As power infrastructure moves closer to residential areas and environmental regulations become increasingly stringent worldwide, low-noise performance is emerging as a key requirement in transformer and reactor applications. Growing urbanization and the expansion of energy infrastructure are increasing the need for effective noise control solutions, particularly for high-voltage equipment located near residential and industrial zones. In this context, acoustic jacketing and enclosure systems are becoming increasingly important for ensuring both regulatory compliance and reduced environmental impact.
Located in Bursa, Türkiye, Pechom collaborates with leading global power transformer manufacturers and has maintained a long-term partnership with GE Vernova for approximately 10 years. The company also works with leading global OEMs such as Hitachi Energy, Hyundai Electric, and BEST. Pechom’s acoustic solutions are specifically designed according to equipment geometry, frequency characteristics, and site requirements. Depending on project requirements, acoustic jacketing solutions integrated onto the equipment can provide up to 10–12 dB of noise reduction, while enclosure solutions designed as independent acoustic structures surrounding the equipment can achieve up to 40 dB noise reduction. Acoustic jacketing systems are implemented by placing acoustic materials between stiffeners and are optimized to occupy minimum space. For already installed equipment in the field, enclosure solutions can also be implemented, supported by project-specific engineering services.
Thanks to a project-based engineering approach, noise reduction performance can be analyzed and predicted during the design stage, before transformer or reactor manufacturing begins. This enables customers to define expected performance levels before production. Target noise levels are determined through verifiable engineering calculations while ensuring that the systems are applied without negatively affecting thermal performance, mechanical integrity, or operational lifetime.
Engineering studies for acoustic performance optimization are supported through analytical calculations and site-specific applications, enabling measurable and sustainable noise control solutions tailored to different project requirements. As low-noise requirements continue to grow across power infrastructure projects, acoustic engineering solutions are expected to play an increasingly important role in transformer and reactor applications.
