4. Advantages vs. Standard Sleeving
| Feature | Benefit |
|---|
| Internal Silicone Layer | Seamless bonding prevents fluid ingress; maintains dielectric integrity |
| External Fiber Braid | Enhanced cut/tear resistance; withstands mechanical stress |
| Adhesion-Free Design | Easy installation without adhesives; reusability for maintenance |
| Halogen-Free | Non-toxic fumes during fire; complies with eco-regulations (IEC 60754) |
Note: For customized sizing, certifications (e.g., UL, TÜV), or test reports (dielectric/thermal aging), consult manufacturer datasheets. Suitable for replacements in legacy systems requiring MIL-DTL-23053/5 or IEC 60684 standards.
