Key Technical Parameters | Parámetros Técnicos | 關鍵技術參數
Product Overview
The 15kV AL Compact NL-EPR 133% Insulation Level AIA MV-105 Power Cable represents a premium-grade medium voltage power distribution cable engineered for demanding utility and industrial applications. This three-conductor aluminum cable features 220 mils of No Lead Ethylene Propylene Rubber (NL-EPR) insulation at the 133% insulation level, copper tape shielding, aluminum interlocked armor (AIA), and a distinctive red PVC overall jacket for easy identification in the field.
The 133% insulation level designation per ICEA S-93-639 (NEMA WC 74) indicates this cable is designed for systems where the fault-clearing time is indefinite or where ground fault relaying is not employed. This provides enhanced reliability and safety margins for critical power distribution infrastructure. The MV-105 rating confirms continuous operation at 105°C conductor temperature with emergency overload capability to 140°C and short-circuit withstand to 250°C.
Purpose and Applications
This medium voltage cable is specifically designed for primary power distribution in utility and industrial environments where reliability, mechanical protection, and environmental resistance are paramount. Per UL 1072 and ICEA S-93-639, approved applications include:
Key Characteristics and Material Advantages
The NL-EPR (No Lead Ethylene Propylene Rubber) insulation system represents state-of-the-art medium voltage cable technology. Unlike traditional EPR compounds that may contain lead-based stabilizers, NL-EPR utilizes environmentally-friendly stabilizer systems while maintaining excellent dielectric properties, thermal stability, and moisture resistance. The 220 mil insulation wall thickness at 133% level provides significant safety margins for ungrounded or high-resistance grounded systems.
The 8000 Series Aluminum Alloy conductor (AA-8176) per ASTM B800 and ASTM B836 offers superior creep resistance and connection stability compared to traditional AA-1350 aluminum. The compact stranded Class B construction reduces overall cable diameter while maintaining current-carrying capacity, enabling easier installation in existing conduit systems. The conductor’s lighter weight (approximately 50% of equivalent copper) significantly reduces installation costs and structural loading in overhead installations.
The copper tape shield system consists of helically-wrapped 5 mil copper tape with 25% overlap, providing consistent electrostatic shielding and a reliable fault current return path. The strippable semi-conducting insulation shield allows clean, efficient termination and splicing without damaging the primary insulation. The aluminum interlocked armor provides continuous mechanical protection while allowing flexibility for installation around bends without additional fittings.
