Goldhome HMGTU-200kVA/500kV Partial Discharge AC Withstand Voltage Test Set: Meeting the Core Needs of Overseas Procurement
Against the backdrop of global high-voltage power infrastructure development and grid operation and maintenance upgrades, the demand for insulation testing and partial discharge testing of large-scale 500kV-class power equipment continues to rise. Launched by Wuhan Goldhome Hipot Electrical Co., Ltd., the HMGTU-200KVA/500kV PD-Type AC Withstand Voltage Test Set has become a core high-voltage testing device of great interest to domestic and international buyers and power companies alike, thanks to its superior performance and comprehensive cross-border support services. It precisely addresses practical concerns that customers care about most, such as transportation, warranty, and on-site operation.
This equipment is a gas-insulated, partial-discharge-free testing system independently developed by Goldhome. It is specifically designed for factory testing, handover acceptance, and on-site withstand voltage and partial discharge testing of equipment such as GIS (Gas-Insulated Switchgear), ultra-high-voltage cables, large transformers, and current transformers. Unlike conventional withstand voltage equipment, it features a fully sealed SF6 gas-filled structure. Under rated voltage, the overall partial discharge level is stably controlled between 1–3 pC. With strong interference resistance, it adapts to complex testing environments in various overseas regions. It offers smooth voltage ramp-up, sensitive protection, and accurate, reliable test data, fully complying with international high-voltage testing standards.
For overseas buyers, the key concerns-cross-border transport feasibility, delivery times, and warranty/after-sales service-are all addressed by Goldhome with standardized implementation solutions, which constitute the core competitive advantage of this product over similar competitors. The equipment features a modular, disassemblable design with lightweight main components, making it suitable for all modes of transport-sea, air, and land-and enabling safe delivery to any country worldwide without shipping restrictions. Standard sea freight to Southeast Asia, Central Asia, and South America typically takes 25–45 days. The entire shipment is protected by specialized shock- and moisture-resistant packaging and equipped with real-time tracking, significantly reducing the risk of damage during long-distance transit and ensuring the equipment arrives at its destination in perfect condition.
Regarding warranty coverage, the equipment comes with a 2-year free warranty for the entire unit and a 3-year warranty for core high-voltage components-far exceeding the industry standard of a 1-year warranty-with coverage extending to all overseas projects worldwide. During the warranty period, free replacement of parts and remote technical troubleshooting are provided for non-human-induced quality issues. After the warranty period expires, we provide lifetime technical support with an 8-hour rapid response for overseas inquiries. Engineers can provide on-site installation and operational training services overseas as needed, eliminating any concerns overseas customers may have regarding equipment use and maintenance.
