Specifications

xlpe insulated high voltage power cable
1.CU or AL conductor
2.xlpe insulated
3.more than 25years' production experience

1.The standards

The power cable is mainly complying with IEC 60502 standard, also can be produced according to OEM requirements and other standards, such as BS, DIN, ASTM, VDE, NFC standards, and so on.

2.the construction of the power cable for different voltage grade

2.1 low voltage cable power cable

Low voltage (0.6/1 kv)

single core or multi-core

copper or aluminium conductor

pvc inusulation

steel tape armored or galvanized steel wire armored or unarmored

pvc outer sheath

power cable.

2.2 medium voltage cabel power cable

Voltage grade is up to 35kv,

cross-section area can be up to 1000 sqmm (copper or aluminiun conductor).

Conductor long-time operating temperature is 90 degrees.

In short circuit, conductor highest temperature should be not more than 250 degrees.

1kv-35 kv

multi-cores

copper or aluminium conductor

xlpe insulation

copper tape or copper wire screen

galvanized steel wire armored

pvc or pe sheath

power cable

2.3 high voltage cable power cable

High voltage (35kv~220kv)

copper or aluminium conductor

xlpe insulation

metal sheath (lead or corrugated aluminium)

hdpe or pvc outer sheath power cable.

Laying conditions: for lyaing under ground with large different altitude, be able to bear external machanical force and moderate pulling force.

3. the power cable's characteristic:

3.1 long time operating temperature for cable conductor is 90 degrees.

3.2 the highest temperature of the conductor in short circuit (no longer than 5 seconds) in not more than 250 degrees,

if a joint is in the cable, the temperature of the tinning welding joint is not more than 120 degrees, compressing joint not more than 150 degrees and electro-welding joint not more than 250 degrees.

3.3 no drop in limited provided there is full mechanical tention when cable is laid. It si forbidden to lay cable in iron-pipe or to fix cable by circling around the cable with iron materials.

3.4 being laid, the minimum temperature of the cable shall not be lower than zero degree. In the case of lower temperature, heating measures shall be taken.

We can also supply the OEM and customized products according to your request

Q: NH-YJV-4 * 4 in NH-YJV-4 * 4 in power cable tube: Because the AC operation will produce eddy current, will make the steel pipe and cable heat burned. Single core refers to only one conductor in an insulating layer. When the voltage exceeds 35kV, most of the single-core cable, its core and metal shield layer relationship can be seen as a transformer primary winding coil and the relationship between the core. When the single-core cable core through the current when there will be magnetic lines linked to aluminum or metal shielding layer, so that both ends of the induced voltage. Power safety regulations: 35kV and below the voltage level of the cable are used at both ends of the grounding method, which is because most of these cables are three-core cable, in normal operation, the current flow through the three core sum of zero, in the aluminum There is no flux chain outside the package or metal shield, so that there is essentially no induced voltage at both ends of the aluminum or metal shield, so there is no induced current flowing through the aluminum or metal shield after grounding at both ends. But when the voltage exceeds 35kV, most of the single-core cable, its core and metal shield layer relationship can be seen as a transformer primary winding coil and the relationship between the core. When the single-core cable core through the current when there will be magnetic lines linked to aluminum or metal shielding layer, so that both ends of the induced voltage.

Q: I need a 3.5mm 5V DC power cable with a USB input. I do not want to order one online. What store would sell this? I already went to Best Buy and Radioshack.: Sorry okorder / You will be fine and wont be scammed. OKorder is a possibility but its a tad sketchy but its easy to use and not get again scammed but its your choice ofc i don't know the situation your in. im just guessing your worried about ordering online due to scamm websites, it could be that you simply don't have a card that can shop online (or even a card). Also delivery should be fairly quick (most being a week) so you won't be waiting too long either way. Turtle beach is based online, and distribute mainly from their website,(such is most designer accessories) the only reason they have their products in stores are because of their success online, and were able to expand but even then they only ever sell a few of their headsets in stores never their full range, then expecting parts is very rare. p.s i realise its a generic piece of equipment but its quite specific and there are very few things that use somthing that you've specified (not the sized and volt just a DC power cable that has a USB input) , that includes headsets, seriously most headsets don't require a power cable (and it having a power cable doesn't make it good) Hope this helps :S

Q: I have my old 350 power supply cable but i got a new 520 one. do i have to use the defuly 520 power suppl cable? i use my old cabbke: No, as long as it can supply the proper voltage and amperage.

Q: should you run RCA cables and power next to each other?: as long as either one is shielded or insulated.

Q: This is a clock/phone I was using as a kid. Found it in my basement, and I would like to use it now. I no longer have the original power cable, that's the one needed for the left side. They both look similar, but are not the same. The right side is for the telephone cable. I have no idea what the left's called or where to buy it? I'd appreciate some help if anyone knows what its called, Thanks.: Give them a try. This isn't a common power cord that can be purchased locally. However you may find a used one on OKorder. You can do an OKorder search using the model number of the unit.

Q: I'm AM NOT looking for Ipod, USB, ethernet, or cellphone charger cables, just simple 120V appliance power cables that can be hardwired/soldered in to replace existing cords.: HERE. okorder

Q: I would like to buy a replacement. What AC/DC adaptor should I buy? Should I buy the exact same model (FSP150-AAA)? I assume any AC/DC adaptor that has the same spec is ok but I am not sure what is the key for the spec. Any advice would be appreciated.: There appear to be various manufacturers of FSP150-AAA power supplies. You must have a substantial laptop or whatever that is powering. Most laptops have 65 to 90 watt PSU, my gaming laptop is 120 watt, and FSP150-AAA is 150 watt. Or is that an all-in-one PC where the computer is built into a screen? The one you link to is one of the ones I found in a web search.

Q: recently i purchased an imac G4, it included everything)keyboard,speakers,mouse ect.) but, it didnt come with a powercable. i knew this when i bought it, but thought it was a standard connector,i was wrong, it is a 3 pronged connector, I have a cable that will fit, but it is only 2 prongs, (it's missing the ground pin) . i only can return this item in 4 days if there is a problem with it, i could buy a powercord, but i risk it not coming in time. Can i use my 2-pronged power cord just to test it's funcionality. (fans,chime etc.) without the computer catching on fire of any other type of failure.Chris: specific. the means cords designed for the iMac are what's mandatory to function the iMac. the present twine probably isn't feeding adequate means to function all stages of the device. that could happen. substitute the twine. optimistically, which will remedy your subject. stable success.

Q: what size of main power cable to use for two amps with combined power of 600 watts rms.the length of the run will be about 12 feet from battery to amplifiers.: use a 4 Gage, always reliable and always dependable. Its a bit larger but you will have no problems
