On the turbulent seas, a modern ship is like a floating “smart city.” From the cockpit to the engine room, from the passenger cabin to the communications system, electricity is the critical lifeline. Within this invisible “blood vessel,” TST CABLE’s low-smoke, halogen-free, flame-retardant cable (LSZH) technology is quietly becoming a core guarantee of ship safety.
Why shouldn’t shipboard cables be used casually?
Imagine: An ocean liner is sailing at night when a fire suddenly breaks out in the engine room. Using traditional PVC cables would release large amounts of toxic chlorine gas and thick black smoke—not only suffocating people and making it difficult to escape, but also corroding delicate instruments, causing navigation problems and communication interruptions, with devastating consequences.
The remarkable feature of TST CABLE’s low-smoke, halogen-free cables is that they emit no black smoke or toxic gases when they catch fire, and they are self-extinguishing. Even in a fire, personnel can clearly see the escape route, minimizing damage to equipment and buying precious time for rescue efforts. For ships with enclosed spaces and difficult escape routes, this “green fireproofing” capability is a must!
Industry Trend: International regulations drive green cables into the market
In recent years, the International Maritime Organization (IMO) and the International Convention for the Safety of Life at Sea (SOLAS) have continuously tightened safety requirements for ship materials. In particular, high-risk vessels such as passenger ships, cruise ships, and oil tankers are required to use low-smoke, halogen-free, and flame-retardant cables.
At the same time, the global shipbuilding industry is accelerating its transition to a green and low-carbon future. Many European countries have explicitly mandated the use of environmentally friendly materials in new ships, and China has also proposed promoting halogen-free flame-retardant technology in its 14th Five-Year Plan for the Shipbuilding Industry. It’s safe to say that those who don’t use low-smoke, halogen-free cables risk being excluded from the high-end shipbuilding market.
More importantly, these cables offer enhanced resistance to salt spray, moisture, and corrosion, making them particularly suitable for ships exposed to high humidity and salt environments, resulting in a longer lifespan and lower maintenance costs.
Real Case Study: From Luxury Cruise Ships to Offshore Wind Power
The “Safe Choice” of the World’s Largest Cruise Ship
A world-class luxury cruise ship, slated for its maiden voyage in 2023, carries nearly 7,000 passengers and boasts over 4,000 kilometers of cabling. The ship’s electrical system manager revealed, “We use WDZ low-smoke, halogen-free cables throughout to ensure safe evacuation of passengers in the event of a fire.” The ship successfully passed the EU’s most stringent fire tests, setting an industry benchmark.
China’s “New Standard” for Offshore Wind Power
Not only passenger ships, but also offshore wind power operation and maintenance vessels are following suit. On the mother ship supporting an offshore wind power project in Jiangsu, all power and control cables are equipped with TST CABLE low-smoke, halogen-free cables. “I used to worry about fires causing secondary incidents, but now I feel much more at ease,” said a chief engineer. “Plus, it’s lighter and easier to install than older cables.”
“Secret Upgrades” in the Military Sector
In the military sector, safety demands are even higher. Navies of many countries have adopted low-smoke, halogen-free cables in their new frigates and submarines. Although public information is limited, the industry generally believes that this type of cable can significantly enhance wartime survivability and sustained combat capability.
Future Direction: More Than “Flame Retardant,” More Than “Intelligent”
Today, TST CABLE’s low-smoke, halogen-free cables are no longer a “high-end option” but standard equipment for modern ships. With breakthroughs in domestic material technology, prices have steadily fallen, and even small and medium-sized fishing vessels are beginning to adopt them.
Currently, TST CABLE is exploring integrating fiber optic composites, temperature sensing, and condition monitoring into low-smoke, halogen-free cables to create “smart cables that speak.” For example, these cables can provide real-time warnings for overheating, aging, and other issues, truly transitioning from “passive fire protection” to “active prevention.”
On the vast ocean, safety is no accident. A single cable can determine the fate of an entire ship. TST CABLE’s low-smoke, halogen-free, flame-retardant cables may be relatively unknown, but they are the most reliable “invisible guardians” of modern ships. TST CABLE uses technology to safeguard the bottom line, making every voyage more secure.
