2026-03-02

For decades, An Yida Enterprise has remained steadfastly committed to the research and development and manufacturing of core equipment in the power transmission and distribution sector. Its product portfolio encompasses complete systems such as transformers, packaged substations, high- and low-voltage switchgear, and cable distribution boxes, all dedicated to providing global customers with efficient and reliable power solutions. The product series are designed based on functionality and application scenarios, emphasizing energy efficiency, safety, and integration. The main product categories include:

I. Transformer Series

Oil-immersed transformers: Suitable for long-distance power transmission and industrial applications, they feature high stability and durability and employ a fully sealed design to minimize maintenance requirements.

Dry-type transformers: Focused on energy efficiency and environmental protection, suitable for urban power grids and sensitive environments; optimized core design reduces losses.

Specialty transformers—including rectifier transformers and traction transformers—meet the customized needs of industrial sectors such as metallurgy and rail transit.

II. Box-type Substation Series

European-style packaged substation: Integrates high-voltage switchgear, low-voltage switchgear, and transformer into a compact structure, making it ideal for urban distribution network upgrades and enabling rapid deployment.

American-style packaged substations: Simplified design, emphasis on maintenance-free features, suitability for harsh outdoor environments, and reduced life-cycle costs.

Chinese-style packaged substations: Improved based on the American-style design, with enhanced switch protection performance, suitable for commercial and industrial applications with high reliability requirements.

III. High- and Low-Voltage Switchgear Series

High-voltage switchgear: Covers both gas-insulated and metal-enclosed types, supports voltage levels from 40.5 to 1100 kV, and integrates intelligent monitoring functions.

Low-voltage switchgear: Offers both air-insulated and gas-insulated options, suitable for various current loads, ensuring operational safety and optimized energy efficiency.

Ring Main Unit: Features enhanced insulation performance, making it suitable for underground or high-density urban power grids and reducing the scope of fault impacts.

IV. Cable Branch Box Series

European-style cable distribution box: Features a T-shaped connector design, supports multi-circuit branching, and its fully insulated structure ensures operational safety.

American-style cable distribution box: Centered around a horizontal multi-way busbar, it features load-break plug-in capability to enhance operational flexibility.

Switchgear with Switch: Integrated SF6 load switch or fuse, providing overload protection and fault isolation, suitable for industrial parks and commercial centers.

V. Complete Product Sets and System Integration

Prefabricated complete sets of equipment: Pre-assembled and pre-commissioned at the factory, requiring only basic construction work on-site, thus shortening the delivery cycle.

Intelligent monitoring system: Optional remote diagnostics and real-time data collection features enhance operational and maintenance efficiency.

Modular design: Supports flexible combinations and is adaptable to diverse scenarios, including residential, industrial, and public facilities.

Driven by technological innovation, our product line focuses on energy conservation, consumption reduction, and environmental adaptability, offering a one-stop solution for power engineering projects.
