Command centers, radar stations, underground fortifications, weapons depots… these core defense facilities are the “solid fortresses” of national security, operating in extremely complex environments with stringent safety standards. Cable and conduit penetration points are vulnerable areas, requiring simultaneous solutions to multiple challenges, including electromagnetic interference (EMI) protection, shock wave resistance, and penetration prevention. Traditional sealing solutions often fall short in addressing these issues, failing to meet operational requirements. The TST seal MCT permeability sealing system precisely addresses these challenges, offering dual advantages of EMI protection and shock wave resistance to build a crucial line of defense for upgrading defense facility protection.

Core Dual Protection: Fortifying the Lifeline of National Defense Security

The core security of defense facilities relies on absolute control over the electromagnetic environment and shock threats. The TST seal MCT permeability sealing system specifically enhances these two core performance aspects, achieving military-grade protection levels.

High-efficiency electromagnetic shielding protects information confidentiality: The TST seal MCT system adopts an integrated design of a special metal shielding layer and sealing module. Within the 14kHz-18GHz frequency band, its shielding effectiveness reaches 42~63dB, fully complying with the GB/T12190-2006 standard “Measurement Method for Shielding Effectiveness of Electromagnetic Shielding Rooms,” meeting the core performance requirements of Military Standard Class B. This performance effectively blocks external electromagnetic radiation interference, preventing distortion and increased bit error rates in command and radar signals, while also rigorously preventing the leakage of sensitive internal signals, ensuring the security and confidentiality of national defense information transmission from the source.

Superior shock wave resistance withstands extreme impacts: Targeting the threats of shock waves from conventional and nuclear weapons, the system employs a high-strength composite structure. Core components are made of military-grade wear-resistant and pressure-resistant materials, capable of withstanding high-intensity shock wave impacts. Under instantaneous impact, it maintains structural integrity without the risk of cracking or collapse, effectively blocking the spread of shock waves through the shielding points, building a solid protective barrier for internal equipment and personnel.

Comprehensive Protection: Adaptable to Extreme Combat Readiness Scenarios

Defense facilities often operate in extreme environments such as confined spaces, extreme temperatures, and strong corrosion, posing a comprehensive test to the sealing system’s overall performance. The TST seal MCT permeable sealing system offers multiple layers of protection, adapting to long-term combat readiness requirements.

In terms of penetration resistance and environmental adaptability, the TST seal MCT system meets the IP68 waterproof and dustproof standard, effectively blocking the intrusion of moisture, dust, and toxic gases, making it perfectly suited for confined environments such as underground fortifications and weapons depots. Utilizing extreme-environment-resistant composite rubber materials, it can operate stably across a wide temperature range, resisting strong ultraviolet radiation and chemical corrosion, with a service life exceeding 30 years, requiring no frequent replacement or maintenance, meeting the long-term operational requirements of defense facilities.

Regarding stability, the elastic buffer structure effectively absorbs vibrations generated by equipment operation and external impacts. It has passed the IEC 61373 standard vibration and shock test, ensuring that sealing performance does not degrade under complex operating conditions and remains stable and reliable over the long term, preventing protection failure due to vibration.

Modular Design: Balancing Practicality and Continuous Readiness

Defense facilities face confined spaces and complex structures, requiring continuous readiness. Traditional sealing solutions, with their welded installations and downtime maintenance, are ill-suited to these conditions. The TST seal MCT perforation sealing system employs a modular, weld-free design, precisely matching the practical needs of military scenarios.

Installation requires no damage to the existing facility structure, adapting to complex and confined spaces, significantly improving construction efficiency and minimizing disruption to normal facility operation. Later maintenance allows for independent replacement of individual modules, eliminating the need for overall system shutdown and ensuring maximum continuous readiness for defense facilities.

Real-World Verification: A Reliable Choice for Defense Protection

The TST seal MCT perforation sealing system effectively supports defense facility protection upgrade projects, adapting to various defense scenarios such as command centers, radar stations, and underground fortifications. From core performance to practical experience, from environmental adaptability to readiness support, its comprehensive performance effectively improves the protection level of defense facilities, providing reliable support for defense facility protection upgrades.
