INFLATABLE DUCT SEALING SYSTEM (IDSS)

New Products / New Technology

Inflatable cable‑duct sealing bags are constructed from a polymer–metal composite and feature high‑temperature, high‑pressure‑resistant waterproof sealing strips on both sides. When the inflation pressure reaches 0.28 MPa, the bag tightly conforms to the inner cable and the outer duct under pneumatic pressure, while the sealing strips fill all gaps, achieving an effective seal. These products are suitable for waterproof sealing of pipelines across multiple industries—including power, telecommunications, urban infrastructure, and petroleum—and with various materials such as steel, iron, concrete, and plastic.

Automatic fire suppression system

New Products / New Technology

The automatic fire suppression system (over‑temperature protection device) is a new, intelligent fire‑extinguishing product. It is manufactured using high‑quality, environmentally friendly industrial materials as base components and employs specialized production processes. This product offers excellent safety, high extinguishing efficiency, and convenient installation and maintenance, while also supporting customized design options. It is the ideal fire‑protection solution for relatively enclosed, unattended small spaces and equipment—such as distribution boxes, meter cabinets, control cabinets, switchgear, charging/battery‑swap stations, and energy‑storage batteries—that pose potential fire hazards.

Smart Humidity-Regulating Sheet

New Products / New Technology

Polymeric smart humidity‑regulating sheets are an innovative composite moisture‑control material that begins absorbing moisture when relative humidity exceeds 55% and releases moisture when it falls below 55%. This keeps the internal relative humidity of equipment typically within the 45–65% range, significantly reducing the conditions conducive to condensation. It is a cutting‑edge material for addressing equipment dehumidification challenges.
