Q:is 400V submarine power cable available?
The power cables should be stored on the submarine by the Electrician Mates as ours were on a destroyer. 60KW is not that much power and one three phase cable can handle it.
Q:1.2 meters below the road can use pvc tube wear armor cable?
Have to fight trumpet, mainly to protect the cable jacket is not scratched
Q:what is the resistance of overhead power cables?
electrical resistance? depends on length, temperature end diameter mechanical...depends on material, steel, copper, aluminium... resistance to corrosion, to fatigue due to vibration from the wind... be more specific Guru
Q:What is that black box on power cables?
its a transformer to cut the mains plug voltage down to the same voltage as the battery which will be around 16volts to 20 volts for a laptop,the desktop PC will have the same transformer built into the tower casing beside the fan,but you just cannot see it, and there will be a voltage selector switch for the country you are using it in ie-UK =220-240volts, USA=110 volts or similar,both the laptops and desktops use the same internal operating low voltages,and mains voltage would fry everything inside ,that's why they are fitted with the transformers.
Q:Water and electricity installation drawings in the kz on behalf of what material of the threading tube
Color line, HDMI cable, S-terminal line of the three transmission video signal (HDMI can also transmit audio signal); coaxial line is the transmission of audio signals
Q:Can a kink in the power or rca cables make my subwoofer not work?
Any thing is possible. You can have a break in the wire (any where). But normally the kink won't do anything (good or bad). Good luck........
Q:Amplifier power cable?
Kicker,Tsunami,Memphis, or KnuConceptz. U can get away with 8awg but thats a nice car and u dont want to risk fryin anything so stick with 4awg I really dont recommend 8awg in ANY setup just dont like it, 4awg is perfect and gives u headroom as well, and 0awg wuld be overkill.
Q:cable splitter power pass?
It means it can pass DC current, such as used for satellite LNBs and amplified antennas
Q:Will PS2 controllers and power cables work on a PS3?
Controllers, yes, you just need a special adapter. Power cable, absolutely not, since the PS3 Fat uses a 3-prong power cable like what computers use and the PS2 uses a completely different kind with only 2.
Q:Where can I find a 4 Pin Fan Power Splitter Cable in hamilton Ontario?
Before hooking that up, check the specs on your motherboard to see if that fan header will support loads from both fans. You may need to get a Molex to 4-pin converter and power directly off your power supply.
