Design the whole intelligent home cabling system, need the total control switch. The Internet age and the information age of the product of rapid change, a family several phones or multiple devices on the Internet, it was very common at that time. In order to ensure the docking quality of various weak electric cables for the later maintenance management, the home telephone system and network cable design a centralized control unit to control the entire home intelligent network.

During the laying process, we can select a small wire box(shaped like a power cable box) according to the location of the network line entry room, such as the hall, aisle, and above the study. All external incoming voice lines, network lines, and cable television lines are reached in this line box. At the same time, the lines of telephone jack, network Jack, and cable Jack in each room in the home must also reach this line box, depending on the family. Need to connect in the online box. In order to ensure signal quality, a multi-branch adapter for television signals needs to be added to the online box. If there are multiple computers in the home to access the Internet, a network hub is also required.

Weak electric cables should be distinguished from strong electric cables. The weak electric information belongs to the low-voltage electric signal, and the anti-interference performance is relatively poor. Therefore, the weak electric cable ground direction should avoid the strong wire(that is, the power cord used by the family). According to the relevant national regulations, power cord and socket, television cable and socket should not be less than 50 cm horizontal distance.

Weak electric cables and their supporting equipment need to be mainly damp-proof. The underside of the socket is suitable for about 30 cm from the ground. Because these weak electric cables are often wired on the roof or under the floor, these cables need to be fitted with strong casings outside to prevent moisture and replace them. And check the line for short circuit before adding the casing.

Quality practices:
Specification for cable binding, complete set of circuit identification

Pipeline installation of shaft equipment

Frequently Asked Questions:
There are joints in the bridge frame, local bare lines, irregular connection of the pipe into the bridge frame, and metal hose connection in the floor, and the bridge frame can not be sealed.

The color separation of the wire: When the wiring uses a multiphase wire, the phase line should be colored. The protective ground line(PE line) should be yellow and green, and the zero line should be light blue; Phase line use: A phase-yellow, B phase-green, C phase-red.
Wire connection:
When using tin welding method to connect the copper core wire, the solder should be full and the solder is not corrosive. The waterproof and insulated two layers of adhesive tape wrap evenly and tightly.
When using a safety type copper wire pressure wire cap to connect a copper core wire, the quality of the pressure wire cap should be sampled and the oxygen index must be & GT; 27 <UNK>.
Electric power, lighting, automatic control and other lines in Super high-rise buildings should use flame retardant wires or cables; Evacuation lighting lines should be made of fire-resistant wires and cables, which should be applied clearly through the tube or through rigid ducts in the non-combustion body, and the thickness of the protective layer should not be less than 30mm.
Emergency lighting lines have a separate circuit in each fire protection zone, and lines passing through different fire prevention zones have fire protection barriers.
The connection of the core wire to the electrical equipment shall meet the following requirements:
Single copper core lines and single aluminum core lines with a cross-sectional area of 10mm2 or less are directly connected to the terminals of equipment and appliances;
Multiple copper core lines with a cross-sectional area of 2.5 MM2 and below are connected to the terminals of the equipment and apparatus after tightening the enamel or connecting terminals;
Multiple copper core lines with a cross-sectional area greater than 2.5 MM2 are connected to the terminal of the device or appliance after the connecting terminal except for the device's own insertion type; Before the multi-strand copper core line is connected with the plug type terminal, the end part is screwed tight.
The multi-strand aluminum core line is connected to the terminals of the equipment and apparatus after the terminals are connected.
The in-pipe wire piercing works should be carried out after the dust and ground works of the building are completed. All kinds of boxes must be installed in place. It is forbidden to penetrate the wire and box boxes.
The cable in the cable bridge frame should be marked with the cable trunk number, model and purpose at the head, tail, turn and every 50m.
Cable can be applied in the online slot, but should not be directly laid in the bridge or tray. (GB50168-2006).
The wires laid in the grooves should be tied into bundles according to the loop, and the fixed spacing ≤ 2M. The wires must not be connected in the grooves. The grooves installed in any place must have complete cover plates.
