Q:Why this cable has not yet been certified
The manufacture of wire and cable is completely different from that of most electromechanical products
Q:When pouring concrete is how to put the tube
Oh, the pipeline is poured before the layout according to the design drawings.
Q:Galvanized wire tube buried to do anti - corrosion do
Galvanized pipe itself with anti-corrosion coating, you can not do anti-corrosion.
Q:Where should the inner diameter of the plastic tube of the cable be at least the number of times the outer diameter of the cable?
You are not very clear: how to start again? 300μF capacitor is normal? If the sound is normal (very small) after no-load start, the cable and the motor temperature are normal, the coil can be judged to be normal
Q:Wire printed on the word what way to erase
Wipe with water that day. You can also use ink thinner
Q:2.5 square copper (green, with the threading tube) can withstand the highest power of several kilowatts,
Should be the line group: lighting a group of 2.5 square millimeters, an ordinary socket a group of 4 square millimeters, air conditioning a group of 6 square millimeters, kitchen and bathroom appliances a group of 4 square millimeters, so that after the down is not enough to put a separate group You say the high-power electrical outlet, the line to the square of the square mm to see your home how high-power electrical appliances, but advise you to use these high-power electrical appliances before the first to determine its current good, More than your home appliance load!
Q:Home leaked, installed in the floor below the wire was blisters will have any security risks? How can the water inside the pipe to dry
Can do so, it seems that less a HDMI high-definition line
Q:Fiber optic cable split box, integrated wiring box, cable terminal box, cable transfer box difference
Outdoor fire line must use fire-resistant KVV cable, wear pipe protection.
Q:How to distinguish between power cables and electrical wiring on drawings
After the opening is not, if not open like a downstairs to delete the C disk file on the line, if the boot is necessary to set up, sit down little hands and feet.
Q:What is the difference between a kbg threading pipe and a PVC threading pipe?
You should be said: 2-way cross-linked polyethylene insulated PVC sheathed cable 4 core 185 square millimeters, SC is steel pipe, diameter . FC is laying method dark cover the floor or floor. Personal opinion, hope to help you!
