        Electra Cables | 10mm Twin Flat TPS Cable 100m | Red and Black Cores

        The 7-135-2RB is a 10mm² twin flat TPS cable with red and black cores in a white PVC sheath, supplied on a 100 metre roll. The 7-135-2RB carries two conductors and no earth core, PVC insulated and PVC sheathed for fixed wiring. Sparky Direct primarily stocks Prysmian and Electra Cables, and an equivalent cable from an alternate reputable brand may be supplied depending on availability.

        Sub-mains and high-load circuits are where conductor size stops being a formality and starts governing whether the installation passes. At 10mm², the conductor cross-sectional area carries current that smaller sizes cannot, and lower resistance per metre keeps voltage drop inside limits across the longer runs these circuits usually involve.

        A 100 metre roll covers a sub-main run in one continuous length, and every joint avoided is one fewer termination to make and one fewer point to fail. The flat profile clips flat against framing and stacks in a tray more predictably than circular cable, and the red and black core identification is visible the moment the sheath is stripped.

        Features

        • 10mm² conductor size — the cross-sectional area that governs current-carrying capacity and voltage drop on the circuit.
        • Twin configuration — two insulated cores, red and black, in a single flat sheath.
        • No earth conductor — this is a twin cable, not twin and earth, so a separate earthing arrangement is required where the installation calls for one.
        • Red and black core colours — the two cores are individually coloured for identification once the sheath is stripped back.
        • PVC insulation and PVC sheath — the standard construction for fixed wiring in Australian residential and commercial installations.
        • Flat profile — sits flat against framing, clips down cleanly, and stacks more predictably in a tray than circular cable.
        • 100 metre continuous roll — covers a full sub-main run without a joint, and suits bulk wiring where offcuts across multiple circuits are expected.
        • White outer sheath — the standard TPS sheath colour for fixed wiring runs.
        • Fixed wiring cable — intended for installed wiring in a building, not for flexible leads, appliance cords, or trailing applications.
        • Brand may vary — Prysmian or Electra Cables is the usual supply, with an equivalent from another reputable brand possible depending on availability.
        • Current rating depends on installation — the capacity of a given cable is set by installation method, grouping, and ambient conditions under AS/NZS 3008, not by conductor size alone.

        Where to use

        • Sub-main runs — feeding a distribution board or sub-board from the main switchboard where 10mm² twin is the specified size.
        • High-load dedicated circuits — circuits where the load or the run length puts smaller conductor sizes out of range.
        • Long runs with voltage drop constraints — the 7-135-2RB reduces voltage drop across distance compared with smaller conductor sizes.
        • Detached structure supply — feeding sheds, garages, and outbuildings where the run is long and the load is substantial.
        • New builds and switchboard upgrades — installations where a continuous 100 metre length covers the sub-main in one pull.
        • Commercial fit-out and rewire — fixed wiring on projects where 10mm² twin appears on the drawings.

        The 7-135-2RB is twin only and carries no earth conductor, so any installation requiring a protective earth needs a separate arrangement. It is a fixed wiring cable and is not for flexible leads, appliance cords, or applications involving movement. Cable selection, current rating, and protection are the licensed electrician's determination under AS/NZS 3000 and AS/NZS 3008 for the specific installation.

        (7-135-2RB)

        It’s commonly used for sub-mains, high-load circuits, and fixed wiring where a heavy-duty twin active/neutral is required.

        The cable includes red and black cores, allowing simple identification of the active and neutral conductors during installation.

        It’s reasonably flexible for its size, allowing smooth routing through wall cavities, ceiling spaces, and switchboard entries.

        Yes, 10mm conductors offer lower resistance, making them suitable for longer runs where voltage drop needs to be minimised.

        Yes, it is manufactured to meet AS/NZS requirements for fixed wiring installations when installed in accordance with local regulations.

        Yes, Sparky Direct supplies the 7-135-2RB in 100m rolls with fast shipping options and secure nationwide delivery.
