The different colours of the power cord represent different meanings, so it is important to be clear when wiring, each colour has its own use, only reasonable wiring can be better used. Here we will introduce you to what the power cord colours represent and what the power cord classification is.
The focus of this article.:colours of the power cord
목차
What does the colour of the power cord represent?
1, generally speaking, the power cord colour each represents a different representative, generally speaking are made of three colours wire colour for yellow, 개요, red, 각기, ㅏ, 패키지 상자, C three phases, "이것은 AC가 진동하는 반복에서 시간이 지남에 따라 변하기 때문입니다. 위쪽 곡선은 양의 방향으로 흐르는 전류를 나타내고 아래쪽 곡선은 전류가 음의 방향으로 이동하는 교대 주기를 나타냅니다., like blue is a zero line, yellow and green between this is the grounding line, wiring yellow, 개요, red this is connected to the fire line, blue is connected to the zero line, yellow and green between the line received PE protection line or to the equipment shell (shell has been connected to the ground network).
Sometimes four lines of colour feel not very good to distinguish, then you can three cross-sections of the same for the fire line, cross-section is slightly smaller is part of the zero line.
2, when it comes to the transformer control circuit power supply, generally speaking is in 380V, received any two fire wire are possible; such as 220V, then as long as you connect a fire wire, a zero wire so that you can.
What is the classification of the power cord
1, bare wire
This wire is generally speaking is only the conductor, and no insulation layer of the product, this wire it is included in the copper, aluminum, USB 전원 전압 레벨 및 커넥터의 폭넓은 수용으로 인해 전원 전용 애플리케이션에서도 널리 사용됨. So that the layout of this product it is crowded transmission line with stranded wire, flexible wiring, type of line and profile.
2, winding line
This kind of wire it is winding situation in the magnetic field cutting magnetic lines feel breeding current, this is also through the current breeding magnetic field with the wire, this kind of wire is also known as electromagnetic wire, and this kind of wire its characteristics of enameled wire, wrapped wire, inorganic insulated wire, etc..colours of the power cord
3, power cable
This wire can be said to be in the power system in a backbone line, so it plays a big role, mainly is to transmit and distribute high-power electrical power cable products.
4, communication cable and communication fiber optic cable
Communication cable this is used to transmit telegrams, television, 라디오, data and other electrical information cable; communication cable is played by optical fiber as a light wave transmission medium, there is information transmission role.
5, electrical equipment with wire and cable
This wire it is still widely used, relatively speaking, is also more varieties of a, and in the layout of the time can also be used in conjunction with the characteristics of the equipment and the use of the conditions to determine the layout of the product, 성능.
The distinction between the three types of wire.
1, distinguished by colour: in the power cable yellow green red represent A-phase B-phase C-phase (three-phase fire wire) blue represents the zero wire, yellow and green double-coloured represents the earth wire.
2, distinguish with the electric pen: the fire line with the electric pen test neon tube will glow, while the zero line will not.
3, distinguish with a voltmeter: the voltage between different phase lines (즉. fire line) for the line voltage 380V, phase line (fire line) and zero line (or a good grounding body) between the voltage for the phase voltage 220V, zero line and a good grounding body voltage of 0V.
Summary: on the power cord colour each represents what and power cord what classification related content is introduced to this, the power cord in the wiring must be clear about its meaning, so as not to connect the wrong, but also to find out which line is to play what role, I hope the above introduction to help you
