Introduction:

As the economy rapid  development, the high buildings pile up one after another. The modernizing  hospital, hotel, living house, highway and bridge are spring up. The capacity of  the distribution system and the illumination system increase continuously, also  with the complexity.The traditional method of the line distribution is directly  adopted the common bus-bar groove, this kind of method makes the construction of  long duration, high cost, the joint infirm, easy to occur the breakdown,  occupying the large building area, the joint does not bear damp and corrosion.  Thus, in the late of 90’s, the minority of developed countires have created the  new power supply system of prefabricated branch cable, with low-voltage. This  system is made up with the in special cable, distribution box,power etc. It has  the characteristis of the power supply dependable,cheap price, simple  installation,the requirements of the environment is not so strict,  no-maintenance, etc.

The prefabricated branch  cable developed by our commany is as the special cable of this system. According  to the customer’s demands, the needed quantities of branch cable are connected  in the set position of the main cable. When construciton, it is very convenient  that the hook hangs the cable drum in order to reel the cable out evenly.  Through the special treatment of the branch joint, it has the property of power  supply dependable and certain waterproof.

Product Characteristic:

Excelent reliability of  power supply

1)       There is no joint on the  conductor of main cable, thus it has a good continuity while the fault points  reduced.

2)       The joint of branch cable  is reasonable designed and manufactured with advanced technology. The contacting  resistance is very small, never influenced by expanding with heat and  contracting with cold.

3)       The branch joint is  shaped in a short time, thus it prevented the conductor from exposing in the air  for a long time which will cause the oxidation and result in the change of  contacting resistance.

4)       For the branch cable,  there are the strict technical standards, inspection needs and quality assurance  system.

Specification:

By comparing with bus-bar  groove, it can reduce the engineering cost while its technical and economic  targets are so high; the comprehensive economic benefits are  obvious.

Q:How to connect the power cable pre-branch connector
Pre-branch cable detection: a In addition to routine pressure test, it is necessary to increase the insulation resistance test, with a shake table can be completed in each branch after the completion of injection The table measures the insulation in the finished product After the pressure is also used to detect the insulation of the table to prevent the water cooling process in the branch of the water caused by short-circuit, the general AC voltage test can not detect, can only increase a set of table detection process B Core conduction detection, In each branch body should be tested with the trunk of the conduction test to prevent the production process due to improper operation caused by the branch and the trunk circuit
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:Fourth, what causes the power cable fire accident
Once the cable in the event of fire, the fire ferocious, rapid spread, in the burning will occur when a large number of harmful gases, resulting in fighting difficulties
Q:Power cable 5-color line, respectively, what color, what role?
YJ: cross-linked polyethylene insulation V: PVC sheathed 22: steel tape armor 8.7 / 15KV: rated voltage: 8.7 / 15 kV 3 * 300: three conductor cross-section of 300 square copper conductor Another: such as YJLV Is the aluminum core. Here is not marked what the material is conductor, you can default to copper conductor.
Q:The UV lamp is fitted with ozone and no ozone difference
. like the computer boot fast, the best way is solid state hard drive, followed by the win. the system is very good, the interface is also familiar with the boot fast, especially the new browser edge than a lot stronger; . if you now computer The monitor is also good, and now the computer's hard drive can be taken down to the new computer above, then 3000 yuan can buy very very good, desktop. If the notebook is about 4500 or so relatively high cost. . do not recommend the configuration of their own one by one to buy accessories, it is recommended that you look at the top of the machine installed Taobao business, they rely on the volume, not only to ensure that the genuine accessories, the price is relatively cheaper to buy their own, And wiring installation are also professional. And they are equipped with win7 is free to upgrade to win. very good. I just bought a few days ago a machine, monitor and hard drive or use their original, with the host with the solid-state hard drive as a boot disk, their hard drive as a storage disk, spent a total of . the performance is very good.
Q:What is the difference between a trough bridge and a tray tray?
Many, with the cable where the requirements should be used bridge.
Q:The difference between the instrument cable and the low voltage power cable
In this only said home improvement commonly used, the pipe is basically direct, elbow, tee, the price is 5 points / only.
Q:Calculation method of wire and cable outer diameter
Usually check the table, in the cable samples or manual check.
Q:1omoons / days sensitive quad-core network set-top boxes can be used on old-fashioned televisions.
Network set-top box does not require a computer, only need to follow the operating manual set-top box and TV connection, and then boot the wired / wireless network configuration, with set-top box software can watch the video program. 4M do not see the basic high enough, but now the Chinese network is shared bandwidth, if the use of many people may be cardton
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
