In-House Testing Capability at DGG Power | Reliable MV & HV Equipment Verification

Inside DGG Power’s In-House Testing Capability: How We Ensure Product Reliability Before Delivery

For many overseas customers, product testing is not just a technical step—it is a matter of trust.
Before any medium- or high-voltage equipment is installed into a power system, customers want to know one thing clearly: has this product truly been tested under real, controlled conditions?

At DGG Power, testing is not treated as a formality or a final checkbox. It is an integral part of how we design, manufacture, and deliver reliable power distribution equipment.

An In-House Testing System, Not a Temporary Arrangement

All routine and performance tests at DGG Power are conducted within our own facilities using dedicated test equipment.

We do not rely on temporary setups, rented laboratories, or outsourced testing for daily quality verification.

This in-house testing system allows us to:

• Maintain consistent testing standards

• Control every test condition and parameter

• Record and archive complete test data for traceability

By integrating testing directly into our manufacturing workflow, we ensure that quality verification is continuous—not occasional.

From Assembly Checks to Electrical Performance Verification

Our testing capability spans the entire product validation process, from early-stage inspections to critical electrical performance tests.

These tests are designed to confirm:

• Correct assembly and structural integrity

• Stable mechanical operation and contact performance

• Functional reliability of protective components such as fuses

• Electrical insulation strength and withstand capability under defined conditions

Each test follows established technical requirements and is carried out in a controlled environment to ensure accuracy and repeatability.

Documented Results and Full Traceability

Every test performed is recorded and documented.

This means that test results are not based on verbal confirmation or visual judgment alone, but supported by measurable data and traceable records.

For customers, this provides:

• Clear evidence of compliance with technical requirements

• Confidence in product consistency across different batches

• A transparent quality trail from factory to site

Testing, for us, is not just about passing—it is about proving.

On-Site and Remote Witness Testing for Global Customers

We understand that not every customer can be physically present at the factory.

For customers visiting China, we welcome on-site witness testing, allowing them to observe test procedures directly and communicate with our engineers face to face.

For overseas customers, we support real-time remote witness testing through live video connections.
This enables customers to:

• Observe the testing process as it happens

• Ask questions during the test

• Verify results without geographical limitations

• Distance should never compromise quality verification.

Testing as a Responsibility, Not a Procedure

At DGG Power, testing represents responsibility—responsibility to our customers, to engineers in the field, and to the power systems that depend on our equipment.

By investing in independent testing facilities, transparent procedures, and open verification methods, we aim to deliver more than compliant products.
We deliver confidence, reliability, and long-term trust.

This is how we approach testing.
This is how DGG Power ensures quality—before delivery, not after installation.
