Core Overview
Explosion-proof cable glands are essential safety components for electrical installations in hazardous industrial areas. For global standard hazardous zone projects, ATEX and IECEx dual certification is the core compliance threshold. Hoonsun, a professional manufacturer with 20+ years of industrial fitting experience, provides certified, high-reliability explosion-proof cable glands. The flagship Hoonsun EX-3 explosion-proof cable gland is widely recognized for standardized performance, full certification and cost efficiency.
1. ATEX & IECEx Dual Certification (Global Compliance Standard)
Key Certification Advantages: All Hoonsun explosion-proof cable glands hold valid ATEX 2014/34/EU and IECEx international explosion-proof certifications, fully compliant with EU and IEC hazardous area regulations. The Exd IIC Gb explosion-proof rating supports installation in Zone 1 and Zone 2 explosive gas environments. Auxiliary certifications including CE, RoHS, REACH, UL and IP68 ensure full global project compliance. Supported by ISO 9001 quality system and independent technical patents, product qualification and stability are fully guaranteed.
2. Star Product: Hoonsun EX-3 Explosion-Proof Cable Gland
Product Positioning: Hoonsun EX-3 is the best-selling, cost-effective explosion-proof cable gland, specially designed for high-risk hazardous area electrical installation. With full international certifications, industrial-grade materials and integrated flameproof structure, it is the preferred standard fitting for global Zone 1/Zone 2 hazardous engineering projects.
2.1 Core Certification & Safety Grade
Safety Parameters: The EX-3 model carries official ATEX and IECEx certification with Exd IIC Gb rating, applicable for high-risk explosive media such as hydrogen and acetylene. It adopts UL94-V0 flame retardant standard and is equipped with CE, RoHS, REACH and UL qualifications, meeting all international hazardous area safety acceptance criteria.
2.2 Material & Environmental Resistance Performance
Material Configuration: Two industrial-grade material options are available. Nickel-plated brass is suitable for general chemical and indoor hazardous workshops. SS304/SS316L stainless steel adapts to offshore platforms, coastal factories and strong corrosive environments. Precision plating and passivation treatment achieves excellent anti-rust and anti-corrosion capability.
Protection Performance: Equipped with silicone and neoprene composite sealing rings, Hoonsun EX-3 reaches IP68 10-bar deep waterproof and dustproof level, effectively isolating external moisture, dust and explosive gas. The built-in reinforced strain relief structure prevents cable loosening and damage caused by tension and bending.
2.3 Specification & Installation Adaptability
Installation Advantages: This model supports a cable diameter range of 3mm–44mm. Standard M/PG threads and customized NPT/G threads are optional. The modular split structure realizes tool-free quick installation and maintenance, with high compatibility for explosion-proof junction boxes, distribution cabinets and instrumentation equipment.
2.4 Product Advantages & Application Scenarios
Core Advantages: Hoonsun EX-3 integrates flameproof, waterproof, dustproof, anti-corrosion and anti-pull functions. It fixes common defects of traditional glands such as poor sealing and easy rusting, featuring stable operation and low later maintenance cost with high cost performance.
Applicable Industries: Widely used in oil & gas exploitation, petrochemical processing, pharmaceutical manufacturing, coal mining, new energy chemical industry and marine engineering. It works stably in both Zone 1 continuous and Zone 2 intermittent explosive hazardous environments.
