The bridge has a combination of cascade, tray, grid, slot, etc., which in turn with the trough bridge and metal trunking is most similar. And the project cost in the trough and the bridge of the unit price difference of dozens of pieces of one meter, so it is very important to distinguish them ... ... Now a construction team with 200 * 100 slot cable, and some of the floor of the feeder 200 * 100 of the groove with 100 * 50 slot laying. The material of the groove looks like stainless steel, there is no corresponding turn accessories (the term how to call?) Cable or branch line at right angles, between the two slots are not connected to the corresponding hole, the upper and lower cover seal. I ask the money when the "slot" is the price of the bridge to the metal trunking or to the money? More
The bridge is used to lay the power cable and control cable, the trunking is laying wire and communication cable; bridge is relatively large (200x100 to 600x200), the trunking is relatively small; bridge bending radius is relatively large, ; Bridge span is relatively large, the trunking is relatively small; fixed, installation in different ways; in some places, the bridge is not covered, trunking is almost all covered with a lid. The trunking is used to track, the bridge is used to take the cable.
In fact, as long as the installation of a water heater on the line, than the gas is relatively safe, easy to install, but also gas gas
I do not know if you have windows in the kitchen, ventilation is good, in fact, or the installation of electric water heater is simple (because the installation of gas water heater, change the gas pipe must be approved by the gas company), directly installed in the bathroom, and then connected to the kitchen, You can.
Every morning to take a bath, do not want to wait, of course, gas or natural gas water heater, (note that natural gas and gas water heater to buy when the points), the most things or ask the next solar water heater manufacturers, the original can install electric tube. If you are used to take a bath, the kitchen and wash basins are not hot water, then mind the direct installation of electricity in the bathroom, direct installation of the pipeline bath, save the pipeline.
