Are transmission power cables capacity designed by voltage or by power is there any limit to the voltage that can pass?
Transmission power cables are designed by current carrying capacity.
How do you calculate weight of PVC insulation on cables?
By multiply current supply and voltage
The high-voltage section of a unit substation contains devices called to which the incoming high-voltage cables are terminated?
potheads
When splicing high voltage cables what is the minimum distance between splices?
30 cm
Single core cables benefits?
One of the single core cables benefits is high current rating. The other benefit is that the operating temperatures of single core cables are least affected by the other cables.
What is the voltage used in submarine cable?
Submarine power cables work on voltages of 400 kV or more, often with DC because they are linking power grids that are not synchronised.Submarine communications cables now work with fibre-optics so the signals are modulated light-waves.Additional AnswerFurther to the original answer, another reason for using direct current for submarine cables is to eliminate capacitive currents that would flow if a.c. were used instead. The closeness of the submarine-cable's cores results in relatively-high levels of capacitance between each core and, with a.c., this would represent a capacitive load resulting in a continuous capacitive current along the cable. Such currents flow in all underground a.c. cables but, due to the length of most submarine cables, the capacitive current can be unnecessarily high.

Where can one purchase optical digital cables?
There are many websites and companies that offer optical digital cables for sale. Some of these companies that offer the cables are Amazon, ZORO Tools and Walmart.
What is a optical?
An optical microscope is what is commonly known as compound microscope.
Submarine cables connecting Pakistan and Dubai?
yes
What are the different types of audio cables and how do they differ?
There are speaker cables, unbalanced analog cables, balanced analog cables, coaxial digital audio cables and optical audio cables.
Is it possible to have electrical voltage exist but no electric current exist?
Yes. For example, a car battery always has a voltage of 12V (unless it gets completely unloaded, of course), between its terminals. But a current will only flow if cables are connected.
What are or relay circuits used for?
A relay is used to switch a different voltage and/or current, to the control signal.Examples:1) Low voltage electronic signals operate a relay, which can then control mains voltages and high currents. This isolates potential harmful voltages from getting into the low voltage electronics.2) The control switch may be some distance from a high power unit. Instead of running large cables and using large clumsy switches to control it, small low voltage, low current cables, can be used instead. Using a relay close to the unit to keep the price down and danger away from the operator.3) The starter motor on a vehicle, uses massive amounts of current and have thick cables to supply it. These large cables are not routed through to the ignition switch. Instead, small cables are used at low current, to operate a solenoid right at the motor. This is a relay.
Is the submarine cable is suitable for under water?
Submarine cables are only suitable for use under water, that is what they are made for.
