Auxiliary materials and system integration
National standard

Wire specification:

The power line adopts the national standard of three-core anaerobic copper wire RVV3*1.0;
The signal line of VGA line adopts professional tin-plated signal line VGA signal extension cord (3*6 lines);

3.RVV2*0.3 is adopted for the control line of the projector and the central control line;
4. The network cable adopts standard UTP*5 and standard crystal head.
The wire groove is protected by *9**9PVC wire groove and fixed with #8 expansion tubes and expansion screws. All the above wires: meet the national standard, meet the transmission requirements, power sockets meet the national standard, meet the connection requirements; Metal or plastic wire groove and buckle, in line with national safety standards, all lines are protected by steel or PVC wire groove as required;
Remove dirt and water in the groove before wiring: (waterproof; should lay electro-insulating rubber for anti-creeping on the surface of area where people pass often).
Before laying the cable, check the model, specification, program, route and position in accordance with the design requirements.

The total cross-sectional area of conductors, including insulation, in the same groove shall not exceed *0% of the internal cross-sectional area; Cable placement should be flat, do not produce twisting, winding and other phenomena, should not be subjected to external force extrusion and damage;

The cable shall be labeled at both ends before laying to indicate the starting and ending positions, and the label shall be clearly, uprightly and correctly written;
Power cables, signal cables, audio-visual cables and cables of other weak current systems in the building shall be distributed separately. There should be redundancy when laying cables. The reserved length of the cable is 0.3 to 0.6 meters; If there are special requirements, the length shall be reserved according to the design requirements; The network wire and the power line are separated at least 5 cm above each other to prevent electromagnetic interference. The traction force of laying the cable shall be less than *0% of the allowable tension of the cable. The cable in the groove shall be straight, not crossed as far as possible, and the cable shall not overflow out of the groove. The cable shall be tied and fixed at the corner of the groove.

In addition, the connection between the power line and the power plug board, the inlet and outlet lines of the stabilized voltage power supply and the air switch should be firmly connected in accordance with the standard to ensure that there is no heating, poor connection and other faults. The power line in the machine room must be reliably grounded. Install surge arrester with module type power supply in the distribution box of the professional classroom, the equipment conforms to Computer information system lightning protectorï¼ˆCA*******8ï¼‰, the design of the integrated wiring system shall conform to GB/T *********7 Code for engineering design of integrated wiring systems for buildings and building complex. Acceptance of general wiring system engineering shall conform to GB/T *********7 Code for acceptance of building and building complex cabling system engineering. Specific system integration can be seen in the construction scheme
