COLLINSVILLE POWER STATION
REFURBISHMENT PROJECT
Collinsville, Queensland, Australia
Scope: A casestudy on the use of KRONE’s Industrial Wiring Products within the
control wiring system of Collinsville Power Station.
Date: September, 1997
Prepared by: Charles Grasso, Account Manager
Power & Control Division, KRONE (Australia) Technique Pty Limited
Project Background
Collinsville, a thermal energy
driven power station with a
generating capacity of 200MW,
is located on Australia’s
Queensland coast.
First commissioned in the
late 1960’s, the power station
was later decommissioned in
1988.
The current refurbishment
project began in mid 1997 and
is a joint venture between
Northern River Generation and
Transfield Power Technologies.
Initial Evaluation
Using conventional screw
technology, it takes 4 1/2 hours,
on average, to prepare a field
termination box with 180
connections. The labour time
includes glanding, marking,
looming, stripping, ferruling and
screwing of wires.
Transfield Power
Technologies found that the
labour time could be reduced to
1 hour if KRONE’s Insulation
Displacement Connection (IDC)
technology is used. This
method does not require any
wire preparation prior to
termination.
The decision to use
KRONE’s Terminator
™
and Profil
modules was also influenced by
user benefits such as:
• the reliability of the KRONE
IDC contact
• the robust construction of the
module
• quick clip-on mounting of
modules to DIN rail (time
savings of up to 94%)
• neat and tidy installation with
work access from top of
module
• disconnection feature for
circuit isolation
• high density system
• integral numbering system
Scope of Work
The scope of work covers the
instrumentation and control of
five turbines (one 60MW and
four 35MW) and five boilers
with wiring extending from the
control rooms out into the field.
It is estimated that the
Collinsville refurbishment project
will involve in excess of 130,000
single terminations of which
75% will require a disconnection
facility.
KRONE’s Terminator
™
and
Profil terminal modules are being
used on the power station’s
control wiring system.
The wiring from the
Programmable Computer
Management System (PCMS)
cabinets requires both
disconnection and feed-through
terminations to allow for
patching of field devices.

Scope of work for DMC Electrical Services.
The labour time required for wiring
180 connections was reduced by
78% when using KRONE’s IDC
technology.
The existing density of the
exchange racks is required to be
doubled, making space a real
premium.
With the Terminator
™
System, all work is carried out
from the top of the modules
and there is no need for lugs to
be fitted. Therefore, KRONE’s
termination technology enables
the density of terminations to be
doubled without sacrificing the
required working space.

Disconnect Modules
The wiring in the
exchange racks involves looming
the wires to their termination
points without the use of slotted
ducts.
Normally, excess wire is
cropped, measured and cut to
length before the wire can be
terminated.
By using KRONE’s
“Wire
Cutting and Termination Tool”
,
the cropping and measuring of
each wire can be eliminated.
This timesaving tool cuts the
wire to length and completes
the termination in one single
operation.
Labelling
The labeling of terminals is kept
simple by utilising the built-in
prefix system on the KRONE
modules. In addition, the
KRONE label holder, fitted with a
label carrier and ID characters, is
used.
Cables
Dekoron cable (0.5 and 1.5mm
2
)
is used for carrying both analog
and digital signals (up to 110V
DC). The larger dia cable is used
where mechanical stress is a
concern and for patching
between circuits.

The KRONE Advantage
By using KRONE Terminator
™
and Profil Modules, it is
estimated that, during the
installation, in excess of
$60,000 and 2,500 hours will
be saved.
