3M 7100025926 Bus Bar Heat Shrink Tubing 20 Feet

Product Description

The 3M 7100025926 is a flame-retardant heat shrink bus bar tubing designed to protect and insulate rectangular, square, and round bus bars in electrical distribution systems. Constructed from a specially formulated cross-linked polyolefin, it offers track-resistant performance suited to demanding electrical environments. The tubing features an outer diameter range of 8.28 to 13.00 inches, allowing it to conform tightly to a wide range of bus bar profiles upon application of heat. Licensed electricians and electrical contractors working on switchgear, panelboards, and bus duct assemblies are the primary installers of this product.

This tubing is used in commercial and industrial electrical installations where bus bars require durable insulation and mechanical protection. It is appropriate for both new construction and retrofit applications involving low- and medium-voltage distribution equipment. The 20-foot length per case quantity makes it practical for larger bus bar runs or multi-section installations. Its cross-linked construction provides dimensional stability and resistance to tracking, making it a reliable choice in high-humidity or contaminated environments.

Key Features

• Cross-linked polyolefin construction provides enhanced mechanical strength and heat resistance
• Flame-retardant formulation meets requirements for electrical enclosure applications
• Track-resistant material reduces risk of surface degradation under electrical stress
• Fits rectangular, square, and round bus bar profiles with OD range of 8.28 to 13.00 inches
• Supplied in 20-foot lengths to accommodate longer bus bar sections

Compatibility

Designed as an OEM-style insulation solution for rectangular, square, and round bus bars commonly found in commercial and industrial switchgear and panelboard assemblies.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize and lock out all affected circuits before applying tubing to any bus bar. Apply heat evenly using an appropriate heat gun, working from one end of the tubing to the other to avoid trapping air. Do not use an open flame to shrink the tubing.
