FOREWORD
General
This Standard was prepared by Communications Alliance and most recently
revised by the WC65 Defence Cabling Standard Revision Working Committee. It is
one of a series of Telecommunication Standards developed under the
Memorandum of Understanding between the Australian Communications
Authority (ACA) and the Australian Communications Industry Forum.
Note:
On 1 July 2005 the ACA became the Australian Communications and Media
Authority (ACMA) and the Memorandum of Understanding continues in effect as if
the reference to the ACA were a reference to ACMA.
Communications Alliance was formed in 2006 and continues the functions
previously fulfilled by ACIF.
This Standard is a revision of AS/ACIF S035:2008 Requirements for installation of
temporary field telecommunications customer cabling for defence purposes
Standard.
This Standard is the result of a consensus among representatives on the
Communications Alliance Working Committee to produce it as an Australian
Standard.
Intellectual property rights
Equipment which is manufactured to comply with this Standard may require the
use of technology which is protected by patent rights in Australia. Questions
about the availability of such technology, under licence or otherwise, should be
directed to the patent holder or Australian licensee (if known) or through enquiry
at IP Australia which incorporates the Patent, Designs and Trade Marks Offices.

Regulatory notice
Attention is drawn to the fact that the installation and repair of customer cabling
is subject to the Telecommunications Cabling Provider Rules, which require
customer cabling work to be performed or supervised by a person with the
appropriate cabling provider registration and to be installed in accordance with
AS/CA S009 (Wiring Rules). This requirement is determined by legislation and
AS/CA S035:2015 COPYRIGHT

- ii -
subordinate regulatory instruments administered by the Australian
Communications and Media Authority (ACMA).
The Telecommunications (Types of Cabling Work) Declaration 2013, which calls up
this Standard, exempts Department of Defence (DoD) personnel and overseas
defence forces from the requirements to have a cabling provider registration or
to comply with AS/CA S009, provided the requirements of this technical standard
have been met. This Standard applies only to installation of temporary field
telecommunications customer cabling for DoD purposes during exercise, training
or operational deployment in any environment.

insulating material or metal earthed in accordance with Clause 5.13
unless all of the following are met:
(a)
The temporary cable and the LV power cable are terminated
on equipment whose access is restricted to suitably qualified
and authorised defence personnel.
(b)
Separate cables are used for LV power and
telecommunications.
(c)
Any telecommunications circuit that is terminated on the
restricted access equipment—
(i)
does not share the same cable sheath as any other
telecommunications service; and
(ii)
only connects to a Telecommunications Network via an
LIU as specified in Clause 5.2.
5.11.3
Separation from HV circuit terminations
5.11.3.1
Shared enclosure
The electrical conductors and terminations of a temporary cable
shall not be located within the same enclosure or building cavity as
the conductors and terminations of an HV circuit.
Note 1: Temporary cable conductors and terminations and HV conductors
and terminations may be contained in the same room, subject to
the requirements of Clause 5.11.3.2, as long as the HV conductors
and terminations are separately enclosed within the room.
Note 2: Installation of a distributor in the same room as any HV equipment is
not recommended.
5.11.3.2
Separation of enclosures
The enclosed electrical conductors and terminations of a temporary
cable shall be separated from the conductors and terminations of a
separately enclosed HV circuit by a minimum distance of 450 mm,
whether or not there is an interposing barrier.
Note:
The 450 mm distance is measured between the actual conductors
and terminations within their respective enclosures, not between the
enclosures. However, allowance should be made for any future
equipment expansion within each enclosure.
5.12
Separation from power cables
5.12.1
LV power cables
A temporary cable that contains electrically conductive elements
shall be separated from any LV power cable so as to prevent cable
insulation damage that may result in mutual electrical contact
between the cable conductors (e.g. due to pressure, impact,
abrasion or heat).

Note:
Cable crossings are a particular concern. The cables should be
separated at crossings by suitable spacing or a durable insulating
barrier.
5.12.2
HV power circuits
5.12.2.1
Single-core cables
A temporary cable that contains electrically conductive elements
and which runs alongside or crosses a single-core cable carrying an
HV circuit shall be separated for its entire length from the single-core
cable by a distance of at least 450 mm whether or not there is an
interposing barrier.
5.12.2.2
Multi-core cables
A temporary cable that contains electrically conductive elements
and which runs alongside or crosses a multi-core cable carrying an
HV circuit shall be separated for its entire length from the multi-core
cable by—
(a)
a distance of not less than 300 mm; or
(b)
a distance of not less than 150 mm where there is an
interposing barrier that—
Note:
(i)
is of such dimensions that at every point the shortest
path between the temporary cable and the multi-core
HV cable around the barrier is at least 175 mm measured
from the outside of the cable sheaths; and
(ii)
is made of either durable insulating material or metal
earthed in accordance with Clause 5.13.
Compliance with Item (b) may be achieved by the enclosure of
either the temporary cable or the HV cable in conduit.
5.12.3
Aerial cabling
5.12.3.1
Attachment to power poles
Aerial temporary cabling shall not attach to any of the following:
(a)
Any pole or structure carrying an aerial power line exceeding
66 kV.
(b)
Any conductive pole or structure carrying an HV power line of
any voltage.
(c)
Any non-conductive pole or structure carrying an HV power
line unless the HV power line does not exceed 66 kV and there
is an existing LV power line below the HV power line.
(d)
Any power pole that carries an HV power transformer.
Note:
Conductive poles include poles manufactured from steel, concrete
or timber.

5.12.3.2
Crossings
(a)
Aerial temporary cabling shall not cross an aerial power line
exceeding 330 kV.
Note:
(b)
5.12.3.3
Where it is necessary for temporary cabling to cross an aerial
power line exceeding 330 kV, the temporary cabling should
be installed underground for at least 50 m each side of the
power line at an angle as near as practicable to 90° to the
power line route.
Where aerial temporary cabling crosses any aerial power line it
shall cross below the aerial power line.
Separation from aerial power lines
Aerial temporary cabling shall be separated from aerial power lines
by the minimum distances indicated in Table 1.
5.13
Earthing
5.13.1
Resistance
Any earthing connection made for safety purposes should have a
maximum resistance to ground of 30 Ω (5 Ω preferred).
5.13.2
Access to earthing bars or terminals
Any earthing bar or terminal, other than a connection to an earth
electrode, shall be enclosed or located to prevent unintentional
contact by a person who is not installing or accessing the cabling.

Notes:
1. LV power and telecommunications conduits may share the same catenary support as long as they
are independently secured to the catenary support and separated by the enclosure of either the
power cable or the telecommunications cable in conduit or are otherwise protected from damage
that may result in mutual electrical contact between the cable conductors.
2
‘Independently supported, insulated LV’ means—
(a) aerial bundled cable (ABC);
(b) insulated cable on a separate catenary support;
(c) aerial insulated cable to a light fitting; or
(d) an insulated service lead or neutral-screened cable servicing a building.
3
Earthed Metallic Screened HV ABC may be treated as ‘Independently supported insulated LV’.
4. HV separations at the pole apply where no aerial LV power line is installed below the HV (attachment
to the pole in such cases is only permitted for crossings).
5. Where the horizontal distance cannot be met, the radial distance applies. The horizontal distance is
measured from the vertical projection below the aerial power line to any part of the
telecommunications pole or structure. The radial distance is measured from the power line itself to the
closest part of the telecommunications pole or structure.
6. Attachment of temporary cabling to a pole or structure carrying power lines exceeding 66 kV is not
permitted.
7. Aerial temporary cabling crossings with aerial power lines exceeding 330 kV are not permitted. Where
it is necessary for temporary cabling to cross power lines exceeding 330 kV, the temporary cabling
should be installed underground for at least 50 m each side of the power lines at an angle as close as
practicable to 90° to the power line route.
8. The temporary cable bearer is to be insulated from any conductive pole or structure and insulated or
shrouded to prevent accidental personal contact with the bearer by an electrical worker accessing
the power line.
