SINAMICS G180 are compact devices, cabinet systems and cabinet units (air and liquid cooled) for variable-speed drives in plant and machinery construction; which have been specifically designed for applications in oil and gas, the chemical and process industries. They have been specially developed to address the requirements of drives with square law and constant load characteristics. SINAMICS G180 represents the optimum drive solution that can be adapted to the various sector-specific requirements in the core sectors using a wide range of options and X options (special, customer-specific options). SINAMICS G180 can be flexibly integrated into any automation concept, either using conventional control or via a bus system. All of the drive requirements – from the motor through the converter transformer, cabling, converter, line conditions and link to the supervisory control level – are taken into consideration from the very start.
