Triplex Service Drop Cable for Single-Phase Three-Wire Service
Triplex service drop cable uses two weather-resistant insulated 1350 aluminium phase conductors twisted around a bare AAC, 6201 aluminium-alloy or ACSR neutral messenger. It is designed for single-phase three-wire overhead secondary and residential service at 600 V phase-to-phase or lower. PE and XLPE phase coverings, alternative messenger groups and established code-name combinations are available for new connections, extensions and replacement sections.
Product Overview
In a triplex assembly, the two covered conductors form the two current-carrying service legs, while the bare neutral completes the circuit and supports the suspended cable. Changing the neutral from AAC to 6201 alloy or ACSR changes strength, mass, conductivity and fitting requirements. The phase covering also affects the temperature basis, thickness and finished diameter used for handling and connections.
Triplex belongs to a single-phase three-wire service arrangement and should not be selected from the number of visible conductors alone. The utility connection diagram, phase and neutral sizes, messenger duty and existing code name determine the correct combination. It differs from duplex two-wire service and from quadruplex three-phase service, so replacement enquiries should identify the complete installed assembly.
Key Features
- Single-phase three-wire arrangement:Two covered 1350 aluminium conductors provide the two current-carrying legs of the specified single-phase, three-wire service, keeping them together as one identifiable overhead assembly.
- Neutral messenger options:AAC, AAAC and ACSR bare neutral messengers offer different combinations of conductivity, mass and tensile capability, allowing the supporting member to suit the route’s mechanical duty.
- PE and XLPE phase covering:PE and XLPE covering options give the phase conductors weather resistance under the temperature basis stated for each product construction, which supports dependable outdoor service.
- Code-name and phase identification:Code names and phase identification connect conductor sizes, neutral family, dimensions and rated strength, simplifying repeat orders and helping crews distinguish the service components during installation.
Product Applications
- Residential single-phase, three-wire service drops from a pole-mounted transformer to the building service head
- Neutral-supported overhead secondary sections serving groups of single-phase consumers within a utility distribution network
- Service replacement and extension work where the existing code name, messenger duty, fittings and installation clearances can be documented

Request the Complete Data Sheet
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
Two aluminium phase conductors are stranded, individually covered with the specified PE or XLPE and identified, then twisted around the selected bare AAC, AAAC or ACSR neutral messenger.
Inspection
Inspection checks both phase conductors, neutral material and stranding, covering thickness and surface, phase identification, finished diameter, rated strength and the tests required by the service-drop schedule.
Packaging
Reels are planned around the service length schedule and cable bend limits, with protection applied to the covered conductors so that handling and transport do not damage their outer surfaces.
Shipping
Each reel records the product code name, phase and neutral configuration, covering, delivery length and production batch, supporting receiving checks and future traceability for the installed service section.
Frequently Asked Questions
Is triplex the correct cable for a residential service?
Triplex is commonly associated with single-phase, three-wire overhead service, but the utility connection diagram remains the deciding reference. Share the voltage, service arrangement and phase size with us; we can match them to the relevant code-name group and prepare the offer around the complete service assembly.
Why are two phase conductors insulated while the neutral is bare?
The two covered conductors carry the two service legs, while the bare neutral completes the circuit and supports the suspended cable. Our quotation will identify each component separately, helping your team review the electrical arrangement, messenger construction and required connection hardware together.
Which messenger material should I select for triplex cable?
AAC, AAAC and ACSR options differ in strength, mass, conductivity, diameter and corrosion behaviour. Provide the span, tensile requirement, neutral duty and fitting preference, and we can present the appropriate corresponding technical rows for your engineer’s comparison rather than selecting from phase size alone.
Can AMPO include service-head connection accessories?
We can include suitable wedges, clamps, lugs or connectors when the conductor materials, sizes and utility connection method are known. Listing them alongside the cable gives you a clearer procurement package and lets both teams check the interfaces before manufacturing and delivery are scheduled.
Can I change an existing PE triplex cable to XLPE?
The two coverings may have different temperature bases, thicknesses and finished dimensions for the selected product construction. Send us the existing code name or data sheet and the new requirement; we can compare the available construction and price the requested option without presenting it as a like-for-like change automatically.
What should be included in a triplex service-drop enquiry?
Please send voltage, service arrangement, phase and neutral sizes, messenger material, PE or XLPE, code name if available, quantity, reel lengths, span details, fittings, destination and required documents. We can organise these points into a complete quotation description for easier technical review.
