Hoonsun Launches EX Series Explosion-Proof Cable Glands (Tinned Brass): Solid Safety Protection for Hazardous Industrial Sites
With nearly 20 years of experience in cable connection solutions, Hoonsun is pleased to announce the official launch of its new EX Series explosion-proof cable glands, made of tinned brass. Designed for hazardous industrial environments where safety and reliability are non-negotiable, these glands integrate explosion-proof, waterproof, corrosion-resistant and easy-to-install features, directly addressing key connection pain points for customers in new energy, marine, chemical and rail transit industries.
In chemical, oil and gas, marine engineering and other sectors, electrical equipment often operates in harsh conditions—high humidity, salt spray corrosion, and even explosion risks. Traditional cable glands commonly suffer from poor sealing, weak corrosion resistance, and failure to meet explosion-proof standards. These issues not only cause equipment downtime and higher maintenance costs, but also pose serious safety hazards. Drawing on years of on-site experience and customer feedback, Hoonsun's R&D team developed the EX Series to solve these industry-specific problems effectively.
Key Advantages of Hoonsun EX Series: Safe, Durable, Easy to Use
Every EX Series explosion-proof cable gland (tinned brass) has passed strict testing and certification, with distinct core advantages:
1. Full Explosion-Proof Certifications for Enhanced Safety
The EX Series complies with explosion-proof standards Ex eb IIC T4 Gb and Ex tb IIIB T135°C Db (in line with national standard GB 3836-2021), suitable for Zone 1 (gas hazardous area) and Zone 21 (dust hazardous area) respectively. All products have obtained CE certification and meet EU RoHS 2.0 (2011/65/EU) environmental requirements, adhering to global safety and environmental norms. They provide reliable protection for electrical equipment in flammable, explosive and dusty environments, effectively preventing safety accidents caused by cable connection failures.
2. IP68 Waterproof & Dustproof, All-Round Protection
Equipped with high-quality NBR (nitrile butadiene rubber) seals and an integrated sealing structure, the product achieves IP68 protection level. It can effectively block water, dust and oil from entering cables and equipment, suitable for harsh scenarios such as humid marine projects, dusty workshops and outdoor operations in rainy weather. Note: Long-term underwater immersion requires matching with special waterproof cables; under standard working conditions, it ensures stable equipment operation and avoids short circuits and malfunctions.
3. Tinned Brass Construction: Corrosion-Resistant & Long-Lasting
Made of high-quality tinned brass, the EX Series offers excellent mechanical strength, impact resistance and wear resistance—far better than ordinary nylon cable glands. The tin plating further enhances corrosion resistance, effectively withstanding salt spray, acid, alkali, alcohol, grease and common solvents. It is particularly suitable for chemical plants, coastal areas and marine operations. The product can operate stably at -40°C to 120°C (short-term peak temperature up to 150°C, lasting no more than 10 minutes), with a service life twice that of ordinary nylon glands, significantly reducing replacement and maintenance costs.
4. Flexible Installation & Wide Compatibility
The EX Series supports multiple thread specifications, including metric M-thread, PG-thread, G (PF)-thread and NPT-thread, compatible with most equipment interfaces worldwide. The optimized clamping ring can firmly fix cables of different specifications without damaging the cable sheath; installation is fast and simple, no special tools required, effectively saving on-site construction time. The product is available in two colors: black (RAL 9005) and light grey (RAL 7035), suitable for different application scenarios and brand visual needs.
Widely Used in Multiple Industries, Quality Proven in Practice
The EX Series has been put into practical application in many key industries and received consistent praise from customers:
In marine and rail transit fields, its explosion-proof, tinned brass-enhanced corrosion resistance and vibration resistance ensure stable operation of ship electrical systems and railway signal equipment under continuous salt spray erosion and long-term vibration. In chemical and petrochemical industries, it provides safe protection for cable connections in Zone 1 hazardous areas (flammable gas environments), helping enterprises meet strict safety production standards. In the new energy sector, it is widely used in PV inverters, energy storage cabinets, motors and other equipment, adapting to high-temperature and complex outdoor working conditions and ensuring safe and stable operation of equipment.
A relevant person in charge of Hoonsun said: "The launch of the EX Series is the result of us listening closely to customer needs. For nearly 20 years, we have always adhered to the principle of quality first and customer foremost. This product not only reflects the company's technical strength in explosion-proof and anti-corrosion fields, but more importantly, it safeguards the safety of industrial sites and reduces downtime losses for customers."
To meet customers' personalized needs, Hoonsun also provides customized services for the EX Series tinned brass explosion-proof cable glands, including special specification development and batch customization. Relying on global channels such as the new OKKI website, Alibaba International Station and various social media platforms, we ensure that customers around the world can obtain the products quickly, while providing timely pre-sales consultation and after-sales support.
