Significance of Color Separation of BV Lines and Cable Lines
BV wire and cable color separation represents the meaning: wires and cable wires, various colors, various types of cable babies, can you distinguish according to the color? A brief introduction of the river cable;
1, black
Internal wiring of devices and equipment.
2, brown
The positive electrode of the DC circuit.
3, red
Three-phase circuit and C-phase;
The collector of semiconductor transistors;
A cathode for a semiconductor diode, rectifier diode, or a Silicon controllable tube.
4, yellow
Phase A of the three-phase circuit;
The base of a semiconductor transistor;
Control pole of controllable Silicon tube and bidirectional controllable Silicon tube.
5, green
Phase B of a three-phase circuit.
6, blue
The negative electrode of DC circuit;
Semiconductor transistor emitter;
An anode for a semiconductor diode, rectifier diode, or a Silicon controllable tube.
7, light blue
Zero or neutral lines of three-phase circuits;
Ground midline of DC circuit.
8, white
Main electrode of bidirectional Silicon controllable tube;
Semiconductor circuit with no specified color.
9, yellow and green two colors(each color width about 15 ~ 100 mm alternately)
Safety ground wire.
10, red, black parallel
An alternating current circuit connected by a double core wire or double twisted wire.
Select wire color according to circuit
1, AC three-phase circuit
Phase A: yellow;
Phase B: green;
C phase: red;
Zero or neutral line: light blue;
Safety ground wire: yellow and green. Recommended Products: Electric Cable
2, with double core wire or double root wire connection AC circuit:
Red and black parallel.
3, DC circuit:
Positive: brown;
Negative: blue;
Ground midline: light blue.
4, semiconductor transistor collector of semiconductor circuit: red; Base: yellow; Launch pole: blue.
The anode of the semiconductor diode and rectifier diode: blue;
Cathode: Red.
The anode of the controllable Silicon tube: blue;
Control pole: yellow;
Cathode: Red.
Control pole of bidirectional controllable Silicon tube: yellow;
Main electrode: White.
5, the internal wiring of the entire device and equipment is generally recommended: black; Semiconductor circuit: white; When confused: Allow the selection of other colors other than the specified color(such as: Orange, purple, gray, green blue, rose red, etc.).
6, when the specific color, on a wire, if there are two or more kinds of scalable color, depending on the specific situation of the circuit, according to the circuit needs to express a certain meaning to color
