What else can I help you with?
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.
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.
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.
Which kind of cable are used in hvdc transmission system?
In HVDC (High Voltage Direct Current) transmission systems, the primary types of cables used are underground cables and submarine cables. These cables are typically made from materials like cross-linked polyethylene (XLPE) or oil-filled cables, designed to withstand high voltage and environmental conditions. They are insulated to prevent electrical leakage and ensure safe transmission over long distances. Additionally, the use of bipolar cables allows for efficient transmission and improved reliability in the system.
How do you calculate weight of PVC insulation on cables?
By multiply current supply and voltage

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
Are optical and spdif cables the same?
No, optical cables use light to transmit audio signals, while S/PDIF cables use electrical signals. Optical cables are most commonly used with devices like home theater systems, whereas S/PDIF cables are found on a variety of audio equipment like TVs and CD players.
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.
