Flexible 1500 V DC cable for fixed connections between battery racks, combiner equipment and power conversion systems.
Battery racks, combiner equipment and PCS connections concentrate high DC current in limited enclosure space. ESS DC Cable uses a fine-stranded tinned-copper conductor to make fixed high-current links easier to route without forcing the cable against busbars or terminals. The broad 1.5 to 400 mm² range lets the same cable family cover small internal connections and large DC feeders within the storage system.
Battery containers and power-conversion cabinets place many power cables in a confined environment where fire behaviour matters. Electron-beam cross-linked halogen-free insulation and sheath materials reduce flame propagation, smoke density and corrosive gas generation compared with conventional halogen-containing constructions. This supports a fire-conscious cable strategy inside ESS equipment while retaining the electrical insulation required for high-voltage DC service.
The cross-linked insulation and sheath system is designed for fixed service from -40°C to +120°C and provides resistance to UV, ozone, weather, oils, fuels, alkalis and acids. These properties are valuable where ESS cables pass through battery cabinets, container floors or outdoor equipment and experience heat, condensation and industrial contamination. The tinned Class 5 conductor also supports reliable flexible routing in these exposed storage-system environments.
Designed for Battery racks, ESS containers, Power conversion systems and Fixed storage plant cabling.

Where a certificate, test report or DoP is part of the approval package, we match it to the quoted cable construction and the applicable scope. A document for one version is not treated as approval for another simply because the model name is similar.
No. ESS DC is an application and product-family description rather than a standardised cable designation. The current construction uses a 1.5 kV DC design with Class 5 tinned copper and cross-linked halogen-free compounds, with EN 50618 used as a design basis. It should not be treated as H1Z2Z2-K or as EN 50618 certified unless the issued product documents specifically state that.
No CPR class is currently stated for the ESS DC Cable. Halogen-free or flame-retardant performance does not by itself establish a CPR classification. If CPR is required for the project, the exact cable construction and supporting documentation must be confirmed before quotation.
We need the connection point, such as rack-to-combiner or combiner-to-PCS, together with DC voltage, operating current or required conductor size, route length and installation conditions. Terminal drawings or available connection space are useful where large conductor sizes are involved.
This can be reviewed once the conductor size, finished length and termination are defined. Send the required lug or terminal part number, drawing or connection dimensions and confirm whether the assembly is single-ended or double-ended. The finished assembly specification is confirmed separately from the bulk cable.
