Wuhan HUAYI Electric Power Technology Co., Ltd
Founded in 2005, HUAYI designs and manufactures electrical testing equipment for power systems and high-voltage applications.
Our product range covers high-voltage testing, transformer testing, partial discharge testing, relay protection testing, and cable fault detection. We serve power utilities, equipment manufacturers, testing labs, and industrial companies that need dependable measurement and testing solutions.
From single instruments to complete high-voltage testing systems, we build practical solutions around the test object, required parameters, and site conditions.
What We Manufacture
HUAYI produces electrical testing and condition assessment equipment across these main categories:
AC/DC and VLF hipot testers, high-voltage dividers, and AC resonant test systems for insulation and withstand testing on cables, transformers, and GIS.
Instruments for electrical performance and condition assessment, including DC resistance testers, turns ratio testers, tan delta testers, and sweep frequency response analyzers (SFRA).
PD testers, complete testing systems, and shielded rooms for detecting insulation defects in high-voltage equipment.
Secondary injection relay test sets, circuit breaker analyzers, and contact resistance testers for protection and switchgear maintenance.
Cable fault locators, CT/PT analyzers, insulation and earth resistance testers, transformer oil testers, SF6 gas analyzers, and power analyzers.
Manufacturing & Engineering
Testing requirements vary by equipment, voltage level, capacity, standards, and site conditions. HUAYI combines in-house manufacturing with engineering expertise to configure equipment for specific applications.
Our capabilities include:
- Electrical and mechanical assembly
- Test equipment integration
- High-voltage system configuration
- Functional and performance testing
- Pre-shipment inspection
- Technical documentation and application support
Our facilities include dedicated production areas and an in-house high-voltage laboratory.
Engineering Support
Our engineers support you from equipment selection through to final application.
Before you place an order, our technical team helps evaluate your specific requirements, including:
- Test object and parameters
- Required voltage, current, and capacity
- Measurement standards and site conditions
For customized or system-level projects, we assist with equipment configuration and technical coordination to ensure the solution fits your testing environment.
Testing & Quality Control
In electrical testing, product quality determines measurement reliability and safety. HUAYI enforces strict process control and inspection at every stage before delivery.
- Incoming & Production Control: All components and materials are inspected against production standards. Assembly processes are managed to ensure consistent build quality.
- Functional Testing: Every unit undergoes functional testing to verify performance and key technical parameters before shipment.
- High-Voltage Testing: High-voltage equipment and systems are tested and inspected according to relevant product and application requirements.
- Pre-Shipment Inspection: We verify that the configuration, accessories, and technical specifications match the confirmed order before delivery.
Custom High-Voltage Test Solutions
While standard instruments cover many applications, complex projects often require specific voltages, capacities, or system configurations. HUAYI provides engineering support for these customized requirements.
We configure solutions based on your actual site conditions, including:
- Test object and environment
- Required AC/DC voltage and capacity
- Output current and measurement needs
- System layout and auxiliary equipment
Our engineers work with you to define the exact parameters before recommending a configuration. For high-voltage projects, simply provide your basic test object and requirements, and our team will assist with the solution selection.
