3M 7100025923 Bus Bar Insulation Tubing 20 Feet

Product Description

The 3M 7100025923 is a heat-shrink bus bar insulation tubing designed to provide dielectric protection over rectangular, square, or round bus bars in electrical distribution equipment. Constructed from a specially formulated cross-linked polyolefin, the tubing is flame-retardant and track-resistant, making it suitable for demanding electrical environments. It is sold in a 20-foot case quantity and accommodates a wide range of bus bar profiles with a recovered outer diameter range of 5.43 to 8.86 inches. Electricians and electrical contractors working on switchgear, panelboards, and bus duct assemblies are the primary installers of this product.

This tubing is applied in commercial and industrial electrical installations where exposed bus bars require insulation sleeving. Its wide shrink range allows a single tubing size to cover multiple bus bar dimensions, reducing the need to stock multiple sizes. Typical applications include power distribution centers, motor control centers, and switchgear assemblies where bus bar insulation is required for personnel protection and system reliability.

Key Features

• Cross-linked polyolefin construction provides flame-retardant and track-resistant performance
• Recovered OD range of 5.43 to 8.86 inches accommodates rectangular, square, and round bus bars
• Heat-shrink design conforms tightly to bus bar profiles for consistent insulation coverage
• Sold in 20-foot case quantity to cover extended bus bar runs
• Suitable for use in switchgear, panelboards, and power distribution equipment

Compatibility

Designed as an OEM-style insulation sleeving solution for rectangular, square, or round bus bars within the recovered outer diameter range of 5.43 to 8.86 inches, as found in commercial and industrial electrical distribution equipment.

Installation Notes

Installation is performed by licensed electricians. De-energize and lockout/tagout all affected circuits before applying any bus bar insulation tubing in accordance with NFPA 70E electrical safety requirements. Apply uniform heat evenly along the tubing length using an appropriate heat gun to achieve full shrinkage without scorching. Confirm full recovery and continuous coverage before re-energizing the system.
