Machine room length 7.6m, width 5.3m, about 40 square meters, the existing grounding copper belt 100m, specifications 3X30MM, insulated helium for the reclamation of the old rush to protect the child 10cm / sets, 100 sets, tin plating busbar 8 * 100 * 400mm, 1 set, lightning down ground, specifications 50mm2,1m, ground terminal, specifications 4 * 40 * 400 + 2000mm flat steel, 1 item. Room electrostatic floor there are others to do we only mine, I would like to ask 1, the room needs to be connected to the number of copper meters? 2, the above products how to do lightning protection grounding specific steps and what to pay attention to. 3, horizontal ground and electrostatic floor between the height of 15cm enough? (Between the ground and the electrostatic floor has a 10cm high trough) is best to give a set of programs, to help me solve the problem to the 100 Thank you more
1, the room needs to be polished copper how many meters? The number: can be as follows: 26m, 140m, the middle value can be. This is not a strict sense of the request, if the budget is sufficient to calculate by 140m. 2, the above products how to do lightning protection grounding specific steps and what to pay attention to. Lay near the electrostatic floor support, pay attention to the copper belt and other equipment and other connections. 3, the level of the surface of the helium for the reclamation of the old rush between the tacit and electrostatic floor between the height of 15cm enough? Adequate, generally recommended best attached to the ground. Not high and low under the floor how to go under the track, maintenance and maintenance of the latter part of the time are trouble.
Weak mine grounding: copper belt laying method There are several cases, 1, if the whole shop is 600 * 600 grid, 40 square will be 140 meters, so the cost is too high, the general project will not do so. 2, you can use the copper machine around the room is about 26 meters, the middle of a thin copper foil instead of doing electrostatic copper network, so a lot of low cost, but also in accordance with the norms to do this is more commonly used method. 3, can also be made "day" field head, so you can save a lot of material costs. Copper tape laying in the vicinity of the electrostatic floor bracket, copper belt and bracket, equipment to make a good connection between. These methods are useful to the project, the specific use of which method, this should be based on the design side or your material engineering offer. Insulators are mainly fixed, insulated copper role, the cost is cheaper. Horizontal ground and electrostatic floor between the helium for the reclamation of the old rush 15cm height enough. The main role of the busbar is to connect all the equipment ground, copper, pooled on the busbar, and then connected to 50 square bus, bus can be connected to the building public ground, the specific needs of how many meters, this should be based on distance. Probably this way. I hope I can help you
