    1. Pillow shape with lip design for IPS rubber bag. Compared with the traditional shape, pillow shape is easier to spread, breathes more smoothly and has fewer folds. During operation, the direct contact and friction of the lip against the inner wall of the oil tank, helps to protect the exteriors of the rubber bag.

    2. Initiated in China, design of different rubber materials for inside and outside is adopted instead of the one rubber material formula. The inside rubber material focuses on improving  the resistance to ozone aging in the air and the air tightness performance, while the outside rubber material focuses on improving oil resistance, heat aging and wear resistance.

    3. In the production process of coated fabric, the automatic calender pressure laminating process is used instead of traditional manual fractioning and coating technology.

    4. In the shaping stage, the integral shaping process is adopted to replace the traditional manual bonding process. The integral shaping process greatly enhances the bond strength and the pressure resistance performance of the rubber bag. Solved the problem of product quality instability caused by the manual production of traditional rubber bag. Completely eliminate leakage problem.

    5. During production, the use of talcum powder and other polluting materials of the traditional process is totally abandoned. In the traditional process, the inevitable use of two types of material will produce pollution to transformer oil. One is ethyl acetate used in the frictioning and coating process of producing the coated fabric, the other is talcum powder used in the vulcanization shaping process. Due to the different processing method, which is completely environment friendly, IPS rubber bag can promise zero pollution to transformer oil.

    6. Professional equipment of independent innovation designed and other advanced equipment in the industry are widely used in the production process, such as automatic rolling machine, laser cutting machine. The consistency of products is ensured by reducing the manual process of the traditional process.
     

  • 1. Shire puts rubber pad between iron core and mounting seat, reducing whole tank vibration caused by vibration of iron core, reducing noise transmission fundamentally.
     

    2. Noise Reduction Effect: Decibel can be reduced by 20%.

  • Oil Storage Bag
    Oil Storage Bag for Transformer Maintenance & Oil Storage Bag for Transportation...

  • 1. Oil Storage Bag for Transformer Maintenance

        Transformer oil storage bag for transformer maintenance and urgent repair can be folded, which are used in transformer routine test and emergency repair to replace iron tank.
     
      It can not only be used together with oil pump for transformer oil filtering in circulation, but also for long time storage of transformer oil.

        Compared with traditional iron tank, oil storage bag can be easily delivered to the site with no need of lifting equipment or large trucks due to its soft rubber material. It shows huge advantages especially in outdoor substation GSU Transformer urgent repair and underground substation maintenance.

    Advatages:

    Easy and fast assembly, convenient maintenance

    ② Insulated material for safe operation at site

    Small size, low weight and easy to transport and carrying, which can reduce labor

    No need of lifting equipment and large trucks

    Resistance of ultraviolet and aging, long service life

    Wide range of working temperature: -40℃—+90℃

    Customization according to clients’ drawings

    2. Oil Storage Bag for Transportation

        Oil storage bag is made of polyurethane material with high intensity, resistance of wear, tear and low temperature. It’s made by high frequency welding or thermal forming after the material cutting. Its mainly applied in temporary and long time storage of gasoline, diesel, jet fuel, industrial grease etc. It can be placed in cars, ships and planes as transportation container.   

    Advantages:

    ① Compared with iron tank, it has light weight, no corrosion and small size after folding. It’s also convenient to assemble & disassemble, transport and fold & unfold with good adaptability, sealing effect and durability  

    ② Cost saving of long-distance transportation with higher volume than iron tank

    Cost reduction of package unloading and material management

    Customized dimension according to the drawings

  • Transformer Noise Damping Products
    Noise damping rubber sheet & Compound noise damping rubber plate & Noise damping rubber pad...

  • Noise is one of the three major environmental pollution issues.

    Noise is harmful to peoples physical and mental health, which may lead to low working efficiency and even safety accidents.

    Causes of Transformer Noise

    1. Silicon sheet vibration caused by magnetostrictive effect.

    2. Core vibration caused by electromagnetic force resulting from magnetic flux leakage between seams of silicon             

      sheet and laminations.

    3. When the load current passes through windings, wall of tank may vibrate due to magnetic flux leakage  

       caused by loading current.

    5. Owing to the changes of resonant frequency and mechanical stress after core heating, noise will become louder along with the rising of temperature.

    New material:We do research on polymer damping materials, compose different damping material together and finally make compound damping material, which can increase damping effect and inhibit the transformer noise

    Advantages of high polymer damping materials:

    Remarkable vicoelasticity and large internal friction, which can achieve high damping;

    Various material according to specified requirements for molecular designing.

    Great ability of processing to form various shapes

    Shire integrated transformer noise reduction plan and products:

     

    Noise damping rubber sheet between core

    Compound noise damping rubber plate for Inner, outer wall of tank

    Noise damping rubber pad under the base of active part.

    Key Product—Noise Damping Rubber Sheet for Core

    1. High performance of hot oil resistance and long service life.

    2. Polished surface design for convenient movement and stacking of core.

    Performance

    1. The only qualified rubber sheet supplier of Siemens in China to substitute German products.

    2. More than 5 dB noise reduction.
