Explore our specialized metal cable glands engineered for marine platforms, naval vessels, and offshore energy infrastructure.
In the global maritime and offshore industries, electrical integrity is paramount. Operations spanning commercial shipping, naval vessels, floating production storage and offloading (FPSO) units, and offshore wind platforms require continuous, uninterrupted power and signal transmission. At the heart of these complex electrical systems are metal cable glands. Acting as the critical interface between cables and enclosures, these components must secure, seal, and protect wiring against the most hostile environmental conditions on Earth.
The marine environment presents a unique cocktail of destructive forces: high salinity, constant moisture, extreme temperature fluctuations, mechanical vibrations, and exposure to corrosive chemicals and oils. Standard industrial cable glands fail rapidly under these conditions, leading to water ingress, short circuits, and catastrophic system failures. Consequently, marine-grade metal cable glands—primarily constructed from nickel-plated brass or marine-grade 316L stainless steel—are non-negotiable standards. They ensure absolute ingress protection up to IP68/IP69K, strain relief to prevent cable pull-out under heavy sea states, and electromagnetic compatibility (EMC) shielding to protect sensitive navigation and communication instruments from interference.
Engineered with heavy-duty neoprene or silicone seals to withstand continuous immersion and high-pressure washdowns on open vessel decks.
Fully compliant with ATEX, IECEx, and UL guidelines for hazardous zones common in offshore oil and gas drilling operations.
Integrated 360-degree grounding rings for armored cables, shielding critical communication and radar systems from electromagnetic noise.
Marine and offshore vessels are dynamic environments. Cables run through bulkheads, decks, engine rooms, and exposed mastheads. Each area demands a tailored sealing solution to guarantee safety and compliance.
The rapid expansion of offshore wind farms requires robust electrical connectors capable of enduring constant aerodynamic vibrations and high salt mist. Metal cable glands installed in wind turbine nacelles and offshore transformer substations secure heavy-duty power cables. The anti-bending design prevents fatigue and strain on the cable cores, ensuring continuous power transmission to the mainland grid.
On oil platforms, hazardous gases are a constant presence. Cable entries into control panels, motors, and instrumentation boxes must be flameproof and explosion-proof. Armored metal cable glands provide a double-compression seal that seals both the inner and outer cable sheaths, containing any potential internal explosion and preventing gas migration through the cable run.
Naval ships are dense networks of electronic systems. Radar, sonar, weapons control, and communication cables run side-by-side. Our EMC-compliant nickel-plated brass glands provide a continuous low-impedance connection between the cable screen and the metal enclosure, neutralizing electromagnetic interference (EMI) that could compromise naval operations.
Subsea exploration and monitoring require equipment to withstand immense hydrostatic pressures. Custom-engineered stainless steel glands are deployed on underwater cameras, sensors, and ROVs (Remotely Operated Vehicles), maintaining water-tight integrity at depths of thousands of meters.

Company relocated again, new brand, appearance is more bright and international.
The company was upgraded and the company name was changed to Zhejiang Hoonsun Cable Gland Co., Ltd.
The factory has expanded, with over 120 employees and over 200 production equipment, and has vigorously expanded into other industries such as the photovoltaic industry.
Choosing the right material for offshore cable glands can mean the difference between a system that lasts decades and one that fails in months. Marine engineers typically evaluate two primary metals:
Nickel-plated brass offers an exceptional balance of mechanical strength, electrical conductivity, and corrosion resistance. The nickel plating acts as a sacrificial barrier, protecting the underlying brass from oxidation and galvanic corrosion when in contact with steel enclosures. It is widely used in deck machinery, vessel engine rooms, and dry areas of offshore platforms.
For direct, continuous exposure to seawater, splash zones, and highly corrosive chemical environments, Stainless Steel 316L is the gold standard. Containing molybdenum, 316L steel resists pitting and crevice corrosion caused by chloride-rich marine atmospheres. It is ideal for open-deck installations, subsea equipment, and LNG carriers.
The marine and offshore sector is undergoing a massive digital transformation. With the rise of the "Smart Ship" and automated offshore platforms, the demand for high-speed data transmission and fiber optic cabling has surged. This shift has forced cable gland manufacturers to innovate. Modern metal glands are now designed to house hybrid cables (combining power and fiber optics) while maintaining strict IP68 seals. Furthermore, there is growing interest in integrated sensor technology within cable entries to monitor temperature and moisture levels, alerting crew members to potential seal degradation before failure occurs.
The company currently has more than 120 employees, more than 200 production equipment, and is equipped with a professional sales and management team, committed to improving production efficiency and product quality.
