High Voltage 2XS(FL)2Y Cable
2XS(FL)2Y Cable is a single-core high-voltage power cable with a copper conductor, Изоляция из сшитого полиэтилена, metallic screen, 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) кВ, 36/60 (72.5) кВ, 64/110 (123) кВ и 76/132 (145) кВ.
XWA supplies project-configured 2XS(FL)2Y high-voltage cable according to the confirmed voltage class, размер проводника, screen section, материал оболочки, 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, радиус изгиба, 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.
Для туннелей, 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(Ф)2Y
2XS(FL)2Y and A2XS(FL)2Y share the same high-voltage water-blocked cable logic, но материал проводника другой. 2XS(FL)2Y uses copper, while A2XS(FL)2Y uses aluminium.
2XS(Ф)2Y is not the same as 2XS(FL)2Y. The `(Ф)` 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.
| Модель | Основное отличие | Page role |
|---|---|---|
| 2XS(FL)2Y | Медный проводник, СПЭ, water-blocked screen area, laminated radial barrier, PE sheath | Эта страница |
| A2XS(FL)2Y | Aluminium conductor version | Next companion HV page |
| 2XS(Ф)2Y | Copper conductor with longitudinal water blocking, without the same FL radial-barrier meaning | Separate water-blocked variant |
| 2XS(FL)ЧАС | LSZH outer sheath direction | Indoor or low-smoke route comparison |
Тестирование, Документы и экспортная упаковка
High-voltage 2XS(FL)2Y cable documentation can include the approved datasheet, conductor resistance record, voltage test record, partial-discharge test record, sheath test, проверка размеров, расписание барабанов, упаковочный лист и фотографии товара.
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, максимальный диаметр барабана, transport route, lifting method and container loading limit. Large-section 110 кВ и 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?
Общие классы проектного напряжения включают: 26/45 (52) кВ, 36/60 (72.5) кВ, 64/110 (123) кВ и 76/132 (145) кВ. 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, аксессуары, 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, масса, size selection, termination design and short-circuit performance.
What is the difference between 2XS(FL)2Y and 2XS(Ф)2Y?
2XS(Ф)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, подстанции, 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?
МЭК 60840 is the common reference for extruded-insulation power cables above 30 kV and up to 150 кВ. МЭК 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, размер проводника, screen section, материал оболочки, route condition, стандартный, количество, длина барабана, destination country and required test documents.
