The HU-100M is a single-core insulated grounded power cable designed by Monitor Acoustics to deliver high-speed, uninterrupted power transmission to ground loops in high-performance electrical systems. Featuring a 5N LC-OFC high-purity long-crystal copper conductor with a cross-sectional area of 9.89mm², this cable is engineered to maintain low resistance and exceptional conductivity even under demanding conditions.
Its main conductor consists of 7 twisted strands, each composed of 20 copper wires (0.3mm diameter), ensuring a stable, high-capacity power flow. The conductor is protected by a robust 6-layer dielectric insulation system. The first layer features high-performance PEF (polyethylene foam tape), offering excellent flexibility, insulation, and thermal resistance, while its internal micro-bubbles enhance shock absorption and reduce vibration. This is followed by a semi-rigid PVC jacket that adds mechanical stability.
Three successive layers of metallic shielding further enhance performance: a thick copper foil wrap, a copper shielding wire composed of 30 strands of 0.18mm wire, and a thick tin-plated copper braided mesh. These three layers provide comprehensive EMI shielding, improve conductivity, and enhance signal purity. The final outer layer is made of green PVC, selected for its durability, UV resistance, and water resistance—ensuring reliable performance even in long-term submerged or outdoor environments.
Backed by over 30 years of expertise in power supply engineering, Monitor Acoustics recognizes the vital role that grounding lines play in the overall system. For users rebuilding or upgrading their power systems, the HU-100M offers unmatched protection, efficiency, and peace of mind.
