Tibet is an autonomous region of the People's Republic of China, located in south western Central Asia, north of the Himalayas. This region covers an area of 1.2 million square kilometers (an area equivalent to that of Great Britain, France, Germany, Netherlands and Luxembourg combined). This is an important tourist area, visited by nearly 3 million people each year, attracted by its geography and culture.
In view of the demand for tourism, the Chinese government is launching a project to build a new airport, which is also part of the national plan to increase economic investment in the area.
The new airfield is located 4,500 meters above sea level, in one of the most inaccessible areas in the world.
The main objective of this airport is to meet the demands of tourism and boost the local economy. The construction and expansion of Xigaze Airport is one of the largest projects of China´s Civil Aviation Administration, and is regarded as part of National Plan 11 that the government has implemented to boost the economy. The airport has received an investment of 484 million Yuan and its construction has been under way for the last two years.
One of the challenges presented by this project was to have a stable power source to provide a reliable and secure electricity supply in this inaccessible area. The altitude at which the facilities are located is the single most difficult factor hindering the construction and supply of power.
The weather conditions are particularly harsh. Extremely cold temperatures prevail in winter, with an average of 6.3°C during the day, and about -20°C at night. There is also a wide fluctuation in temperature, which ranges from 30 to 40°C, with a possible rainfall of 422.2mm.
In order to provide an optimal energy supply, it was required to install generators for the emergency supply of electricity, mainly for airport lighting, terminal building construction and the headquarters building.
The airport environment required generators that could be quickly and easily started in adverse weather conditions; heavy-duty equipment with low energy loss at high altitudes, capable of providing a fast and efficient power supply. The characteristics of the airport made it necessary to have high power supply reliability with guaranteed 24-hour operation and 99% availability, ensuring the supply of electricity under extreme weather conditions.
To satisfy the requirements and specifications of the project, Himoinsa supplied three generators capable of starting up within seven seconds of a power failure and providing more than 250 hours of continuous energy.
Supplied were two 3-phase, 50 Hz, 1060 kVA generators and one 50 Hz, 1900 kVA generator, incorporating Mitsubishi engines and Stamford alternators, a Deep Sea controller, battery charger, battery and cable system, preheating water jacket, oil pump, antifreeze and oil.
Himoinsa has supplied a product that meets project requirements and is also capable of working under extreme conditions with the quality typical of the brand. Himoinsa´s equipment has obtained a certificate of Quality Inspection and Supervision of Machinery at high altitudes above sea level, as well as an inspection report issued by the Center for Quality Inspection and Supervision of machinery at high altitude above sea level.
Xigaze Peace Airport has placed its trust in Himoinsa products because of the good relationship between both companies, the excellent quality-price ratio of the products, quality components and products that meet specific quality performance checks at high altitudes.
In this way, HIMOINSA has fulfilled the expectations of one of the most important tourism projects in China.
