Description
Crepe Paper Tubes is made of electrically wrinkled insulating paper processed by a special process. It is widely used in key parts such as transformer conductor support, coil isolation, lead protection and internal insulation of casing.
| Serial Number | Performance | Unit | Requirements |
|---|---|---|---|
| 1 | Inner diameter (D1) | mm | 4 - 50 |
| 2 | Inner diameter tolerance | mm | ±0.5 |
| 3 | Wall thickness (S) | mm | 1 - 6 |
| 4 | Outer diameter (D2) | mm | D1 + 2S |
| 5 | OD tolerance | mm | 1 |
| 6 | Length | mm | 1000 - 1500 |
| 7 | Length tolerance | mm | 20 |
| 8 | breakdown voltage in oil | kV | 15(S = 1) 20(S = 1.5) 35 (s≥2) |
Main features:
- High dielectric strength: ensure electrical insulation safety and prevent breakdown.
- Excellent flexibility and wrapping: suitable for wrapping special-shaped or curved wires and fitting tightly.
- Good oil absorption performance: can quickly absorb insulating oil and improve the overall stability of the insulation system.
- Strong mechanical support: the paper tube structure provides good support to prevent lead vibration and displacement.
Product advantages
1.High strength and flexibility at the same time
2.Good compatibility with liquid insulation materials used in transformers
3.The fineness, elasticity and low thickness of the base paper result in high electrical strength of the final product
4.Used for distribution transformers, which can be 100% oil-immersed in a short time
