- Q:Use the network cable to do the telephone line to play the distribution frame
- See you specifically what electrical appliances to take what is, 1 ² BV line can be connected to 3 kilowatts, but have to take into account the voltage and start the current, please add detailed friends ~
- Q:Will the steel structure of the bridge laying the problem?
- Attenuation is too large, it is recommended to buy a general but can be used. Wireless card generally does not exceed 3m line.
- Q:What is the meaning of the power line of the computer?
- Yellow / green color line specifically for the protection of the ground! Other lines of color are not required.
- Q:Why some cable tray to spray, what is the role?
- Who provided the more to the sub-gave to whom, thank you for helping
- Q:How to prevent the wire from catching fire
- . in the cable when it is necessary to use the appropriate specifications of the wire, the diameter of some of the best copper . do not use too much power of the electrical appliances, so that the wire overload operation . the installation of leakage protection switch can effectively prevent short circuit Causing fire
- Q:All the network through the set-top box plug in the power TV screen is not displayed
- It seems not right, so high-tech. Then you might as well buy a wireless network card,
- Q:Is the POE switch connected to the network camera via the patch panel to affect the power supply function?
- Power cable and control cable in a bridge laying, too close will be affected, especially in the automation of the instrument, the speed accuracy is not too high for the inverter is not big, will not burn potentiometer
- Q:What is the safety distance between the bridge and the bridge?
- Cross-sectional area * length * density = mass such as: 1 m YJV-1KV-3 * 90 cable 3 * 90 * 1 * 0.0089 = 2.403KG
- Q:2.5 square wire how long is it better?
- The easiest and safe way is to buy a standard patch panel, to the big supermarket and other regular stores to buy authentic bull card, the bullet can be the first card. Note that your wall is 16 An outlet, the water heater on the plug to see what is the big, if it is 16 security, then buy a direct 16-inch wiring board can be, if the water heater is 10-amp (2.5 square Of the line, usually 10 An), it would replace the wall outlet or water heater plug, otherwise the size is not the same, can not be inserted.
- Q:How to choose the type of street lamp cable specifications, anxious
- In addition, in addition to protecting the waist, sleeping hard bed for the elderly with heart disease is also very important.
