Product Description:

. Product Properties:

1. This product should comply with GB/T12706-2002 national standard.
2. Partial discharge test: when rated voltage Uo is 18kV and below, the cable discharge should be less than 20PC; when rated voltage Uo is more than 18kV, the cable discharge should be less than 5PC.
3. 20 ℃ conductor DC resistance: Copper core ≤ 0.017241Ωmm2/mo Aluminum Core ≤ 0.028Ωmm2/m.
4. The combustion performance (flame retardant cable) should be tested in accordance with GB/T18380-2001 standard.

II. Characteristics of usage:

1. The maximum long-term temperature of the cable is 90 ℃.
2. When the cable is laid out, the ambient temperature should not be less than 0 ℃, and the bending radius of armored cable should be no less than 20 times the outer diameter of the cable.
3. In the event of short circuit, the maximum temperature of the conductor should not exceed 250 ℃, and the lasting time of the conductor should be no more than 5 seconds.
4. The laying temperature should not be less than 0 ℃.
5. In event of short circuit, the maximum temperature of the conductor should not exceed 160 ℃, and the lasting time of the conductor should be no more than 5 seconds.
6. The cables are applied to transmission and distribution systems with rated voltage of 0.6 / 1,1.8 / 3,3.6 / 6,6 / 6,6 / 10,8.7 / 10,8.7 / 15,12 / 20,21 / 35,26 / 35KV.
7. YJV and YJLV are applied to indoor and outdoor installation, and can withstand a certain degree of laying traction, but can not withstand occasions with mechanical external force. Single-core cables are not allowed to be laid in the pipelines with ferromagnetic materials. YJV22 and YJLV22 are applied to underground laying, can withstand the mechanical external force, but can not afford a big pull.

Q:The wall was sideways opened a trough how to do ah?
PVC pipe. Iron pipe, trunking, bridge, hose, and so on. The The PVC pipe, trunking generally the most common, used in the kind of request is not very strict, not much bit line. Capital is not high, low cost, iron pipe bridge is mainly used in fire strict buildings, shopping malls, high cost, security, line points and more use of bridge hose used in the line out of the floor to the desktop section. Nice point of the ceiling. Overhead floor, are suitable for placement is not comprehensive, personal experience
Q:Copper core power cable models which several kinds
They have two kinds of total use, one is the transmission current, one is the transmission signal
Q:110 voice patch panel directly to the telephone line can be connected to it
See home improvement or tooling, home improvement we will be buried in the trench below the pipe. Also need not particularly out of the picture, not so high demand. All the lines of the tooling must take the bridge, that is, from the ceiling to go, must be strong and weak to separate a distance, the line can not exceed 40% of the tube (tooling home improvement) to no longer clear the label is not OK, simply can not repair. And this is the national norm. Of course, the construction process of a lot of strong power or take the ground, but this is inside the floor. Can be drawn directly.
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:Power cable casing buried what are the requirements
1 It is advisable to select the route to lay the cable in a suitable way: 1 Avoid the area where the corrosion of the acid, alkali, or stray current is seriously affected by electrochemical corrosion
Q:The UV lamp is fitted with ozone and no ozone difference
Clean the copper wire to be welded, and dip a little solder paste or rosin before welding.
Q:How to find the phone number on the 110 patch panel
Cable ends should be marked with cable head symbols, the middle line should also be different from the ordinary wiring. Bv at the beginning of the general wire, with YJV or vv is generally a cable, but not limited to these
Q:The difference between the instrument cable and the low voltage power cable
Meaning the cross-sectional area of the wire, the unit is square mm; for example: 4 square copper wire, the cross-sectional area of the wire is 4 square millimeters, copper wire;
Q:30 on the large number of cable how to fight on the 110 patch panel, how to order, please inform, thank you, which
I have to integrate a graphics card, you buy a separate graphics card is really a waste of money now I also listed, showing a lot stronger than the 2100 performance, and the market in the low-end discrete graphics upstairs you upstairs a lot of results Even a display did not give people with the price exceeded
Q:Dell laptop plug in the power supply usb can not be used, how is it?
It is generally not required to do so because the battery on the computer side of the charge side of the use of all right
