I would like to ask you, you generally do steel plant, how to lay the bridge feel better? I have some drawings, 1. Some of the bridge laying in the I-beam column, 2. Some of the bridge laying on the wall, 3. There are bridges along the steel roof truss lay, I went to know the appearance of steel roof truss, There are winding, chord, the middle of the abdomen is used to insist on the upper and lower sides, but that is along the winding, roof truss sometimes not linear level, sometimes for example triangular steel truss, not the level of the winding how to walk it?

Can use 2.5 square copper wire. Power line cross section is not safe, big too wasteful.
What is the number of air conditioning is usually called, according to the air conditioning power consumption to estimate the amount of air conditioning cooling. In general, the habit of using a equal to 2500W of cooling capacity (that is, 25 models), 1.5 is about equal to .3500 amount (that is, 35 models). 1.5 for 16 to 26 square meters. 4 square of plastic copper wire can be 10kw enough to take the green line. 2.5 square steel wire can accommodate 3500W can also be. Preferably 4 square meters of plastic copper line is good
