1.  The cross-linkage PE insulated and wrinkled aluminum wrapper waterproof PVC sheathed power cable.

Type

YJLW02, YJLLW02

Specification

240mm2~3000mm2

Voltage

110~220KV

Suitable for the places with a higher underground water level and to be used underground, in the tunnels or pipes. Such cables bear a bigger pulling force and pressure.

2.The cross-linkage PE insulated and wrinkled aluminum wrapper waterproof PE sheathed power cable.

Type

YJLW02, YJLLW02

Specification

240mm2~3000mm2

Voltage

110~220KV

Usage

Suitable for the places with a higher underground water level and to be used underground, in the tunnels or pipes. Such cables bear a bigger pulling force and pressure.

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

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

2.       When installing or laying cable, the ambient temperature should be less than -20°C, 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 set ion) 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 P≤500kg/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:How do I extend the power cable for a 1500W heater.
Assuming the current cord is rated properly, if you extend it, you will need to make the extension one size larger to avoid voltage drop, and overheating of the wire. Doing what you suggest is likely to produce a stiff section that is awkward to handle. I prefer to have a plugin connection so if someone trips over it or pulls a chair with the leg behind it, it will unplug instead of dragging the heater.
Q:Universal laptop power cord...can somebody recommend a good but inexpensive universal power cable for a laptop?
Laptops each have different power cords, because they have different connections to the laptop itself, so there's no one universal power cable. However, you can easily buy generic powercords for your specific laptop that are cheap. Just go to a site like OKorder and search for your laptop name.
Q:Can I use the PSP Power/Recharge Cable with the PS2 Slim?
No you can't, the PSP AC adapter has a lower volt ammount then the one required to power a PS2 So your going to have to play your PSP while you wait for the replacement PS2 cord to come to come
Q:Double sided AC power cable pins?
If the equipment is under warranty, I might consider taking it back and complaining. If not, the hardware store is your recourse here. Good luck!
Q:What is the installation specification for the cable tray bracket?
Be careful is right, but it is not necessary to be timid. Need to do so: . ask the district property, if the best road distribution map, read the drawings, you know where the cable, where not. . ask your home decoration of the electrician, he knows the most where your house where there is a wire decoration. . the general wall cabinet installed relatively high, as long as the bottom of the socket to avoid, generally all right.
Q:where can i put my amp power cable through my bulk head in my 1999 ford mondeo?
Find the main harness going through the fire wall and follow it
Q:How can I find the optimal length needed for a power cable to connect two poles using catenary concepts?
The web page provides very thorough information and rigorous mathematical treatment relevant to the answer you seek. But it is just too much all at once to digest. So take it piecemeal, one bit at a time! First, you must realize that the sag of the cable is the single most important design parameter and strict attention to cable weight determines the optimal length. The equation of the catenary is the precise model but a parabolic approximation may work. (parabolic approx.) ymax = (3wl²) / ³√(64EA) P = wl²/(8ymax) Where ymax is the maximum sag l is the unstretched length w is the weight/unit length E Youngs modulus A Wire area P axial tension the curve is a parabola, which is a good approximation if the depth of sag is no greater than 1/8th of the span. Use the second equation to derive the induced tension P. H:=WL²/8S S:=WL²/8H L: distance between support S: Sag at mid-span H: tension (horizontal component of tension) The tension depends purely on the loaded geometry and the weight per unit length.
Q:Running amp power cable outside of vehicle?
You'll have no problem running the power wire thru frame rails the cable is designed to weather the elements under the hood so it will work under the car just make sure to secure it solidly in as many places possible so it can't droop and snag on road hazards
Q:My Acer laptop shuts down when I moved the power cable?
sensitive power supply connection i guess
Q:what happens when A power cable of copper is stretched straight between two fixed towers.?
Change in length=(coefficient of expansion)(original length)(change T)= (.0017)(chose your favoret length, I chose 100)( -128 because T is decreeing)=-21.76 Strain = (change in length)/(original length)= 21.76/100= .2176Pa (for simplicity's sake I dropped the negative, rember the wire is in tension) Stress = (youngs modulus)(strain)= (11•10^10)(.2176)= 2.3936•10^10 Pa The UTS (2.4•10^8)<(2.39•10^10) so there is definitely necking and because of the difference most likely there was failure long ago.
