3M 7100025929 Bus Bar Heat Shrink Tubing 20 Feet

Product Description

The 3M 7100025929 is a heavy-duty bus bar heat shrink tubing engineered for insulating and protecting rectangular, square, and round bus bars in high-voltage electrical installations. Constructed from a specially formulated, cross-linked, flame-retardant, track-resistant polyolefin, this tubing delivers reliable dielectric protection and long-term durability in demanding environments. It ships in a 20-foot length with an outer diameter range of 10.29 to 16.43 inches, providing coverage for a wide range of bus bar profiles. Licensed electricians and electrical contractors working on switchgear, panel boards, and power distribution assemblies are the primary installers.

This tubing is suited for commercial and industrial electrical applications where bus bars require insulation, phase identification, or mechanical protection. The polyolefin construction resists tracking and flame propagation, making it appropriate for use inside switchgear enclosures, transformer connections, and power distribution equipment. Its ability to conform to rectangular, square, or round bus bar shapes makes it a versatile option across multiple installation configurations.

Key Features

• Cross-linked polyolefin construction resists flame propagation and electrical tracking
• Fits rectangular, square, and round bus bar profiles
• Outer diameter range of 10.29 to 16.43 inches accommodates large bus bar sizes
• 20-foot length sold by the foot with a minimum quantity of 20 feet
• Heat-shrink design conforms tightly to bus bar surface upon application

Compatibility

Designed as an OEM-style insulating solution for large rectangular, square, and round bus bars found in commercial and industrial power distribution, switchgear, and panel board applications.

Installation Notes

Installation should be performed by a licensed electrician following applicable NEC requirements. De-energize and lock out the bus bar assembly completely before applying tubing. Use a heat gun with appropriate heat output to shrink the tubing evenly along the bus bar length, working from one end to avoid trapping air. Do not use an open flame as the heat source, as this may damage the tubing or surrounding components.
