ALUMINUM MV-105 15kV-35kV

Aluminum MV-105 (15kV–35kV) is a heavy-duty medium-voltage cable used for primary power distribution in industrial plants and utility grids. Its "105" rating means it can safely operate at higher temperatures (105°C) than standard cables, allowing it to carry more current. It is engineered for durability in conduits, underground ducts, or direct burial, making it the standard for high-voltage reliability. Read our Aluminum MV-105 15kV-35kV Buyers Guide.

ALUMINUM MV-105 MEDIUM VOLTAGE CABLE (15kV–35kV)

Aluminum MV-105 is a high-performance, shielded power cable designed for primary distribution in commercial, industrial, and utility applications. Rated for 15kV, 25kV, and 35kV, this cable is specifically engineered to operate at a continuous conductor temperature of 105°C, providing higher ampacity and a greater safety margin than standard 90°C cables. The construction features a 1350-H19 aluminum conductor, a semi-conducting shield, and Tree-Retardant Cross-Linked Polyethylene (TR-XLPE) or EPR insulation. A copper tape shield is applied over the insulation to provide 100% coverage for electromagnetic interference (EMI) protection and to facilitate grounding. Encased in a flame-retardant PVC jacket, MV-105 is UL-listed for use in cable trays (TC-ER), conduits, and direct burial applications.

Installation Note: Because MV-105 features a copper tape shield, special care must be taken during the "stripping" process to avoid nicking the underlying semi-con layer. Proper grounding of the copper tape at both ends (or one end, depending on engineering specs) is mandatory to drain capacitive charging currents. When installing in cable trays, ensure the minimum bending radius—typically 12 times the overall cable diameter—is strictly maintained to prevent stress on the tape shield and insulation.

Key Features
  • 105°C Temperature Rating: Certified for a higher continuous operating temperature, allowing for increased power loads and improved emergency overload performance.
  • 5-mil Copper Tape Shield: Features a helically applied copper tape with a 12.5% minimum overlap, ensuring effective grounding and electrostatic shielding.
  • TR-XLPE or EPR Insulation: Utilizes high-dielectric materials that resist "water treeing" and electrical breakdown in high-stress environments.
  • Flame-Retardant PVC Jacket: The outer jacket is sunlight-resistant and formulated to resist oil, chemicals, and the spread of fire.
  • Tray Cable (TC-ER) Rated: Many sizes are rated for use in cable trays and as "Exposed Run," allowing for cost-effective industrial installations without continuous conduit.
  • Triple-Extruded Shielding: The conductor shield, insulation, and insulation shield are extruded in a single pass to eliminate contaminants and air voids.
  • Industry Standards: Manufactured to meet UL 1072, AEIC CS8, and ICEA S-93-639 standards for medium-voltage power cables.
Common Applications
  • Industrial Plant Power: The primary choice for 15kV–35kV feeders in manufacturing facilities, paper mills, and steel plants.
  • Petrochemical & Refineries: Ideal for power distribution in environments where resistance to chemicals and high thermal stability is required.
  • Substation Secondary Runs: Used to route power from primary transformers to industrial distribution switchgear.
  • Commercial High-Rise Distribution: Providing high-voltage vertical feeders for large-scale urban infrastructure and data centers.
  • Wastewater Treatment Plants: Durable enough for the moist, corrosive environments typical of municipal utility facilities.
  • Mining Operations: Used in surface mining applications where a rugged, tray-rated medium-voltage cable is necessary.
  • Renewable Energy Collection: Connecting wind turbines or solar combiner stations to the main collector substation.
