School engineering construction integrated wiring integrated construction plan

1. Preparation in advance [Responsible by the school, the funds will be settled by the county or school]

1. The electrostatic floor or cement floor is laid.

2, the power supply to the classroom: the electrical box is open, the computer room three-phase four-wire power supply, 40a per phase, there is a grounding wire. Computer room broadband or adsl access line to the podium, air conditioning. The multimedia classroom podium and the TV cabinet are connected to two single-phase power sockets.

3. Supporting facilities are in place: 50 sets of student desks and chairs in computer classrooms, teacher's podium, multi-functional podium of small and medium-sized multimedia classrooms in rural middle schools and township centers, and 34-inch digital TV cabinets are all neatly arranged.

4. Supporting construction materials are in place: 27 outlets for power sockets: four-way three-hole, 3c certification, one-way main switch or four-way switch. AC power cord bvr 4 square national standard line.

5. Construction management personnel, information technology teachers, and electricians are in place: The school designates a school principal to be responsible for the management, guidance and coordination of the entire construction process, and the information technology teachers participate in the whole process. Select towns with high qualifications to participate in the construction of strong electric wiring and receive the guidance of technical personnel of the construction team.

Second, construction preparation

1. The network cable exceeds five categories. [The person designated by the county is responsible for distribution, and the construction team will use it according to the plan credentials. ]

2, tape, cable tie, crystal head, self-tapping wire, pvc pipe, etc.

3, tool preparation: hole opener, electric drill, line gauge, crimping pliers, etc.

4. The special trunk line for strong and weak electricity is produced by the Municipal Education Bureau “General Office”, and the pvc pipe is prepared by the construction team.

Third, construction requirements

1. Power wiring construction: The selected electrician shall strictly follow the requirements under the guidance of the technical staff of the construction team. Each line under the static floor has three lines, fire, zero color, ground color, and the connector meets the electrical safety requirements. The cement floor classrooms are connected by special galvanized wire troughs at the walkways and podiums, and the wire trough casing is grounded. The student desk is protected by a pvc pipe connection. At the intersection of the underfloor power supply and the network cable, the power cable is isolated by a pvc bushing. The line is tied to the bracket with a tie so that the line is suspended. There is a margin for the length of the power outlet cable.

2, weak electricity construction: pc power supply, network cable outlet spacing is uniform, leaving a margin for the outlet. The network cable is consistent with the number of the number. The network cable at the switch is neatly arranged to leave a margin. The floor outlet of the platform is opened with a hole opener or the square hole is cut. The cement floor classrooms are connected by special galvanized wire troughs at the walkways and podiums, and the wire trough casing is grounded. The student desk is protected by a pvc pipe connection.

3, safety requirements: strong electricity, weak electricity can not share the line slot, power switch set leakage protection, electrical materials to prohibit counterfeit goods. The anti-theft facilities are complete, and schools with conditions can install monitoring equipment. The galvanized steel trough is fixed to the ground with a nylon expansion tube and can be directly contacted with the “School-school” office of the Municipal Education Bureau.
