一、application scope
The cable is mainly used in digital switching equipment internal or short section of the connection between digital switching equipment, the highest 10 MHZ transmission frequency.Can also be used as an internal or and other digital devices between the short section of the connection.Can meet the digital switching system transmission of high bit rate digital signal.With smaller diameter, ease of installation and connection.
Product the YD/T 818-818 standard design and production.Its technical indicators fully meet the standard requirements.The structure stability of products reach the international similar products level.
二、cable type
Cable type by type and specification, it said the following:
HJVV
HJVVP
HPVV
HJCVV
三、cable construction
1, the conductor: the nominal diameter of 0.25 mm or Φ Φ single tin round copper wire 0.5 mm.
2, insulation: use PVC insulation, conductor chromatography using monochromatic or additive color ring.
Line 3, line to: to adopt the section from twisting synthesis of crosstalk in order to meet the strict requirements, and in accordance with the provisions of chromatography in order to easy to distinguish.
4, cable conductor: line to press with twisted into cable core type or unit type.Overlap with a layer of polyester film around the package.
5, block: cable can have cable shielding.According to user requirements cable can be blocked.Shielding have single plastic coated aluminum foil overlapping winding and shielding.Tin plating round copper wire textile block, or two methods at the same time use the shielding.
6, sheath: sheath for PVC plastic, color is gray.Or the color of the user requirements.

- Q: For example i have the Pelican xbox 360 av and power cables not the microsoft kind. So as i heard does it make a difference like does the intercooler still eventually melt in to your xbox 360 or will it stay normal? I ask this question because my niece also has an xbox 360 and while my 360 was getting repaired i came over to play her 360, when i plug in the intercooler it worked fine but i had a little trouble pulling the power brick cord out of the intercooler and hers is microsoft av and power cables, but when i pull my Pelican power brick cable out of my intercooler it came out easily, no trouble at all. So thats why i wanted to ask the question.
- its not going to melt your xbox 360. its why they made it to cool down the system. if someone told u it will is stupid.
- Q: I need a power cable for an XBox 360. where can i buy one?
- If it's the same as the power cable for an XBox, try Radio Shack. That's where I bought a replacement cord for mine.
- Q: ill exlplain more the battery is connected to one end of the fuse then i want to run 2 power cables out of the other end to both of the amps will tis work or will i just loose power the fuse is 60A if that helps. 60A is massive why a fuse that big is needed i dont no
- relatively there is alot incorrect alongside with your techniques. First. do not placed subs and substantial audio equipment in parallel with one yet another on an identical amp. One set is low freq and the different is higer. you are able to desire to seperate them. Get yet another amp for the 2nd set of audio equipment. additionally, switching the audio equipment out and in could chage the load the amp sees. solid thank you to screw some thing up with a change turning them on and rancid. purely get 2 amps and function one for substantial and one for subs. additionally, make helpful the turn on twine is on change voltage. you have it setup to consistently be on and which will run your battery ineffective. additionally, do not twine speaker on your radio/cd participant and additionally to the amp. you will fry the setup quickly!
- Q: Hi, Recently I bought nikon S550 digi camera from U.S, their power supply is different from India. In the power cable they mentioned 125 7A, do i need any convertor or directly i can use.
- India power outlets run 220v, not 120, so you are going to need a converter or a completely new power-supply.
- Q: need to buy for sharp aquas 52 inch flat screen
- It's a universal AC power cord. The same one you would use for most other flat panels, desktop pcs, and the PS3. Go to your local Best Buy. They have them in 2 places: Playstation 3 accessories or the PC cable isle in Computers. $10 give or take a couple bucks.
- Q: I am looking to replace a broken power cable for my DigiTech RP1000 guitar effects board, but I am curious as to whether I need to find a cable specifically for this device, or if I can look up any cable with an output of 9V AC; 1.3 Amps.
- Hi at such low current and voltage it really doesn't matter that much.
- Q: The power cable troughs are divided once and twice
- Can be used for overhead, buried and pipeline laying of the cable line
- Q: I left my power cable at my cabin, which is a few hours away. I don't want to replace the cable (I'll be going back anyway in a few days), but I need to use my laptop. So far I've tried an old laptop cable, but its to big, and a game system adapter, but it doesn't have enough power. Are there any solutions that don't involve me buying a new cable?
- Do NOT play guessing games with this. If you use one of a higher rating or worse with reverse polarity input you will totally destroy the laptop.
- Q: I want to hook up (charge) my iphone AND my radar on my motorcycle. My radar is already wired to the 12v cable in my bike. Now can I hook up the iphone to the same cable? or is it gonna be drawing too much power? thxI was planning on buying the cigarrete lighter thing, and pluging the iphone into that. I'd obviously hook up the cig lighter to the 12v cable.
- Should be ok. The current draw of these gadgets would be minimal,I would guess 5A tops
- Q: The power supply I have has 8 Peripheral cables. I need just a few more than that. Is there a cable splitter I can get? Or what can I do? I have the power, just need the extra connectors.
- Yeah, okorder /
