Key Advantages:

1. The TSTY box-type substation shell adopts 7 layers of nano-composite coating and one-piece shell processing technology, with excellent anti-corrosion performance (more than 20 years) and wide temperature range adaptability from -40℃ to +40℃. Through modular structural design and customizable appearance color, it can achieve organic integration with the urban landscape while ensuring power supply stability.

2. Intelligent manufacturing：Full-process automated assembly/welding/testing (each link is equipped with high-precision sensors and testing equipment), production efficiency increased by 60%, product consistency reached 99.8%. Real-time collection of 500+ production parameters, dynamic optimization of AI algorithms, customized order delivery cycle shortened by 40%, meeting the customized needs of different customers. Annual output 30,000 units.

3. Automatic operation

The protection system uses substation integrated automation devices, which are installed in a decentralized manner, and can remotely set operating parameters, control the humidity and temperature in the box, and meet unattended requirements.

4. Customized services:

Deeply involved in 20+ State Grid benchmark projects, adapting to industrial/commercial/municipal multi-scenario needs, and providing customized design and manufacturing services.
