This Medium Voltage Cable and AWA Armoured Cable category is specialized exclusively for high-capacity, single-core alternating current (AC) main transformer links and primary substation connections. By implementing high-conductivity, non-magnetic aluminium wire armour (AWA), this high-ampacity series isolates alternating electromagnetic fields to deliver maximum electrical system efficiency without inductive eddy current heating.
·Standards: IEC 60502-2
·Cores: 1 Core Only (Note: This section holds 1-Core cables exclusively; for multi-phase 3-Core projects, please view our STA / SWA armoured catalogs)
·Conductors & Screening: Premium Copper (CU) or Aluminum (AL) cores supported by precision CTS or CWS moisture-sealed shielding.
·Material Matrix: Formulated with premium 90°C XLPE insulation over single-core conductors. The outer protective jacket can be freely customized with PE or PVC compounds to fight aggressive environmental aging or high-salinity exposure.
·Optional Upgrade: To combat severe environmental aging in coastal or high-humidity zones, the aluminum armor grid can be reinforced with optional moisture-blocked swelling tapes or specialized UV-stabilized jackets to prevent galvanic corrosion.
Key Advantages
·Eliminate Inductive Loop Overheating: Traditional steel wires act as a magnetic choke on single cores. Our non-magnetic AWA structure completely avoids eddy current bottlenecks, ensuring zero loop power waste, cool-running performance, and maximum continuous grid capacity.
·Rigging Weight Reduction: The lightweight profile of aluminum wires heavily cuts down total cable self-weight compared to steel wire alternatives, drastically lowering installation rigging tension, handling strain, and crane logistics expenses for heavy cross-section lines.
·Corrosion-Protected Armor Shell: While maintaining excellent thermal dissipation, the aluminum cage creates a tough mechanical barrier against soil compaction and underground pests, with optional upgrades available for marine or coastal mist resistance.
Application Guideline
·Choose AWA: Mandated for generator-to-transformer links, high-power heavy industrial smelters, utility substation bays, and coastal or offshore energy grids.
·Alternatives: Ferrous STA and SWA are strictly unsuited for high-current single-core AC routes. For multi-phase configurations requiring underground armoring, refer to our 3-Core STA or SWA portfolios.
Zhongdong Cable combines premium raw materials, large-scale manufacturing capabilities, and strict quality control systems to deliver cable products that fully match your technical requirements and brand identity.
