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:Power cable YJV22-8.7 / 15kv-3 * 300 what meaning
(Including the insulation layer) of the total area should not be greater than 40% of the internal cross-section; . the tube wire is not allowed to have joints and twist the phenomenon; . the same loop of the phase of the wire, Regardless of the number of roots should be penetrated into a tube, and different circuits and different voltage lines are not allowed to wear a tube, AC and DC line wires shall not wear a tube, a phase line are not allowed to penetrate alone Steel Pipe. If the requirements are not strict, the power cable, the control cable can wear the same tube; but the signal line will be discretionary, although the signal line is shielded cable, but in order to maximize the signal transmission quality, and other signal lines are generally layout. UPVC plastic pipe with excellent insulation, acid, corrosion resistance, many chemical plants used as infusion piping. The other is also used for sinking engineering, medicine piping works, mineral salt water piping works, electrical piping works. Also widely used as a telecommunications cable. So it can be UPVC pipe to do electrical piping. As for the galvanized steel pipe is not necessary. If the power cable and signal cable at the same time with UPVC pipe laying, were classified separately perforated, the best interval between the two 20cm to prevent interference, with galvanized steel pipe pipe is not necessary so care.
Q:Power cable through a 2003 civic?
yes okorder.com/
Q:Cant find a spot for power cable! :(?
I've gone through the door with 6 gauge wire, I wouldn't recommend this at all, but especially with anything larger than 6 gauge. It didn't really let any water in at all, but I must have gotten lucky, I've heard a bunch of horror stories with that. I'd say just look harder or if absolutely necessary, go through the floor, but make sure to seal it up good. Note: I was running a 450 watt amp at the time I had the 6 gauge wire, now I've got a 1000 watt mono amp with 0 gauge wire running through the firewall :-)
Q:Power supply missing cables?
Handycam Camcorders do no longer draw potential from USB. you may desire to purchase a replace potential grant cable. while you're taking the camcorder to a place like superb purchase or Radio Shack, you may in all likelihood get a clean cable for little or no money (regardless of if that's not the best Sony cable).
Q:what are to 4 connectors on the power cable?
The four pin connector that is used to power PC drives supplies two different voltages: +12 volts for the motor +5 volts for the electonics The other two pins are ground pins. ________ / .............. |..1..2..3..4..| |.................| Pin Function 1 +5 V 2 Ground 3 Ground 4 +12 V
Q:can you hook up 2 power cables to one battery?
That's not massive power being took out of your battery. If you have one 4 gauge with a distributor block (splitter) running to more 4 gauge. It'll still only get the power of one 4 gauge. But if you wire two 4 gauges up to the battery then both wires are gonna get their power and suck out alot of power. Update to the Big 3 and be safe.
Q:do i need a phantom powered cable?
Yes, you will need phantom power for this mic since it is a condenser mic. What is phantom power? Condenser microphones use an active coil around the diaphragm. This coil needs to be energized in order for the microphone to function. Phantom power is a low amperage, 48 volt signal that is sent to the microphone in order to energize this coil so that the microphone can operate. Phantom power doesn't require a special cable. The signal is sent through a standard XLR cable. But whatever interface you are using to connect the microphone to your computer will need to be able to produce the phantom power to run the mic. It's usually nothing more than a switch or a buttom to turn the phantom power off and on.
Q:Where can I find a power cable for the eMachines monitor .. model 900W?
try radio shack.
Q:Will Dish washing liquid soap damage Romex power cables?
No, it should be just fine.
Q:How do I find the direct power cable on a 1988 chevy k1500?
The direct power cable runs from the battery to an access point usually on the drivers side fender well. There is also sometimes a shielded stud on the firewall near the center of the truck. Failing to find either of these, a connection to the battery positive terminal will work just as well
