3M 7100025924 Bus Bar Heat Shrink Tubing 20 Ft

Product Description

The 3M 7100025924 is a heavy-duty bus bar heat shrink tubing engineered for electrical insulation and protection of rectangular, square, and round bus bar conductors. Constructed from cross-linked, flame-retardant, track-resistant polyolefin, this tubing shrinks uniformly to conform tightly around irregular bus bar profiles. The expanded inner diameter ranges from 6.67 to 10.86 inches, allowing installation over large conductor assemblies before heat is applied. Licensed electricians and electrical contractors typically specify this product for switchgear, distribution panels, and industrial power bus applications where durable, code-compliant insulation is required.

This tubing is suited for commercial and industrial electrical installations where bus bars require reliable dielectric protection after assembly or repair. It performs in switchgear enclosures, transformer connections, and power distribution bus work where flame-retardant insulation is a code or specification requirement. Each unit covers 20 linear feet of bus bar, making it practical for large-scale panel builds or service work requiring consistent coverage across multiple sections.

Key Features

• Cross-linked polyolefin construction provides flame-retardant and track-resistant performance
• Expanded OD range of 6.67 to 10.86 inches accommodates rectangular, square, and round bus bar profiles
• Shrinks to conform tightly to irregular conductor shapes without gaps or voids
• 20-foot length supports large panel builds and multi-section bus bar insulation jobs
• Sold in minimum quantities of 20 feet per unit of measure

Compatibility

Designed for use on rectangular, square, or round bus bar conductors in commercial and industrial power distribution assemblies. Specific model or equipment compatibility was not provided in the product data.

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 or positioning heat shrink tubing. Use a calibrated heat gun to apply even heat along the tubing length, working from one end to avoid trapping air. Do not use an open flame to shrink this tubing.
