SHIRE TECH has successfully developed integral-forming rubber bag for power transformers

SHIRE has become the only enterprise in China and the third in the world who owns the rubber bag integral forming technology with world leading performance.

Recently, SHIRE TECH self-developed integral-forming rubber bag for power transformer has passed a full set of tests, and the results show that its performance has reached the international leading level, which indicates that China's power transformer rubber bag with world leading performance has completely broken the foreign monopoly.

As the core component of transformer, the integral-forming rubber bag for power transformer is used to compensate the volume expansion or contraction of insulating oil caused by temperature change, and to separate the insulating oil from air and water to prevent the moisture absorption and oxidation of the insulating oil. For a long time, the core technology of rubber bag for power transformer is monopolized by foreign manufacturers. The imported products are expensive and the delivery always takes a long time, which seriously restricts the construction of electric power projects in China. Since the 1970s, Chinese enterprises began to develop power transformer rubber bag, but there’s not breakthrough of the core technology. The product material and manufacturing technology are backward, and its performance can not meet the long-term reliable operation requirements of transformer.

SHIRE TECH, since its establishment, has been focusing on the pain spot of China's electric power industry. By collaborating with Nantong Henrui New Polymer Material co., Ltd., breakthroughs have been made in material and key process technology by independent innovation. With the development of "air side rubber - fabric framework - oil side rubber" 2 different rubber material coated fabrics structure to successfully create world first 2 different rubber material coated fabrics integral-forming rubber bag , the products meet the requirements of the service life of 30 years, and the performance reached the international leading level.

SHIRE TECH L-IPS (long life, Integral-forming Pillow Shape) rubber bag not only replaces imported products comprehensively and rapidly at domestic market, but also exports abroad in large quantities. The product is widely supplied to ABB, Siemens, GE, Hyundai, Hyosung, Pennsylvania Transformer and other internationally renowned power transformer manufacturers, winning the general recognition of customers.

In the future, under the group's mission of "focusing on problems concerned by customers, providing innovative products, services and solutions, and continuously creating the maximum value for customers", SHIRE TECH will stick to innovating independently and promoting the progress of the industry.
