Heavy duty rubber flexible cables
Heavy duty construction site leads for drills, pumps,
Cranes, hoists & festoon systems
Stage & theatre power & lighting
Portable motors, generators & power supplies
Rubber cables designed as a heavy duty flexible for
dry, damp and wet environments, areas of stress
caused by vibration or impact and is resistant to abrasion,
exposure to radiated heat and chemical contamination.
Rubber cables consist of finely stranded copper
conductors laid up to provide a flexible design. R-EP-90
elastomer insulation provides improved current capacities.
The construction is in accordance with the Australian
Standards AS 1125, AS 3191, AS 3116 and DIN/VDE
0282 IEC332-1 and CENELEC standards for O7RN.
Minimum permissible ambient temperature -40°C
Maximum permissible short circuit temperature
Minimum ambient temperature for optimum fully
flexible operation -25°C
MINIMUM BENDING RADII
The following minimum bending radii should be observed
to ensure operating reliability.
For fixed installation 4 x cable diameter
When freely flexing 5 x cable diameter
CURRENT CARRYING CAPACITY
Current ratings are based on continuous operation
at an ambient temperature of 40°C. At other
temperatures these values must be converted using the
Uo/U = 0.6/1kV
Maximum operating voltages in:
3 phase AC operation
Uo/U = 0.7/1.15kV
Uo/U = 0.9/1.73kV
AC test voltage
*The cable is designated 450/750V with EI1 insulation compound
accordance with VDE/IEC and meets or exceeds the
Australian Standard AS 3116 for the voltage rating of
CORE COLOUR IDENTIFICATION

black insulation sequentially numbered
including a green/yellow earth core.
The maximum allowable tensile stress is 15N/mm2.
This ensures no conductor damage will occur in operation.
