No, in fact they degrade the cable a little. See http://duxcw.com/digest/Howto/network/cable/cable2.htm for more info on the type of cable. Use solid core wire for cables that long. Be sure you have CAT 5 RJ-45 plugs designed for solid core wire.

One set of pins is connected by wires from the same twisted pair and the other set is not. One set works and the other set does not. Larry
Q. Does the order of the colors of the wires in a straight-thru twisted-pair network cable matter as long as both ends are the cable are wired the same?
A. You can use either standard color code, or invent you own, if desired. I use the 568A color code and it is the “preferred standard.” The colors do not matter, but the choice of wires does. Simply making both ends the same is not sufficient. The Ethernet interface uses four of the eight pins in an RJ-45 plug. Each end of an Ethernet cable connects to a transmitter and a receiver. A transmitter uses two pins and a receiver uses two pins. The two pins (+ and -) on the transmitter have to be connected to the corresponding pins (+ and -) of the receiver at the other end by wires in the SAME twisted pair and vice versa. A transmitter is not connected to a receiver by one wire from one pair and a second wire from a DIFFERENT pair. As the pins that are used, 1, 2, 3, and 6, are not sequential, one cannot simply match ends in a convenient manner and properly connect a transmitter to a receiver with wires from the SAME twisted pair.
