How To Make The Decoration More Convenient When The Wire Material Is Selected Well!

Many people have encountered troubles such as frequent short-circuits in the light lines at home, and plugs in the house. If they want to improve the quality of life, the materials for the decoration of the wires in the early stage must be well taken care of. Worried that the materials selected by the decoration company are not good enough? Choose by yourself! Wait, have you done your homework? What big materials and small accessories are needed for home improvement circuits? What type of wires do you need to buy? How to choose the brand, imported or domestic? to say.

What materials should I buy when my electrical wiring renovation is about to start?

Waterway: water pipes and fittings

1. Circuits: tubes, wires, boxes, switches, sockets, accessories, etc.

2. There are many circuit materials, and the materials required for early wiring include:

3. Wires: single-core wires, multi-core wires, twisted-pair wires, fancy wires, network cables, telephone wires, audio-visual wires, and network crystal heads.

4. Accessories: wire conduit, tee, cassette, elbow spring, box connector lock, direct connector, waterproof insulation tape, broadband network TV 1:2 TV junction box, circuit breaker, horizontal pipe.

Materials to be installed later include:

Switch: single open/double control, double open/double control, single billing control, double open/single control, double open/single control, triple billing control.

Socket: socket (two or three holes), socket (three holes) (10A), air conditioner socket (16A), single/double connection 500Hz video socket, computer/telephone/audio socket, whiteboard.

What are the main materials used in circuit construction?

In fact, there are only two most important materials in circuit construction, PVC pipe and wire.

1. PVC wire pipe is a plastic pipe used to protect wires during the wiring process. It is mainly made of hard PVC flame-retardant pipe, which is convenient for threading and wiring, and safe.

2. Generally, there are three types of household wires: 1.5 mm, 2.5 mm, and 4 mm (there are also 6 mm and 10 mm wires, but they are mainly used as the main line for entering the house, and are generally not used for circuit construction), and 1.5 mm wires are mainly used for lamps, The lighting of the switch; the 2.5mm wire is mainly used for socket power supply and common ordinary electrical appliances. The 4mm line is mainly used for the main line of the circuit, air conditioner, kitchen, etc.

3. In addition, there are two types of wires, one is single-core (BV wire), and there is only one wire in a layer of insulation. The other is multi-core (BVR wire), which has multiple conductors in one insulation layer. number

4. Single-core wires and multi-core wires can almost be used in the construction of home improvement circuits, but they have different uses and each has its own advantages and disadvantages.

5. The single-core wire is generally hard, with a small cross-sectional area, not easy to overheat and oxidize, and has a long service life. It is generally used for fixing on the ground in the threading pipe, and is mostly used for strong wires.

6. Multi-core wires are generally composed of multiple copper wires, with soft hardness and complicated process. They are suitable for turning and threading of pipes, and are mostly used for signal transmission and connection of electrical appliances such as network wires and TV signal wires.

The connection method of the wire, the connection method of the single core wire:

Cross the two ends of the two conductor cores, twist each other 2-3 turns, then straighten the ends, then fit each end tightly to the other core and wrap 6 turns, then cut off the excess and clamp flat. As shown in the picture. Finally secure it with insulating tape.

multi-line parallel method

Wrap multiple wires tightly around the center line, and finally bend the end of the center line to fit other lines; there is a simpler method, as shown in the figure.

How to choose household wire?

1. There are many brands of wires; almost every region has its own brand of wires, but there are also some old and famous XSD Cable brands in China. There are also some popular imported brands, such as Prysmian (also known as Pirelli), which is not only famous for tires, but also for excellent wires, which have been recognized by BASEC, the British cable certification unit. France ranks among the top three in the world; Japan's Furukawa was established in 2005, and is good at researching wire technology; the highly acclaimed joint venture Delixi, etc.

2. I don't know what kind of wire is good. When choosing a wire, please refer to the following standards:

Find the national standard wire. Generally, there are obvious signs on the outer packaging and wires.

Possess China National Compulsory Product Certification CCC, production license number and quality system certification;

Check the packaging and marking: there is a complete certificate in the package, and the certificate should include complete information such as specifications, implementation scale, rated voltage, length, date, factory name and address.

Look at the production process: cut a section of insulated copper wire to see if the core wire is in the middle of the insulation layer, and whether the thickness of the front and rear insulation layers is uniform. It is also possible to repeatedly bend the wire. A good wire feels soft, has high elasticity, and has no cracks on the insulator.

Check the quality of the copper core: the high-quality copper core is purple, shiny and soft; the poor-quality copper core is yellow, white or black, with more impurities.

Check the size of the wire: the length of a circle of wire is generally about 100 meters, not too little; measure the cross-sectional area of the inner core to see if it meets the specification.
