Electra Cables | 1.5mm Twin & Earth Flat Cable 450/750V | Purple Non-Migratory PVC Sheath
The Electra Cables SRF3015VHT-100P is a 1.5mm twin and earth flat cable with plain annealed copper conductors, V-90 PVC insulation, and non-migratory V-90 PVC sheath, rated 450/750V. The cable is supplied in 100-metre reels and complies with AS/NZS 5000.2 for Australian wiring standards.
The non-migratory sheath makes the SRF3015VHT-100P suitable for direct contact with polystyrene, ABS, polycarbonate, and acrylic materials—a key advantage in caravans, cold rooms, transportable buildings, and roof insulation installations where cable degradation from plasticiser leaching is a common failure mode. Licensed electricians value this cable for retrofit work in existing installations where alternative routing or protection methods are impractical.
The 1.5mm2 conductor size is a versatile light-to-medium load rating covering general domestic circuits, lighting runs, and accessory circuits in renovation and new-build work. The flat profile (10.0mm × 4.6mm) simplifies routing through wall frames and roof spaces compared to circular cables of equivalent capacity. Sparkies stock the SRF3015VHT-100P for jobs where non-migratory sheath specification is mandatory or where bulk 100-metre reels offer cost savings over smaller cut lengths.
Features
- Non-migratory V-90 PVC sheath — suitable for direct contact with polystyrene and ABS insulation without plasticiser leaching, extending cable service life in caravans, cold rooms, and roof cavities.
- Plain annealed copper conductors — 7-strand 0.5mm construction per AS/NZS 1125, combining mechanical strength with flexibility for off-the-truck installation in tight spaces.
- 450/750V rating — covers general-purpose domestic and light commercial circuits without derating for typical Australian building installations.
- V-90 PVC insulation and sheath — rated for normal operating temperatures from -20°C to +90°C, meeting flame spread and tracking requirements under AS/NZS 5000.2.
- Flat profile (10.0mm × 4.6mm) — reduces profile compared to circular cables, simplifying routing through wall studs and along roof timbers with fewer kinks.
- 100-metre reel supply — single reel covers multiple circuits on a typical residential job, reducing site stocktake overhead compared to smaller cut-length purchases.
- Strips cleanly with standard tools — 0.6mm insulation thickness and 0.9mm sheath thickness provide margin for safe stripping without nicking copper under normal hand-stripping technique.
- Twin and earth configuration — red active, black neutral, and green/yellow earth cores, matching the colour code convention across all residential wiring work.
- Suitable for festoon and temporary wiring — non-migratory sheath also suits outdoor temporary leads and equipment cables in cold storage or outdoor work sites.
- Complies with AS/NZS 5000.2 — Australian wiring standard for flat TPS cables; suitable for use in building internal wiring applications without certification gaps.
Where to use
- Caravan and motorhome wiring — the SRF3015VHT-100P is a direct fit for 12V and 240V circuits in caravans where polystyrene walls create non-migratory cable requirements; 100-metre supply covers the majority of single-axle installs.
- Cold storage and freeze-room installations — sub-zero operating environments accelerate standard cable degradation; the non-migratory sheath extends reliable service life in commercial cold rooms and domestic chest freezers.
- Renovation work with polystyrene insulation — roof cavity rewiring through batts, wall stud drilling through foam blocks, and loft cable runs now require non-migratory specification after safety alerts.
- Transportable buildings and portable structures — temporary and relocatable buildings rely on the SRF3015VHT-100P for circuits routed through prefabricated insulated wall panels.
- General domestic lighting and power circuits — 1.5mm2 is a standard size for final lighting runs, sub-circuits to power points, and accessory circuits in new homes and major renovations.
- Extension leads and temporary outdoor cables — the non-migratory sheath suits temporary site leads and equipment cables in outdoor work, carparks, and renovation sites where cable lies against building materials.
- Retrofit work on existing caravans — upgrading old cable or adding circuits on existing caravans where polystyrene wall linings are already in place.
The SRF3015VHT-100P is not suitable for fixed outdoor installations in fully exposed conditions (UV exposure will degrade the sheath over time), nor for circuits requiring higher conductor capacity—use 2.5mm2 or larger cable for cooker and fixed appliance circuits in kitchen and laundry areas.
