Q:The living room to the bedroom cable does not work
Submarine cables and ordinary power cables are used for power transmission, the general power cable in general steel armored after squeezing the outer jacket can be, the submarine cable in the outer jacket outside the cover and mixed with asphalt Steel armor layer to increase the mechanical strength and corrosion resistance when laying. Electrical technical parameters and the same as the ordinary power cable, the main consideration to provide cable laying when the submarine channel conditions and the sea environment. Another large length of the submarine power cable also consider the cable intermediate connector technology is reliable (in case of accidental damage or body failure). The difference between the submarine cable and the cable are said, if the need for submarine cable, in addition to the basic provision of electrical performance and other parameters need to provide laying environmental factors such as buried depth, sea water temperature, sea soil thermal resistance coefficient The
Q:Emergency cable T-box and cable distribution box of the information?
1 Ordinary distribution box There is no switch device in the general distribution box
Q:Calculate the control cable under what circumstances the cable terminal needs to be calculated
You say is the power supply power? Is not the power supply voltage! Power supply is W, that is, tile. Power power is insufficient, it is said that the components will accelerate the aging, aging components are easy to burn, components on the motherboard, of course, is burning the motherboard Oh, and power supply is also easy to cause computer instability. Crash, restart .... and so on. If your power is not enough power, it should be for a larger power and is guaranteed quality power such as Hunt, the Great Wall and so on. General 250-300W power supply on it.
Q:What is the difference between a shielded cable and a control cable?
If there is a number of casing is the number of lines marked, if the line before the iron circle is a small nose, line nose in addition to a small circle and fork, and fork almost look.
Q:Engineering materials inspection, all types of cable wires should be issued a test report?
Is the aluminum core armored cable for outdoor high pressure conforming to the specification
Q:Can cable TV signal lines and network cables be placed in the same line when upgrading? What happens if you are in the same line? Thank you.
Your USB cable is really different. People are red and black is negative, green and white is the data transmission.
Q:The difference between the instrument cable and the low voltage power cable
Meaning the cross-sectional area of the wire, the unit is square mm; for example: 4 square copper wire, the cross-sectional area of the wire is 4 square millimeters, copper wire;
Q:Calculation method of wire and cable outer diameter
(In accordance with the power cable, single-core cable sheath of the nominal thickness should not be less than 1.4mm, multi-core cable nominal thickness should be not less than 1.8mm), the thickness of the jacket, 2. On-line measuring sheath thickness: Sheath thickness = (circumference after extrusion of the jacket - circumference of the jacket) / 2π or sheath thickness = (circumference after extrusion of the jacket - before the jacket Circumference) × 0 .. Insulation thickness of the most thin point: Nominal value × 90% -0.14. Single core sheath the most thin point: Nominal value × 85% -0.15. Multi-core sheath thinnest point: Nominal value × 80% -0.26. Wire armor: Number of roots = {π × (inner sheath outer diameter + wire diameter)} ÷ (wire diameter × λ)
Q:1omoons / days sensitive quad-core network set-top boxes can be used on old-fashioned televisions.
Pipe protection cable to wear metal hose, metal hose and galvanized pipe to use metal lock connection, the connection can not pull the light pull on the line. If there is no metal hose or no metal lock, in the pipe when the pipe toward the cable to the appropriate bending, preferably in the mouth of the cushion cable skin, and then use the electrical adhesive tape sticky, sticky. After the nozzle cut with a polisher smooth grinding, the provincial scratch cable.
Q:What is the difference between public relations firms and media companies?
What is the lighting type busway ah, long experience. Lighting distribution box dedicated busbar?
