W22 in the cable on behalf of what
Not W, is VVVV22 means the meaning of plastic insulated plastic sheath with armored copper cable. Wire and cable: wire and cable is the transmission of electrical energy, electrical signals and electromagnetic energy conversion to the wire products. Cables are usually made up of cable cores that transmit electrical or electrical signals and protective, insulated sheaths. A cable with only one cable core and a smaller diameter is often referred to as a wire. Also some wires do not have insulated sheaths, called bare wires. The cable in the cable is made of a metal material with good electrical conductivity, usually copper (good electrical conductivity) or aluminum (lower cost).
Oh, not W it should be VVVV22 is the meaning of plastic insulated plastic sheath with armored copper cable
Is the name of the vv22 it is armored copper core PVC insulated power cable V is PVC, VV said PVC insulated PVC sheathed, insulation and sheath is two different things, the jacket is the outermost layer of the cable, Insulation, mainly from the role of protection cable, the insulation layer is wrapped in the conductor outside the layer, mainly from the insulation. 22 means armored, armored between the sheath layer and the insulation between the strip, and its role is to strengthen the protection of the cable, at the same time, can prevent the mouse bite, can also be used as ground. The copper core is not shown in the letter in the model, because most cables are copper, so the copper cable basically takes its representation (indicated by T). On the contrary, if it is aluminum core cable, it will be added in the model L said aluminum core.
