How many square wires are used for home wires? It is best to have a detailed answer
Socket with 4mm ^ 2 copper wire, lighting with 2.5mm ^ 2 copper wire.
The problem is two questions . first explain why the wire cut inside why there are many things like gray, because the insulated wire core is PVC insulation, in the course of aging, the inside of the agent decomposition, or inside the filling In the use of a long time after the brittle aging will become dust, that is, the inside of the wire is actually due to the aging of the internal material. . the copper wire is very brittle, the first copper rod in the production of copper is very brittle when the strength is high, but the toughness is poor, the need for annealing to make copper wire becomes toughness becomes low, easy to pull and mass production, if the landlord Think this copper wire is very easy to break, you may not be in line with the national standard of the wire or the production process is not in place for annealing, for reference only.
ZR: flame retardant K: control cable code VV: recording ethylene insulation and sheath R: soft structure conductor (multi-strand wire) P: copper wire braid shield 1: 1 to 2 * 1.5: two 1.5 square single Twisted pair Full name is: flame retardant type recording ethylene insulated and sheathed copper wire braided shielded flexible cable. If it is 10 pairs of 2 by 1.5 square control cable, that is 10 * 2 * 1.5. In addition, the control cable, the conductor is the largest square: 4 square.
This question when the two questions . first explain why the wire cut inside why there are many things like gray, because the insulated wire core is PVC insulation, in the course of aging, inside the assistant decomposition, or inside the filling In the use of a long time will become brittle aging into dust, that is, the wire inside the gray is actually due to the aging of the internal material . the copper is very brittle, first copper rod in the production of copper is very brittle High strength, but the toughness is poor, the need for annealing to make copper wire becomes toughness strength becomes low, easy to pull and mass production, if the landlord think this copper wire is very easy to break, you may not be in line with the national standard Or the production process is not in place for annealing, for reference only
