Main Tasks

Design, manufacture, supply, and install 330 kV XLPE (cross-linked polyethylene) underground cable, and associated accessories, sub-systems and civil works for:
    a) a single circuit between the tunnel portal at Sydney Park, and Haymarket Substation
    b) twin circuits between Holroyd and Rookwood Road Substations. 

 

Summary

J-Power Systems (JPS) and Diona Pty Ltd formed a joint venture to tender and deliver the project after previously working together to deliver TransGrid’s Cable 42 project almost 10 years ago. The decision to work as a consortium was seen as a way to utilise each party’s expertise and offer TransGrid a proven team that they could have confidence in to deliver this complex project.
The responsibilities within the consortium were allocated as follows:

Diona Route design, design and construction of civil structures, cable laying. Additionally, Diona was the principal contractor for WHS purposes and had overall WHS and environmental responsibility on all site works including cable jointing by JPS.

J-Power Systems Overall design of the cable system, cable and accessories manufacturing, cable jointing, commissioning, operation and maintenance training.

This was Diona’s largest electrical infrastructure project to date and was the first time in Australia that XLPE insulation had been used in cable of this voltage. Over 200 000 man-hours were worked, and there were no lost-time injuries.

The project included:
• production of over 500 drawings
• laying of 160 km of conduit
• hauling of over 100 km of 330 kV cable
• installation of 47 joint bays (10 m long x 2.5 m wide)
• installation of 90 km fibre-optic cable
• building 5 cable bridges
• 420 m of cased boring
• 600 m of horizontal direction drilling
• 147 cable joints
• placement of 50 000 m3 of concrete products.
