I.Cases of Earthquake Relief Work
In the afternoon of May 12, 2008, a strong earthquake of magnitude 7.8 happened in Wenchuan County of Sichuan Province. In the provinces or cities like Sichuan, Chongqing, Shaanxi and Gansu, part of electric facilities were damaged to various degrees.
From May 12 to 14, our China XD Group’s sales companies in Chengdu, Lanzhou and Chongqing continuously received the calls crying for help from the customers in Sichuan, Gansu and Chongqing, which said that the equipment of local transformer substations were damaged and caused power cut so they needed emergent relief. After receiving the calls, the XD Group’s leading team of earthquake relief delegated wok immediately by organizing the Xi’an XD Transformer Co., Ltd., Xi’an XD High Voltage Porcelain Co., Ltd., Xi’an XD Power Capacitor Co., Ltd. and XD Lightning Arrester Co., Ltd. to prepare relief equipment and spare parts with the fastest speed and inform emergency service team members to get ready to leave at any time.
On May 14, the first group of electric equipment for earthquake relief sent to the disaster areas by China XD Group started to be transported. These equipments were valued about RMB 800,000 Yuan, including: 4 bushing shells of 220kV transformer, 1 bushing shell of 110 kV transformer and the spare parts, which were sent to Zaoyang 220kV Transformer Substation at Biri Town, Wen County, Longnan Region of Gansu Province; 3 capacitive
pressure transformators of 500kV, four 220kV capacitor voltage transformers and three 500kV zinc-oxide arresters, which were sent to Zipingpu Transformer Substation at Dujiangya, Sichuan Province.
 
The First Record of XD Group’s Emergency Repairs:
1. XD Zipingpu Hydropower Station in Sichuan
Zipingpu Key Water-control Project, located in the Minjiang River and at the juncture of Dujiangyan City and Wenchuan County, is one of the ten symbolic projects which were first started in China’s west development.
In the evening on May 13, Chengdu Branch of XD Sales Company received the call from Zipingpu Earthquake Relief Headquarter which cried for a group of capacitive
pressure transformators of 500kV and a group of lightning arresters of 500kV. Under the powerful command of the relief leading team, every company of XD Group prepared the materials through the night and sent them out at the night of May 14. They overwhelmed all the difficulties on the way and delivered the products needed to the construction sites on May 15.
Ma Xiaofeng, the manager of Chengdu Branch, leading 7 people including Li Bin and Zhang Ke of Xi’an XD Power Capacitor Co., Ltd., Yan Yong of Xi’an XD Lightning Arrester Co., Ltd., etc, hurried to Dujiangyan Zipingpu Hydropower Station and did the emergency work, such as installation and adjustment. On their way, they received again the call from Zipingpu Company which asked for help. Because the Japan Mitsubishi was not willing to provide their service on the site, the damaged 500kVGIS could not be repaired. They hoped our company could send experts to the site. Hearing this, Tian Yian, the general Manager of XD Sales Company contacted the leaders of Xi’an XD High Voltage Apparatus Co., Ltd. According to the Group’s earthquake relief work leaders’ instruction, they would try to meet all the customers’ needs with every effort at any cost. Xi’an XD High Voltage Apparatus Co., Ltd. organized quickly a rush-repairs group with Wang Jianxi, the assistant chief engineer, as the leader. In the early morning of May 16, at the risk of aftershocks, the group members flied to Chengdu from Xi’an, Shijiazhuang and Xiamen, and arrived at Zipingpu construction site at 5:00 pm.
The rush-repairs group began to examine the site as soon as they got there. They studied the repairs plan with related workers and did the tense repairs and examinations through the night. Everybody carried forward the spirit of no fear of fatigue and continuous working and struggled in the workshops at the risk of so many aftershocks. Till 3 o’clock in the midnight, they finished the preplanned work. The next day, they did trace monitoring on the site. At 17:52 on May 17, Zipingpu Hydropower Station restored power supply for Sichuan electric network and by 22 o’clock, 3 machine sets are generating online. Up to May 19, the hydropower station had gone through 24-hour operation at full load.
Zipingpu Hydropower Station’s being combined to the grid effectively promoted the discharge capacity of Zipingpu dam, which played an important role in keeping the safety of the dam, the water supply of Chengdu Plain and the electricity supply for the earthquake relief work in Sichuan.
During the earthquake relief work at Zipingpu Hydropower Station, our company sent 2 trucks into Dujiangyan, the harder-hit area, from Chengdu for 5 times in 3 days, and 16 persons went into the site of relief one after another. Through the task, we could not only finish quickly the replacement service of our XD Complex’s own products, but also fully reflect our XD Group’s social responsibility. Thanks to our strong technical expertise, we had the readiness to take over responsibility and accomplished the rush repairs of 500kVGIS delegated by Zipingpu Company. We won honour for China XD Group and great acclaim from Sichuan provincial government, the Ministry of Water Resources and Zipingpu Hydropower Station as well.
 
The First Record of XD Group’s Emergency Repairs:

From the night of May 13 when XD Company received the calls for relief from the Zipingpu Earthquake Relief Headquarter to 17:52 on May 17 when Zipingpu Hydropower Station restored power supply for Sichuan electric network, in the 4 days, our XD Group sent 2 trucks of relief power equipment into the harder-hit area Dujiangyan from Xi’an and 16 emergency employees went to the site of relief. We could not only finish quickly the replacement service of our XD Company’s own products, but also, thanks to our XD’s strong technical expertise, accomplished the rush repairs of 500kVGIS delegated by Zipingpu Company with the readiness to take over responsibility, which fully reflects our XD Group’s style of central enterprise with the courage to shoulder social responsibility.

And they hoped the goods could be delivered within 30 days. After our exchanging information with them, various companies declared positively that they would try hard to deliver the relief goods.
On May 18, arriving at the construction site, we saw the whole substation was damaged seriously with the
collapsed main control building, displaced 220kV extra voltage transformator, collapsed and broken arc-extinguishing chamber of 220kV breakers (including 3 from ABB and 2 from Henan Pinggao Electric Co., Ltd.),2 groups of fallen isolating switches (from Xi’an XD High Voltage Apparatus Co., Ltd), other 15 groups looked sound, crooked pressure transformator (from Xi'an XD Power Capacitor Co., Ltd.), leaning and oil-leaking current transformator (from Liling Electric Co., Ltd.) and crooked and collapsed lightning arresters (from Fushun High Voltage Porcelain Co., Ltd). After recording the 220kV products in detail, we examined the 110kV products of which the current transformators were damaged the most seriously with 8 of them crooked and leaked oil. Every one was deeply honored to see two LW25-126 breakers produced by XD Complex stood there safe and sound. After the inspection, we went to Chongqing to sign technical agreement according to what Chongqing Electricity Company asked for.
