NFA2X Aluminium Aerial Bundled Cable
NFA2X aerial bundled cable uses stranded aluminium conductors with XLPE insulation for low-voltage overhead distribution, service circuits and public lighting. Available designs cover HRN HD 626, DIN VDE and SPLN requirements, including core combinations with an aluminium-alloy supporting neutral and NFA2X-T arrangements with an AAAC or ACSR neutral messenger. Conductor size, complete core formula, support member and identification are selected for the applicable utility network.
Product Overview
The NFA2X designation does not define one universal support arrangement across every market. HRN HD 626 and DIN VDE designs may include an aluminium-alloy supporting neutral, while the referenced SPLN NFA2X-T configuration uses an AAAC or ACSR neutral messenger. Some configurations also include one or more public-lighting cores. These differences change bundle mass, sag behaviour, tensile duty and the clamps required for suspension and anchoring.
Product selection must therefore follow the governing utility specification rather than the suffix alone. Buyers should identify the voltage, complete core arrangement, phase and neutral sizes, messenger material, span duty and connection method. NFA2X uses aluminium current-carrying conductors and should be kept separate from NF2X copper bundles, which have different resistance, mass and connection requirements even when the nominal conductor area is similar.
Key Features
- Aluminium phase conductors:Stranded aluminium phase conductors provide the required electrical path with comparatively low bundle mass, helping crews handle and string low-voltage overhead circuits across established pole routes.
- XLPE insulation:Extruded XLPE forms a weather-resistant insulating layer around each live core; its specified thickness separates conductors within the twisted bundle and supports outdoor electrical service.
- Supporting-conductor options:HRN HD 626 or DIN VDE designs may use an aluminium-alloy supporting neutral, while the referenced SPLN NFA2X-T construction uses an AAAC or ACSR neutral messenger.
- Core formulas and identification:Available core formulas can combine phase, neutral and public-lighting conductors, so one bundle can serve the circuit arrangement shown in the utility schedule while preserving clear core identification.
Product Applications
- Low-voltage aluminium distribution between poles in urban, village and rural networks governed by an NFA2X construction
- Street-lighting routes that require identified lighting cores within a self-supporting or neutral-supported aerial bundle
- Overhead service extensions and network renewal where messenger material, span duty and pole hardware are coordinated with NFA2X-T

From Production to Delivery
From raw material preparation to final shipmen, every stage is caretuly controled to ensure consistent conductor quality, reliable pertormance,and sae delivery. Our roduction,
inspection, packaging, and logistics processes are managed in accordance with applicable standards and project requirements.
Production
Aluminium wires are stranded to the scheduled conductor size, individual cores receive their specified XLPE insulation and identification, and the cores are twisted into the NFA2X or NFA2X-T arrangement shown in the order.
Inspection
Quality checks cover conductor cross-section and resistance, insulation thickness and surface, core marking, bundle lay, finished diameter and the electrical or mechanical tests required by the relevant HD, DIN VDE or SPLN schedule.
Packaging
Reel dimensions and delivery lengths are selected with the finished bundle diameter, bending limits, handling equipment and route plan in mind, while end protection helps keep moisture and contamination away from the cores.
Shipping
Shipping records state the NFA2X or NFA2X-T designation, full core formula, messenger type, standard, reel length and batch, giving the site team a clear reference for receiving and installation control.
Frequently Asked Questions
How do I know which NFA2X construction I need?
Selection should follow the governing utility specification, standard or network drawing. Different NFA2X designs use different supporting arrangements, while the referenced SPLN NFA2X-T construction uses an AAAC or ACSR neutral messenger. Send the complete core formula, voltage and span information, and we will organise the quotation around that exact configuration.
Can you help compare HD 626, DIN VDE and SPLN constructions?
We can set the relevant tables side by side and highlight differences in conductor form, insulation thickness, core formula, messenger and finished dimensions. The quotation will follow the standard and edition you specify, so a similar nominal cross-section is not allowed to obscure a different cable construction.
I need public lighting as well as distribution. What should I specify?
Please state the number and size of phase, neutral and lighting cores, together with the identification method required by the utility. We will reproduce the complete requested arrangement in the offer and can include suitable connection accessories where enough installation information is available.
Which neutral messenger should I choose for NFA2X-T?
The choice depends on the messenger options in the applicable schedule and on span, tensile duty, mass, corrosion conditions and fittings. Provide those project details and we can point you to the relevant AAAC or ACSR technical specification group for engineering review and commercial comparison.
Can the required clamps and connectors be supplied with the cable?
Compatible suspension, dead-end and insulation-piercing connection products can be considered as part of the enquiry. We will need the conductor sizes, messenger construction, finished bundle dimensions and pole arrangement to narrow the accessory range and avoid offering hardware for a different support concept.
What information will help you return an NFA2X quotation quickly?
Send the voltage, standard and edition, NFA2X or NFA2X-T designation, complete core formula, messenger material, quantity, reel lengths, accessories, destination and inspection requirements. If you only have a utility schedule or drawing, we can use it to organise the missing commercial and technical details.
