Product Description
Medium Voltage Covered Conductors (MVCC) CCSX CCST Cable
Leading China Aerial MVCC Cable Manufacturer
Medium Voltage Covered Conductors Applications
Medium Voltage Covered Conductors (MVCC) are developed to improve the reliability of the distribution of electricity. Covered conductors consist of a conductor insulated by a covering made of insulating material(s) as protection against accidental contacts with other covered conductors and with grounded parts such as tree branches etc.
Medium Voltage Covered Conductors Construction
Conductor: Stranded non-compacted all aluminum alloy (AAAC) or aluminum conductor steel reinforced (ACSR).
Water Blocking Layer: Extruded, longitudinal water blocking layer (Strippable type, semiconductive, Black).
Conductor Screen: Extruded semi-conductive compound, Black.
Inner Insulation: Extruded cross linked polyethylene (XLPE, Natural).
Outer Insulation: Extruded cross linked polyethylene (UV Stabilized, Tracking & Erosion resistant XLPE, Black).
Medium Voltage Covered Conductors Specifications
• Forest areas – increased reliability if in contact with branches and trees across the phases after storms
• Bird and wildlife protection areas – increased safety
• Plantations – increased reliability if in contact with branches
• Urban areas – reduced footprint due to reduced phase-to-phase distance
• Very cold climates – ice more easily released from the conductor
• Coastal areas – protects the aluminium from corrosion
• Voltage upgrades – reduced phase-to-phase distance allows the use of existing poles and crossarms
