Polywater SpliceMaster Sanding Cloth Rolls (SP-ROLL) are non-conductive 120 grit aluminum oxide sanding cloth for prepping medium and high voltage cable before splicing. They remove semicon shield residue, jacket polymers and other contaminants from the cable insulation. Polywater says these deposits can cause tracking or arcing, so they have to come off before the splice goes on.

Polywater warns that emery cloth and standard store-bought sandpaper can leave conductive grit residue on the cable, which could lead to cable failure. Only non-conductive sanding material should be used on cable insulation. Polywater also says never to abrade an energized cable.
| Material | Polywater's position |
|---|---|
| SP-ROLL non-conductive sanding cloth | Leaves no conductive grit that could cause tracking or arcing |
| Emery cloth | Can leave conductive grit that may lead to cable failure |
| Store-bought sandpaper | Can leave conductive grit that may lead to cable failure |
| Feature | What it means |
|---|---|
| Non-conductive | No conductive grit left behind to cause tracking or arcing |
| Cloth backing | Resists shredding and helps evenly "pencil" the semicon layer |
| Roll format | Unroll the roll and snip off only the length you need, which cuts waste |
Polywater recommends using SP-ROLL with its SpliceMaster DT dry towels. The towels are lint-free and have no fiber-bonding adhesives. Polywater says rags and other non-specified wipes can leave lint that causes tracking, and recycled rags can carry oils or contaminants. See the Polywater cleaning wipes guide for the Type HP and Type RP cleaners.
