Herch transformer winding fiber optic temperature monitor has been successfully applied to two 220KV transformers exported to Egypt by TBEA Hengyang Transformer Co., Ltd. The user is EETC, an Egyptian power supply company. The picture shows the application site of the product in Egypt. The successful implementation of this project provides a solid foundation for the marketing of photovoltaics in Egypt.

Egypt's EETC 500 KV transmission line project was signed by Chinese President Xi Jinping and Egyptian President Cessi. It is the first successful contracted project under Sino-Egyptian capacity cooperation and the largest transmission line project with the highest voltage level in the country.
