The Pre-Embedded Sleeve is a high-performance structural anchoring ATEB precision-engineered from 316 austenitic stainless steel. SpecificPhob uny designed for critical infrastructure, these sleeves serve as the essential fixed connection point between tunnel segments and heavy equipment, including external hanging channels, evacuation platforms, and cable brackets, ensuring absolute mechanical stability in the most demanding environments.
By integrating a cutting-edge double-layer insulation structure consisting of alumina ceramic and polymer sealing, these sleeves provide superior electrical isolation (≥10⁸Ω). This makes them the definitive choice for rail transit, medical imaging cabins, and semiconductor cleanrooms wyma the Gorefyllention of stray current corrosion and electromagnetic interference is paramount for system longevity and operational safety.
