And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.
Doesn't look like any data cable I know of. If I had to guess, it's a power cable in three phase, with fairly high voltage considering the massive dielectric shield around the copper. Anybody more knowledgeable got a better idea?
Right you are, Greg. The cross-section is for a power cable with integral shielded grounding. The small circle in the upper left looks like a coax cable used for signaling between monitor points in the transmission line. Telecom cables are much smaller and all those in the past ~20 years are combinations of several fibers in amongst a fair number of strength members and polymer seals.
"The Cable" (Gillian Cookson) interesting book on the first trans-Atlantic telegraph cable; the people, the technology, the success and the failures. Putting it into focus for it's place in time and history; one message alone sent by the British government made the governments investment back with interest. Though the Crimea War had ended, a Canadian regiment was about to sail for the Crimea and an undersea telegraph message stopped them.

ReplyDeleteAgreed. Power transmission. Otherwise you couldn't get more than one phone call through.

ReplyDeleteIt'd make a nice wall hanging in someone's den.

I thought undersea cables were optical fiber bundles.
ReplyDeleteMmmmmm, yummy!!! Sea food!!!
