Product Description:

The product is made  up of the compacted copper, aluminium(aluminum alloy) conductor,inner shield,  climate-resistant insulation material and outer shield.It has simple structure  and reliable. It has both excellent peoperties of the power cable and good  physical peoperties of the aerial cable. By using the climate-resistant  insulation material, the product has the excelent properties of resistance to  air aging. Compare with the bare wire, it has the good characteristics such as  smaller laying distance, higher reliability. It is suitable for using in the  bulidings, brushhland and bad weather zone.


1)       There are three rated  voltage:1kV10kV35kV

2)       Allowed long-term working temperature: PE  insulation--70, PVC insulation--70, XLPE insulation--90.

3)       When short-circuit(the longest time is not  more than5 second),the highest temperature: PE insulation--130, PVC insulation--160, XLPE insulation--250.

4)       The enviroment temperature for laying  should be not lower than -20.

5)       The working enviroment temperature is  from-40to +40, the relative humidity should be not more than 90% in rainy  season.

6)       Permitted bending  radius

Cable with rated voltage 1kV and below: outer diameter of the cable  D25mm,bending  radius should be not less than 4D.The outer diamter of cable D>25mm, bending  radius should be not less than 6D.

Cable with rated voltage 10kV, 35kV: single core cable:  20x(D+d)±5%

                                                            Mutiple  core cable: 15x(D+d)±5%

In which: D-the actual outer diameter of the cable,mm

               d-the actual  outer diameter of the cable conductor,mm

7) Derivative  products

  a. Aluminium-alloy aerial insulated  cable        b. Parallel bunding aerial  cable

  c. Water-blocking aerial cable                        d. Water-blocking  bundling aerial cable

  e. Non-standard insulated aerial  cable

Q:PVC pipe on the GV.215-16 (C) What does it mean
SC pipe welding fluid with welded steel pipe, the general thread connection, or casing welding connection. TC pipe is a thin-walled steel pipe, referred to as wire tube, you can thread connection, tight connection, buckle type connection, not casing welding connection.
Q:Calculation method of wire and cable outer diameter
Usually check the table, in the cable samples or manual check.
Q:Water and electricity installation drawings in the kz on behalf of what material of the threading tube
HDMI interface common in some new TV, which is called "digital high-definition multimedia interface", mainly for the transmission of high-quality, lossless digital audio and video signals to high-definition television, the maximum bandwidth of 5Gbps In addition, There is also an interface you need attention, this interface is called "DisplayPort", it can provide the same function with the HDMI interface, and can provide bandwidth up to 108Gb / s, much higher than the HDMI interface More importantly, DisplayPort is free Standard (HDMI charges), almost all of the personal computer manufacturers and graphics card manufacturers have expressed support for this interface
Q:Engineering materials inspection, all types of cable wires should be issued a test report?
Is the aluminum core armored cable for outdoor high pressure conforming to the specification
Q:Cable WDZ-YJFE2 (4X185 + 1X95) what does it mean
Bracket spacing of the general level of not more than 2m, vertical not more than 1.5m according to the number of cable the number of levels can be used 1.5m a vertical 1m a relatively insurance
Q:Construction of hydropower embedded pvc pipe after the solidification of the pipe after the flat tube
Cable model NHYJV3 * 25 + 2 * 16 its name is: fire-resistant cable. NH ----- on behalf of fire. YJV ----- XLPE insulated PVC sheathed power cable. 3 * 25 ----- 3 cable cross section is 25 square (for 3 phase line with). 2 * 16 ----- 2 cable cross section is 16 square (one for the neutral line, one for the ground line). Fire-resistant cables are generally used for TN-S power supply systems (five-wire).
Q:What is the difference between a shielded cable and a control cable?
I do not know, I do the task, although we also engage in cable
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!
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,
This is generally not very good replacement, and you ask is not very specific, the proposed problem is more clear, more convenient for you to answer.
Q:What is the difference between VV22 and VV62?
Cable flow current is to be hot, look at the table with a look at the current is normal, the current is consistent with the cable configuration. Laying the environment is normal.
