Application of Cork Composite Materials in Power Transformers

Cork composites solutions can play a vital role in transformer design and maintenance. Cork's unique properties, such as resilience, compressibility and load-to-seal, make it ideal for addressing several challenges encountered in the operation of transformers. The versatility of cork solutions can be a game-changer in ensuring efficiency, reliability and longevity.

Key Applications of Cork in Transformers

1. Gaskets for Flanges

Cork gaskets are widely used in transformers to create secure seals between flanges and covers. These areas require materials that can endure mechanical stress, thermal expansion and the presence of transformer oils. By combining cork with rubber, we enhance the flexibility and resistance of the material, providing a dependable solution that minimizes leaks and maintains structural integrity over time.

AMORIM cork rubber sealing materials TD1120, TD1049, TD1310, and TD7000 are widely used in the transformer industry due to their excellent mechanical properties and resistance to transformer oil. Detailed parameters are as follows:

2. Sealants Around Bushings and Valves

In transformers, bushings and valves are critical points of connection and operation, where effective sealing is essential. Cork composite solutions are used as sealants in these areas due to their ability to adapt to irregular surfaces and withstand pressure variations. Their sealing performance helps maintain insulation integrity and prevents unwanted leaks, even under challenging operating conditions.

3. Pads for Vibration and Noise Control

Transformers often experience vibrations generated by the magnetic flux and load cycles. Over time, these vibrations can lead to wear and tear or even structural damage. Cork’s natural damping properties make it an ideal choice for vibration control pads. By absorbing and dissipating vibrational energy, cork reduces noise and extends the lifespan of key components, contributing to smoother operation and lower maintenance costs.

AMORIM cork vibration damping materials VC1047, VC2100, and VC6400 are widely used in vibration damping pads for power transformers due to their excellent vibration damping and noise reduction properties. Detailed parameters are as follows:
