Product properties:
1. The long-term working temperature allowed by overhead conducting wires is 70°C;
2. When there are large-span rare weather conditions and there is less ice coating occurring in heavy ice areas, maximum stress the lowest point of the conductor sag should not be more than 60% of instantaneous destructive power;
3. When the wires are connected, strands around the connecting pipe should not bulge, otherwise the strands of wires in operation will be unevenly stressed, after the joints are pressed, outlets of connecting pipe should be covered with moisture-proof paint to prevent corrosion;
4. When the wires are installed, sag stress of all the wires at the same gear should be the same, and within the range permitted by the limited distances to the ground and exceeding the distance for protection of building, the conducting wire stress can be higher by 10-15% than normal tension. Scope of application: This product is applied to overhead power transmission and distribution lines.

- 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
- That type of connector was common before the IEC style cable became the standard. Perhaps you can scrounge some more tag sales or estate sales, friends garages and attics. You might check to see if there is an electronics surplus store in your town. Those guys never throw anything away.
- Q:do i fit the 2 other power connectors to the psu wire or just the one connectorThanksCard is an hd3870
- I have the HD 3870 and I do not recall it having 3 power connectors. There is only one, which is the 6pin. Only the 3870X2 and the 2900 have two power connectors which are 6pin and 8pin. Read the manual. You might be looking at jumpers or sound connectors and putting power to those items will cause you to fry your good card.
- Q:(for example : 1sqmm, 4sqmm, 35 sqmm) i need a formula to calculate current by knowing the area of the cable?
- Hi Sherlock, You need a copy of BS 7671 The IEE Regulations. By the cable sizes mentioned you must be in the UK. The current carrying capacity of a conductor is a function of its Cross Sectional Area, Length, Method of installation, Is it grouped with other circuits, Ambient Temperature and fuse or CB type. (these are called multipliers) For larger cables the power factor of the load must also be considered. The basic formula assuming no multipliers are used is Volt Drop per ampere per metre X length of run X Design current / 1000 Volt drop is from the tables in BS 7671 Length of run is the cable length design current is the current the cable will have to carry in normal use 1000 is because Vont Drop per Amper per Metre is given in millivolts
- Q:so I bought a new power supply to go with my new case and motherboard, and when I recived the new power supply it didn't have a power cable That Plugs into the wall, can I use the one from my old power supply or will I have to get a new one? Cause I tried using it and my pc didn't turn on, or is my power supply that I got possibly dead?
- every power supply I've gotten for years uses completely standard, detachable power cords. I've never yet seen one that will not use the same cords as all the others. Use the one from the old supply
- Q:my laptop keeep on saying installing lite on camera crystal eye and it and put implug power cable and i dontt no what one is so what is a power cable pleasssse help ?
- A power cable is an assembly of two or more electrical conductors, usually held together with an overall sheath. The assembly is used for transmission of electrical power. Power cables may be installed as permanent wiring within buildings, buried in the ground, run overhead, or exposed.
- Q:Hello guyzz, recently i have bought new card powercolor radeon hd 6770 1gb gddr5 .i installed it but it required a 6 pin power cable forbut i checked in my all pc..i cant fine any 6 pin power cable.so without any cable its not working wat i do plzzz help.......
- There okorder /... 2. Buy new Power Supply at least 450 Watt. ( I suggest it because that graphics card requires a strong source of power) * if your Power Supply is powerful, sufficient only buy VGA Power Adapter ~hope it help~
- Q:The hdd i am looking at is OEM nearly everywhere so i'm wondering what i would need to use it.
- Any OEM challenging rigidity i've got ordered has no longer incorporate cables (they got here with the motherboard). do no longer comprehend the place you're ordering from although - ought to be distinctive. i'm getting all of my stuff from Newegg. and that's the place i could propose you %. some up in case you like them. continuously stable fees.
- Q:I have a Dell Optiplex 790 SFF, I need a replacement power cable, on the manual it says for power: 240W, 1259 Btu/hr, 100 Vac to 240 vac, 50hz to 60 hz 3.6A. I contacted Dell and they said they have a power cable for it, the Dell 5120P cable which is 125 V 10A. Now my concern is with the 10A vs the 3.6A listed on the manual, should I be concerned?
- no it will be fine, the maximum power needed as you state is 240W the replacement power cable is 125V 10A=1.25Kw so the power cable is grossly overated HTH David
- Q:I need a power cable for an XBox 360. where can i buy one?
- Best Buy, EB Games (possibly), Future Shop, Circuit City.
- Q:Apparently my computer has a 300 watt power supply. I am wanting to purchase a new graphics card but apparently in order to get a better graphics card then my existing card, Geforce 8400, I need a larger power supply.What will I need to purchase to increase the power supply to 500 watt and is it really worth buying all this? I am thinking I might aswell save up a bit more and buy a new computer.Any help apprietiated, thank you.
- Replacing okorder /... That link sorts the power supplies (ones in the 500 to 600 Watt range) by customer rating. DON'T cheap out on a power supply, you will only have headaches down the road. Stay away from companies like Rosewil and HEC for power supplies. I love the Antec brand, been using them in my PC builds forever (15+ years). Also, look for ones with a 120mm fan, they are a lot quieter. One note.... some computer manufacturers use a non-standard power supply, and you cannot retro-fit a standard ATX style power supply in their case. I have an old Dell that uses a really long and slim power supply that sits at the bottom of the case, and I am stuck with it unless I buy an upgrade from Dell (which aint gonna happen).
