CB 24-250
Engineered for excellence in medium-voltage branch connections
The CB 24-250 Branch Connector is a compact and high-performance solution designed for the safe and efficient branching of 24 kV polymeric cables. Built to meet the rigorous demands of modern power distribution systems, this connector combines robust materials, precise engineering, and user-friendly features to ensure long-term reliability in both onshore and offshore environments.
Key features
Flexible cable compatibilityThe CB 24-250 supports copper and aluminum conductors ranging from 35 mm² to 400 mm², and is compatible with RM, RE, and class 5 conductor types. It accommodates insulation diameters from 12.7 mm to 34.6 mm, making it suitable for a wide range of medium-voltage cable systems.
Reliable electrical performance Tested according to HD 629.1 standards, the CB 24-250 delivers dependable performance under demanding conditions:
- AC withstand voltage: 57 kV (5 minutes)
- Impulse withstand voltage: 125 kV
- Partial discharge: < 10 pC at 25 kV
- Rated voltage: 24 kV
- Highest voltage (phase-to-phase): 22 kV
- Design voltage to ground: 12.7 kV
Compact and durable design With a length of approximately 290 mm and a weight of just 0.7 kg, the CB 24-250 is easy to handle and install. Its pre-molded silicone rubber body, produced via precision injection molding, ensures excellent mechanical strength and environmental resistance.
Short-circuit resilience Engineered to withstand:
- Thermal short-circuit current (1s): 8.5 kA at 35 mm² Cu
- Maximum continuous current: 250 A
Material and construction
The CB 24-250 features a geometrically pre-molded silicone rubber housing that provides superior insulation and stress control. Its robust construction ensures long-term performance in harsh environments.
Scope of delivery
Each CB 24-250 kit includes:
- Pre-molded silicone rubber connector body
- Compression or mechanical shear bolt connectors
- Insulating plug
- All required accessories for installation
- Clear assembly instructions
Applications
Ideal for medium-voltage cable branching in:
- Utility distribution networks
- Industrial installations
- Offshore platforms and substations
- Infrastructure requiring compact and reliable branching solutions
Installation and storage
- Installation temperature: –5°C to +50°C
- Storage temperature: +5°C to +40°C (dry, max. 60% RH, non-condensing)
- Expected service life: 40 years
- Installation height: Not limited
- Protection: Rain and dust protected; certified fitters recommended
