Product Introduction:Optical Fiber Composite Overhead Ground Wire
The product according to optical fiber composite overhead ground wire (OPGW) power industry standard DL / T 832-2003 "optical fiber composite overhead ground wire" or domestic machinery industry JB / T 8999-1999 "OPGW" industry standard. Reference standards are mainly IEC 60794-4-1 "for cable high-voltage overhead power lines" and IEEE std 1138 "for utility power line optical fiber composite overhead ground wire."
OPGW cable is a special fiber optic cable, fiber optic cable and ground it sets in one, both to meet the requirements of optical communications, but also to meet the mechanical and electrical properties of the ground power system.

Product features
(1)Rated voltage: No
(2)When the cable laying temperature: should not be less than -20 ℃
(3)OPGW cable connection: connecting basic method of OPGW cable connecting with ordinary and more stringent requirements.
(4)Installation Requirements: To prevent vandalism, cable connector box must be installed in more than 6 m from the ground position, and because of the special nature of OPGW cable is required to reserve more than cable.
Product advantages and disadvantages:
a.cable diameter is small, light weight, small short-circuit current capacity
b. light units form a suitable fiber excess length
c.anti-stretch, anti-torsion, lateral pressure performance slightly worse
B.Stranded stainless steel tube OPGW
- Q:cable laid in the GI trays and temperature is 30 digree centigrade
- There is no definite safe formulas for your cables because it depends on many factors like what conductor . what insulation, how many cores ,what is your load , where is your load and ambient temperature and so on. The best guidance will be from the particular manufacturer who would provide the tables under various conditions as above.
- Q:I have a Technics SL-D20 Turntable recently purchased from a garage sale that lacks a power cable. The turntable has a 2 prong adapter, but it is not one that has a square and semi-circular portion, but rather seems to accept an elliptical two pronged cable. It is listed on the back as Power Source AC120V 50 or 60hZ 6wThank you
- Man that could be tough. It sounds like a belt drive turntable, I'm sure of the name of the part, but it's basically there to move the belt; it isn't metal so it isolates the belt, thus reducing vibration and transmission of motor noise. That's what I think it is anyway. I'll bet if you go on some audiophile web sites, you can find a parts listing for that model, and get a name and part number. Technics were very popular, I've got a belt drive one myself that I haven't hooked up in 10 years.
- Q:The question above relates with the Transpose Line.One of the subtopics under Transmission Line Parameters in Power System.
- If the adjacent line induces current in a nearby cable that would be a problem. Transposing results in one section having an induced current with a certain phase but the next section (after the transposition) has an induced current with the opposite phase. Over the length off the cable, the opposing induced currents will cancel each other out.
- Q:what kind of power supply cable plugs into the hard drive?
- they are called molex connectors, for optical and hard drives, berg connector for floppy drive
- Q:Hello, i have a quick question, this card doesn't need PCI cables right?My power supply is 450 wattNVIDIA GTX 750 TI is the cardThank you
- it depends on which 750ti you buy some dont need power some do but if you have a 450w psu then you should have a 6pin pcie on it anyway
- Q:I have a Benq scanner 5000 and have lost its power cable.Please tell me what adapter to buy! input = 220v
- here okorder /
- Q:i have a SATA hard disk and i connected it with a sata power cable and recently i bought a sata optical drive and i have no power cable for connecting the drive, so i decided to connect it with the power cable of hard disk(I have two sata hard disk)
- while you're meaning are you able to boot off of the IDE annoying force and get entry to the Sata force, the respond is sure. in basic terms connect the SATA annoying force, and make beneficial the BIOS settings are set to boot from the IDE force.
- Q:my amplifier s power cable is not long enough to reach battery . so is there any problem if i take another piece of power cable and then attach them ?
- If okorder /
- Q:Hi, just moved to Finland from US. Will my x box 360 works with a new powell cable? Or do I need something else besides that. And where should I get it from in Turku or Helsinki. Thank you!
- Go back to US
- Q:Does anyone know if there are adapters to convert an extra PCI Express power cable to a 4-pin molex power cable? My Power supply has 3 PCI Express power cables and I only need to use one of them, but I could use the extra power cables.
- Sorry, there are no such adaptors to convert a PCI-E cable to a molex.
