Ampcontrol designs and manufactures Belt Substations which can include up to 10 power distribution outlets and are offered in both flameproof and ingress protected (IP56) enclosures.
Ampcontrol designs and manufactures a range of substations up to 7.5MVA and customises each to meet the applications required. Belt Substations are typically 11kV/1000V, up to 2.5MVA and are typically Ingress Protected (IP56) variations.
The Belt Substations can be designed to support both Fluid Coupling Starters such as CST and Voith systems or using VVVF Drive technology. With each different type of starter comes a set of different requirements for cooling of motors and gearboxes, conveyor braking requirements and winch tensioning needs. In addition to these power needs the substations are designed to supply the control and communications needs for the belt and its field inputs.
11kV connections are typically provided via a flameproof coupler. All 11kV equipment is housed in the High Tension (HT) Enclosure of the substation. The HT Enclosure may incorporate switched or nonswitched through supplies and 11kV DOL Conveyor Motor Starters. Integrated into the HT enclosure are the isolation, earthing and protection required for the main transformer. Protection will include meeting all requirements for electrical protection of a substation as detailed in AS4871.2012.
Transformer options available include nitrogen filled, dry type transformers (GNAN cooling system), mineral oil filled (ONAN) transformers and high flash point vegetable or silicon based oils. All GNAN transformers are built to meet IEC standards for explosion protection technique Ex p. The oil filled transformer options provide are built to Australian standards for the class of transformer specified.
