Product Description:

Description:
EMT steel couplings are used to connect the ends of two unthreaded EMT conduits together. EMT steel set-screw couplings provide concrete tight connections when taped. Additionally, these set-screw couplings eliminate the need to thread bald conduits to fit old threaded couplings. EMT steel couplings are steel and with zinc-plate surface for excellent corrosion protection in damp location.

Q:How to solve the computer connected to the TV audio problem, how to set the computer and TV audio separation
In accordance with the relevant safety regulations, the power cable should not be parallel to the top of the thermal pipe laying, when can not be avoided, the interval distance should not be less than 1000mm, during which should also take effective insulation measures. Power cable and thermal pipe cross, the thermal pipe insulation layer, the separation distance should be not less than 500mm, no insulation layer should not be less than 1000mm, and in the cross with the insulation board to be protected, the length of the insulation board should not be less than d + 2000mm (d for the thermal pipe insulation layer diameter).
Q:How much of the cable with the switch?
The switch is selected according to the current. General switch = (2-2.5) Current three-phase current = P / 1.732 / 0.38 / 0.8 Single-phase current = P / 0.22 / 0.8
Q:1000 kW 600 m cable to use much
1000kw ah that with three groups of 400-ping line should be no problem
Q:5 air conditioning can be used 4 square cable
You do not use the 9V power supply, a long time will burn the router.You'd better measure the original adapter voltage, if you want to extend the power cord, it is best to use a thick line of reliable connection, you can not start now, you can not start Depending on whether the extension line is too thin, causing the voltage drop too much.It is necessary to extend the front end of the adapter can extend the 220V power cord.
Q:Is the cable head made of every building?
First, the cable production and installation of each building has. Second, the cable terminal set of waterproof, stress control, shielding, insulation in one, with good electrical and mechanical properties, in a variety of harsh environmental conditions for long-term use. With the advantages of light weight, easy installation and so on. Cable terminal is widely used in electric power, petrochemical, metallurgy, railway ports and construction and other fields. Third, the production process: including the following: . cut off the excess cable; . the cable protective layer of the stripping; . conductor connection; . wrapped around insulation (or shrink pipe); . install the connector shell; . ; . for sealing treatment.
Q:7 kilowatts of electricity with what specifications of the wire
1 square millimeters can flow 4A current, 1KW380V, then the current is about P = UI about 2.6A7KW, 380V, then the current is about 18A, each with the line to share 18/3 = 6A2.5 square mm of copper on it. Of the area need to take . probably 6 level. V is probably 7KW220VI = p / u = 7000/220 = 31A. Then need 10 square millimeters of copper.
Q:What is the type of pipe that is marked as KBG pipe?
Will the general power cable control cable can do the largest square...
Q:25 square copper cable how much money one meter?
3 plus 1 64.13 yuan, 3 plus 2 75 yuan, 4 plus 1 81.38 yuan contact to see my registration name
Q:Decoration doubt, what kind of wall can not open the horizontal groove?
Power board problem cost 10 less than the general maintenance received you 150
Q:How to distinguish how many pairs of cable with a large heat shrink tubing
Yellow line is video, red and white are audio, you can only pick one!
