AS/NZS 1125 Armoured Control Cable 0.6/1kV
AS/NZS 1125 Armoured Control Cable is a 0.6/1kV multicore-plus-earth control cable using plain annealed copper conductors in stranded constructions selected for reliable electrical performance in commercial, industrial, mining and utility control circuits. The available range uses 1.5 mm² conductors in 7/0.50 mm construction and 2.5 mm² conductors in 7/0.67 mm construction, combined with PVC V-90 insulation, PVC bedding, galvanised steel wire armour and PVC 5V-90 outer sheath. With conductor resistance, core identification and multicore assembly controlled as part of the finished cable design, the product is suitable for fixed installations where both dependable control-circuit performance and mechanical protection are required.
Conductor Construction
The conductor is the electrical core of the cable and directly influences resistance, voltage drop and current-carrying capability. Two conductor sizes are offered in this product range. The 1.5 mm² conductor is formed from seven 0.50 mm copper wires, while the 2.5 mm² conductor is formed from seven 0.67 mm copper wires. Both use plain annealed copper and are integrated into multicore-plus-earth cable constructions for fixed control applications.
Product Highlights
- 6/1kV multicore + earth armoured control cable.
- Plain annealed copper conductors.
- 5 mm² conductor: 7/0.50 mm stranded construction.
- 5 mm² conductor: 7/0.67 mm stranded construction.
- PVC V-90 core insulation.
- Galvanised steel wire armour for mechanical protection.
- PVC 5V-90 orange outer sheath; other colours available on request.
- Core range from 2C+E to 50C+E.
Electrical Performance
Conductor resistance decreases as conductor area increases. In this range, the maximum d.c. resistance at 20°C falls from 13.6 Ω/km for 1.5 mm² to 7.41 Ω/km for 2.5 mm². The corresponding maximum a.c. resistance at 75°C is 16.5 Ω/km and 9.01 Ω/km respectively. Lower conductor resistance supports reduced I²R loss and lower voltage drop over a given circuit length, while the final cable size must also be selected according to installation method, load current and project limits.
Typical Applications
- Commercial building control circuits.
- Industrial plant control and auxiliary circuits.
- Mining electrical systems where mechanical protection is required.
- Utility and electricity-authority control installations.
- Conduit installations.
- Direct-buried control circuits.
- Underground ducts.
- Fixed installations exposed to a risk of mechanical damage.
How to Select
- Choose the required conductor size: 1.5 mm² or 2.5 mm².
- Select the required multicore-plus-earth configuration.
- Check conductor resistance against circuit-length and voltage-drop requirements.
- Confirm the required installation method and current rating.
- Confirm armour and mechanical-protection requirements.
- Confirm sheath colour, marking and project documentation.
- State AS/NZS 1125 together with any other project-specified standards and edition requirements in the RFQ.
