cable, and the construction date.
Requirements for cable tagging content:
What content should be indicated? 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 sequence numbers. Require clear handwriting that is not easily detached. Where are cable tags/labels/signs used?
In swimming facilities, it is necessary to indicate signs for deep water areas, shallow water areas, 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 roll in the direction of the arrow marked on the reel to prevent the cables from becoming loose and twisting together. After the cable reel reaches the predetermined position, use a jack to lift the reel onto the pay off rack. The reel should be 50-10mm above the ground and can rotate freely. Cable laying should be done manually or mechanically. When using mechanical traction to lay cables, rollers should be placed every other floor in the shaft to prevent friction with the support or ground during cable traction. The mechanical traction speed should not exceed 15mm/min, and each cable should be left with a reserved length of about 1m.
The cables should be arranged neatly along the cable tray without crossing. Vertically laid cables should be fixed every 1.5-2m, and the cable fixing ribs should be made of nylon tape or cable clips. Cable signs should be hung at the ends and joints of the cables, indicating the route number, cable model, specifications, and starting and ending points. The signs should have uniform specifications, clear handwriting, 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 connection nose with a crimping tool. According to different phases, yellow, green, red, light blue, and black plastic tape are used to wrap each core wire of the cable to the crimping part of the connection nose.
After the cable laying is completed, the insulation resistance of each cable should be measured with a 1000V megohmmeter, and the insulation resistance value should be greater than 10M Ω. After the test, the core wires should be discharged to the ground separately.
Selection of Cable Tag Printer:
Fully automatic cable label printers and single manual cable label printers are currently the two major types on the market. The Shuofang label printer SP650 and SP600 are representatives of fully automatic cable label printers, which can automatically send and print labels with fast speed and high efficiency. Various specifications of cable labels, cable labels, PVC labels, laminated metal plates, perforated die-cutting labels, silver wire drawing stickers, etc. can be printed, and complex contents such as QR codes, barcodes, electrician symbols, various patterns, logos, tables, etc. can be printed with online settings.
