Shows what is inside!

From the National Oceanic and Atmospheric Administration on Submarine Cable:

It is a common misconception that most global communication is accomplished via satellite. In fact, over 95 percent of international data and voice transfers are currently routed through the many fiber optic cables that crisscross the world’s seafloors. See U.N. Env’t Programme World Conserv’n Monitoring Ctr., Submarine Cables and the Oceans: Connecting the World, at 3, UNEP-WCMC Biodiversity Series No. 31 (2009) [hereinafter “UNEP Report”].  The earliest submarine cables carried telegraphic traffic.  The first successful trans-Atlantic submarine cable – a simple copper wire – became operational in 1866, delivering about 12 telegraphed words per minute.   As technology and laying techniques improved, the submarine network expanded greatly. 

September 1956

In September 1956, the era of submarine coaxial telephone communication began when two coaxial cables capable of carrying multiple voice channels came into service linking London and North America.  Finally, in 1988, the first transoceanic fiber-optic cable was installed linking the U.S., the U.K, and France.  Thereafter, the number of submarine fiber-option cables proliferated as they rapidly outperformed satellites in terms of the volume, speed, and economics of data and voice communication.  Submarine cables are also an important means of power transmission—particularly in light of the ongoing development of offshore alternative energy generation facilities, such as wind farms.

Submarine cables clearly play a critical role in global communications.

For the United States, they provide connectivity between the contiguous United States and Alaska, Hawaii, American Samoa, Guam, the Northern Marianas, Puerto Rico, and the U.S. Virgin Islands – as well as connectivity with the rest of the world.  They also support critical commercial, economic and national security endeavors. and they carry a majority of civilian, military and government offshore communications traffic. 

The success of submarine cables owes much to treaties that have been negotiated since 1884.  Submarine cables are also subject to domestic regulations by most nations, including the United States which has a broad suite of domestic regulations applicable to cable-laying, maintenance, repair and removal operations.

250 MCM conversion to 250 KCMIL (MCM to KCMIL)

First, KCMIL is an abbreviation for a Circular Mil. Furthermore, a circular mil is a unit of area, equal to the area of a circle with a diameter of one mil (one-thousandth of an inch). It’s important to note that MCM is a measurement abbreviation for one thousand circular mils. Furthermore, this is a historical measurement of electrical & electronic wire & cable gauge sizes that has been passed down through generations. Accordingly,

1 MCM = 1 kcmil = 0.5067 square milimeters. A mil is 1/1000 inch

Thus, 250 MCM is equal to 250 KCMIL. They are interchangeable when describing the gauge size, or AWG size of your electrical and electronic wire & cable. We manufacture cable using both 1000 KCMIL and 1000 MCM to describe the wire & cable sizes.

250 MCM / 250 KCMIL Voltage Drop Calculations

First, the voltage drop V in volts (V) is equal to the wire current I in amps (A) times 2 times one-way wire length L in feet (ft) times the wire resistance per 1000 feet R in ohms (Ω/kft) divided by 1000:

V_drop (V) = I_wire (A) × R_wire(Ω)

= I_wire (A) × (2 × L_(ft) × R_wire(Ω/kft) / 1000_(ft/kft))

Therefore, the voltage drop V in volts (V) is equal to the wire current I in amps (A) times 2 times one way wire length L in meters (m) times the wire resistance per 1000 meters R in ohms (Ω/km) divided by 1000:

V_drop (V) = I_wire (A) × R_wire(Ω)

= I_wire (A) × (2 × L_(m) × R_{wire (Ω/km)} / 1000_(m/km))

3 phase calculation

First, the line to line voltage drop V in volts (V) is equal to square root of 3 times the wire current I in amps (A) times one way wire length L in feet (ft) times the wire resistance per 1000 feet R in ohms (Ω/kft) divided by 1000:

V_drop (V) = √3 × I_wire (A) × R_wire (Ω)

= 1.732 × I_wire (A) × (L_(ft) × R_{wire (Ω/kft)} / 1000_(ft/kft))

The line to line voltage drop V in volts (V) is equal to square root of 3 times the wire current I in amps (A) times one way wire length L in meters (m) times the wire resistance per 1000 meters R in ohms (Ω/km) divided by 1000:

V_drop (V) = √3 × I_wire (A) × R_wire (Ω)

= 1.732 × I_wire (A) × (L_(m) × R_{wire (Ω/km)} / 1000_(m/km))

Wire diameter calculations

The n gauge wire diameter d_n in inches (in) is equal to 0.005in times 92 raised to the power of 36 minus gauge number n, divided by 39:

d_n (in) = 0.005 in × 92^(36-n)/39

The n gauge wire diameter d_n in millimeters (mm) is equal to 0.127mm times 92 raised to the power of 36 minus gauge number n, divided by 39:

d_n (mm) = 0.127 mm × 92^(36-n)/39

Wire cross-sectional area calculations

First, The n gauge wire’s cross-sectional area A_n in kilo-circular mils (kcmil) is equal to 1000 times the square wire diameter d in inches (in):

A_n (kcmil) = 1000×d_n² = 0.025 in² × 92^(36-n)/19.5

Therefore, The n gauge wire’s cross-sectional area A_n in square inches (in²) is equal to pi divided by 4 times the square wire diameter d in inches (in):

A_n (in2₎ = (π/4)×d_n² = 0.000019635 in² × 92^(36-n)/19.5

Finally, The n gauge wire’s cross-sectional area A_n in square millimeters (mm²) is equal to pi divided by 4 times the square wire diameter d in millimeters (mm):

A_n (mm2₎ = (π/4)×d_n² = 0.012668 mm² × 92^(36-n)/19.5

Wire resistance calculations

First, the n gauge wire resistance R in ohms per kilofeet (Ω/kft) is equal to 0.3048×1000000000 times the wire’s resistivity ρ in ohm-meters (Ω·m) divided by 25.4² times the cross-sectional area A_n in square inches (in²):

R_n (Ω/kft) = 0.3048 × 10⁹ × ρ_(Ω·m) / (25.4² × A_n (in2₎)

Finally, the n gauge wire resistance R in ohms per kilometer (Ω/km) is equal to 1000000000 times the wire’s resistivity ρ in ohm-meters (Ω·m) divided by the cross-sectional area A_n in square millimeters (mm²):

R_n (Ω/km) = 10⁹ × ρ_(Ω·m) / A_n (mm2₎
