3M 7010319298 Bus Bar Heat Shrink Tubing 50 Feet

Product Description

The 3M 7010319298 is a bus bar heat shrink tubing designed to protect and insulate rectangular, square, and round bus bars in electrical distribution and power systems. Constructed from a specially formulated, cross-linked polyolefin compound, it is flame-retardant and track-resistant, meeting the demands of commercial and industrial electrical installations. The tubing ships in a 50-foot case quantity and features an expanded outer diameter range of 15.43 to 24.14 inches, allowing it to conform tightly to bus bar profiles upon heat application. Licensed electricians and electrical contractors working on switchgear, bus duct, and power distribution equipment are the primary installers.

This tubing is suited for bus bar insulation and protection in medium- to large-scale electrical infrastructure. Typical applications include switchgear assemblies, transformer connections, bus duct terminations, and power distribution panels where durable, flame-retardant insulation is required. The cross-linked polyolefin construction maintains dimensional integrity under elevated operating temperatures common in high-current distribution environments.

Key Features

• Cross-linked polyolefin construction provides flame-retardant and track-resistant performance
• Fits rectangular, square, and round bus bar profiles
• Expanded OD range of 15.43 to 24.14 inches accommodates large bus bar sizes
• 50-foot case quantity supports large-scale or multi-point installations
• Shrinks to conform tightly to bus bar surfaces upon heat application

Compatibility

Designed as an OEM-style insulation solution for rectangular, square, and round bus bars in commercial and industrial power distribution systems.

Installation Notes

Installation should be performed by a licensed electrician following applicable NEC guidelines. De-energize and lock out all affected electrical circuits before handling or applying tubing. Use a calibrated heat gun to apply uniform heat, working along the length of the tubing to avoid scorching or uneven shrink. Do not use an open flame as a heat source.
