Tyree Transformers recently completed the supply of transformer substations for the upgrade of the Bass Point Quarry which is located immediately south of Shellharbour on the south coast of New South Wales.
The Bass Point Quarry operation is owned by Hanson Cement producing aggregate and it has been in operation since 1880 and has approval to operate out to 2044. The electrical upgrade project required Tyree to provide seven new 11kV/433V transformer substations ranging in capacity from 315kVA to 2000kVA.
Being a quarry site the substations where required to fully comply to the New South Wales Work Health and Safety (Mine and Petroleum Sites) Act 2013.
Tyree designed the transformer substations to ensure compliance to this Act and the resulting design incorporated Sensitive Earth Leakage protection compliant to AS2081, enclosures compliant to Internal Arc Containment to AS62271.202 for operator safety and AS2067 and transformers compliant to AS60076. The substations also incorporated medium voltage switchgear with remote operation panels and type tested Form3b Low Voltage Switchboards to ensure operator safety during switching operations.
The Bass Point site is surrounded by ocean on three sides and a number of the substations were located within 100 meters of the ocean, therefore all for the substations were assembled using transformer tanks & base frames which were fully hot dipped galvanised and housed in powder painted 304 grade stainless steel enclosures with an integral oil containment bund also fabricated from stainless steel.
