Rotary transformers, as electrical equipment with high precision and stability requirements, are widely used in various industrial automation and control systems. Especially in fields such as electric motor drive, robotics, aerospace, etc., rotary transformers have extremely high requirements for environmental adaptability. To ensure its stable operation under harsh conditions such as long-term, high temperature, high pressure, and vibration, coil wrapping and sealing treatment are crucial.
Silicone sealant | Coating for coil wrapping of rotary transformer
The challenge of wrapping the coil of a rotary transformer
The coils of a rotary transformer typically require protection through encapsulation or coating to address the following challenges:
High temperature environment: Transformers may experience temperatures above 150 ° C during operation, and it is required that the sealing material can work stably for a long time to prevent material aging and failure caused by temperature fluctuations.
Good permeability and wrapping: In the coil wrapping of the rotary transformer, it is required that the sealant can effectively penetrate into the gaps between the coils, ensuring that there are no missed areas and providing uniform protection.
Resistance to mechanical and thermal shock: Rotary transformers are often exposed to environments of vibration, shock, and thermal changes, so their sealing materials must be able to alleviate the stress caused by mechanical and thermal shock.
Solution
RTV SIPC 1823 neutral dealcoholized silicone adhesive sealant is a flowable moisture absorbing cured silicone gel that forms a flexible rubber body after curing, fully complying with the EU ROHS directive requirements. During the curing process, alcohol substances are released, which are non corrosive to materials such as polycarbonate (PC) and copper. They have good adhesive and sealing properties for the vast majority of materials, protecting electronic products in a stable state under harsh conditions.
