HU-220 MK2 Single Core Insulated Power Cable
Extra-large gauge. Massive current handling. Ultra-fast power delivery. Designed to transmit over 100A with stability and confidence.
─────────────────────────────────────────────
The HU-220 MK2 is the largest-gauge power inlet cable ever developed by Monitor Acoustics, crafted for uncompromising users who demand maximum current flow, high voltage endurance, superior dielectric strength, and the highest copper purity. With a conductor cross-sectional area of 22.7mm², made of 5N LC-OFC (Long-Crystal Oxygen-Free Copper), it supports up to 600V / 90A with ease—ideal for heavy-load electrical trunks or reference-grade power distribution systems.
Its 22.7mm² core conductor consists of 7 twisted bundles, each made from 64 strands of 0.254mm 5N OFC wire, precisely arranged for minimal resistance and superior current dynamics. This large conductor ensures ultra-low impedance and superior current-carrying performance, providing a robust backbone for even the most power-hungry audio or electrical setups.
The insulation system is equally impressive. The conductor is first wrapped in a layer of PTFE (Teflon) tape—a high-dielectric, chemically resistant, and temperature-tolerant material known as the "king of plastics". This is followed by an inner PVC layer. For shielding, a 30-strand 0.18mm OFC copper wire is helically wound around the cable, overlaid with thick copper foil, and finally encased in a durable gray PVC jacket. This multi-layer configuration effectively suppresses EMI/RFI interference, enhances transmission efficiency, and ensures stable energy flow under demanding conditions.
Thanks to its stress-free copper, multi-layer shielding, and superior dielectric properties, the HU-220 MK2 sets a new standard for high-current in-wall cables. It delivers a clean, abundant power path to the breaker box and is capable of driving multiple sub-distribution units from a single trunk line—transforming how power is distributed in high-performance systems.
