Highlights
  • Inline splice for joining tape shield, wire shield, UniShield® or longitudinally corrugated shielded power cables
  • Special electrode design of the kit reduces the electrical stress at a critical cable/splice interface
  • Designed for inline splicing, feeder and distribution circuits, size transition splicing, direct burial installations and submerged locations
  • Silicon rubber-splice body provides good high and low temperature performance, and the EPDM rubber jacket offers physical protection
  • Rated for 25/28 kV cables
  • High-voltage, production-tested for partial discharge and AC ensure reliability

3M™ Cold Shrink QS-III Inline Shielded Cable Splices 5524A, 5525A and 5526A Series are inline splices for joining 25/28 kV tape shield, wire shield, UniShield® or longitudinally corrugated (LC) shielded power cables. It is a cold shrink design.

The cold shrink splice body is a one-piece molded design made of specially formulated silicone rubbers, while the jacketing is made of EPDM rubber for its special physical properties. Each splice is high-voltage production tested to ensure reliability. Kits can be ordered with connectors packed in the kit, or the kit and connector can be ordered as separate items. Meets requirements of IEEE 404. Each kit makes one splice. Note: Cable sizes shown below are for standard insulation thickness. Final determining factor is cable insulation O.D.

Suggested applications
  • For inline splicing
  • For feeder and distribution circuits
  • For Tape, Wire, UniShield® & Longitudinally corrugated (LC) shielded cables
  • For transitions from shielded to neutral power cables
  • For copper or aluminum conductors
  • For size transition splicing
  • For direct burial installations
  • For submerged locations
