China is, or used to be (the current material may be some made made material) china on power lines. The separators were made of china to insulate them.
Disconnect the device. Open your steering column and find the wire harness that goes to the device. You'll see that your ignition wire is cut, and runs to two wires in the harness. Cut those two wires from the harness, splice them back together, and you'll have effectively re-connected your ignition wire.
It is an outlet that has one hot wire, such as a household receptacle, or two hot wires, such as a dryer outlet (in the US). If the outlet has three hot wires, it would be called a 3-phase or polyphase outlet. These would normally be found only in an industrial setting.
some simple machines do need wires and some dont
Single phase requires 2 wires - a hot, and a return (both wires of the same size. Three phase requires three (same size), and if it is grounded will require a forth (doesn't normally carry current so it can be small). Two phase requires three wires (two phase conductors of one size, and a return that can handle double the current of the phase conductors), or four wires (same size for all, effectively two separate single phase supplies). It isn't economical is the bottom line. It costs ~the same (in wire) for two phase as three, and you get 50% more power delivering capability with three phase.

To cover exposed electrical wires safely and effectively, you can use electrical tape or wire nuts to insulate and secure the wires. Make sure to turn off the power before handling the wires and consult a professional if you are unsure about how to properly cover them.
What is the name of our distinguished animal put on the wires of the telegraph?
wires
To insulate the wires
To connect electrical wires safely and effectively, first ensure the power is off. Strip the insulation, twist the wires together, and secure with a wire nut or solder. Insulate the connection with electrical tape or heat shrink tubing. Finally, test the connection before restoring power.
To effectively twist wires together for a secure connection, follow these steps: Strip the insulation off the ends of the wires. Hold the stripped ends of the wires together. Twist the wires together tightly in a clockwise direction. Use pliers to further twist and secure the connection. Insulate the connection with electrical tape or heat shrink tubing for added protection.
There were telegraph wires before Titanic sunk. Samuel Morse developed the system in the 1830's but we didn't have the WIRELESS telegraph until Guglielmo Marconi, much later on.
because telegraph wires were poles along the railroad tracks
The telegraph first came into existence around 1832. Simple and general components of a telegraph include an acid tube, hydrogen bubbles, and wires.
The difference is the telegraph required wires; the radio did not. But other then that, they were mostly the same.
By 1860 the Midwest and the West were united by a network of telegraph wires. The network of telegraph wires played a big role in the Civil War.
