Top Cable Unveils Powerflex Ultra Flexible Cable for Battery Storage Projects
In June 2026, Spanish cable manufacturer Top Cable introduced Powerflex Ultra, a new flexible cable specifically designed for battery energy storage system (BESS) applications, at Intersolar Europe .
The product was developed to address two key requirements in storage projects: installation flexibility and long-term durability. Battery containers, power conversion stations, and electrical rooms typically contain high cable densities, making flexibility an important consideration during installation .
Key Technical Specifications:

Conductor | Class 6 (high flexibility) |
Operating Temperature | -40°C to +90°C |
Service Life | 30 years at 90°C |
Short-Circuit Temperature | Up to 250°C |
Voltage Rating | 0.6/1 (1.2) kV AC, 1.8/3 kV AC |
DC Compatibility | 1,500 V DC |
Water Resistance | AD8 (permanent submersion) |
The cable combines a proprietary insulation manufacturing process and a custom-developed sheath material to improve flexibility compared with conventional products, reducing bending radii, simplifying equipment connections, and lowering installation time and labor requirements .
Powerflex Ultra meets UV protection requirements under EN 50618 and can be installed directly underground, in ducts, or outdoors without additional protection. It carries certifications from AENOR, Bureau Veritas, and KEMA-KEUR, in addition to CE and UKCA markings .
