What size wire is used for the lights in the hotel banquet hall?

1, and most common lighting power cords are 1.5 square meters. Of course, the size of the power cord can also be determined according to the total power consumption to avoid waste.

2. The power cords commonly used in sockets are mostly 2.5 square copper core wires. If the power of electrical appliances is high, 4-6 square copper core wires can also be used, but the power socket should be 16A or special socket, or the air switch can be directly used to control the start and stop of electrical appliances.

1.5-2.5 square lines are mostly used for lighting lines, and flexible lines are mostly used for lamp holder lines.

1, wires can generally be divided into the following categories.

Plastic copper wire: generally used with threading pipe, mostly used in concealed works in architectural decoration construction. In order to distinguish the zero line, live line and ground line of different lines, different surface colors are designed. Generally, the red line represents the "live line", the double-color line represents the "ground line" and the blue line represents the "zero line". However, due to different construction occasions and conditions, the color distinction is not the same.

Sheath line: The open wire exposed outside the wall can be constructed with double-layer insulated sheathed wires. Because of the double-layer sheath, the insulation performance and breakage resistance are greatly improved, but the heat dissipation performance is lower than that of plastic copper wire, so it is not recommended to bind multiple sheath line together. That will greatly reduce its heat dissipation capacity, and it will cause damage to the wires for too long.

Rubber sheathed wire: rubber sheathed wire, also called waterline, as its name implies, is a kind of wire that can be immersed in water. Its outer layer is an industrial insulating rubber, which can play a good role in insulation and waterproof. It can be said that the rubber sleeve is specially designed for outdoor use and construction, and its good anti-breakage performance and waterproof performance are widely used in many departments such as construction, industry, aerospace and navigation. 2, household wires can be divided into three types:

Hard wire (BV): used for power supply, lighting, socket and air conditioning.

Flexible cord (BVR): used for power supply, lighting, socket and air conditioning.

Hard wire and soft wire (weak wire): composed of single and multiple copper core wires respectively. 3. General dimensions of household wires. The cross-sectional specifications of household wires are 1 .5mm, 2.5mm, 4mm, 6mm and10mm, and1mm wires can withstand 5-6 amps at most.

4. Matters needing attention in wire procurement

A. See if the wire meets the product quality approval of the State Electrotechnical Commission. (or CCC certification)

B. See whether the wire meets the requirements of power consumption quota, product inspection certificate and product quality special mark.

C. look at the purity of copper. The higher the purity, the better the quality.

D. look at the quality of copper-core PVC materials. The better the quality, the lower the leakage probability.

E. See whether the length of each coil of wire is standard and the weight is sufficient, and the service temperature is -30 to 70 degrees Celsius.

5. The meaning of English letters of wires

R-wire multi-core BV copper-plastic wire ZR flame retardant V sheath (single core) BVVB sheath line YI rubber sheath

6. General rules for selection of household wires

(1) Lighting circuit generally adopts wire specification: 2.5mm.

(2) For general household appliances (such as household appliances, washing machines and other household appliances), the load line is 2.5mm..

(3) 4mm is generally used for special air-conditioning lines.

Note: If you buy BV line, please don't forget to buy PVC conduit protection line.
