Nordost Heimdall 3 Power Cord

Three silver-plated conductors, Micro Mono-Filament construction, and AC-optimized shielding

The Heimdall 3 is the entry point to Nordost’s Norse 3 power cord range, positioned below Frey 3 and Tyr 3. Its design combines conductor isolation, mechanical tuning, and electromagnetic shielding to provide a controlled path for power delivery.

Nordost’s proprietary Micro Mono-Filament construction wraps a single FEP filament around each of the three silver-plated, solid-core oxygen-free copper conductors before they are encased in extruded FEP insulation. This creates a virtual air dielectric, minimizing contact between the conductors and their surrounding insulation to provide electrical isolation and mechanical damping. Mechanically tuned conductor lengths further address resonance behavior.

Shielding for the AC Connection

AC-optimized shielding provides 90% coverage and is designed to contain electromagnetic energy generated by the cable while reducing susceptibility to external interference. The US version is terminated with a NEMA wall plug and an IEC-C15 (15 A) equipment connector.
