borosilicate glass tubes in Transformer

High borosilicate glass tubes (specifically 3.3 expansion) are utilized in transformers primarily as oil level gauge indicators due to their high thermal shock resistance, chemical durability against transformer oil, and excellent optical clarity for monitoring. These tubes typically operate within

for monitoring and possess high mechanical strength and electrical insulation properties.

• Primary Application: Used as oil level gauge tubes in transformer tanks for visual monitoring.
• Key Properties:
  • Thermal Stability: Excellent resistance to temperature changes, ensuring the tube does not crack due to heating/cooling cycles.
  • Chemical Resistance: Highly resistant to transformer oil corrosion.
  • Transparency: High clarity for easy monitoring.
• Specifications: Often available in diameters from 30mm to 50mm, with specific, precise, and durable manufacturing.
• Other Applications: While the main transformer use is for oil monitoring, borosilicate tubing is also used in high-intensity lighting products and electronics.

These tubes are critical for maintaining the operational safety of transformers by allowing engineers to monitor oil levels, which are essential for insulation and cooling.
