1. First, you need to print the heat shrinkable number tube: use professional printing equipment to print the line number or logo content, so that it can be marked once and permanently identified, which will be more reliable. The blank number tube needs to be printed with the required content and line number before use. The printed content corresponds to the electrical circuit line number in the drawing.

   You can also put a blank number tube on the cable, and then use a marker to write the required content or wire number by hand. This marking method is not recommended because the marking will not achieve the desired firmness and the marking will fade.

2. Distinguish the number tubes corresponding to the cables: After printing the number tubes, install the corresponding number tubes according to the line numbers. For example, for the "input signal" cable, put the number tube printed with "input signal" on the cable. . It is very convenient and quick to use. Just put it on and shrink it with a little heat to complete the marking effect.

   Precautions for using the number tube:

The correct use of heat-shrinkable number tubes must achieve a basic point, which is to facilitate reading. The direction of the printed content of the number tube must comply with our usual reading habits.

   When the heat shrinkable number tube is installed horizontally or placed on both sides of the terminal block, the reading direction of the printed content is from left to right;

   When the heat shrinkable number tube is oriented vertically or placed on the upper and lower sides of the terminal block, the reading direction of the printed content is from bottom to top;

   For electrical cabinets with a lot of wiring, when wiring wires in rows, the heat shrinkable number tubes should be close to the side of the terminals, aligned with each other, and arranged neatly.

   It can be seen that the use of heat shrinkable number tubes is very simple. It only requires two steps to complete. First, print the number tubes, then put them on the wires and heat and shrink them to complete the identification of the cables. Duwai Company provides printing number tube services.
