Does anyone know what these two lines are?

Thank you. It's a discolored thread, so there's no wire number.

Thank you very much for the link, it's very useful.

Summary. Hello, please wait, I'm texting, please wait a moment.

What a line this is.

Hello, please wait, I'm texting, please wait a moment.

It is a white grid line, also known as a dredging island.

The function is to make the merging lane and the main lane have a safe distance to ensure traffic safety.

This is the TOP C fast charging cable.

Most chargers nowadays are stupid like this.

For Android machines, grinding is like this at both ends.

This is the middle live wire end of the dual-control switch, and L11 and L12 are the control end of the switch.

KVV control cable is a kind of cable. It is used for power cables. It is used for AC rated voltage 450V, 750V and below control monitoring loops and protection circuits.

Among them, the shielded control cable, due to its good shielding performance, has been widely used in power plants and power stations, and the cable is laid in indoors, cable trenches, pipelines, direct burials, shafts and other fixed occasions that can withstand greater mechanical tension.

The color of the core is to facilitate the matching and selection of lines at both ends.

Pigtail, also known as pig tail wire, only one end has a connector, and the other end is a broken end of an optical cable core, which is connected to other optical cable cores through welding, and often appears in the optical fiber terminal box, which is used to connect the optical cable and the optical fiber transceiver (couplers, jumpers, etc. are also used in between).

Fiber optic network cable is this.

It's wires, right? It could also be a network cable.

Fiber optic cable, the kind with interfaces.

Zhou should be a wire, right? It could also be a network cable.

Charging cable, or some kind of electrical appliance.

The network cable interface is connected to the modem.

This is the data cable that connects to the wifi.

This one could be the kind of miscellaneous cable behind the TV.

This is an ordinary fiber optic cable, there is no electricity on it, and the wire cannot be bent or it will be broken.

It's silk thread because it has white silk.

This is the most common fiber plug for network cables, at home.

Broadband, connected out, fixed fiber interface, that interface plugged into the cat.

Fiber optic cables. The optical fiber cable is made of multi-core optical fiber inner core, special micro convex lens technology, so that the beam is highly focused, greatly reducing the reflection of the beam on the inner wall of the optical fiber, thereby shortening the transmission stroke, the beam can reduce the transmission time difference after focusing, effectively reduce the digital time difference distortion, is the most reliable digital transmission medium, widely used in CD *** dat md ld and other digital equipment, is the best guarantee of high-definition audio reproduction.

Fiber optic cables. There should be a wire in it, as well as a glass wire.

Optical fiber connectors, the most common optical fiber plugs, are all like this in the optical modem at home.

L phase (live wire), n middle line (neutral line).

Phase wire: In order to make the alternating current have a very convenient power conversion function, usually three-phase sinusoidal alternating current is used for industrial electricity, and the current phase (reflecting the direction of the current) is 120 degrees different from each other. Usually we refer to each of these wires as phase wires (live wires).

Neutral line: The neutral line is the line drawn from the neutral point (n) on the secondary side of the transformer, which forms a loop with the phase wire (L) to supply power to the electrical equipment. Under normal circumstances, the neutral line is repeatedly grounded (PEN) with the protective ground wire (PE) at the neutral point (N) on the secondary side of the transformer, which plays a double protection role.

Note: In the single-phase transmission line entering the user, there are two lines, one we call the phase line L, and the other is called the center line N, the middle line normally needs to pass the current to form the circuit of the current in the single-phase line. In the three-phase system, when the three-phase is balanced, the neutral wire (neutral line) is current-free, so it is called the three-phase four-wire system.
