What are the precautions for circuit wiring in shopping malls?

The layout of the circuit in the circuit wiring diagram of the mall decoration is very important, so what are the requirements for the wiring design of the mall? What should I pay attention to? Let me introduce it to you. So, what are the wiring design requirements of shopping malls? The layout should be reasonable, and the crossing lines should be reduced as much as possible, which is easy to cause cable short circuit, but the crossing lines must be met, and the energy should be less. Let's take a closer look at the wiring design of the mall! Design requirements of integrated wiring in shopping malls

1. The design follows the principle of "overall planning, decentralized implementation, and horizontal wiring in place as far as possible".

2. The wiring adopts unshielded twisted pair or mixed wiring of twisted pair and optical fiber. Materials shall be supplied by a manufacturer for construction, and network testing and networking shall be done well before opening.

3. According to the comprehensive wiring capacity, design a large number of cables and optical cables (provided by telecom operators free of charge). The products provided by telecom operators should be strictly controlled to avoid unstable system operation in daily operation.

4. Optical fiber is used in the trunk data part over 90 meters, and five types of eight-core wires are used within 90 meters. Three kinds of 50 pairs of large logarithmic cables are used in the trunk voice line (the number depends on the actual situation), and all the horizontal parts are over five pairs of twisted pairs.

5. The distance between the terminal information point and the floor distribution frame should not exceed100m. When setting the location of wiring closets, it should be considered comprehensively: when the single-story span is too large, more than two wiring closets can be set on one floor, and when the single-story span is not large, one wiring closets can be used on two or more floors.

6. Five types of eight-core cables cannot be used for telephone and computer access at the same time.

7. Strong current shaft and weak current shaft should be set separately, and lighting and strong current wall sockets should be set in weak current shaft.

8. According to the nature of shopping malls, the basic wiring system is generally used to design the distribution density of information points, that is, one information point in each column (single information socket) or a pair of information points in every other column (double information socket).

9. Supermarkets, fresh, dried fruits, bulk cargo areas, men's and cosmetics shopping malls, women's shopping malls and other places with frequent brand changes should increase the density of information points, and design according to the enhanced wiring system to ensure that each column has at least two information sockets.

10, two pairs of information points (four five-category eight-core lines) in each column in the supermarket exit counter area.

1 1. The financial office should evenly distribute a pair of information points every 1.5m on the wall around the office.

12. In order to ensure the normal use of communication tools by customers, contact the communication department in time as needed, and set up a mobile phone signal amplifier and a PHS hub. The construction unit shall submit information point test data after installation acceptance.

Matters needing attention in circuit wiring of shopping malls

1, the lines should be horizontal and vertical.

In the crowded environment, it is very important to ensure that the lines are horizontal and vertical, because circuit failures or inconveniences will inevitably occur in the later period, and horizontal and vertical lines have become the standard in the current construction standards. We can't pull the cable in a hurry to save trouble. When decorating, we must design the groove and pipe of the line in advance to avoid the situation of the line straggling.

2. Strong and weak wires should be separated.

In the wiring diagram of shopping mall decoration circuit, the capacitance used by each store and equipment may be different, so we need to separate some current from some strong electricity. At the same time, we must ensure the separation of strong and weak cables, so that when there is a fault in the later stage, it is easy to find and repair the cable, and avoid the influence of the weak cable or the strong cable on the other cable.

Step 3 take the wire on the wall

In some catering activities, these wires and circuits need to pass through the wall instead of the ground, because there may be some water or some wet things spilled on the ground during some catering activities. If all wires are laid on the ground, it will lead to conduction or decay, which will lead to life safety hazards. Moreover, in places like bathrooms and kitchens, the walls and floors are very decorative, and some tiles are not conducive to our later maintenance and replacement of wires.

4. Comprehensive design

We should specifically consider the layout design of the decoration circuit of the shopping mall according to the electricity consumption of all aspects of the shopping mall and the electricity consumption of equipment, which can facilitate the later electricity consumption of merchants and shopping malls, leave more space when connecting wires and laying wires, prepare for the future development of the shopping mall, avoid the scattered distribution of some socket wires in the later period, save time and financial resources and ensure people's safety.
