Key Features

Comewill's transformer products are designed and manufactured with full consideration for safety, reliability, and economy. Our 35kv Three-Phase Oil-Immersed Transformer provides stable power guarantee for various complex working conditions:

Safe, fire-resistant, and pollution-free: It can operate directly in the load center without the need for additional fire isolation measures.

High mechanical strength: It has strong short-circuit resistance, effectively suppresses partial discharge, ensures thermal stability, and extends equipment service life.

High cooling efficiency: Using forced air cooling technology, allowing the equipment to operate safely under overload conditions.

Exquisite surface treatment technology: After multiple processes such as degreasing, rust removal, sandblasting, and coating, it has excellent moisture resistance and is particularly suitable for high humidity and dusty environments such as metallurgy and petrochemicals.

Environmentally friendly maintenance free: The product itself has flame retardant and explosion-proof characteristics, and is designed as a maintenance free structure, reducing the cost of later use.

Compact and lightweight structure: Small in size and lightweight, easy to transport and install on site.

Precise and stable positioning: The iron core and oil tank adopt a fixed structure, effectively preventing displacement during transportation and ensuring the long-term stability of equipment operation.

Efficient iron core design: High quality and low loss silicon steel sheets are used, and multi step oblique joint technology is adopted at the joint of the iron core, greatly reducing no-load loss and noise. The coil is wrapped in paper or self-adhesive transposed wire to minimize load losses, thereby reducing the operating costs of the power grid and users.
