Model: ZF8-800/Y5000-63
The ZF8-800 GIS model from XD utilizes proven technologies with a serial double-break 420kV design to enhance operational performance. The key components of the ZF8-800 were designed, developed, manufactured, and tested according to the requirements of 1100kV GIS, ensuring increased operational reliability. Thanks to its modular design, stable operational characteristics, advanced sealing technology, and spring disks for energy storage, it reduces physical space requirements and enhances safety.
Disconnectors and grounding switches are supplied as pre-assembled and tested units. Transportation, installation, and commissioning are simplified, reducing time and project costs.
Main Features

Advantages
- High operational reliability and excellent interrupting capability: The ZF8-800 offers some of the best performance indicators in the industry. Designed, manufactured, and tested based on 1100kV specifications, the ZF8-800 provides the reliability required for complex and demanding transmission applications. Additionally, the ZF8-800 withstands a rated short-circuit current of 50kA and has a unique interrupter design, minimizing the number of required components.
- Reduced time and effort for on-site commissioning: Assembled in large assembly workshops and individually packed as fully functional units, transportation and on-site commissioning are significantly simplified.
- Durability: The ZF8-800 offers an advanced and unique gas-insulated design, ensuring high performance and reliability. With an average annual gas leakage of less than 0.5%, XD GIS is designed for operation exceeding 30 years.
