Our new line of WetLink Penetrators (WLP) makes it easier than ever to install a cable penetrator on your cables. To ensure that your cable will perform well with WLP, your cable will need to be stripped correctly. Many cables are constructed with thick jackets, shielding, wrappers, or fillers that can make it tricky to properly strip cable. This guide will provide guidance on how to properly strip cable for use with WLP.

If you will be frequently stripping a lot of cable, we recommend getting a specialized jacket stripping tool. We like the Jonard CST-1900. It is easy to use and helps get clean, consistent strips on most types of cables.
The following picture shows the different parts of a cable. All cables will have a cable jacket and conductors. Shielding, wrapping, or fillers may or may not be present in the particular cable you are stripping.
- The cable jacket must be cut straight across, perpendicular to the cable. A straight, perpendicular cut is necessary to allow the cable jacket to seat fully into a WetLink Penetrator and ensure proper performance. A cable jacket that is not fully seated may not seal properly.
- Cable shielding, wrapping, and fillers must be removed cleanly. Any loose shielding, wrapping, or fillers may prevent the cable from seating fully in the penetrator or interfere with the seal.
- Avoid damaging the conductor insulation. Accidentally cutting the insulation may lead to shorts between the conductors.
1. Wearing a protective glove, bend the cable at the point that you want to cut. Bending the cable will make the jacket naturally want to split open when cut and makes it easier to see when you have cut completely through the outer jacket.
2. Using the knife, gently slice the jacket open by pulling the blade across the cable jacket. Keep the blade straight and perpendicular to the cable so the resulting cut is straight across and perpendicular to the cable. A straight, clean, perpendicular cut is necessary for proper performance when installed in a WetLink Penetrator.
3. Stop cutting once the jacket opens and you can see the conductor insulation or shielding/wrapping underneath.
4. Turn the cable around and repeat on the other side.
5. Continue the cut so it remains straight, perpendicular to the cable. Stop cutting once the jacket opens and you can see the conductor insulation or shielding/wrapping underneath.
6. Pull the jacket away from the rest of the cable. Inspect the cut and trim the remaining cable jacket if it is not straight.
7. Depending on the construction of the cable, there may be shielding, wrapping, or fillers remaining after removing the jacket. The next section provides tips on how to deal with these.
Many cables have some type of shielding or wrapping around the conductors and or fillers that help the cable maintain its shape. It’s important to cut these back cleanly to ensure proper installation in a penetrator. Loose shielding, wrapping, or fillers can prevent the cable from seating fully into a cable penetrator or interfere with proper sealing against the cable.
1. Remove any wrappers and cable fillers. Cut them as close to the strip as possible so they do not prevent the cable from seating fully in the penetrator or interfere with the seal.
2. If desired, certain fillers can be left intact as long as they fit completely through the penetrator bulkhead and do not prevent the cable from seating fully in the penetrator or interfere with the seal.
1. Metal braided shielding can be removed by pushing the shielding back on itself then clipping with wire clippers. Foil shielding can be unwrapped from the conductors and cut with scissors. Cut as close to the strip as possible so it does not prevent the cable from seating fully in the penetrator or interfere with the seal.
2. If desired, certain shielding can be left intact as long as it fits completely through the penetrator bulkhead and does not prevent the cable from seating fully in the penetrator or interfere with the seal.

- We recommend stripping the conductor insulation after the cable is installed in a penetrator. This makes it easier to insert the conductors through the penetrator bulkhead while avoiding damage to the conductors.
