FAQ & Support

Is ESS DC Cable a standard cable designation such as H1Z2Z2-K?

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.

Can NYY, N2XY and N2XH be treated as direct alternatives?

No. They can share the same 0.6/1 kV voltage class, but their insulation, sheath materials, fire behaviour and intended installation conditions differ. The required cable should follow the route and fire specification rather than the voltage rating alone.

Can you match the PV connector system already used on our project?

Send the exact connector manufacturer and model together with the cable size. Current PV extension options include Stäubli Original MC4 and MC4-EVO 2. Compatibility is checked against the actual connector system; appearance or a general “MC4-compatible” description is not enough.

Can MMJ replace NYM, or vice versa?

Not automatically. MMJ is specified in the Finnish market under SFS 2091, while NYM belongs to a different product and standards environment. The project specification, core arrangement, installation method and fire requirement should be checked before either cable is proposed as a substitute.

Does the current ESS DC Cable have a CPR classification?

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.

Can you propose an aluminium alternative to a copper LV cable in our BOQ?

Yes, this can be reviewed, but aluminium is not normally a size-for-size replacement for copper. Current, route length, voltage drop, installation method, available space and the equipment termination system all need to be checked before an alternative size is proposed.
