North West Queensland, Australia

Scope: A case study on the use of the KRONE TERMINATOR™ system

for wiring control equipment for the Pasminco Century Mine and port loading facility.

Prepared by: Jeff Glen, Manager Power & Control Division

KRONE (Australia) Technique Pty Limited

With responsibility for installing controls for the mine site processes, Stork Electricalcompleted approximately 93,000 terminations using the KRONE system According to Paul Hopkins, Project Manager, the system is much easier to use compared to screw terminals and more than twice as fast, resulting in substantial time and labour savings for the project

Mannesmann Rexrothsupplied hydraulic power packs for actuation of the Severe Service Ball Valves Sam Soury, Manager, Electronics and Controls, agreed that the main benefit of the IDC technology was termination speed as it eliminates the need for stripping and screwing

Coogee Chemical, operating the mine's chemical reagent plant, believes reliability is the main advantage of the IDC technique over screw type terminals According to Erik Nielsen, Electrical Superviser, the company has never had a loose connection since it began using the KRONE TERMINATOR™ system in 1996

The Pasminco Century Mine is in one of the most

remote areas of Queensland, approximately 250 km

northwest of Mt Isa

Century will be one of the world's largest zinc mines,

yielding approximately 880,000 tonnes of zinc

concentrate and 70,000 tonnes of lead concentrate,

or around 8% of global production

Project managed by the Century Minenco Bechtel

(CMB) Joint Venture, the AU$850 million

development include an underground pipeline and

the development of port loading facilities at Karumba

In September 1998 site electrical works began for the

Century project, requiring a high degree of control

cabling for low voltage applications

The criteria for selecting a connecting

sys-tem were reliability in harsh conditions, low

installation cost, reduced installation time

and less risk of faulty installation.

With the capacity to produce corrosion and vibration

resistant Insulation Displacement Connections (IDC),

KRONE's TERMINATOR™ solution was written into the

electrical design specifications for the mine site's

control equipment by Tim Smith, Lead Electrical

Engineer for the CMB Joint Venture Uniformity of

terminals is important for large operations like the

Century project as there is often a need to not only

maintain but add to installations once they are in place

The TERMINATOR™ system is ideal for mine

environments as it is designed for applications that require

a large number of connections and for machinery where

screw connections might loosen It also reduces routine

maintenance and delays in commissioning

Time Savings:

In the factory

1 Per termination 45 seconds

2 Per 100,000 terminations 1250 hours

3 @ $35.00 per hour $A43,750

On site

1 Per termination 45 seconds

2 Per 100,000 terminations 1250 hours

3 @ $50.00 per hour $A62,500

The total approximate time saving on this project were 2,500 hours and $106,250.

Universal Motor Kontrol (UMK)supplied 15 Motor

Control Centres, consisting of more than 200 tiers of its

new Kontrol 5000 to the Century Mine site, believed to

be the largest 690V installation in Australia The MCC’s

featured 4000A ACB incomers and busties, over 450

drives and PLC cubicles which required in excess of 5000

terminations using TERMINATOR™

UMK's Production Manager estimated that the use of

KRONE's TERMINATOR™ solution resulted in time savings

of around 45 seconds per terminal With a short lead

time on the project, the high speed terminal system was

crucial in enabling UMK to deliver on schedule

Barclay Mowlem Constructioninstalled wiring at the port loading facility in Karumba for PLCs, the digital control system, field units and instruments Mark Richardson, Electrical Superviser, said that the TERMINATOR™ solution, including KRONE's wire cutting and termination tool, was highly effective due to the time savings achieved and ease

of use by the electrical installation team

J&P Richardsonprovided water filtration equipment to the Century port site at Karumba With around 2,000 terminals to install, Clayton Berlin, Electrical Design Engineer, found the KRONE modules easier to use and more reliable than other connection systems

Foxboro Australia, designed and constructed the project's

complete field control and automation system With

responsibility for running the mine's equipment, Foxboro

was a large user of KRONE TERMINATORT Mmodules for the

main PLC panels

Switchboard manufacturer R G Laddbuilt 30 marshalling

cabinets containing 2000 blocks for Foxboro, with each

block holding 10 terminals Brenton Stokes, Project

Manager, commented that TERMINATOR™ was easy to

install and that the terminations were carried out on site

without problem

Central Coast Switchboardswas sub-contracted by Weir

Engineeringto supply the control panels for the dewatering

process, and utilised the TERMINATOR™ range of products
