How to install the wires for villa decoration?

Because the villa is relatively large, the service life of the cable is usually the best within 20 years, so if the following conditions are met, there are likely to be problems such as wire fire and short circuit. The three aspects that should be considered most are: conductor throughput (conductor square), connection mode and loose connector.

1, wire side: In villa decoration, the most commonly used wire specifications are 1.5mm2, 2.5mm2 and 4mm2 copper core wires. For high-power electrical appliances at home, such as sockets for air conditioners and water heaters, it is enough to use 4mm2 wires. If you use 6 square meters of wire, it will be safer, but it will also increase the difficulty of construction.

2. Wiring method: In the past, black tape may be used to solve the wiring problem, which is very easy to age and very unsafe. At present, the connector directly replaces this traditional binding connection mode, which has the characteristics of insulation, fire prevention, faster installation, low installation cost, firmness and fast current test. Connect the cables one by one directly with connectors, and then embed the grounding wire, live wire and zero wire, and the power socket will fully play its role, with fast working hours and no safety concerns.

3. Connector: The selection level of connector includes three-hole toggle connector, two-hole or four-hole connector, spring screw grounding cap and other types, depending on the use requirements. The other one has a waterproof wiring cap, and the waterproof sealant in it allows the cable to be inserted without fear of short circuit, which is usually used in gardening and outdoors. It can effectively avoid the fire hazard caused by the aging and leakage of the line caused by the winding of the black tape wiring. When the circuit is burnt out due to excessive current, it can be immediately flame retardant and maintain good clamping force.

Common problems in installation of household wires in villas

1. Bad cable winding: The traditional construction technology is to tie the cable with cable tape, which requires six turns, and then connect it to the power socket. If the winding is not good, it is very easy to cause cable short circuit fault and fire accident.

2. Excessive current and voltage load: summer is the peak of electricity consumption. If the electricity consumption of home decoration is too large and the load is too heavy, it will form high heat, which will make the cable unbearable and start to burn.

3. Looseness: The traditional tape binding is to facilitate current connection and give full play to the role of insulation. However, if the winding is not firm, it is very easy to loose, and the formed heat will embrittle the cable belt, so it is easy to loose the winding and cause short circuit.

It must be noted that the price difference of a line with the same specification is 20%-30% because of different manufacturers. This is caused by different raw materials of wires. The main raw materials of wires are electrolytic copper, insulating materials and sheath materials. The tricky price difference is the difference between wires made of real materials and wires processed from recycled waste.
