In home renovation construction, almost all wires are put in PVC pipes and buried in the walls. In general, single-core 1.5 square wire for lighting, single core 2.5 square wire, for socket, single core 4 square wire for 3 air conditioners above, single core 6 square wire for total Line, two-color line for grounding. Air conditioning line is now a new house is good, under normal circumstances do not increase the air conditioning line.
In addition, Yuba's wires also use the outlet line, which is 2.5 square, with 4 square is the most ideal effect. Today's PVC pipe generally has two points and four points. Use 6 points if conditions permit, and indicate in the budget. A 4-point tube can only wear 1.5 light lines, and a tube can only wear up to 3 wires. 6 points of the pipe can wear 2.5 wires, and a maximum of only 2.5 wires can be worn in a tube.
There are two main reasons why wires run through PVC pipes: one is because of protection and insulation, and the other is to ensure future maintenance. When using PVC pipes, use connectors at the time of docking and use glue to secure them. In addition, the connection between the PVC pipe and the wire box must use a dedicated cover, do not directly use PVC pipe and wire box docking.
1, wiring basics
Pipeline wiring is the basis for cloth "live lines", laying the foundation for future line maintenance, replacement, and household intelligence.
2, protective insulation
Prevent damage to the insulation of the wire. If buried directly in the cement mortar, the silicate may erode the insulating layer of the wire, causing the insulation of the wire to drop and causing a short circuit;
3, to prevent fire
In case of electric short-circuit causing the wire insulation to ignite, the line tube can play a role in preventing the flame from spreading, because the line tube is made of flame-retardant material and does not burn itself, which is usually called “flame-retardant tubeâ€. If you don't use a wire tube, there are other wires or flammable materials next to the wire that are dangerous.
4, heat dissipation
Because the cross-sectional area of ​​the wire is determined by the load, there is usually a margin for wiring, but it is still possible to alleviate the wire heating caused by special conditions.
During the renovation process, many owners and decoration companies attach great importance to the construction quality and effect of “carpentry work†and “brick workâ€. They do not know that the greatest impact on future use is neither the unevenness of the brick shop on the ground nor the Whether the paint brush on the wall is firm, but whether the laying of indoor wires, telephone lines, and cable TV cables is safe and reasonable.
