Jamnagar: India's Brass Capital and the Foundation of Cable Gland Manufacturing
Jamnagar, situated on the northwestern coast of Gujarat, has carried the title of India’s brass capital for well over half a century. The city and its surrounding industrial zones particularly Udhyognagar and Shanker Tekri are home to thousands of brass machining units, ranging from small precision workshops to large integrated manufacturing facilities. This deep concentration of brass manufacturing expertise is the single most important factor behind Jamnagar’s dominance in cable gland production globally.
Brass is the material of choice for industrial cable glands because of its exceptional properties: excellent corrosion resistance, superior machinability, good tensile strength, non-sparking characteristics in hazardous environments, and inherent compatibility with a wide range of chemical environments. Jamnagar’s manufacturers have refined their brass machining processes over generations, achieving the dimensional tolerances and surface finishes that meet international standards including the precision required for ATEX-certified explosion-proof assemblies where thread engagement and sealing performance are safety-critical.
The Raw Material Advantage
Gujarat’s industrial infrastructure supports a continuous, cost-efficient supply of high-grade brass billets and rods to Jamnagar’s manufacturing base. The proximity of major ports including Kandla and Mundra enables both efficient import of copper and zinc (the primary constituents of brass) and rapid export of finished products to international markets. This logistics advantage translates directly into shorter lead times and competitive pricing for buyers sourcing cable glands from Jamnagar suppliers, particularly on large EPC projects where procurement cost and schedule both matter.
Skilled Workforce and Engineering Expertise
The depth of precision machining knowledge in Jamnagar is generational. Families have worked in brass machining for decades, and this knowledge base is continuously replenished through local technical institutes and apprenticeship programmes. For cable gland manufacturers like Exgrip, this means access to machinists, quality control technicians, and production engineers who understand the specific tolerances, thread forms, and sealing requirements that industrial cable gland standards demand including the exacting manufacturing and documentation requirements of IECEx and ATEX certification bodies.

Cable Gland Size Chart: Selecting the Right Gland for Your Application
Correct cable gland size selection is critical for maintaining IP-rated ingress protection, cable retention performance, and the mechanical integrity of the cable entry point. The cable gland size must match the outer diameter of the cable being terminated an undersized gland will not seal, while an oversized gland will fail to grip the cable sheath effectively.

ATEX Certification, IECEx, and PESO: What Certified Means for Indian Buyers
The word certified carries significant technical and legal weight when specifying cable glands for hazardous area installations. In India’s oil refineries, petrochemical complexes, offshore platforms, and chemical processing plants, uncertified cable glands are not merely non-compliant they represent a direct safety liability and an insurance and regulatory exposure. Jamnagar-based manufacturers that have secured internationally recognised hazardous area certifications represent the top tier of India’s industrial cable gland supply chain.
ATEX Full Form and What It Covers
ATEX is derived from the French phrase ATmospheres EXplosibles literally, explosive atmospheres. ATEX certification is the European Union’s framework (Directive 2014/34/EU) for equipment intended for use in potentially explosive atmospheres and is recognised globally as a benchmark for hazardous area equipment safety. Cable glands certified under ATEX are independently tested and verified to maintain their flameproof, increased safety, or dust ignition-proof protection in Zone 1 and Zone 2 classified hazardous areas where flammable gases, vapours, or dusts may be present.
Exgrip holds ATEX certification across multiple protection concepts: Ex db (flameproof enclosure), Ex eb (increased safety), and Ex ta (dust ignition protection). This breadth of certification means a single Jamnagar-based supplier can address the complete range of hazardous area cable entry requirements across different enclosure types and zone classifications on a single industrial project.
IECEx Certification: The Global Standard
IECEx is the International Electrotechnical Commission’s certification scheme for equipment used in explosive atmospheres, accepted across more than 50 countries including Australia, the Middle East, Southeast Asia, and Africa. While ATEX applies specifically within the European Economic Area, IECEx carries broader international recognition. For Indian manufacturers like Exgrip, holding both ATEX certification and IECEx certification enables supply to both domestic and export markets from a single audited product range a significant commercial and compliance advantage when bidding on international EPC contracts.
PESO Approval for Indian Oil and Gas Projects
In India, the Petroleum and Explosives Safety Organisation (PESO) approval is a mandatory compliance requirement for electrical equipment including cable glands installed in petroleum storage, handling, and processing facilities. Any cable gland specified for Indian oil refineries, LPG facilities, or fuel handling terminals must carry valid PESO approval alongside its international hazardous area certifications. Exgrip’s cable gland range is PESO approved, making its products fully compliant for the entire spectrum of Indian industrial, petrochemical, and oil and gas installations.

FAQs
Why is Jamnagar known as the brass capital of India?
What is a double compression cable gland and when is it used?
A double compression cable gland is designed specifically for armoured cables most commonly steel wire armoured (SWA) or aluminium wire armoured (AWA) cables. It features two compression points: one that mechanically clamps the cable armour for retention and earthing continuity, and one that seals the cable outer sheath for IP-rated ingress protection. Double compression glands are the standard specification for outdoor installations, direct buried cables, and hazardous area cable entries in Zone 1 and Zone 2 classified environments. Exgrip’s double compression range includes the E1FW, DCA, and DCU models.
What does ATEX full form mean and why does it matter?
ATEX stands for ATmosphères EXplosibles French for explosive atmospheres. It refers to European Union Directive 2014/34/EU, which sets mandatory safety standards for equipment used in potentially explosive atmospheres. ATEX-certified cable glands are independently tested and verified to prevent ignition of surrounding flammable gases, vapours, or combustible dusts. For cable entry into explosion-proof enclosures on oil platforms, refineries, or chemical plants, ATEX certification is a non-negotiable specification requirement. Exgrip holds ATEX certification under the Ex db, Ex eb, and Ex ta protection concepts.
What is the difference between ATEX certification and IECEx certification?
ATEX certification applies specifically within the European Economic Area and is governed by EU directives. IECEx is the International Electrotechnical Commission’s global certification scheme, accepted in over 50 countries including the Middle East, Australia, Southeast Asia, and Africa. While the underlying technical requirements are closely aligned, IECEx carries broader international recognition outside Europe. Exgrip holds both ATEX and IECEx certifications, making its cable glands compliant for both European and international export projects from a single audited product range.
Can Jamnagar cable gland manufacturers supply certified products for export projects?
Yes. Jamnagar-based manufacturers with ATEX and IECEx certification are established suppliers to international EPC projects across the Middle East, Africa, Southeast Asia, and Europe. Exgrip’s proximity to Kandla and Mundra export ports, combined with its internationally recognised certifications and export documentation capabilities, enables efficient supply to project sites outside India with full certification traceability including material test certificates, conformity declarations, and ATEX/IECEx certificate copies.
