How to Install the R2T28M4-N0350 Shrink Fit Silicone Rubber Termination
This guide provides detailed instructions for the safe and proper installation of the R2T28M4-N0350 Shrink Fit Silicone Rubber Termination for tape shielded cables, covering cable preparation, ground braid installation, lug connection, and termination application.
Estimated time: 1h 30m
Tools needed:
Crimping tool, Soldering iron, Wire strippers, Cable knife, Measuring tape or ruler, Safety glasses
Supplies needed:
R2T28M4-N0350 Silicone Rubber Termination kit, Silicone lubricant (grease), Gray silicone rubber electrical tape, Constant force spring, Preformed ground braid, Sealing mastic, Copper foil tape, Gloves, Vinyl tape, Terminal lug or connector, Approved solvent, Aluminum oxide abrasive (grit 120 or finer)
- Ensure Safety and Prepare for Installation
DANGER: All apparatus must be de-energized during installation or removal of parts. Do not touch or move energized products. Verify the R2T28M4-N0350 kit contents are complete and undamaged. Confirm all components fit the cable and mating products. Read all instructions thoroughly and have all required tools and supplies ready, maintaining cleanliness throughout the procedure.
- Prepare the Cable
Check that the cable size fits within the termination range. Train the cable into position and cut it to the required length. Prepare the cable using the dimensions specified in Table 1 for jacket removal length, allowing for terminal lug depth and growth allowance. Ensure 1 inch (25mm) of tape shield and insulation are exposed. Prevent the tape shield from unrolling by securing its edge with a single wrap of the supplied copper foil tape.
- Install the Ground Braid
Wrap one band of mastic around the cable jacket 1/4 inch (6mm) from the jacket end, using 50% stretch, and cut flush. Position the preformed ground braid with the short tail over the tape shield and the solder block centered over the mastic strip. Secure the ground braid to the cable jacket with vinyl tape and press the solder block into the mastic. Apply a second mastic band over the solder block and previous mastic, maintaining the 1/4 inch (6mm) dimension, and cut flush. Wrap two half-lapped layers of vinyl tape around the mastic seal. Wrap the ground braid around the cable tape shield one complete wrap, trim any excess, and secure it in place with the constant force spring, wrapping in the same direction as the ground braid. Cinch the spring after the final winding and secure it with two wraps of vinyl tape.
- Install the Terminal Lug or Connector
Verify that the termination assembly fits over the selected lug. If it does not, clean the insulation and slide the termination onto the cable before installing the lug, but do not remove the core at this time. Position the connector or lug and crimp it according to the manufacturer’s directions, avoiding crimping the last 3/8 to 1/2 inch of the connector. Remove any excess oxide inhibitor and all sharp crimp flashings and edges after crimping.
- Clean Cable Insulation and Lug Barrel
Wipe the cable insulation with an approved solvent, ensuring the solvent does not touch the semi-conductive insulation shield. If abrasive cleaning is necessary, use only aluminum oxide abrasive (grit 120 or finer) on the insulation only, never on the semi-conductive shield. Be careful not to reduce the cable insulation diameter below the kit's allowed specifications.
- Install the Termination Body
Create a track-resistant moisture seal between the termination insulator and the lug/connector by wrapping a band of gray silicone rubber electrical tape around the base of the terminal lug. If the barrel diameter is equal to or greater than the cable primary insulation, use no more than two layers. If smaller, build up the tape band to equal the insulation diameter. Liberally coat the edge of the semi-conductive insulation shield with silicone grease to fill the step at the cut-off. For lower terminations with a fold-down skirt, pull the loose end of the removable core through the top until it is flush with the bottom of the termination. Slide the termination body onto the cable, aligning it with the forward edge of the mastic seal. Carefully remove the core by unwinding it counter-clockwise, starting with the loose end. Ensure the termination body, not the core, is butted against the leading edge of the mastic seal. Do not push or pull the termination assembly during core removal.
- Complete Moisture Seal and Ground Connection
Apply a thin film of silicone lubricant to the skirt and mastic seal area, but avoid lubricating the skirt tabs. Carefully fold down the skirt over the mastic seal. Complete the lug area moisture seal using the remaining gray silicone rubber electrical tape, overlapping the termination insulator by approximately 1 inch and extending the tape wrapping over a non-crimped region of the lug/connector barrel with a half-lap configuration. Finally, connect the ground braid to the system ground and confirm that the High-K step does not exceed 1.5 inches.
