How to use the 3M3529 cold splice

The 3M3529 cold splice is installed by preparing the cables, positioning the splice over the conductors, and carefully removing the core to allow the silicone body to shrink and provide insulation and protection.Tools and Materials Needed3M3529 Cold Shrink Splice kitCable cleaning pad or clothCable strippers and cuttersOptional: silicone grease (if supplied with the kit)Personal protective equipment (gloves, safety glasses)Step-by-Step Installation1. Prepare the CablesStrip the cable insulation according to the dimensions specified in the kit instructions, ensuring the conductor is exposed without damaging it .For jacketed concentric neutral (JCN) or concentric neutral (CN) cables, carefully bend back neutral wires over the edge of the cable jacket to allow proper connection .Clean the cable surface with the provided cleaning pad to remove dirt, moisture, or oxidation. 2. Position the SpliceSlide the cold shrink splice over the prepared cable ends before connecting the conductors .Ensure the splice body is fully stretched on its removable core. 3. Connect the ConductorsUse the appropriate connector (compression or shearbolt) to join the conductors securely .For JCN or CN cables, connect the neutral wires as instructed in the kit manual. 4. Install the Cold Shrink BodyCenter the splice body over the joint.Carefully remove the inner core, allowing the silicone body to shrink uniformly around the cable and connector .Ensure the splice is snug and fully covers the exposed conductors and connectors. 5. Apply Additional SealingIf the kit includes mastic tape or silicone grease, apply it at the semi-conductive step or around the splice to enhance moisture protection .Avoid using non-supplied grease, as it may be absorbed into the splice and compromise insulation. 6. Final InspectionVerify that the splice is fully seated, with no gaps or exposed metal.Check that the neutral wires are properly positioned and that the splice provides uniform pressure around the cable.Tips and PrecautionsInstall in a clean, dry environment to prevent contamination.Do not remove the splice core until the conductors are fully connected.Avoid stretching the splice body excessively beyond the kit's specifications.Cold shrink splices provide inward pressure and uniform insulation, making them ideal for underground or outdoor applications . Following these steps ensures a reliable, weatherproof, and electrically safe splice using the 3M3529 cold splice kit.
