DAX 10 THE HIGHEST POWERED DAXFOR A GENERATION—— Offering solutions up to 200 MW—— Suitable for a variety of locations in a variety of environments—— Viable alternative to hydrogen-cooled generators

DAX 10 AIR-COOlED GENERATOR

BRUSH has built on its extensive knowledge of supplying generators to both the gas and steam turbine market to offer a new and exciting range of air-cooled generators.

Building on over 130 years’ experience, the best design practices and manufacturing techniques have been utilized to extend the current range of air-cooled generators to 200 MW, for both 50 and 60 Hz applications.

The first of this new generation of DAX 10 generators has just completed its second year of successful operation.

The DAX 10 range of air-cooled generators offers a real alternative to the hydrogen-cooled generator, offering simpler maintenance and operation as well as lower auxiliary costs, whilst maintaining project-specific output and efficiency requirements.

The DAX 10 range of air-cooled generators is versatile for a number of different applications and a variety of different environments, available to operate in a range of local environmental conditions.

The DAX 10 range of air-cooled generators is fully compliant with the requirements of the relevant international standard specifications, including IEC and IEEE.

Based on real-build experience, the new DAX 10 range of generators will continue and contribute to BRUSH’s ability to meet demanding interface requirements of the turbine manufacturer, coupled with competitive prices and deliveries.

Principles of stator design

—— Sprung core to minimize vibrations onto foundations

—— Pressed endwindings for optimal heat dissipation

—— Radially ventilated corepack construction

—— Upgraded resin rich insulation utilizing new flat glass technology

Principles of rotor design

—— Directly-cooled, ensuring uniform flow and temperature along the length of the rotor

Cooling methodology

—— Cooled by air, either open air-cooled circuit or closed water: air circuit configuration

—— Cooling air is forced around the generator by means of two axial fans

—— Integral, multi-chamber cooling system to ensure uniform temperature profile throughout the length of the generator

Excitation system

—— Brushless or static options available

—— Excitation systems based on proven systems

Bearing arrangement

—— Endframe or pedestal arrangement available, depending on the active core length required for the application

Versatile to surroundings

—— Housing suitable for outdoor installation

—— Applicable for 50 & 60 Hz applications, both gas and steam turbine arrangements
