On January 11, 2025, a complete set of SF6-insulated, metal-enclosed power-frequency test transformers independently developed by Goldhome was shipped to Pingdingshan.
On January 11, 2025, the Goldhome factory was bustling with activity. A complete set of HMGTU-300kVA/500kV SF6-insulated metal-enclosed power frequency test transformers-entirely independently researched, designed, and manufactured by the company-successfully passed all factory tests and internal acceptance inspections, entering the final packaging stage. Workers collaborated efficiently, carrying out anti-vibration reinforcement, sealing, and hoisting operations, creating a scene that was both intense and orderly. A heavy-duty truck fully loaded with the equipment stood ready to depart, about to leave the factory grounds and head to the customer's site in Pingdingshan, Henan.
The technical supervisor closely monitored the packing process throughout, meticulously verifying the shipping list and protective measures to ensure that this core testing equipment-with its high voltage rating and stringent insulation requirements-would remain completely safe during the long-distance transport.
- Product Features: Advanced SF6 insulation technology, specifically designed for demanding testing environments
- The HMGTU-300kVA/500kV SF6-insulated, metal-enclosed power frequency test transformer system shipped this time is a flagship product of Goldhome in the high-voltage testing equipment sector, offering the following core advantages:
- High Voltage Rating: With a rated capacity of 300kVA and a maximum test voltage of 500kV, it meets the high-voltage testing requirements for power equipment, including power frequency withstand voltage and partial discharge testing.
- SF6 Metal-Enclosed Structure: Utilizing SF6 gas as the primary insulating medium and featuring a fully metal-enclosed design, it offers excellent insulation performance and strong resistance to contamination, making it suitable for laboratory and field use under various environmental conditions.
- Integrated System Design: Combines the test transformer, voltage regulation and control, and measurement and protection functions into a single unit, offering convenient operation and high data accuracy, significantly enhancing testing efficiency and safety.
- High Reliability: Key components are manufactured in-house and undergo rigorous type testing and factory inspections to ensure long-term stable operation.
- Efficient Order Fulfillment: From order placement to shipment, this project once again demonstrates Goldhome's production capacity and execution capabilities.
Given the technical complexity and high degree of customization of this unit-from confirming customer requirements, designing solutions, scheduling material production, and assembly and debugging to final factory acceptance-Goldhome leveraged its mature flexible production system and comprehensive supply chain resources to complete the entire manufacturing process in less than 40 days, ensuring on-time delivery.
"This 500kV-class SF6-insulated test transformer imposes extremely stringent requirements on gas chamber sealing, partial discharge control, and electric field structure design," stated Goldhome's production manager. "Our technical team and production crews worked in close coordination to pass all factory tests on the first attempt, once again demonstrating Goldhome's mass delivery capabilities and technical expertise in the field of high-voltage specialty testing equipment."
