STP Wire Stripping Problem Background:
From the beginning, Mil-Spec Tefzel Shielded Twisted 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.
That has been the standard way to remove twisted pair jackets since the introduction of this type of wire.
This time consuming and innacurate process has obvious disadvantages when compared to the TS-7000:
- Loss of blood (Ever had the experience?)
- HR Department liability (Workers Comp)
- Reduced productivity
- Loss of time
- Loss of wire and shield integrity

Even though this wire appears to be properly stripped, there are problems that result from hand use of a razor:
- Shield nicks, cuts, and other damage (High resistance)
- Internal wire damage resulting in open circuit / shorts
- Potential avionic / electrical damage
- Inflight component / systems failure
- Potential aircraft damage from lost / misplaced blades
- Aircraft interior damage from open blades

A closer look a the base 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 will expand any nicks in the inner wire jacket and 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 couple extra ounces of unintended force while ringing the jacket can compromise the sheilds integrity. |

The Revolutionary TS-7000 Wire Stripper

Tool operation is simple:
1. Adjust the integral strip length gauge by gripping the dies to keep the tool's core from rotating, loosen the collet nut and slide the wire stop to the desired length. |
| |
|
|
2. Insert the wire into the tool until it contacts the internal wire stop.
3. Clamp the dies around the wire by pushing the thumb actuator forward. |
| |
|
|
4. Pull the wire stripper along the length of wire. As the stripper moves along the helical jacket, the dies/blades rotationally track the wire's profile and create two helical slits in the outer jacket. A simple twist of the slitted portion results in the jacket halves separating as shown.
QUICK... EFFICIENT... NO SHIELD DAMAGE !
