en.Wedoany.com Reported - Spanish cable manufacturer Top Cable unveiled its new Powerflex Ultra cable at Intersolar Europe, a product specifically developed for battery energy storage systems (BESS) applications, with a design focused on installation flexibility and the durability of both the cable and the system.
Due to the high density of cable routing within battery containers, conversion centers, and electrical rooms, flexibility has become a critical factor in energy storage projects. Top Cable states that more flexible cables facilitate installation operations, reduce the required bending radius, and simplify connections between equipment, thereby shortening installation time and lowering on-site labor costs. As the company explained to pv magazine, the cable's flexibility is achieved through improvements in three components: Class 6 conductors offer higher flexibility than the common Class 5 conductors; proprietary technology in the manufacturing process directly affects the flexibility of the insulation layer; and the self-developed sheath material is significantly more flexible than commonly used materials. These three aspects collectively determine the cable's final mechanical performance.
In terms of thermal performance, the Powerflex Ultra cable is designed for continuous operation within a temperature range of -40°C to 90°C. A standout feature is its 30-year service life at an operating temperature of 90°C, a value significantly higher than that of many traditional cables, which are typically designed for continuous operation at a maximum of 70°C. The cable can withstand a short-circuit temperature of 250°C, far exceeding the limit of approximately 160°C for PVC-based cables.
The product meets the UV protection requirements of the EN 50618 standard and can be installed directly in the ground, as well as in conduits, ducts, or in open air, without the need for additional protection. Additionally, it holds an AD8 rating, confirming its capability for permanent underwater operation, which expands installation possibilities in industrial environments, energy infrastructure, or harsh climatic conditions.
In terms of electrical performance, the cable is suitable for low-voltage applications, with an AC rated voltage of 0.6/1 (1.2) kV, and is also available in a 1.8/3 kV AC version, which is fully applicable for 1500 VDC voltages. The product is entirely manufactured in Europe and has obtained certifications from independent bodies such as AENOR, Bureau Veritas, and KEMA-KEUR, along with CE and UKCA markings, allowing it to be sold in the European and UK markets.
