Cable specs

I notice cable manufactures listing the Velocity of Propogation of their products in terms of percentages, ie. Signal Cable 78 %, Cobalt Cables 66%. I understand that a charged wave moves (propogates) steadily along at exact distances and times (well at least in theory or a perfect world) but how does this relate to these percentages, information I have seen expresses these waves in terms of linear equations.

When comparing these two cables I notice that the capacitance of the Cobalt Cable is higher than that of the Signal AC2.

Can anybody explain?

:confused:

I know that the capacitance of the cable is the ability for it to store an electrical charge.

    bump!

    Nobody knows what Velocity of propogation means? Well I will call one of the cable companies and get an explanation. They list this value in their specs. Will post if I can get in answer in english.:D

    I have no idea what all that hooey means, makes no difference to me at all. If you do want to know, call Signal, Frank is a real nice guy...and I would bet he can expound upon that for you.
    CTC BBQ Amplifier, Sonic Frontiers Line3 Pre-Amplifier and Wadia 581 SACD player. Speakers? Always changing but for now, Mission Argonauts I picked up for $50 bucks, mint.

    Speed of Transmission= Velocity of Propogation

    How fast is the cable? You're going to need a big, long, hunk of cable before speed is affected.

    Thank you, looks like a nothing specification for my big 3 ft. run!!:)
