THERMAL RESISTIVITY PRODUCT (TR)

THERMAL RESISTIVITY PRODUCT (TR)

Our Thermal Resistivity (TR) product has been extensively tested by a leading NATA laboratory, which is a specialist in industrial construction products. Its performance has been tested to the highest specifications and has proven to be excellent with extremely low thermal resistivity ratings at several different compaction rates. Multi Minerals Australia’s price for TR is very competitive.

Available in -5mm size

TR Definition: This product is crucial in managing temperature and enhancing the performance of underground power cable systems. Its applications are focused on ensuring the safe and efficient heat transmission away from these cables. Its benefits include: Heat dissipation, Temperature management, High thermal conductivity, Cable protection, Uniform cooling, and Higher energy load capability. This makes it one of the most reliable forms of thermal resistivity backfill available in the market.

Multi Minerals Australia’s TR product has been supplied to several high-profile solar and wind farms. These clients are extremely happy with the product. It flows easily, is easy to work with, and binds very well in situ. Additionally, supply in continuous and large volumes is met with ease, whether the demand is for thermal resistivity sand or bulk backfill material.

Trucks Being Loaded with Thermal Resistivity Product

Tens of thousands of tonnes of TR have been supplied to the following clients:

The Crudine Ridge Wind Farm, NSW

The Crudine Ridge Wind Farm is located in Wiradjuri Country, 45km south of Mudgee. The wind project became fully operational in 2022, producing enough electricity to power more than 75,000 homes and preventing 266,000 tonnes of carbon emissions annually. The wind farm is supplying clean energy to Nestlé Australia, Sydney Airport, and others using low thermal resistivity material to support long-term infrastructure.

Wellington Solar Farm (Wuuluman)

This project consists of a 200MWdc solar farm at Goolma Road, Wuuluman, near Wellington in NSW.

The solar farm is situated on 316 hectares of grazed agricultural land, which has predominantly been used for sheep and cattle grazing (picture above).

It has:

  • Significant contribution to clean energy production
  • Minimal disruption to existing agricultural practices
  • Visual mitigation measures, like vegetation screening, are used to address aesthetic concerns
  • Potential for co-existence with grazing activities

The Beryl Solar Farm, NSW

The Beryl Solar Farm is a 109 MW DC project located approximately five kilometres west of Gulgong, NSW.

The Beryl Solar Farm has a 15-year Power Purchase Agreement with Sydney Metro and is used to meet the operational electricity needs of the Sydney Metro Northwest rail link.

The Beryl Solar Farm will generate electricity with the smallest carbon footprint of any PV technology available and is expected to generate more than 199,000 MWh of electricity per operating year. It will produce energy to run approximately 25,000 average NSW homes, displacing more than 167,000 metric tonnes of carbon dioxide emissions per year.
