3M 7100025928 Bus Bar Heat Shrink Tubing 50 Feet

Product Description

The 3M 7100025928 is a flame-retardant bus bar heat shrink tubing designed to insulate and protect rectangular, square, and round bus bars in electrical distribution systems. Manufactured from a specially formulated, cross-linked, track-resistant polyolefin, this tubing shrinks tightly around the bus bar profile to create a durable, protective sleeve. With an expanded inner diameter range of 10.29 to 16.43 inches, it accommodates a wide variety of bus bar sizes. This product is sold in 50-foot lengths and is installed by licensed electricians working on switchgear, panel boards, and other high-current distribution equipment.

This tubing is suited for commercial and industrial electrical applications where exposed bus bars require insulation, mechanical protection, or phase identification. Typical installation scenarios include retrofitting or reinsulating bus bars inside switchgear cabinets, distribution panels, and transformer enclosures. The cross-linked polyolefin construction provides resistance to electrical tracking, making it appropriate for high-voltage bus bar environments where surface contamination is a concern.

Key Features

• Cross-linked, flame-retardant polyolefin material resists electrical tracking
• Expanded OD range of 10.29 to 16.43 inches fits rectangular, square, and round bus bars
• Shrinks to conform tightly to the bus bar profile for a secure fit
• 50-foot length per unit provides enough material for multiple bus bar sections
• Suitable for high-current electrical distribution environments

Compatibility

Designed as an OEM-style replacement or upgrade insulation solution for rectangular, square, and round bus bars commonly found in switchgear, panelboards, and electrical distribution enclosures.

Installation Notes

Installation should be performed by a licensed electrician following applicable NEC guidelines. De-energize and lock out all circuits before applying heat shrink tubing to any bus bar. Use an appropriate heat gun set to the recommended shrink temperature for polyolefin tubing, and apply heat evenly along the length of the tubing to avoid incomplete shrink or bubbling. Do not energize equipment until the tubing has fully cooled and is confirmed to be seated correctly.
