Low-smoke, halogen-free, flame-retardant cable: the “green guardian” of large data centers
In recent years, with the acceleration of global digitalization, the safety and environmental performance of data centers, the “heart of the digital world,” has drawn significant attention. Within this sector, a technology known as low-smoke, halogen-free, flame-retardant cable (LSZH) has quietly become a new industry favorite. It not only addresses the environmental challenges of traditional cables but also provides a key guarantee for the safe operation of data centers.
Why do data centers need low-smoke, halogen-free cables?
When burned, traditional cables release large amounts of toxic gases (such as chlorine and hydrochloric acid) and produce thick, black smoke, posing a fatal threat to personnel evacuation and equipment protection. The unique feature of low-smoke, halogen-free cables is that they produce virtually no harmful gases and extremely low smoke concentrations. This makes them an essential requirement for data centers, where densely populated areas and sophisticated equipment are located.
Furthermore, data centers have high energy consumption and high maintenance costs, and any fire incident can result in significant losses. The flame-retardant properties of TST CABLE’s low-smoke, halogen-free cables can effectively slow the spread of fire, buying valuable time for emergency response while also reducing the risk of equipment corrosion and data loss after a fire.
Industry Trend: Prioritizing Green and Safety
Currently, the global data center industry is moving towards green and sustainable development. Tightening environmental regulations such as EU RoHS and REACH, along with the drive for carbon neutrality, are forcing companies to re-evaluate their material choices. Low-smoke, halogen-free cables, due to their halogen-free, low-toxicity, and recyclable properties, have become the preferred material for meeting international environmental standards.
Furthermore, with the explosive growth of technologies like AI and cloud computing, data center scale continues to expand, significantly increasing cabling complexity. The lightweight design of TST CABLE’s low-smoke, halogen-free cables (lighter and more flexible than traditional PVC cables) also simplifies installation and improves space utilization, further meeting the construction requirements of high-density computer rooms.
Real-World Case Study: From “Passive Compliance” to “Active Choice”
An International Cloud Service Provider’s Green Transformation
In 2023, a leading global cloud service provider fully adopted TST CABLE’s WDZ series low-smoke, zero-halogen cables in its new Asia data center. The project manager stated, “We not only need to meet local environmental regulations, but also aim to provide our customers with a ‘zero-risk’ physical environment.” By using low-smoke, zero-halogen cables, the data center reduced hazardous gas emissions from fire incidents by 90% and successfully achieved LEED green building certification.
European Metro Tunnels: “Cross-Border Inspiration”
European railway systems adopted low-smoke, zero-halogen cables as a mandatory standard as early as a decade ago, and this experience has been leveraged by the data center industry. For example, a financial data center in Frankfurt, Germany, referenced cable selection from metro tunnels during its initial design phase. The performance of the low-smoke, zero-halogen cables was verified through simulated fire tests, ultimately achieving the goal of “restoring business within 48 hours after a fire.”
Future Outlook: From “Material Upgrade” to “System Innovation”
Despite significant progress in low-smoke, zero-halogen cables, the industry is still exploring deeper innovations. For example, TST CABLE is developing nano-coating technology to further enhance its high-temperature resistance by adding flame retardants to the cable surface. They are also experimenting with embedding smart sensors into the cables to monitor parameters like temperature and humidity in real time, providing early warning of potential risks.
It is foreseeable that with technological advancements and cost reductions, TST CABLE’s low-smoke, halogen-free cables will become standard equipment in data centers. Companies that pioneer green materials will not only gain an advantage in regulatory compliance but also earn customer trust with their dual “safety + environmental” credentials.
In the digital age, every heartbeat of a data center impacts trillions of dollars in economic activity. Choosing TST CABLE’s low-smoke, halogen-free, flame-retardant cables is not only a reverence for technology, but also a commitment to the future—protecting every beat of the digital world in a safer, cleaner way.
