How To Read The Codes For Electric Cable
In the electric circuit diagram, the type, size and color of electric wires are shown by symbols. This symbol is called a electric wire cord and it is useful for understanding the electric circuit diagram.
Example) AEX 0.85 L: It shows the blue cable with the electrical wire number 0.85 for heat resistant low voltage electric wire for automobiles. AEX
The type of electric wire is shown by a symbol. The types, symbols and materials of the wires are as shown in (Table 1).
(For AV and AVS, it can be distinguished by size (electrical wire number), so they are not shown on the electric circuit diagram)
0.85
The wire size are shown by the electrical wire number. The wire size and electrical wire number are as shown in (Table 2). L
The color of electric wire is shown by color code. Color codes are as shown in (Table 3).
Type, symbol and material
(Table
Low voltage electric wire for automobiles AV
Thin low voltage electric wire for automobiles (Type 1)
Thin low voltage electric wire for automobiles (Type 2)
AVS
Soft vinyl chloride-30 to +60
For high current wiring (electrical wire number 5 or more)
For general wiring (electrical wire number 3 or less)
Annealed copper wires for electrical purposes
CAVS
Heat resistant low voltage electric wire AEX
Heat resistant crosslinked polyethylene -50 to +110
For medium and small excavators (electrical wire number 1.25 or less)
For general wiring of extreme cold weather specification
For wiring for high ambient temperature
•The difference between AV and AVS is only the coating thickness and the coating outside diameter.
• CAVS uses a circular compression conductor for the conductor.
•CAVS is different from AV and AVS in conductor outside diameter and coating thickness.
•AEX is different from AV and AVS in coating material.

"F" for the electrical wire number shows flexible.
Color code table
(Table 3)
Remark
In the two color configuration, the first color shows the ground color of the wire and the second color shows the marking color. Example) GW shows that there is white which is marking color in green which is ground color.
