- Product Details
70mm armored cable is designed for high-power electrical applications, 70mm 5 core swa conductor made of either copper or aluminum.70mm cable’s conductor is encased in either XLPE or PVC insulation, which ensures thermal stability and effective electrical insulation. A key characteristic of this cable is steel wire armoured or steel tape armoured, which offers substantial protection against physical damage such as crushing or bending. Additionally, the cable is enveloped in a PVC sheath, enhancing its resistance to environmental factors like moisture and UV radiation.

FAQ
What is a 70mm² 4 core armoured cable used for?
It is used for three-phase power distribution with a neutral, commonly installed in industrial plants, commercial buildings, and utility networks where mechanical protection is required.
What is the current carrying capacity (Amps) of 70mm 4-core SWA?
According to BS 7671, it is rated for approximately 207 Amps when buried directly in the ground, and 238 Amps when clipped directly to a surface (free air), based on a 30°C ambient temperature.
What is the voltage drop (mV/A/m) for 70mm cable?
The resistive voltage drop is approximately 0.60 mV/A/m. For long cable runs, this factor is critical to ensure the voltage at the load remains within compliant limits.
