Goldhome Completes 20800kVA/260kV Mobile Frequency Conversion Resonant Test System for Korean Customer

October 21, 2026 | Goldhome Company News

Wuhan Goldhome Hipot Electrical Co., Ltd. has completed the manufacturing of a 20800kVA/260kV mobile frequency conversion resonant test system for a customer in South Korea. Following the completion of production, the Korean customer visited Goldhome's facility on October 21, 2026, to inspect and accept the equipment.

This project demonstrates Goldhome's capability to manufacture large-capacity, high-voltage test systems and provide customized testing solutions for the power industry.

The 20800kVA/260kV frequency conversion resonant test system is designed for high-voltage AC withstand voltage testing of applicable electrical equipment.

Using frequency conversion and series resonance technology, the system generates the required test voltage. Resonant testing can reduce the power supply capacity required for testing highly capacitive loads, depending on the test object and system configuration.

The vehicle-mounted design integrates the testing equipment into a mobile arrangement, supporting transportation and deployment at different testing locations.

Potential applications include:

High-voltage power cables

Gas-insulated switchgear (GIS)

Power transformers and other compatible capacitive test objects

Substation installation and commissioning tests

The actual application range depends on the system configuration, test voltage, load capacitance, and project requirements.

After manufacturing was completed, the Korean customer visited Goldhome on October 21 to inspect the equipment and carry out the agreed acceptance procedures.

The visit provided an opportunity to review the system configuration, manufacturing quality, and relevant technical documentation. Equipment acceptance is an important stage before delivery, helping confirm that the supplied system meets the agreed technical specifications and project requirements.

Goldhome values direct communication with customers throughout manufacturing and acceptance. The company aims to ensure that equipment configuration and delivery arrangements align with customers' practical testing needs.

High-voltage testing projects often require equipment that combines suitable electrical performance with practical transportation and on-site operation.

A vehicle-mounted resonant test system integrates testing components into a mobile solution, helping simplify transportation and deployment at different sites. The final configuration depends on the vehicle layout, component dimensions, operating requirements, and project conditions.

For utilities, electrical equipment manufacturers, and testing service providers, selecting a suitable resonant test system requires consideration of test voltage, load capacitance, testing frequency, and expected duty cycle.
