Founded in 2009, Zhejiang Zhidian Amorphous Electrical Co., Ltd. (Quzhou Zhidian Amorphous Electrical) is a national high-tech enterprise, Zhejiang provincial specialized, refined and innovative SME, and provincial science and technology-based SME. The enterprise holds 47 transformer-related patents, 2 software copyrights and 99 industrial qualification certificates. It has long participated in domestic power engineering bidding projects with mature production and project supporting capabilities.
The company's core products are amorphous alloy oil-immersed distribution transformers, which feature lower no-load loss and better energy-saving performance than conventional silicon steel transformers. Its product portfolio also covers dry-type transformers, box-type substations, corrugated oil tanks, and complete high and low voltage electrical equipment. The enterprise independently masters the full production technology of amorphous transformers, adopts self-developed parametric design software, and is equipped with dedicated core stacking tooling and professional coil winding equipment. Its products are widely used in power grid upgrading, residential power distribution, factory power supply, photovoltaic supporting projects, rural grid energy-saving renovation and other scenarios.
The enterprise's flagship 10kV amorphous alloy distribution transformer features low no-load loss, low operating noise and stable temperature rise, and is suitable for long-term continuous operation. Complying with national energy-saving power distribution policies, it is widely applied to urban and rural power grids as well as industrial and commercial power distribution projects.
Nanke Electric supplied the enterprise with a 35kV automatic distribution transformer test system to meet the factory test requirements of distribution transformers. Our full turnkey services cover equipment customization, site layout planning, on-site installation & commissioning, as well as professional operation training for on-site personnel.

(1) Automatic integrated testing simplifies test procedures: Adopting an automatic control architecture, the 35kV automatic distribution transformer test system supports automatic switching of test items with one-time wiring. It eliminates repeated wiring and manual commissioning required by traditional testing equipment, reduces manual intervention, and fits batch factory quality inspection work.
(2) Comprehensive test items comply with industrial standards: The system supports multi-dimensional tests covering no-load characteristics, load characteristics, insulation withstand voltage and temperature rise. It is applicable to factory testing of 10kV and 35kV oil-immersed, dry-type and amorphous alloy transformers, fully complying with current national and industrial test specifications.
(3) Automatic data acquisition and conversion reduce manual errors: The system collects real-time test data and automatically completes standard temperature conversion for load loss and short-circuit impedance. It effectively avoids manual reading and calculation errors, providing accurate and standardized data for quality inspection archives and official test reports.
(4) Wide parameter coverage adapts to multiple product specifications: Designed for a maximum test voltage of 35kV, the system covers a complete range of voltage, capacity and impedance parameters. It satisfies batch quality inspection of the enterprise's existing 10kV amorphous transformers and supports R&D tests for new 35kV transformer products.
(5) One-stop service supports independent quality inspection system construction: Nanke Electric provides full lifecycle services including equipment supply, site layout planning, on-site installation and commissioning, operational training and after-sales maintenance. The complete solution helps customers build in-house test laboratories and optimize internal quality management systems.
