What is 2-Core TPS Cable?
- Conductor: High-quality annealed copper for excellent conductivity.
- Insulation: Each core is individually insulated with colour-coded thermoplastic PVC (e.g., Red/Brown for Active, Black/Blue for Neutral).
- Sheath: A tough white or grey PVC outer sheath that binds the two insulated cores side-by-side in a flat formation.
Key Features of 2-Core TPS Cable
- High Safety: Compliant with Australian/New Zealand Standard (AS/NZS 5000.2), it offers excellent insulation and flame-retardant properties, minimizing risks of short circuits and fires.
- Superior Durability: The robust sheath provides excellent resistance to abrasion, impact, moisture, and chemicals, suited for the demanding environment inside a caravan.
- Good Flexibility: While designed for fixed wiring, it retains sufficient flexibility for easy pulling and routing through caravan frames and conduits.
- Ease of Installation: The flat design simplifies securing and identification during installation.
- Clear Certification: Compliant TPS cables are marked with clear certification logos (e.g., SAA), ensuring easy verification.
Why TPS Cable is Mandatory for Australian Caravan Wiring?
- Regulations & Safety Standards: Australia has strict regulations for electrical installations in caravans and RVs, mandating the use of products compliant with AS/NZS 3001. TPS cable is the specified type that meets this standard. Using non-compliant cable is illegal and poses a significant safety hazard.
- Suitability for Caravan Environment: Caravans experience constant vibration during travel and endure temperature fluctuations and humidity when parked. The robust construction and durability of TPS cable withstand these challenges, ensuring long-term reliability of the electrical system.
- Insurance and Warranty Prerequisite: In the event of an accident caused by non-standard cabling, insurance claims may be void. Furthermore, caravan manufacturers require the use of compliant cables to uphold the vehicle’s warranty.
Key Considerations When Selecting Compliant TPS Cable
- Verify Standard Compliance: Check the cable sheath for clear printing indicating compliance with AS/NZS 5000.2.
- Inspect Markings: Compliant cables will be marked with the manufacturer’s name, cable type, voltage rating (e.g., 450/750V), and conductor size (e.g., 2×1.5mm²).
- Choose a Reliable Supplier: Purchase from reputable manufacturers or authorized distributors like JZD Cable to guarantee product authenticity.
- Select the Correct Size: Choose the appropriate conductor cross-sectional area (e.g., 1.5mm² or 2.5mm²) based on the current-carrying capacity required by your caravan’s electrical appliances.
