Product Description:

Product Introduction:

It is mostly used in the electric controlmonitoring  loop and protection system with rated voltage up to 0.6/1kV outside the  shield of the nuclear power plant which controls emergency stop of the  reactor, isolating the security shield, emergency cooling of the reactor  core, removing the afterheat of the reactor and the shield, preventing  from letting the radioactive substance into the environment when the  earthquake does not exceed the load for that.


 

Characteristics

1Longevity, which is designed to be used for over 40 years.

2Good performance in heatproof aging and atmosphere aging resistance.

3Good performance of component compatibility and tear resistance.

4Good flame-retardant capacity.

5Double  layer of insulation: It gets good performance both in electric  insulation and flame-retardant from improving the structure of the  insulation.

6Isolation  +single electric insulation: It’s certain that the capacity of  flame-retardant is good and the electrical capacity is improved by  adding extra structure of isolation.

Q:The wall was sideways opened a trough how to do ah?
The copper core grinding first to the copper core on the flux (rosin or solder paste)
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:Which has, know the power of the electrical, choose the cable formulas. And explain it
Basically are refining, the wax is also used, the high cost of particles
Q:What is the difference between a pre-branch cable and a punched clip?
Cable bridge is used to support and protect a variety of cables, in power plants, substations, large industrial and mining enterprises, high-rise buildings are widely used. But are a one-time infrastructure in place, usually no longer replace and add.
Q:Apple mobile phone does not support this charge when charging this thing how to charge
Can not! "Power Cable Design Code" Article 5.1.3 provides that the number of stents by the channel space constraints, 35kV and about the adjacent voltage level of power cables, can be arranged in the same layer of stent. 10kV power cable (actually 8.7 / 10kV) and 380V power cable (actually 0.6 / 1kV) in the interval between the 6kV and 3KV two voltage levels, not the adjacent voltage level, can not!
Q:Power Cable Check Well b-type covers show what?
B-grade steel fiber concrete check covers are used for motor vehicle driving, parked urban roads, highways and parking lots C-grade steel fiber concrete check covers for slow lanes, residential quarters and sidewalks D-grade steel fiber concrete inspection covers for green belts and motor vehicles can not travel, parked lanes and venues
Q:What are the requirements for the spacing between the strong and weak wires?
Notebook does not have the opportunity to DIY. The reasons are as follows: Notebook motherboard non-versatile motherboard, the shape of the motherboard, positioning holes, screw holes are not uniform standards, each manufacturer's motherboards are their own engineers and then open factory production model. Notebook shell corresponding to the interface location, type and screw hole location is with a specific motherboard supporting.
Q:Ask you a question: how the computer CD-ROM power supply 5V and 12V two lines? Another audio and video cable which group?
The final settlement is the completion of the drawings, the first to complete the map on the right, clear
Q:How to determine whether the square of the cable is standard
Depends on your number is not arranged in order, the general building room when the patch panel and the user board number is one to one correspondence
Q:3 (WDZBN-YJV-4x240 + 1x120) cable how to interpret
3 (WDZBN-YJV-4x240 + 1x120) cable is a low smoke halogen-free flame retardant (B grade) XLPE insulated - PE sheathed copper core power cable. The model of the cable is usually composed of eight parts: First, the use of code - not marked as the power cable, K for the control cable, P for the signal cable; so the power cable. Second, the insulation code -Z oil-impregnated paper, X rubber, V polyvinyl chloride, YJ cross-linked polyethylene; so for the cross-linked polyethylene insulation. Third, the conductor material code - not marked as copper, L is aluminum; therefore copper. Four, inner layer code-Q lead package, L aluminum bag, H rubber sleeve, V PVC jacket; so for the PVC jacket. . derived code-D no drip, P dry insulation. Sixth, the outer layer code. . special product code-TH wet tropical, TA dry tropical, ZR- (flame retardant), NH- (fire), WDZ- (low smoke zero halogen, enterprise standards); so low smoke halogen-free flame retardant The . rated voltage - unit KV; general cable are marked, the problem is estimated to write missing 0.6 / . the use of: rated phase voltage of 0.6KV, line voltage of 1KV. In the cable, 4 * 240 + 1 * 120 that there are 4 core 240 square copper wire, a 1-core 120 square copper wire.
