Clinton’s Toyota Main Switchboard

This project first began in June 2013 and was issued for construction later that month, despite some major design changes due to the particular nature of the site and at the client’s request all the stakeholders worked efficiently to ensure acceptance of the changes didn’t jeopardise delivery. The design was unique and a little different to our standard main switchboard layout for a project of this type.

It incorporates a sizeable distribution board initially designed to be a separate enclosure, however, due to lack of space in the switchroom it was included in the MSB during the approval process. The distribution section comprised of 3 separate MCB chassis with a combined capacity of 192 poles.

We recommended a more economical range of switchgear for our choice of SPD and moulded case circuit breakers, partly chosen for their functionality but mainly due to significant cost savings passed on to the client.

With our flexible and “can do” approach we are confident our client has received a quality product with years of trouble-free operation.

Symantec DB’s

Symantec is a global leader in providing security, storage and systems management solutions for private consumers and small businesses to the largest global organisations.

In March 2014 Stowe Australia undertook a project for the refurbishment of existing office space at levels 6, 11, 12, 13, 14, 16 and 24 at 207 Kent street Sydney.

After only 24 hours to quote the project Southern Cross Switchboards won the project to design and install 6 of the levels Distribution Boards. The scope was to provide an Energy efficient three tier distribution board. Equipped with Supply Authority Current Transformers Rated at 200A, 6 Power and Lighting split chassis all with private whole current metering. Also included was a 100A Contactor style change over switch for Essential Lighting and Power Chassis, both supplies protected by 2 separate 40KA surge diverters. This design took into consideration of the tight space we had to fit the Distribution Boards whilst still maintaining a sustainable energy solution to Symantec’s offices.

Early May 2014 the manufacturing process of the Distribution Boards was actioned. Early the next month the boards were tested with our Inspection and Test Plan procedure (ITP). After passing the ITP they were then delivered in sections to the Symantec building in Kent St. Later that week Southern Cross Switchboards assisted Stowe Australia to join the sectioned Db’s and position them into the tight spaces that they were designated for. Over two days Southern Cross Switchboards went to site to electrically and mechanically connect the sectioned Db’s and then conduct another ITP to conclude the project.

Darling Harbour Live Temporary MSB

After 25 years of operation, the Sydney Convention and Exhibition Centre Darling harbour closed in January 2014 to make way for the development of the new $1 billion event and exhibition facilities, due for completion in 2016.

A Stowe/Fredon join venture were awarded the $80 million project to undertake the electrical services installation. This included the design, supply, delivery and installation as part of the redevelopment of the site.

In June 2014 Southern Cross Switchboards were awarded the project of supplying and rework of two 1600A Main Switchboards with a quick turnaround of 12 days.

The project consisted of removing the existing MSB’s and have them shipped to our workshop in Silverwater. Once the boards were in the work shop we stripped the boards of all existing switchgear and components. We then re-designed the switchboard whilst maintaining the existing frame. Both boards required a 1600A Service Protection Device along with Supply Authority Current Transformers. The existing MSB2 was too small so we had to manufacture and join a new tier to allow for the supply authority section, which then fed a number of breakers ranging from 800A to 100A MCCBS. There were outdated chassis on the board that we had to source breakers to suit. Both Boards were roughly 3m long and stood 2.3m tall. We managed to utilise some of the existing busbar. However in some sections we had to completely re design the arrangement.

Once the boards were complete we then carried out our Inspection and Test Plan (ITP). We the transported the switchboards to Darling Harbour to Fredon/Stowe. Total duration of this project was 12 days ” Phew “.

Bunnings Batemans Bay

After successfully completing 2 projects with Bunnings at Chatswood and Balgowlah we were excited to commence the project with Bunnings at Batemans Bay.

Batemans Bay situated on the Clyde River Estuary is one of the most beautiful towns in NSW.

The project included 1 x MSB (50kA, IP56, Form 3bih) and 10 x Distribution Boards. While the project requirements were a little similar to previous projects, the specifications were carefully studied by our engineering staff.

The MSB was constructed from marine grade aluminum sheet, folded and welded including a weatherproof return profile and a sloping roof. Internal brass mesh screen was installed to prevent ingress of insects. The external finishing of the board was white.

The 10 off Distribution Boards were also powder coated in white and rated at 160A.

Overall the project was successfully accomplished and met all the requirement of the Customer.
