BMA Cable

Austdac BMA Cable


Cable type A02; part number G2000 is designed for BMA intercom and pre-start networks. The cable provides power to the BMA’s via the 4mm2 pair and communications and signaling via the 1mm2 pair.

The BMA cable consists of two main elements, an unscreened 4mm2 twisted pair and a screened 1mm2 twisted pair.

The 4mm2 pair is made up of 56 strands of 0.3mm tinned copper wire while the 1mm2 pair is made up of 32 strands of 0.2mm tinned copper wire to provide maximum strength and flexibility. All conductors are insulated with PVC

The 1mm2 pair is screened using a foil tape and a 7/0.25 TC drain conductor.

The outer sheath is constructed from HI-FLEX flame retardant PVC and is coloured blue.

This cable has particularly good L/R ratios despite the large CSA of the conductors.

Every batch of Austdac cable is quality controlled, inspected and tested to ensure that the specified Exi electrical parameters Cc, Lc and Lc/Rc are not exceeded and within tolerance.

This gives our customer’s confidence in the safety of their network installations knowing that any IEC/AS/NZS 60079-25 installation assessment is using reliable and safe cable data.
