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

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℃
When installing or laying cable, the ambient temperature should be less than -20℃, and have to give a preheat to cable.
The minimum bending diameter:

Cable type Bending diameter	Metal sheathed
After laying	30D₀
During laying	40D₀

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 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:lost the original cable at a gig, but I have another cable. the outlet on the Behringer guitar amp reads quot;Use only with 250V fuse, but right above the outlet it reads 220-240 with a upside down triangle next to it (not sure if this represents volts or not...I know obviously V stands for volts, but this is a upside down solid triangle.)My power cable/cord that i found reads 10A 250VI know i should probably purchase one direct from the manufacture, but that is not possible right now. I have a gig coming up this weekend.thanks for any help.I also mention the original power cord was a two prong (that went into the outlet) - the one i might use is a 3 prong. will this still be safe? It does fit into the back of the amp perfectly.: Assuming you're in a place where the outlets provide 220 to 240 volts, it's fine. The 250 volts on the power cord just means it's good for *up to* that.

Q:Ok A few months ago i bought parts for a brand new pc and recently got the video card and well the power supply PCI-e cable is a 6 pin and the motherboard requires a 4 pin. A friend said there are adapters but i've only seen one and it was not very good rating wise. So I'm looking to find out if there are adapters or if i need to get another power supple.: See how that one is a 4pin connector and has 2 extra pins that are snapped on the side?

Q:can you use just one power (positive) cable cut it and use the rest for your negative: Power cable and ground cable is the same thing, it conducts electricity exactly the same so you an use your scrap wire for a negative but i would reccomend it all be one piece so that you avoid ground loops and loose connections.

Q:I bought a Zmodo CCTV system.The system came with 60' of cable,so I purchased some 165' cables.I would like to have more,but I can't find anything longer than 165' anywhere.Is that the longest size that they manke?Thank you: Extend them yourself

Q:When I put the laptop into hibernation, the power pack still makes a considerable amount of noise. Since the memory was saved to the hard drive, is it okay to disconnect the power cable? Please note that the battery on the computer is pretty much dead and lasts for about 2 mins tops on normal mode: Yes, the battery wont eventually run out as other people have stated. Hibernation is similar to standby (low power mode that saves what you have running for resume) except it doesnt go into a low power mode. Hibernation saves to your hard drive and then the computer uses no power. Basically, YES you can unplug it and it will stay like that until you start it up again.

Q:I have an HP Pavilion ze5385us.... the power cable is messed up and I'd like to replace it, but the ones on the HP website are pretty expensive... I have a different computer so if I have to spend over 100 bucks then forget it. Does anyone know of a good generic brand?: dick smith or easily one of those kinds of digital shops they promote those packs with about 10 different adapters for $60 pay attention utilising some thing besides the indisputable fact that the right acer battery could void your assure

Q:Bought 60 Inch Full HD LED LCD Smart 3D TV by Sony while stationed in Germany. it came with a european a/c socket attached, so currently searching for an American socket replacement however I can't seem to find one with the same specs! Model is KDL60W850B: 1- if it is a DVB tv (german system), it will not work in the usausa system ATSC . 2- a power cable is determined by x volts y amperes for example 250v and 10a it means you can use it on 250v maximum .more voltage than that damages its insulation material and 10a current maximum more than that current causes the cable gets hot so risk of fire . 3- fortunately the power supply is SWITCHING MODE. so you can use it on 120v .

Q:or do I need to buy one?: No, the PS3 is a 3 prong outlet cable, and the PS2 is 2 prong. Also the end that plugs into the console is different for both. You can use a PC power cord for the PS3 if needed, the ends are the same.

Q:How do I connect this unit to my cd player? Splicing power cables? not too detailed in the manual.?: im sure it comes with a power harness(plug) you prob have to do some splicing just connect it t0 the same place where you get power for the cd player your probably going to get a wire harness for your cd player right? just match the wires from your cd to your ipod thingy before you solder or crimp your connections

Q:My ISP had installed an outdoor antenna from where a white RJ45 cable runs into a little white box (which is plugged into AC outlet) and from the same white box i do have another RJ45 jack plugged into my laptops NIC card. I came to know that the white ethernet cable is Power over Ethernet cable which carries the power as well as data. I just want to know if i can plug that ethernet directly into my laptops NIC card ? Can i do that will there be any harm to my laptop's NIC ??: Power Over Ethernet Laptop
