HU-220 MK3 Single Core Insulated Main Power Cable
Breakthrough in power cable engineering — hollow-core design for superior transmission speed and thermal stability.
─────────────────────────────────────────────
The HU-220 MK3 represents the latest evolution in Monitor Acoustics' reference-grade power inlet cables—our most advanced and largest-gauge design to date. Built with 6N LC-OFC (Long-Crystal Oxygen-Free Copper) and featuring a 23.3mm² conductor cross-section, the MK3 offers outstanding current handling up to 600V / 90A, and is the go-to solution for users who demand high current flow, superior dielectric properties, and uncompromised energy stability.
Inspired by aerospace-grade manufacturing technologies similar to those used by NASA, the MK3 incorporates a proprietary hollow-core structure that increases internal airflow. This design not only accelerates current transmission but also dissipates heat more efficiently, maintaining a temperature close to ambient even under sustained load. The result is a cool-running, high-speed conductor ideal for critical applications where thermal buildup must be minimized.
The conductor itself is formed by six twisted bundles, each composed of 55 strands of 0.30mm 6N LC-OFC wire, significantly increasing the conduction surface area and ensuring extremely stable current flow. This enhanced geometry delivers robust, full-bodied power delivery—essential for high-load circuits and audiophile-grade power distribution.
Surrounding the conductor is a multi-layer dielectric shielding system:
- The first layer is a high-dielectric PTFE (Teflon) tape, known for its exceptional insulation, EMI resistance, and chemical durability.
- This is followed by a semi-rigid PVC layer for structural support.
- Around the cable, a 33-strand 0.18mm OFC shield wire is helically wound for uniform coverage, then wrapped in a high-performance copper foil shield.
- The outermost layer is a dynamically cross-linked thermoplastic elastomer (TPV) jacket—resistant to weather, oil, chemicals, and temperature extremes from -55°C to 135°C.
The TPV jacket, offered in white or brown, combines the flexibility of rubber with the durability of plastic. It also features excellent tactile grip and anti-slip properties, making installation both secure and efficient. Furthermore, the MK3 incorporates multiple functional nano-materials, including infrared-responsive nano powders that enhance electrical insulation, vibration damping, and contribute to more refined power transmission characteristics.
With its cutting-edge materials, hollow-core acceleration design, and high-purity conductor system, the HU-220 MK3 is the perfect choice for those who refuse to compromise on performance—ensuring uninterrupted, powerful, and efficient power delivery from the entry point of your system.
