3 Identification mark system for wires and cables
Wires and cables should use numbers, letters, symbols, colors or their combination as identification marks. Letters should use Latin letters in uppercase and lowercase. The markings for wires and cables should comply with the provisions of relevant standards of my country. 3.1 Digital identification marks
3.1.1 Wires and cables can use numbers as identification marks, and the combination of letters and numbers can be used to indicate supplementary identification marks. Letters B, D, I, O, and Q that may cause confusion with numbers should be omitted. 3.1.2 Each number (or combination of letters and numbers) mark can only be used once in a machine, and the identification marks at both ends of each wire or cable should be the same. When a wire or cable passes through an electrical device, its identification mark should be changed (when modifying numbers or words). 3.1.3 The marking carrier should be the same color; all identification numbers (or words and numbers) should be the same color. The color of the marking carrier should be significantly different from the color of the marking. It should be confirmed that it meets or is close to a certain color specified in GB6995.2. 3.2 Color identification mark
3.2.1-Wires and cables can be marked with colored insulation, colored rings or labels at both ends. Different colors should indicate special marks. Colored wires, insulation rings or labels that contrast with the base color can be used as supplementary marks. When using labels for marking, the carrier of the label should be the same color.
3.2.2 The marking color should be a color that can be confirmed to meet or be close to the provisions of GB6995.2. Under external environmental conditions, colors that are not easy to maintain for a long time or that cause misunderstandings before changing with external colors and brightness should not be used. 3.2.3 Load-bearing wires or cables should use red as an identification mark. For example, the wire (or rope) connecting the battery to the main switch, main fuse, generator, and motor should be red. 3.3 Identification mark of grounding electrode
3.3.1 Regardless of whether color marking or digital marking is used, the insulated core of the wire and cable used for the grounding electrode should be black as the identification mark, and the black wire and cable shall not be used for other purposes. 3.3.2 In the electrical system diagram, the grounding electrode can be marked with a symbol or the number 0. The use of this mark is unified. It is only applicable to the grounding node of the conductor. Approved by the Ministry of Machinery and Electronics Industry on May 28, 1992 and implemented on January 1, 1993
3.4 ​​Marking position
JB/T6037-1992
The marking position should make the marking characters, ribbons, labels and colors easy to see, and the marking should be located within 150mm of the end of the wire and cable. The marking ribbon and label can also be copied along the entire length of the wire and cable. 3.5 Durability and anti-expansion of markings
The markings should be clear and resistant to wiping. The markings should remain unchanged after being rubbed. When cleaned with Sichuan Auto or other appropriate agents, the marking color should remain unchanged
When the machine is sprayed, repaired or maintained, the markings of wires and cables should be protected according to GB8502 to protect the clarity and integrity of the markings. 4
Circuit and functional group
Wires and cables can be marked in the identification mark to indicate the circuit or functional group they belong to. Circuits or functional groups and wires and cables can be marked according to the following table. Electrical devices for marking

4.3 The marking and identification of wires and cables shall be coordinated with the electrical circuit diagram of the machine. The marking and identification of wires and cables and their corresponding connections, the nominal cross-section of the conductors of wires and cables (the nominal cross-section of small conductors in complex circuit diagrams can be listed separately), the voltage and grounding polarity of the line shall be shown in the electrical circuit diagram. The graphic symbols and drawings of electrical components are shown in GB4728. Additional remarks:
This standard was proposed and formulated by Tianjin Engineering Machinery Research Institute of the Ministry of Machinery and Electronics Industry. This standard was drafted by Tianjin Engineering Machinery Research Institute of the Ministry of Machinery and Electronics Industry. The main drafter of this standard is Ling Runcai.
