Rubadue Expands Litz Wire Portfolio to Support Aerospace Electrification

Rubadue Wire has announced the expansion of its high-performance Litz wire offerings to include new tape-wrapped configurations using PET (polyester) and polyimide insulation. This development enhances the company’s capabilities in high-frequency power electronics and positions it as a key supplier for aerospace applications demanding lightweight, thermally resilient, and space-efficient wiring solutions.

Engineered for High-Frequency, High-Reliability Systems

The new tape wrap options, PET rated to 155°C and polyimide rated to 180°C or higher, are designed for engineers working in environments where electrical integrity and thermal performance are non-negotiable. These materials offer improved dielectric strength and tighter coil geometries, making them ideal for compact, high-voltage systems such as satellite payloads, electric propulsion modules, and eVTOL platforms.

Rubadue’s polyimide tape, in particular, is compatible with lead-free reflow soldering, a critical requirement for aerospace-grade electronics. The company’s ability to insulate Litz wires larger than 8 AWG further expands its utility in power-dense systems where traditional wire formats fall short.

Supporting Aerospace Innovation from Orbit to Urban Air Mobility

Rubadue’s tape-wrapped Litz wire is already being adopted in aerospace and defense programs that require high-reliability, low-weight power distribution. In satellite systems, where every gram and cubic centimeter counts, the thin insulation layers and high fill factor of Rubadue’s wire help optimize payload efficiency. For emerging eVTOL aircraft, which rely on compact, high-frequency power electronics for propulsion and flight control, Rubadue’s offerings provide the thermal resilience and electrical performance needed to meet certification standards.

According to a 2025 report by MarketsandMarkets, the global market for aerospace-grade wire and cable is projected to exceed $12 billion by 2030, driven by electrification trends and the rise of hybrid propulsion systems. Rubadue’s expansion into tape-wrapped configurations aligns with this trajectory, offering engineers a versatile toolset for next-generation designs.

Domestic Manufacturing with Global Reach

All tape-wrapped Litz wire is manufactured in the United States, ensuring supply chain stability and short lead times for domestic aerospace programs. Rubadue also supports international customers through its global distribution network, providing engineering consultation, rapid prototyping, and low minimum order quantities to accommodate both R&D and production needs.

Looking Ahead

As aerospace platforms evolve toward electrification and modularity, the demand for flexible, high-performance wire solutions will only grow. Rubadue’s latest expansion reflects a commitment to meeting these needs with precision, reliability, and environmental responsibility. For aerospace engineers designing the next generation of satellites, eVTOLs, and defense systems, Rubadue’s tape-wrapped Litz wire offers a compelling blend of performance and practicality.
