When the wire is made, it needs a layer of foil inside, and the outside is insulated. Why is that?
There is an insulating plastic outside the wire and the joint will surely expose the wire. To be safe, wrap the black tape and explain the amount of acid and base in the]1. to interact with each other to produce salt and water. The resulting substance loses the properties of acids and bases. This reaction is characteristic of all acids and bases.2. neutralize.3. with the toxin antitoxin or antivenom effect, produce other substances, so that the toxin toxicity disappeared.4., the body of the positive and negative electricity equal to the phenomenon of non charged phenomenon called neutralization.
See what the wire is used, generally used as signal wire wire, aluminum foil is shielding effect, used to reduce the external irrelevant signal to transmission signal interference, if only conductive use, no need to use foil.The insulation doesn't need to be explained
Wire, usually used as a signal wire, is used as a shield to reduce interference from external signals to the transmitted signal;Insulation is done outside to protect or leak electricity.Cable foil is the use of aluminum foil sealing and shielding, single or double coated plastic film, an aluminum foil plastic composite #, used as a shield cable. The cable foil requires less oil on the surface and has no holes. It has high mechanical properties, but the overall quality requirements are not high, but the requirements of the length are very strict.
The wire and wire of the signal wire are shielded and electrically conductive.
Aluminum foil can increase the conductivity of the conductor and slow down the ampacity of the conductor itself
