Delba Electrical’s large machine division offers expert medium and high voltage rotating machine repairs and rewinding

Rotating machines repairer Delba Electrical stands at the forefront of innovation in the field of electrical rotating machine repairs, boasting a cutting-edge facility specifically designed for the repair and maintenance of medium and high voltage rotating machines, including DC machines, traction motors, wheel motors, alternators and stirrers.

Come and explore the key components of Delba’s repair facility, highlighting its largest Vacuum Pressure Impregnation (VPI) tank, curing oven, burnout oven and heavy-duty cranes, as well as the advanced test bay that ensures the highest quality standards.

Burnout Oven

The burnout oven is a critical component in Delba’s repair arsenal. This specialised, temperature-controlled oven with a quenching system is dedicated to the removal of old insulation materials from rotating machines, preparing them for the meticulous repair and rewinding processes. By employing advanced technologies in the burnout oven, Delba ensures the efficient and thorough elimination of old insulation, setting the stage for the motor’s rejuvenation.

VPI Tank

At the heart of Delba’s repair facility is its largest VPI tank, a technological marvel designed for the impregnation of medium and high voltage rotating machines. With a capacity to accommodate rotating machines of varying sizes, this technology ensures the thorough impregnation of windings with epoxy resin, enhancing insulation and overall performance. The VPI process helps eliminate air pockets and enhances the dielectric strength of the windings. Delba’s commitment to quality is evident in the meticulous process of impregnation that safeguards motors against environmental factors and operational stress.

Curing Oven

Delba Electrical’s repair facility is equipped with a state-of-the-art curing oven, essential for the post-impregnation phase. This oven provides controlled heating conditions to cure the insulation materials, promoting their uniform distribution and enhancing the overall reliability of medium and high voltage rotating machines. The precise temperature and time parameters of the curing process are meticulously maintained to meet stringent industry standards, ensuring motors leave the facility in peak operational condition.

50 t and 100 t Cranes

Handling medium and high voltage rotating machines requires precision and strength, and Delba’s repair facility addresses this with the inclusion of heavy-duty 50 t and 100 t cranes. These cranes facilitate the safe and efficient movement of rotating machines throughout the repair process, from initial disassembly to final reassembly. The robust lifting capacity of these cranes underscores Delba’s commitment to operational safety and efficiency.

Test Bay

Delba Electrical’s commitment to quality assurance is exemplified by its advanced test bay. This facility allows for comprehensive testing of repaired medium and high voltage machines under simulated operating conditions. From insulation resistance tests to load testing, each motor undergoes rigorous assessments to ensure compliance with industry standards and customer specifications. The test bay serves as the final checkpoint, guaranteeing that rotating machines leaving Delba’s facility are not only repaired but optimised for peak performance.

The company’s repair facility for medium and high voltage rotating machines stands as a testament to its dedication to excellence. Through the integration of cutting-edge technology, from the largest VPI tank to precision curing and burnout ovens, as well as heavy-duty cranes and a sophisticated test bay, Delba ensures that each repaired motor meets and exceeds the expectations of its clients. In an industry where reliability is paramount, Delba’s commitment to quality repair processes positions it as a leader in the electrical motor repair domain.
