Product Description:


    This  product is used in the 1E class K3 category nuclear power station  signal control system outside the secure covering with voltage up to  0.6/1kV. In which system it can insure stop of the reactor under the  earthquake load, separation of the secure cover, cooling of the center  of reactor emergently, heat vent in the reactor, and can prevent the  radioactive particle to enter the surrounding environment.

Q:Calculate the control cable under what circumstances the cable terminal needs to be calculated
" Why should the closed wall or protective wall closed on the second side of the closed junction box? This need to understand if you do not add this closed junction box, what kind of harm Civil air defense project in the closed wall is divided into the clean area and the area of ​​the infected area, and the wire tube in the thread after the inside is a cavity, directly through the wall to communicate with the cleaning area and exposed areas, so wartime works outside the dyeing The poisonous air can penetrate into the clean area through the cavity inside the wire tube, which is harmful to the personnel inside the project And the installation of a sealed junction box, you can thread in the line after the box filled with sealing material to block the tube cavity connectivity This is why the electrical safety pipe in the air defense project must pass the closed wall or protect the closed wall when the two sides must be closed in the closed junction box reasons
Q:How to convert the computer's audio and video to cable TV signals. Through the cable television transmission to the 40 TV (hurry)
In general, a 42U cabinet to 200 information points within the appropriate
Q:What is the difference between a pre-branch cable and a punched clip?
The structure of the PV cable is shown in the table. The difference between the ordinary cable and the PV cable is analyzed: The common cable can be seen from Table 1 that the conductor and the PV cable used are consistent. ordinary cable insulation and sheath can be seen from Table 1 different from the photovoltaic cable. Ordinary cable is only suitable for use in general environment. the advantages of photovoltaic power cable: high temperature, cold, oil, acid and alkali salt, anti-ultraviolet, flame retardant, environmental protection, photovoltaic power cable is mainly used for harsh environment, the service life of more than 25 years.
Q:Pvc threading tube packaging film how to do attractive, on the grade it? Thank you great god
The control cable that transmits the differential signal, the cable core needs to be stranded. The other with the same general control cable. Search for "Industrial Automation Integrated Cable Solutions".
Q:1omoons / days sensitive quad-core network set-top boxes can be used on old-fashioned televisions.
Set-top box on the TV next to a method is to use the network cable connected to the computer, another method is in the set-top box next to a wireless router, the computer can not be used to use the network, if there is no dark Set the network cable, you can also use the power network adapter to the network set-top box out of the network cable connected to the power adapter, through the power line to connect the computer Internet. As long as enough 4M, regardless of rural or urban are the same, I now use the 4M broadband, basically not card.
Q:Lighting wire, I do not know is it. The When to use BV1 * 2.5, when to use 2 * 2.5, when to use 3 * 2.5, when to use 4 * 2.5,
It does not look good, but also affect the wallpaper, wallpaper, in full swing, and then from the chain reaction, then it is worthless, it is recommended to use decorative decorations decorated, perhaps alone for more suitable wallpaper pattern or color ... that does not affect the wallpaper Can also play a decorative effect ... Thank you
Q:What is the difference between the control cable and the compensation cable?
The reason why the wire outside the casing, is to protect the wire insulation from external damage. And the wire laying in the cable tray. The bridge has been gas to the protection of the role, so no longer outside the casing
Q:What is the power cable accessories used to do?
Do not know what you want to ask? What about your situation? Normal or pregnant? Normal this radiation does not affect what, if it is pregnant, this is far away from the best. Pregnancy is most needed to stay away from the microwave!
