GB 6995.5—86
This standard applies to power cable insulation The identification marks of wire cores include oil-filled cables, non-drip oil-impregnated paper insulated cables, viscous oil-impregnated paper insulated cables, cross-linked vinyl insulated cables, polyfluoroethylene insulated cables, polyethylene insulated cables and rubber insulated cables. 2 Wire core identification
.1 The insulated core of power cable adopts two methods of numerical identification and color identification. 2.2 Oil-filled cables, non-drip oil-impregnated paper insulated cables, and sticky oil-impregnated paper insulated cables are identified by numbers. 2. Cross-linked polyethylene insulated cables, polyethylene insulated cables, polyfluoroethylene insulated cables and rubber insulated cables are identified by color. Numerical identification is allowed under special circumstances. 8 Numeric identification
.1 General requirements
3.1.1 The outer paper tape of the insulating layer of the insulated core should be printed with Arabic numerals. 3.1.2 Unless otherwise specified, the color of digital signs shall be white. 3.1. Number signs should be clear and legible. 3.2 Use of numerical signs
The insulated cores of multi-core cables should use different numerical signs and should comply with the following regulations: 2-core cable.

4-core cable. ·
.*-0,1,2,3
The numbers 1,2,3 are used for the main wire core , 0 is used for the neutral core. Note: The neutral core core with a nominal cross-section of 16mm is allowed to be unmarked and use its natural color. 3.3 The maximum distance between two adjacent complete digital signs on the insulated wire core is 25mm, and the minimum height of the digital signs is 4.5mm. 3.4 The colorants used in digital signs should not be easy to fade, and should be chemically neutral and have no harmful effects on the cable paper fibers. 4 Color identification
4.1 The insulated cores of multi-core cables should be marked with different colors and should comply with the following regulations. 2-core cable
