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 Cord Laptop Cable Exposed. Dangerous?
very dangerous
Q:What is the max distance to pulling 220 or 380 KV cables without loss of power?
For zero voltage drop, the distance is zero. If this is a practical question, you would need to know: 1. How much voltage drop can be tolerated (eg. 1%? 5%? other?) 2. What is the maximum current the cables will need to handle? 3. What is the resistance-per-length of the cable?
Q:Why won't my cable box power on?
If your not getting any power to the box no little green lite or humming noise coming from the box then its dead. your just going to need to get the box replaced you should be able to just bring your box in and trade it out to avoid a service call charge.
Q:What is the difference between KVV and VV cables and are they clearly different?
Eight or six no less, the first good fire retardant pipe on the line, the box can be opened after the slot
Q:can you use power cable as your ground cable on your amp?
Ground Cable
Q:Do RCA Cables supply power?
I have not seen or read from any source that RCA cable can be used for power. It is designed for audio connection and video connection only. The wire are not designed for use with electrical power connection, it will over heat and the wires will melt. Hope this will help you out.
Q:Why my home analog TV connected to the digital TV set-top box after the screen is black and white
The middle is to connect the two cables together, the terminal is connected to the equipment
Q:Having another set of Xbox 360 power and video cables?
it might work, and the elite is black, so u have either the arcade or pro
Q:How much power can I draw from the 12v on the Xbox 360 DVD power cable?
its not smart to attach anything to your 12v power on the dvd line it can cause problems to your 360 and your dvd drive. get your 12v directly from the power socket .
Q:Help Running Power, Phone, Network, and Cable Line to my Shed!?
Congratulations on finishing your shed. Unfortunately, you can't run your communications wiring in the same conduit as a power line. It's against code and it will mess with your low-voltage signals. You'll need to run a separate piece for those. Keep it one foot away from the power conduit, crossing at right angles. Of course, you can run them closer for short distances, but keep it to a minimum. Bear in mind that no matter which satellite cable you choose, it won't like sharp turns. Running shielded cable for the network is a great idea. Also, network cable is getting better every day, run the most highly rated you can afford and you won't regret it. I would not recommend looking for any all-in-one cable. They often are not as well designed as the individual ones. Personally, I would run extra lines now, for future expansion. Hope this helps.
