무엇인가요 열수축 튜브?
Heat shrink tubing is a specially designed polymer tube that shrinks when heated.
When exposed to heat, the tubing contracts tightly around:
- 전선
- 전기 터미널
- Cable joints
- 커넥터
- 접합
This creates a protective insulating layer around the connection.
Heat shrink tubing is commonly used for:
- 전기 절연
- 방수 밀봉
- Wire bundling
- Mechanical protection
- 스트레인 릴리프
It is available in many:
- Sizes
- Colors
- 재료
- Wall thicknesses
- Shrink ratios
to suit different applications.
열수축 튜브의 작동 원리
Heat shrink tubing is manufactured through a process that expands the tubing material and gives it “memory.”
When heat is applied, the material returns to its original smaller size.
This shrinking action creates:
- Tight insulation
- Secure sealing
- Improved wire protection
Understanding Shrink Ratios
Shrink ratio refers to how much the tubing can shrink compared to its expanded size.
Common shrink ratios include:
| 수축률 | 설명 |
|---|---|
| 2:1 | Shrinks to half its original diameter |
| 3:1 | Greater flexibility for varying sizes |
| 4:1 | Large shrink capability for irregular shapes |
Higher shrink ratios are useful for connectors and uneven cable assemblies.
