1.8/3 (3.6) kV – 12/20 (24) kV Flexible Single Core Buflex SC Cable

1.8/3 (3.6) kV – 12/20 (24) kV Flexible Single Core Buflex SC Cable

Buflex SC Cable is a single-core, medium-voltage flexible power cable with voltage ratings ranging from 1.8/3 (3.6) kV to 12/20 (24) kV. It is widely used in mining equipment, port cranes, and various reel-type and overhead power supply systems. The cable features IEC 60228 Class 5 flexible bare copper conductors and EPR insulation, with a high-performance PUR (polyurethane) outer sheath.

Insulation : EPR
Screen : Copper braid or spinning
Outer sheath : PUR

1.8/3 (3.6) kV – 12/20 (24) kV Flexible Single Core Buflex SC Cable Application

  • Mining and Heavy Equipment: Used to supply power to large-scale open-pit or underground mining equipment such as bucket wheel excavators, scrapers, electric shovels, and drilling rigs, which are often operated in continuous trailing mode.
  • Port and Terminal Lifting Equipment: Used for power connections in high-speed reeling and festoon systems for ship-to-shore cranes (STS), rubber-tired gantry cranes (RTG), rail-mounted gantry cranes (RMG), unloaders, and similar equipment; particularly suitable for coastal environments with high salt fog.
  • Special Applications and Temporary Connections: Used for internal wiring in switchgear with limited space, mobile or containerized substations, and temporary medium-voltage jumper connections in mines and on railways.

1.8/3 (3.6) kV – 12/20 (24) kV Flexible Single Core Buflex SC Cable Technical Data

  • Max. tensile load: 20 N/mm2
  • Reeling speed: up to 60 m/min
  • Max. surface temperature:
  • – fixed installation: – 40 °C up to + 80 °C
  • – mobile operation: – 30 °C up to + 80 °C

1.8/3 (3.6) kV – 12/20 (24) kV Flexible Single Core Buflex SC Cable Feature

  • Ultra-flexible conductor: Utilizes a Class 5 flexible bare copper conductor compliant with the IEC 60228 standard, consisting of a large number of extremely fine copper wires twisted together, which effectively resists metal fatigue caused by repeated bending and coiling.
  • Excellent Chemical Stability: Features resistance to oil, UV radiation, ozone, and moisture, making it suitable for a wide range of indoor and outdoor operating conditions.
  • Comprehensive Shielding System: Includes conductor shielding and an insulating shielding layer, with an outer layer of bare copper braided or wrapped shielding. This not only ensures excellent electromagnetic compatibility (EMC) but also provides a reliable path for fault currents.
