3 GE in China GE (NYSE: GE) is Imagination at Work -- a diversified global infrastructure, finance and media company that is built to meet essential world needs. From energy, water, transportation and health to access to money and information, GE serves customers in more than 100 countries and employs more than 0,000 people worldwide. The company traces its beginnings to Thomas A. Edison, who established Edison Electric Light Company in In 1892, a merger of Edison General Electric Company and Thomson-Houston Electric Company created General Electric Company. GE is the only company listed in the Dow Jones Industrial Index today that was also included in the original index in GE started doing business in China as early as 1906 and was considered one of the most active foreign companies in the country at the time. In 1908, the first GE light plant was built in Shenyang. GE acquired Anderson, Meyer & Co. in 1934 and started to provide installation and repair services of imported electric equipment in China. All of GE's industrial businesses have set up operations and established over 50 legal entities in China with more than 13,000 employees. Its financial services sector is also seeking business opportunities as WTO opened China market. Industrial Solutions GE Industrial Solutions division from GE Energy Group, a global leading provider in power distribution, offers a wide range of products including medium and low voltage power distribution equipment and components, and motor and control systems that are safe, reliable and perform excellently.

4 Introduction Shanghai GE breaker Co., Ltd. has launched a new SecoVac VB2 Type 12kV series vacuum circuit breakers (Briefed as VB2), which are pieces of apparatus for indoor installation. The products conform to the GB1984 standards (equivalent to IEC ) as well as DL403 standards, and become the optimal choice for control and protection in HV Transmission and distribution system. In particular, the apparatus is applicable for places requiring frequent operation. The installation of VB2 breaker inside switchgear may be alternatively withdrawable type or fixed type. Product Type VB2-12 / T Mounting mode:z - withdrawable type; G - fixed type Rated breaking current for short circuit (ka) : 25, 31.5, 40 Rated current (A) :6, 1250, 1600, 2000, 2500, 3150, 4000 Spring-Operating Mechanism Rated voltage (kv) :12 Vacuum circuit breaker The breaker ready for placing in the cabinet Testing position of the breaker in the cabinet Environmental data Working position of the breaker in the cabinet The ambient air temperature does not exceed 40 C and its average value, measured over a period of 24 h, does not exceed 35 C. The minimum ambient air temperature is -25 C (storage and transport is allow at C). The alitiude does not exceed 1000m. The conditions of humidity are as follow: - the average value of the relative humidity, measured over a period of 24 h, does not exceed 95%; - the average value of the water vapour pressure, over a period of 24 h, does not exceed 2.2 kpa; - the average value of the relative humidity, measured over a period of one month, does not exceed 90%; - the average value of the water vapour pressure, over a period of one month, does not exceed 1.8 kpa. During the period of high humidity, when the temperature drops sharply, pay attention to preventing condensation. Earthquake intensity is no more than 8 degree. The ambient air is not significantly polluted by dust, smoke, corrosive and/or flammable gases, vapours or salt. Storing place free from fire, explosion, chemical corrosion and heavy shakes. 1

5 Characteristics and Advantage High-end 3-D computer-aided design (Pro-Engvineer) and dynamic simulation optimal design (Pro-Mechanical) Lessening partial distribution and local overheat to minimum by optimizing electromagnetic field distribution. World leading-edge miniature interrupter chamber applying axial rotating magnetic field vacuum interrupting principle, with the extremely stable breaking performance. Perfect insulation performance, with more creeping distance and electrical clearance than requirements of IEC and GB standards, pass the condensation test successfully, which is applicable for operation under harish environment. With reliable grounding mode, which ensures earthing continuity of breaker form working position to test position. Pass the temperature rise test under 110% rated current. 1. Vacuum arc-extinguish chamber 2. Radiator (for 2500A and above) 3. Insulating hood 4. Switching-in spring 5. Switching-out spring 6. Contactor spring 7. Main driveshaft 8. Insulating rod The closing spring charging mechanism with exellent performance is applied in the VB2 breaker. Modular design for multi-uses and the main parts are reasonable arranged, which make the operating mechanism simpler and performance more stable. The whole mechanism consist of three modules: energy-charging module, closing module and triping module. Each module can be assembled respectively and mounted on to the mechanism together with bolts. The energy-charging module is composed of two-level worm gears, super cluth and closing spring, which be more compact and delicate. Besides power operating energy-charging device, the manual operating device is provided. Auto-reclosing can be realized for all VB2 breakers. 2
