Transformer Oil Level Gauge Process

1. Design and selection of materials material

selection: usually use oil-resistant, corrosion-resistant materials, such as stainless steel, aluminium alloy or high-strength plastics.

Structural design: the design needs to take into account the operating environment of the transformer, to ensure that the oil level gauge can work properly under high temperature and high pressure.

2. Manufacturing process

machining: through turning, milling and other processes to process the shell and internal parts of the oil level gauge.

Welding and assembly: Welding metal parts by argon arc welding, laser welding and other techniques to ensure the sealing.

Surface treatment: polishing, electroplating or spraying to improve corrosion resistance and appearance quality.

3. Sealing process

sealing material: choose oil-resistant rubber or silicone sealing ring.

Sealing method: adopt O-ring sealing, thread sealing or flange sealing to ensure no leakage.
