Versatile Medium-Voltage Branch Connector for 24 kV Cable Systems
The CB 24-250 L is a high-performance branch connector designed for use in medium-voltage cable systems up to 24 kV. Engineered for compatibility with voltage sensors or insulating plugs, this connector enables safe and efficient connections between plastic-insulated cables and switchgear or transformers equipped with Type A (250 A) bushings in accordance with EN 50180 and EN 50181.
  • Dual FunctionalityAvailable with either a voltage sensor or an insulating plug, the CB 24-250 L supports both monitoring and standard connection applications.
  • Wide Conductor RangeAccommodates conductor cross-sections from 25 mm² to 300 mm², making it suitable for a broad range of cable sizes and installation scenarios.
  • Quick and Easy AssemblyDesigned for fast installation, the connector includes all necessary components and clear assembly instructions, reducing downtime and labor costs.
  • Integrated Stress ControlEach unit includes a stress cone to ensure optimal electric field distribution and minimize the risk of partial discharges.
  • Shielded DesignFeatures an outer conductive layer for effective electromagnetic shielding and enhanced operational safety.
  • Maximum System Voltage: 12.7/22(24) kV
  • Partial Discharge: < 5 pC
  • AC Withstand Voltage (5 min): 57 kV
  • Impulse Withstand Voltage: 125 kV
  • Core Insulation Diameter Range: 12.7 mm to 34.6 mm (depending on variant)
  • Conductor Cross-Section Options:
    • 25–95 mm²
    • 95–240 mm²
    • 95–300 mm²
Each CB 24-250 L kit includes:
  • Cable Connector Body
  • Stress Cones (3 pcs)
  • Conductor Cable Lugs (3 pcs)
  • Earthing Cable Lugs (3 pcs)
  • Assembly Instructions
  • Accessories for complete installation
Packaged for convenience and protection, the CB 24-250 L is ready for deployment by certified installers in both onshore and offshore environments.
Ideal for:
  • Medium-voltage switchgear
  • Transformer connections
  • Smart grid voltage monitoring
  • Industrial and utility power distribution
Whether you're integrating voltage sensors or simply branching cables, the CB 24-250 L offers the flexibility, safety, and performance required for modern electrical infrastructure.
