Specifications and specifications of indoor wire and cable
A. does the wire conform to the quality approval of the national Electrotechnical Commission?. (or have "CCC" certification)B. to see whether the line meets the requirements of power consumption quota, product inspection certificate, product quality special logo.C. look at the purity of copper, the higher the purity, the better the quality.D. look at the quality of copper core PVC material, the better the quality, the lower the probability of leakage.E. look at the length and weight of each reel of wire, and use the temperature from -30 to 70 degrees celsius.
Commonly used wire cross-section specifications are 1.5mm, 2.5mm, 4mm, 6mm, 10mm. 1mm wires can withstand up to 5-6 amps of current.
Hard wired (BV): for power supply, lighting, outlet, air conditioningFlexible cord (BVR): for power supply, lighting, sockets, air conditioningHard and flexible cord (weak wire): each consists of single and several copper cores
Plastic copper wire: usually with threading pipe used together, mostly used in building decoration works hidden works. The ground between different lines of zero, fire, design, surface of different colors, and more generally to the red line represents "FireWire, double color line represents the" ground ", the blue line represents the zero line, but because the construction requirements of different occasions and different conditions, the color distinction is not the same.Cable: a double insulation sheath wire, it can be used for the construction on the wall outside the dew line, due to its double sheath, make its insulation and anti damage performance is greatly improved, but the relative thermal performance of plastic copper decreases, so does not advocate multiple sheath wire tied together; it will greatly reduce the cooling ability, a long time will make the wire aging damage.
The wiring is determined by the function of each room.Living room: lighting, there are air conditioning, television, audio and so on, wiring power to consider a little larger, more than 2.5 square meters, broadband Internet line can also be embedded good. It is better to have three eyes and two sockets for each wall.Study: computer, telephone line is necessary, because the electronic equipment inside the study, so the socket to some more in the near future, you may also add equipment.Bedroom: phone and lighting line is necessary, if the bedroom has some special equipment, such as small audio, massage chairs, etc., you should arrange a larger power outlet.Kitchen: now more and more electrical appliances in the kitchen, microwave ovens, dishwashers, coffee machines, ovens, juicer and so on, so more wiring. Most of the kitchen equipment needs grounding, and the arrangement of sockets should be easy to use, such as mounted on the countertop.Toilet: lighting line and telephone line socket, the general layout of the mirror near to some Dobb with protective door socket, such as massage bath to increase the power socket.Balcony: lighting and socket line. If you want to keep tropical fish on the balcony or put in a fitness device, you need to keep enough sockets.
