What carries messages by wire across the sea?
Submarine communication cables, also known as undersea cables, carry messages by wire across the sea. These cables are laid on the ocean floor and transmit data through optical fibers.
What is the maximum operating temperature conductors?
The maximum operating temperature for conductors is typically around 90°C for most common types of wires. However, there are specialized conductors and cables that can handle higher temperatures, such as those with insulation rated for 105°C, 125°C, or even 150°C. It is important to choose a conductor with a temperature rating suitable for the specific application to prevent overheating and potential fire hazards.
How many T-9 cables does it take to supply a ship with 1600 amps?
To determine how many cables are needed, we need to know the maximum allowable amperage each T-9 cable can handle. Once we have this information, we can divide the total amperage needed (1600A) by the maximum allowable amperage of the T-9 cable to find out how many cables are required to supply the ship with 1600 amps.
What is the temperature rating of thhn?
THHN wire is moisture resistant thermoplastic allowed for use in dry and wet locations. Maximum temperature is 60 C or 140 F. Being thermoplastic it should not be handled below 0 C as cracking of the insulation could easily occur.
What is the max data capacity of STP?
STP (Shielded Twisted Pair) cables can support data capacities ranging from 1 to 10 Gbps, depending on the category of the cable. The maximum data capacity of STP is typically lower compared to UTP (Unshielded Twisted Pair) cables due to the additional shield that can cause some signal attenuation.

Submarine cables connecting Pakistan and Dubai?
yes
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.

Disadvantages and advantages of submarine cables?
A. you can go under water. D. if they break you die.
What is a cable ship?
A cable ship is a vessel fitted for laying and repairing submarine cables.
What is submarine cable?
Cable designed to be placed underwater. Such cables must be specially protected against moisture. At shallow depths on continental shelves, submarine cables commonly are plowed in and armored to protect them against ship anchors, trawler nets, and sharks, which are attracted to the electromagnetic fields and like to gnaw on the cables and repeaters.
Is this statement true or false Submarine communication cables connect the continents to provide communication through the use of fiber optic technology.?
true A+
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 minimum value of Ir test in 11kv cables?
4444
What is the minimum category of cable that is required to obtain speed of 10 mpbs?
Category 3 LAN Cables, maximum speed is 10 Mbps. It can be used for telephones as well, option for Ethernet in years past.
