effect：
The corrugated paper tube in oil immersed transformers is a crucial insulation component inside the transformer, and its quality directly affects the performance and lifespan of the transformer.
Core role and advantages
Wrinkled paper tubes are mainly used for wire wrapping and tap changer leads in oil immersed transformers. Its advantages are very obvious:
Double protection: It is both an insulating material to prevent current leakage and provides mechanical support to protect internal wires from breaking when subjected to compression or bending.
Good flexibility: Compared to traditional phenolic paper tubes, corrugated paper tubes are softer and can be bent freely without breaking, making installation very convenient.
Uniform electric field: When used in combination with transformer oil, the dielectric constants of the two are similar, which can make the electric field distribution inside the transformer more uniform, thereby improving insulation performance.

Product Features:
Mechanical strength: With sufficient toughness, even after bending in an oil immersed environment, it can maintain a certain strength and prevent damage to the wire
