TSP Wire Stripping Problem Background:

From the beginning, Mil-Spec Twisted Shielded Pair wire has defied every wire stripper available to installers, leaving a razor blade or knife as the best option for removing the outer jacket.  This time consuming method is imprecise, and it can easily lead to internal shorts between the center conductors and the shield, especially when solder sleeves are used for shield termination. With the increased use of RS-232, ARINC 429, and other types of data busses in todays aircraft electronics, this type of wire is now a major component of many avionics installations.

Ring and slit.

Historically, the best way to remove the jacket from twisted shielded wire has been a razor blade or knife. This time consuming and innacurate process has obvious disadvantages that would be best eliminated from your production area:

- Razor blade accidents / worker injury
- Resulting company bans on razor blade usage
- Reduced productivity / wasted time
- Loss of wire and shield integrity

A closer look reveals an area where shield and inner conductor damage occurred from slightly too much pressure while ringing the wire. This is one of the most common types of damage caused by hand stripping twisted pair wire.

When terminating the shield with a solder sleeve, the heat from the installation process expands nicks on the inner wire jacket. This can result in a shield-to-conductor short that is visibly hidden by the solder sleeve.

FACT: ..The Mil-Spec tin coated copper wire used to construct the braided shield for twisted pair wire is only .004" in diameter. Human hair is about .002" in diameter.

A slight increase in force while ringing the jacket can compromise the shield's integrity.
