Goldhome's Independently Developed 150kVA/500kV Cascade Insulation Cylinder Test Transformer Shipped to Baoji
On August 20, a set of HM-YDJ-150kVA/500kV cascade insulation cylinder test transformers, independently developed by Wuhan Goldhome Hipot Electric Co., Ltd., was packed and officially loaded onto a truck bound for a power company in Baoji City, Shaanxi Province.
Technological Leadership Meets the Stringent Requirements of UHV Testing
The HM-YDJ-150kVA/500kV cascaded insulation cylinder test transformer shipped this time is a high-end product developed by Goldhome to meet the insulation testing needs of ultra-high voltage (UHV) electrical equipment. The equipment features a two-section cascaded design. It can be used with both sections connected in series to meet the 500kV test voltage requirement, or a single section can be used for testing at voltage levels of 250kV and below, achieving multi-functional use and meeting customers' testing needs across different voltage levels.
The core advantage of this equipment lies in its insulated cylinder structure-featuring an epoxy-cast cylinder shell with full insulation treatment, which significantly enhances insulation strength. Compared to traditional iron-shelled test transformers, it offers the following notable advantages: strong system compatibility and a comprehensive range of voltage capacities; low impedance voltage, with system impedance not exceeding 5%, meeting AC testing requirements; strong moisture resistance, effectively reducing stray magnetic fields, and greatly enhancing the ability to withstand the impact of test short-circuit currents. The equipment achieves an AC measurement accuracy of Class 1.0, fully meeting the stringent requirements for high-voltage power-frequency withstand voltage tests.
Efficient and Orderly Operations Demonstrate Strong Contract Fulfillment Capabilities
Stepping into the Goldhome production workshop, a bustling scene comes into view. Workers are busily and methodically carrying out the final packaging of the HM-YDJ-150kVA/500kV equipment. Due to the equipment's large size and two-stage cascaded structure, the packaging team is taking extra care-first wrapping the critical parts of the equipment with high-density foam, then placing it into a custom-made wooden crate fitted with anti-vibration supports to ensure the equipment remains rock-solid during long-distance transport.
Outside the workshop, a heavy-duty truck fully loaded with the equipment was already in position. Quality inspectors conducted a final check of the equipment list, while logistics specialists confirmed the transport route. With a sharp honk of the horn, the truck slowly pulled out of the factory grounds, officially beginning its journey to Baoji, Shaanxi. From order confirmation to shipment completion, the Goldhome team worked together efficiently to ensure the equipment was delivered to the customer on time.
