Specific property for usage of 110KV~220KV XLPE high-voltage cable

  1. Cable’s conductor highest working temperature is allowed up to 90, and overload when meet an emergency is 130 ,When short circuit (in 5 seconds) the highest temperature is 250

  2. When installing or laying cable, the ambient temperature should be less than -20, and have to give a preheat to cable.

  3. The minimum bending diameter:

                Cable type

Bending diameter

Metal sheathed

After laying

30D0

During laying

40D0

Note: In form, D0 is a real test value to cable’s outer diameter.

 4.  Allowed biggest axial traction force to outer diameter when laying cable (not consider the radial lateral-pressure at bent section) T=K×core NO. ×section (kg), in formula, the coefficient K value should be: the copper core get 7, the aluminum core get 4.

5.   Allowed biggest lateral-press P, when cable is being bent

The single core cable is required P500kg/m.

P=T/R (T is indicated axial traction force; R is indicated radius of bent-wheel), Knowing from above formula, as the traction force is made up by length and weight of cable. So it lets P to applying requirement as above. Then the diameter of bent-wheel should be widened.

6.  Cable laying is not being restricted by drop.

Q:Home improvement, the wire specifications generally how to choose? Lighting, sockets, air conditioning with a few square lines? Ground specifications can be lighter than the line of fire, zero line?
You can use, but look at your LCD TV there is no DVI port or HDMI port, the best use of HDMI port or DVI port, the specific look at your TV size, if your TV support 1080P, it is best to use HDMI or D fans ridicule guest Piji nine Depends on the end VI, because the VGA can only 1080I can not 1080P, with HDMI or DVI display will be better.
Q:Emergency cable T-box and cable distribution box of the information?
The incoming and outgoing wires are electrically connected together The potential is the same, which is suitable for tapping or branch wiring It is common practice to add the number of lines back to the number of times The three-branch cable splitter box, which has three equipotential bonding points on each phase, can be used as a second or two-in-one Cable distribution box contains U, V, W three-phase, three-phase circuit structure is the same, along the row together 2 High-level distribution box High-level distribution box containing switching equipment, both from the ordinary distribution box of the tap, branch, but also from the power supply circuit control, conversion and change the mode of operation The switch fence roughly divides the cable circuit into the inlet and outlet sides, and the potential on both sides can be different The switchgear itself has a larger volume, so the high-level distribution box size is relatively large, the height is generally 14 ~ 18m, the depth of about 09 ~ 10m, the length of the number of switching devices according to the number, M to 24 m The shape of the box is similar to that of an outdoor box transformer, and there are a number of active doors on the shell Some doors are designed for the operation of the switchgear Some doors are provided for the installation or maintenance of the cable connection device The
Q:What does the cable (YJV-5 * 6) mean?
ZR-YJV22-4 * 16 is ZR armored flame retardant power cable, YJV22 copper core PVC insulated steel tape armored PVC sheathed power cable, 4 * 16 is 4 core 16 (mm2) section.
Q:Will the two 16 square copper wire with what specifications of the trunking
If the network cable is shielded with the network no problem, in fact, the main problem is not interference, it touches on security issues, from the truth, the strong and weak electricity can not take a bridge, if you must go inside a bridge, to add metal partitions The
Q:PVC pipe line 6 points and 4 points which big ah?
The bearing capacity of the square millimeter in the wire decreases with the increase of the wire diameter, for example, 1 mm square meter
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:TV tiger when the set-top box when tv / ay look for a look on the platform
Do not have to be so troublesome, such a phenomenon even encountered, is the basement of the air defense, similar to the landlord said the phenomenon can be taken as follows: . first with linen live wire and casing blank. . filled with asbestos cement and compaction, the surface concave sleeve 3-4 cm. . with plugging the king (5 yuan / bag) add water and mix well, smear the surface to smooth. . the work is completed, do not hurt the core and the practice proved no leakage within two years.
Q:Why my home analog TV connected to the digital TV set-top box after the screen is black and white
Cabling in the integrated wiring system according to the network topology diagram to configure how to connect, no network topology is unable to give the correct connection.
Q:Wire and cable manufacturing process (to be detailed)?
Tell you an electrician commonly used "empirical formula": as long as the copper wire, cross-sectional area per square millimeter can be safely through the 4 - 5A rated current; in 220V single-phase circuit, the power per 1KW, the current For the 4.5A or so, in the 380V three-phase balanced circuit, the power per 1KW, the current is about 2A, the above values can be calculated using the physical formula is very close to the results, so the electrician at work, in order to Do not remember those "cumbersome" formula, remember that these can. Then according to this algorithm to know: every 1 mm square cross-sectional area of the copper wire, if used in 220V single-phase circuit, you can safely carry 1KW load through the current, if used in three-phase balanced load (such as motor) Circuit, you can safely carry 2.5KW load through the current
Q:3 (WDZBN-YJV-4x240 + 1x120) cable how to interpret
In fact, this is a wrong model! (WDZBN-YJV-4x240 + 1x120) - 3 cables, each copper conductor Conductive cross-linked polyethylene insulated PVC sheathed halogen-free low smoke Flame-retardant fire-resistant power cable 4-core 240mm² + 1-pin ground protection line 120mm². As we all know, polyvinyl chloride is halogen-free, not "halogen-free". The correct model should be: 3 (WDZBN-YJE-4x240 + 1x120) - 3 cables, each copper conductor Conductive cross-linked polyethylene insulated polyolefin sheathed Halogen-free low smoke Flame-retardant fire-resistant power cable 4-core 240mm² +1 core grounding protection line 120mm².
