Standard for production

The standard for producing 35kv XLPE insulated power cable with for subway is GB/T 12706-2008 and enterprise standard.

1)About the conductor:

For the hard cable, the conductor shall meet the requirement of GB/T 3956-2008 over the second type annealed bare copper conductor.

For the flexible cable, the conductor shall meet the requirement of GB/T 3956-2008 over the sixth or similar metallic or non-metallic layer annealed copper conductor, usually metallic layer is tin.

2)The Max. permissible operating temperature of the cable is 90°C.

3)The water permeability test for the cable meets the requirement of GB/T 12706-2008.

4)the cable passed the electro-osmosis proof test , without breakdown under 240h, 1800v DC voltage

5)The low smoke performance when burning meet the requirement of GB/T 17651, it is that the Min. light transmittance of the density of smoke when burning is not less than 60%.

6)The PH value of the emergent gas when burning is not less than 3%, and the electric conductivity is not more than 10µs/mm.

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:Wire yellow and green, respectively, that line of fire or zero line
Insulated piercing clamp is mainly composed of reinforced shell, puncture blade, gasket, waterproof grease, high strength bolts, torque nut and cable terminal cap. When the cable needs to be branched or connected, the cable branch line terminal is inserted into the waterproof terminal Cap sets, to determine the main line branch position, with a socket wrench screw clamp on the torque nut, the process of contact with the blade will pierce the cable insulation, contact with the conductor, the sealing ring ring around the cable puncture position, the shell Grease overflow, when the torque reaches the set value, the nut torque mechanism off, the main line and branch line is connected, and waterproof performance and electrical effects to meet the standard requirements of the parameters. T-shaped terminal is composed of insulation base, wiring frame, fire shield composed of three parts, wiring box by the wire clip, screws, nuts and variable frame and other components, wiring clip and wire contact surface was wrapped in the shape of the dentoid staggered structure, With a large area of ​​spinous process, pressure line reliable features. Through the different shapes of the wire combination of each other, can form a double connection, the lower access to the main line, the upper access to the branch line, the formation of continuous "T" -shaped connection, the product is a protective cover, especially suitable for cable trays and cable And other small places to use, can effectively prevent the suffering of the mouse on the line.
Q:The TV shows no signal. The What is the reason for this?
We usually say how many square millimeters (wire) refers to the cross-sectional area of the wire core, that is, according to the diameter of the core calculated cross-sectional area. The larger the cross-sectional area of the wire, the greater the capacity of the power transmission.
Q:Pvc threading tube packaging film how to do attractive, on the grade it? Thank you great god
If the upstairs said that the number of troughs in China. I am doing strong electricity. It is entirely possible.
Q:A sub-eight splitter, behind the link ONU equipment, which also need to add fiber patch panels, or can be directly connected?
Cable and 10kV power line parallel laying the minimum distance of 0.5 meters.
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: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 kind of material should be selected for the fixing bracket of the cable trunking
Should be caused by power line interference. You can buy a shield with the copper wrapped in audio cable and then placed next to the power cord can be, electronic city should have to sell.
Q:Copper core power cable laying cable sets what fixed
BTS is 2G base station, a wireless network consists of N BTS and several BSC, each BTS need to access the BSC through the transmission network. 2G base station transmission interface is mostly 2M interface. SDH (Synchronous Digital System), is a technical system developed by ITU, is a transmission technology. SDH line side (that is, out of the cable) is 155M, 622M, 2.5G, 10G optical interface. Branch side (then business network equipment, including base stations) are more than 2M, FE, GE also has 155M optical interface. DDF and ODF are patch panels, DDF digital patch panels, ODF fiber patch panels. SDH line side of the ODF frame, is received on the outgoing cable, DDF frame service network equipment, in the base station is then BTS. Set the patch panel is mainly for easy maintenance, you can label on the patch panel, each interface business type is very clear. The communication system diagram in the base station is this: BTS - DDF - SDH - ODF - another bureau.
Q:What is the power cable accessories used to do?
When using power, standby power, basically no radiation, can be considered negligible
