High Voltage 2XS(FL)2Y Cable
2XS(FL)2Y Cable is a single-core high-voltage power cable with a copper conductor, Isolamento XLPE, schermo metallico, longitudinal and radial water-blocking layers, and a polyethylene outer sheath.
The designation is used for underground and ducted high-voltage distribution and transmission routes where IEC 60840-type construction, water blocking and PE sheath performance are part of the project specification. Common voltage classes include 26/45 (52) kV, 36/60 (72.5) kV, 64/110 (123) kV and 76/132 (145) kV.
XWA supplies project-configured 2XS(FL)2Y high-voltage cable according to the confirmed voltage class, dimensione del conduttore, screen section, materiale della guaina, test requirement, drum length and export documentation scope.

2XS(FL)2Y Cable Construction
2XS(FL)2Y uses a copper conductor with an extruded conductor screen, XLPE insulation and extruded insulation screen. The metallic screen uses copper wires and an equalising tape, with semiconductive water-swelling tape placed around the screen area.
The `(FL)` part is the key distinction from simpler PE-sheathed HV cable. It indicates a water-blocked design with longitudinal water blocking and a radial barrier formed by an aluminium copolymer laminated tape bonded to the polyethylene sheath.
This construction is normally single-core. Three-core high-voltage cable is not treated as the standard form for this designation because electrical stress control, raggio di curvatura, screen bonding and installation handling are different.
Applications for 2XS(FL)2Y High Voltage Cable
2XS(FL)2Y Cable is used in buried high-voltage networks, duct routes, substation connections, renewable-energy grid connections, industrial incoming feeders and utility transmission circuits where PE-sheathed water-blocked HV cable is specified.
The design is especially relevant where moisture exposure, long underground routes, joint bays and sheath integrity are important parts of the cable system. Cable accessories, bonding design and route thermal calculation remain part of the complete HV system design.
For tunnels, indoor termination sections or routes requiring low-smoke zero-halogen sheath behaviour, the related `2XS(FL)H` construction may be reviewed instead of a PE-sheathed `2Y` design.
2XS(FL)2Y vs A2XS(FL)2Y and 2XS(F)2Y
2XS(FL)2Y and A2XS(FL)2Y share the same high-voltage water-blocked cable logic, but the conductor material is different. 2XS(FL)2Y uses copper, while A2XS(FL)2Y uses aluminium.
2XS(F)2Y is not the same as 2XS(FL)2Y. The `(F)` designation is associated with longitudinal water blocking, while `(FL)` adds the laminated radial barrier concept. This difference matters for wet underground routes and sheath-damage risk.
N2XS2Y and N2XSY pages remain medium-voltage designations. The 2XS(FL)2Y page targets high-voltage IEC 60840-type project intent and should not compete with the medium-voltage cluster.
| Modello | Main distinction | Page role |
|---|---|---|
| 2XS(FL)2Y | Conduttore in rame, XLPE, water-blocked screen area, laminated radial barrier, PE sheath | This page |
| A2XS(FL)2Y | Aluminium conductor version | Next companion HV page |
| 2XS(F)2Y | Copper conductor with longitudinal water blocking, without the same FL radial-barrier meaning | Separate water-blocked variant |
| 2XS(FL)H | LSZH outer sheath direction | Indoor or low-smoke route comparison |
Test, Documents and Export Packing
High-voltage 2XS(FL)2Y cable documentation can include the approved datasheet, conductor resistance record, voltage test record, partial-discharge test record, prova guaina, dimensional inspection, drum schedule, packing list and product photos.
Type-test evidence, third-party inspection and project-specific test documentation are handled according to the exact voltage class, cable construction and contract requirement. No third-party certification, grid approval or project reference is implied unless separately verified.
Export packing is planned by cable weight, maximum drum diameter, transport route, lifting method and container loading limit. Large-section 110 kV and 132 kV single-core cables require drum-length planning before production.
2XS(FL)2Y Cable FAQs
What is 2XS(FL)2Y Cable?
2XS(FL)2Y Cable is a single-core copper-conductor high-voltage XLPE cable with metallic screen, longitudinal water blocking, laminated radial water barrier and polyethylene outer sheath. It is used for fixed HV underground and ducted cable systems.
What voltage classes are common for 2XS(FL)2Y Cable?
Common project voltage classes include 26/45 (52) kV, 36/60 (72.5) kV, 64/110 (123) kV and 76/132 (145) kV. The project specification defines the exact Uo/U and Um rating.
What does FL mean in 2XS(FL)2Y Cable?
The `(FL)` element indicates water-blocking construction with longitudinal water-blocking layers and a laminated radial barrier bonded to the polyethylene sheath. It is a key distinction from simpler PE-sheathed HV cable.
Is 2XS(FL)2Y a single-core or three-core cable?
2XS(FL)2Y is normally a single-core HV cable. Three-core high-voltage designs require a separate review because the construction, accessori, installation handling and electrical design are different.
What is the difference between 2XS(FL)2Y and A2XS(FL)2Y?
2XS(FL)2Y uses a copper conductor. A2XS(FL)2Y uses an aluminium conductor. The conductor material changes resistance, peso, size selection, termination design and short-circuit performance.
What is the difference between 2XS(FL)2Y and 2XS(F)2Y?
2XS(F)2Y is associated with longitudinal water blocking. 2XS(FL)2Y adds the laminated radial barrier concept, so the two designations should not be treated as interchangeable in wet underground routes.
Where is 2XS(FL)2Y Cable used?
2XS(FL)2Y is used in underground high-voltage feeders, utility grids, sottostazioni, renewable-energy grid connections, industrial incoming supplies and ducted transmission routes where water-blocked PE-sheathed HV cable is specified.
What standards are used for 2XS(FL)2Y Cable?
CEI 60840 is the common reference for extruded-insulation power cables above 30 kV and up to 150 kV. CEI 60228 is commonly used for conductor class reference. Standard mention does not mean third-party certification or grid approval.
Can 2XS(FL)2Y Cable be supplied with MDPE or HDPE sheath?
HDPE and MDPE sheath directions are both used in project specifications. The sheath choice depends on route conditions, mechanical exposure, installation handling and the approved datasheet.
What information is needed for a 2XS(FL)2Y Cable quotation?
XWA confirms 2XS(FL)2Y Cable based on voltage class, dimensione del conduttore, screen section, materiale della guaina, route condition, standard, quantità, lunghezza del tamburo, destination country and required test documents.
