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.
What is the advantage of leaving some slack when installing electrical cables?
Number of reasons: * Provides room for expansion when the building heats up. * Allows slack to move wires when remodeling. * Allows slack to reconnect wires when redoing terminations.
Can Aluminum mylar-tape-shielded cables be used instead of Copper braid-shielded cables for instrumentation cables?
Actually, aluminum mylar tape shielded cables are better than copper braid shielded cables for instrumentation cables.
Are power cable armour to be earthed at both ends or at one end only?
One end only. Single point grounding is a rule of thumb. The reason for this is when you run cables together, including a shield or ground cable, the cables with power flowing in them will induce a voltage on the other cables. If two grounds are placed on a shield or ground cable, unwanted current will flow in a loop through the cable.

How do you reset computer after installing oxygen sensor in 2003 Trailblazer?
remove negative and positive cables from battery, touch cables together for 30 seconds and then reconnect.....will be reset.
Which security cables have the highest rates of customer satisfaction (and/or best Consumer Reports reviews)?
Epson security cables are the best.
What happens when you reduce current in the cables?
you lose chanels
Do parallel cables of the same length carry the same current?
yes in case the two cables have same resistance
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 difference between cat5 and cat6 cables?
CAT 5 cables are recommended for Ethernet connections up to 100 mbit. CAT6 are approved for 1000 Mbit (gigabit) Ethernet. If you are installing cables for a network these days, choose CAT6 to ensure future compatibility.
