Product Overview

TiraThai, a specialized sub-brand of Jinguan Electric dedicated to transformer and electrical equipment innovations, proudly introduces the ZBW-12 Series Combined Box-Type Substation. This prefabricated, modular unit integrates high-voltage switchgear, transformers (oil-immersed or dry-type), and low-voltage distribution equipment into a compact, factory-assembled enclosure, designed for AC 50Hz systems with rated voltages of 12kV on the high-voltage side and 0.4kV on the low-voltage side. Ideal for urban high-rise buildings, residential areas, industrial parks, mines, oil fields, and construction sites, the ZBW-12 series provides reliable power reception and distribution with a focus on compactness and flexibility.

Jinguan Electric, founded in 1979 as a high-tech enterprise in Nanyang City, Henan Province, China, has evolved from pioneering arrester manufacturing to a global leader in high-voltage transmission and distribution equipment. Embracing Industry 4.0 principles, Jinguan Electric drives core competitiveness through continuous innovation, with TiraThai serving as its premier brand for combined substation solutions. This sub-brand channels Jinguan Electric's expertise into customizable ZBW-12 substations that prioritize safety, efficiency, and environmental adaptability, complying with international standards such as IEC 62271-202, GB/T 17467, and IEEE C37. Certified by UL, cUL, CSA, SGS, CCC, CQC, CTQC, and CE, these units uphold ISO9001 (quality), ISO14001 (environmental), and ISO45001 (health & safety) management systems, backed by a minimum two-year warranty, comprehensive factory acceptance testing (FAT), and dedicated after-sales engineering support for global deployments.

The ZBW-12 series features a robust, corrosion-resistant enclosure with IP54 protection, ensuring durability in harsh environments. Its modular design supports flexible layouts like "目" or "品" shapes, reducing footprint by 30-40% compared to conventional substations. With high overload capacity and low noise, it is tailored for urban and industrial applications. TiraThai's philosophy—"dig 100 meters deep in 1 meter of space"—reflects Jinguan Electric's commitment to precision, delivering substations that minimize installation costs and maximize grid resilience for modern power infrastructure.

Key Features and Engineering Excellence

TiraThai's ZBW-12 Series Combined Box-Type Substation is engineered for superior performance, integrating high-voltage switchgear, transformers, and low-voltage distribution in a compact, prefabricated unit. The corrosion-resistant enclosure, made from stainless steel or treated composite materials, provides IP54 protection against dust, moisture, and harsh weather, ensuring maintenance-free operation in challenging environments. The modular design allows customizable layouts ("目" or "品" shapes) for space-constrained sites, reducing footprint by 30-40%.

The substation supports high overload capacity (up to 120% short-term) and low noise levels (under 55dB), making it ideal for urban residential areas. Integrated monitoring components, such as voltage and current sensors, enable real-time diagnostics, with optional “four remote” functions (telemetry, remote signaling, adjustment, control) for smart grid integration. Jinguan Electric's automated production—featuring robotic assembly, vacuum testing, and AI-driven inspections—guarantees defect-free units with robust construction for seismic and wind resistance.

Compared to traditional substations, TiraThai ZBW-12 units reduce installation time by 40% and costs by 25%, with energy savings of 15-20% through optimized components. Optional features like SCADA integration and surge protection enhance reliability. These attributes not only meet but exceed GB/T 17467 and IEC 62271-202 standards, providing a substation that balances compactness, safety, and scalability.
