Product Highlights

Longitudinal Water Blocking

Underground medium-voltage routes are expensive to access if water enters through local sheath damage and migrates along the cable. NA2XS(F)2Y adds a water-swellable layer around the screened XLPE construction to restrict longitudinal moisture movement. This is particularly valuable on long collector and substation feeders where containing water at the damaged section can reduce the extent of future repair work.

Aluminium MV Collector Feeder

The cable combines a Class 2 aluminium conductor, XLPE insulation, copper-wire metallic screen and PE outer sheath across 6/10 kV to 18/30 kV constructions. That makes it a strong fit for utility PV collector systems, substations and underground distribution networks where long distances make aluminium conductor economy important and the cable still needs a complete screened MV insulation system.

Accessory-Ready Dimensions

Medium-voltage joints and terminations are selected around the cable’s insulation diameter, screen construction and conductor size. NA2XS(F)2Y provides those elements in a defined screened cable design, allowing the approved accessory system to be matched before installation. This supports repeatable jointing and termination work across long MV projects with many identical connection points.

PE Sheath for External Routes

The polyethylene outer sheath is well suited to fixed external, ducted and underground medium-voltage routes where moisture resistance and mechanical durability are important. For sections entering buildings or other locations with defined fire-performance requirements, the sheath and installation system should be selected against the project’s fire specification rather than assuming an external PE construction provides the same fire behaviour as an indoor LSZH cable.

Can you confirm the cable dimensions needed to select NA2XS(F)2Y joints and terminations?

Yes. Once the voltage class and conductor size are fixed, the relevant insulation diameter, screen construction and cable dimensions can be confirmed from the final cable data. The joint or termination manufacturer should then verify that its accessory is suitable for that exact cable construction.

Can you check an equivalent cable from another manufacturer?

Yes. Send the exact cable designation and, where possible, the existing datasheet or project specification. We compare conductor material, construction, voltage rating, standards and the requirements that affect the installation before confirming whether an equivalent can be offered.

What if the required size, core count or construction is not shown on the website?

Send the exact requirement. The website does not represent every possible production combination. We will check whether the construction can be supplied and whether the required standards or certification scope also cover that version before it is quoted.

Can LV and MV cables be supplied in the drum lengths shown in our cable schedule?

Requested drum lengths can be reviewed with the cable schedule. What is practical depends on cable dimensions and weight, total quantity, drum capacity and transport or site-handling limits, so the required lengths should be included with the enquiry.
