Fiberglass wire loom provides exceptional thermal management, capable of reducing radiant heat by up to 60%. Constructed from specialized fiberglass heat sleeve materials, this protective solution shrinks and expands to form a secure, custom fit around cables and terminals. Here’s what you need to know about this high-performance insulation option.

What Is a Fiberglass Wire Loom?

A fiberglass wire loom consists of a braided sleeve made from glass fibers embedded in a high-temperature resin matrix. This structure is woven around conductors and an outer jacket, offering robust insulation and physical protection in demanding environments.

How Does Fiberglass Wire Loom Work?

Fiberglass acts as a thermal insulator, effectively blocking heat transfer through conduction—the process by which heat travels through solid materials like walls or cables. While many insulation materials target conductive heat loss, fiberglass also serves as a radiant barrier, reflecting heat away from sensitive components.

Is Fiberglass an Electrical Conductor, and Does It Prevent Heat Loss?

No—fiberglass does not conduct electricity. Both the glass fibers and the resin used in its construction are electrically non-conductive. At the same time, fiberglass insulation traps heat, preventing it from migrating to cooler areas. This makes it ideal for assemblies operating under extremely high temperatures.

Key Features of Fiberglass Wire Loom

• Superior high-temperature and oxidation resistance

• Excellent flame retardancy and fire resistance

• Maintains circuit integrity even under direct flame or extreme heat

• Optional stainless steel braid for enhanced mechanical protection

Final Thoughts

Selecting the right wire loom can be challenging given the range of options available. Understanding your application requirements and operating environment is the first step toward ensuring optimal cable protection. For specialized needs, consider a customized fiberglass wire loom to maximize performance, safety, and efficiency.
