Product Description:

The PVC insulated power cable and fire resistant cable are suitable for fixed laying in power transmission and distribution lines with A.C.50HZ and voltage of up to and including 6KV.

1.Performance Characteristics:

  1. the long-period allowable operation temperature of conductor shall not be higher than 70℃.

  2. Conductor maximun short circuit(not more than 5 seconds)temperature shall not be higher than 160℃.

  3. The cable is not limited by drop in level when being laid, and the environment temperature shall not be more than 0℃.

  4. Perfect cheminal stability, resistant against acids, alkalis, grease and organic solvents, and falme retardance.

  5. Light weight, perfect bending properties, installed and maintained easily and conveniently.

Voltage rating: 0.6/KV、3.6/6KV.
Conductors: copper or aluminum.
Number of cable cores: one core (single core), two cores (double cores), three cores, four cores (Fore Equal-section-area cores or three equal-section-area cores and one smaller section area neutral core), five cores (Five equal- section-area cores or three equal-section-area cores and two smaller section area neutral core), we provide armoured type for the cables stated above.
Outer sheath: PVC or PE
Our company has been carrying out chinese national standard GB12706 and GB12666.6 (equivalent to IEC60502 and IEC60331) for PVC insulated power cable and fire resistant cable needed by domestic customer, and for foreigner customers we can manufacture in  accordance with BS, DIN and other countries” standard. In addition, we can design and manufature PVC insulated power cable with special characterics according to needs of customers.

Note:Pw-Coefficient of thermal resistance of soil when no water move.
      The continuous current capacity of(3+1)-cord,(3+2)-core and five-core cables can be selected according to than of three-cores cables.
      Pw-Coefficient of thermal resistance of soil when no water move makes soil dry.
      *-The surface temperature of cables is not above 50℃,no water move.

Q:Replacement Power Cable for HF M300?
The power adapter that came in the box is Canon's CA-570. Search for that at OKorder.
Q:What is the difference between KVV and VV cables and are they clearly different?
Is there a problem driver in Device Manager? Should be driven by the problem
Q:What is a good place 2 run the power cable from my amp?
run it under the car
Q:PVC pipe line 6 points and 4 points which big ah?
Look at the chassis of the internal power supply is not connected to your power interface to see how many mouth ~ there is a 4-port square of the additional power socket to see there is no link that is what the link method is generally written on the motherboard ~ The word is a small look carefully ~ Corresponding to the chassis of the various plugs to see if there is no wrong plug (but the general can not start too much Gibel error) can be observed by the power indicator light (light) and observe the hard disk indicator Red (flashing) to determine the right or wrong line. There is only listen to the warning sound, the boot will be crisp ring, if there is proof of plug, there is no relationship in fact because there is no alarm, hdd hard drive, led + - white green two-wire power instructions, the above said three lines Do not plug can also be a normal boot, as long as it pw power plug can be a ~ rw restart does not affect the boot
Q:Do most computer MB does not contain a power supply connector for a SATA power cable coming from the SATA HD?
ur mainboard is only ide compatible then, u can add a sata pci card tho so as to add sata drives !!! :)
Q:Locating damage to lighting power cable?
I usually have one of my kids lick their finger and run it along the cable. a lightbulb in the mouth helps.
Q:What is the wiring principle in the home improvement circuit?
This is not the end of the family with a good audio and video lines are thousands of dollars I do not know what kind of advice you want to go to the local workers Duan Gengmang Gama moths tied to the supermarket stall can find!
Q:I just bought a 47inch LCD 1080p flat panel T.V. I bought nothing extra for it what else do i need?
i jus bought a 37inch =P wat u need depends on what u want. but u shud get a power strip surge protector!!!
Q:my PSU doesnt have a 4 pin power cable!!!?
Just replace the power supply. What's the problem? You have an OLD ATX powersupply with 20-pins. The NEWER ATX power supply is 20+4 pins. --- Kasey C, PC guru since Apple II days Make it idiot proof and someone will make a better idiot.
Q:What does an OEM hard drive require to use? power cables, controller cards, etc.?
just the data and power cable and if your mobo doesnt support that type of drive (like if it only has ide and you want sata) then you will need a controller card
