Cable what skin color SXXLJT P everyone know all kinds of cable products inside a few wires have different color, the color is what?
Below is copper bridge electric co. , LTD. Small make up to you to introduce the network cable what color is representative of the above.
Black: internal wiring devices and equipment.
Brown: the positive dc.
Red: the three-phase circuit and phase C;
The collector of a semiconductor triode;
A semiconductor diode, rectifier diode or silicon controlled rectifier tube cathode.
Yellow: the three-phase circuit of A phase;
Semiconductor triode base;
Silicon controlled rectifier pipe and the bidirectional thyristor control.
Green: the three-phase circuit of phase B.
Blue: dc negative;
Semiconductor triode emitter;
A semiconductor diode, rectifier diode or silicon controlled rectifier tube anode.
Light blue: the zero line of the three-phase system or the neutral line;
Dc earthed neutral.
White: the main electrode of the bidirectional thyristor tube;
No specified coloring semiconductor circuit.
Yellow and green double color (
Each color ~ mm wide alternant attached)
Safe with ground wire.
Parallel: red, black with double conductor or double stranded wire connection of ac circuits.
Ac three-phase circuit of A phase: yellow;
Zero line or neutral line, light blue;
Safety with grounding line: yellow and green double color.
With double conductor or double stranded wire connection circuit of communication: red and black in parallel.
The positive dc: brown;
Earthed neutral: light blue.
The collector of a semiconductor circuit of semiconductor triode: red;
Semiconductor diode rectifier diode and anode: blue;
Silicon controlled rectifier tube anode: blue;
Control cabinet: yellow;
Control of bidirectional thyristor tube pole: yellow;
The main electrode: white.
The whole internal wiring devices and equipment general recommendation: black;
Semiconductor circuit: white;
When there is confusion: choose tolerance specified coloring outside the other color (
Such as: orange, purple, grey, green, blue, rose, etc. )
Specific standard colors, on a wire, in case there are two or more color, depending on the specific situation of the circuit, in accordance with the circuit you need to represent a certain meaning of color.
