3M 7100025922 Bus Bar Tubing 3.28-5.57in Od 20ft

Product Description

The 3M 7100025922 is a heat-shrink bus bar tubing designed to insulate and protect rectangular, square, and round bus bars in electrical distribution systems. Constructed from cross-linked, flame-retardant, track-resistant polyolefin, this tubing shrinks to conform tightly to the bus bar profile upon application of heat. It is sold in a 20-foot case quantity, making it suited for shop stocking or larger panel and switchgear jobs. The outer diameter range of 3.28 to 5.57 inches accommodates a wide variety of bus bar cross-sections commonly found in commercial and industrial electrical assemblies. Licensed electricians and electrical contractors are the primary installers.

This tubing is used in commercial and industrial electrical installations where bus bars require insulation, protection from environmental contamination, or phase identification. Typical applications include switchgear panels, distribution boards, bus duct assemblies, and transformer connections. The cross-linked polyolefin construction provides resistance to tracking and flame propagation, which is important in high-voltage bus bar environments where arc and fire risk must be managed.

Key Features

• Cross-linked polyolefin construction provides flame retardancy and track resistance
• Fits rectangular, square, and round bus bar profiles
• OD shrink range of 3.28 to 5.57 inches accommodates large bus bar cross-sections
• 20-foot length per case quantity suitable for stocking or multi-bar jobs
• Heat-shrink design conforms tightly to irregular bus bar shapes on application

Compatibility

Designed as an OEM-style insulation solution for rectangular, square, and round bus bars in commercial and industrial electrical switchgear and distribution panel applications.

Installation Notes

Installation should be performed by a qualified electrician following applicable NEC requirements. De-energize and lock out the bus bar assembly completely before applying tubing. Use a calibrated heat gun to apply even, consistent heat along the tubing to achieve full shrink without scorching the material. Do not use open flame as a heat source.
