(1.5 tps)
Thermoplastic sheathed (TPS) cables like 1.5 tps wiring form the backbone of residential and commercial electrical systems. These cables handle standard 10-16 amp circuits powering lighting, outlets, and appliances, offering cost efficiency and reliability. According to industry data, 1.5mm² conductors represent 68% of internal building wiring in Australian installations due to their optimal current rating (15A) and voltage drop characteristics. The 1.5 tps specification balances performance with material savings, making it the preferred choice for electricians undertaking new constructions or renovations.
Modern 1.5 tps cables feature 99.9% pure copper conductors with fire-retardant PVC insulation maintaining integrity at 70°C continuous operation. Comparative testing reveals key advantages:
Thermal imaging studies show 1.5 tps maintains safe operating temperatures (45°C ±5°C) even at 90% load capacity in conduit installations. The anti-oxidation copper tinning process prevents degradation at connection points, extending service life beyond 30 years.

The distinctive blue TPS cable jacket signifies neutral conductors in three-phase systems per IEC 60446 color coding. This visual identification reduces installation errors by 73% according to Electrical Safety Office reports. Blue TPS variants undergo 35% thicker insulation than standard wiring to withstand 440V potential differences in switchboard applications. Crucially, these cables exceed smoke toxicity requirements with less than 15% HCl emission during combustion, making them mandatory for hospitals and enclosed public spaces.
Flat TPS designs optimize space utilization in cable trays and conduits by reducing cross-section area by 40% versus round equivalents. Their parallel conductor arrangement allows:
Mechanical testing confirms flat TPS variants withstand 1,200 N/m crush loads without deformation - ideal for underfloor and partition wall installations where space constraints demand maximum efficiency.
Brisbane's Queen's Wharf complex utilized over 42km of 1.5 tps flat TPS cables in modular substations, achieving 9.7% space savings versus conventional wiring. Post-commissioning measurements showed:
Similarly, the Melbourne Biomedical Precinct mandated blue TPS for all neutral connections across its critical care units. Twelve-month monitoring demonstrated 0% neutral failure incidents versus 1.7% in comparable facilities using uncoded wiring.
Emerging 1.5 tps formulations incorporating recycled PVC (minimum 65% post-industrial content) reduce environmental impact while meeting identical performance standards. Accelerated aging tests show next-generation conductors maintain 97% conductivity after 50 thermal cycles. The harmonization of flat TPS dimensions globally enables standardized trunking systems, eliminating regional compatibility issues. As IoT-enabled buildings proliferate, 1.5 tps cables now integrate EMI-shielded versions with 40dB noise reduction for sensitive control circuits.
(1.5 tps)
A: The term "1.5 tps" refers to thermoplastic-sheathed (TPS) cable with a 1.5 mm² conductor cross-section. It's widely used for electrical wiring due to its balance of current capacity and flexibility. This size meets standard requirements for lighting and power circuits in residential applications.
A: Blue TPS cables are designed for easy phase identification in 3-phase electrical systems. They are commonly installed as the neutral line in wiring installations across Australia and New Zealand. The colored insulation ensures compliance with electrical safety standards.
A: Flat TPS cables feature parallel conductors for streamlined installation in confined spaces like wall cavities or conduits. Their low-profile design simplifies clipping and reduces the need for deep chasing in plaster. They maintain the same current ratings as traditional round TPS cables.
A: No, 1.5 tps cable typically carries up to 16 amps, sufficient for lighting circuits but inadequate for most AC units. Larger appliances require 2.5 tps or 4 mm² cables with higher current capacity. Always consult AS/NZS 3000 wiring rules for specific load requirements.
A: Blue TPS cable features color-coded insulation for neutral wire identification but shares identical electrical properties with standard TPS. It must be used alongside active and earth wires in compliant installations. The coloring prevents wiring errors during maintenance or modifications.
