3M 5815-b9 Modular Splicing Kit 15 Kv

Product Description

The 3M 5815-b9 is a modular splicing kit designed for joining medium-voltage power cables in the 15 kV class. It provides a reliable, field-installed splice for jacketed concentric neutral, tape shield, unshielded, and wire shield cable types. Rated at 600 amps and compatible with 2 AWG stranded and 1 AWG compact or solid conductors, it uses an aluminum compression connector to complete the electrical joint. Electricians and utility cable splicers install this kit in underground distribution and industrial feeder applications where a quick, modular splice method is required.

This kit is suited for medium-voltage cable splicing in residential, commercial, and industrial distribution systems operating at 15 kV or 25 kV. It covers a range of cable constructions including jacketed concentric neutral, tape shield, unshielded, and wire shield designs. The modular quick adapter format is intended for field crews completing primary cable repairs, new service extensions, or scheduled maintenance splices on aluminum or copper conductor feeders.

• Rated for 15 kV and 25 kV medium-voltage cable systems
• 600-amp current rating for primary feeder applications
• Compatible with jacketed concentric neutral, tape shield, unshielded, and wire shield cable types
• Accepts 2 AWG stranded and 1 AWG compact or solid conductors
• Aluminum compression connector included for secure, low-resistance electrical joint
• Modular quick adapter design for efficient field installation

Compatibility

Designed for use with jacketed concentric neutral, tape shield, unshielded, and wire shield cables at the 2 AWG stranded or 1 AWG compact and solid conductor sizes in 15 kV and 25 kV distribution systems.

Installation Notes

Installation should be performed by a licensed electrician or qualified cable splicer in accordance with NFPA 70 (NEC) Article 310 and applicable utility work practices. De-energize, lock out, and tag out the circuit before beginning any splicing work. Follow the kit instruction sheet for proper conductor preparation, compression tool selection, and splice body assembly sequence. Do not apply power until all components are fully seated and insulation restoration is complete.
