Our featured multi-hole cable glands are purpose-built for armored cable management β delivering superior sealing, mechanical strength, and certified protection for critical infrastructure installations.
A multiple hole cable gland β also known as a multi-entry cable gland β is a precision-engineered sealing device designed to route two or more armored or unarmored cables through a single panel knockout or enclosure wall. Unlike traditional single-entry glands, multi-hole variants dramatically reduce the number of required penetrations, simplify cable routing architecture, and maintain certified IP protection ratings across all entries simultaneously.
When managing armored cables in high-density environments β from offshore platforms to industrial automation panels β multiple hole cable glands reduce installation time by up to 60%, minimize enclosure footprint, and ensure every cable entry achieves IP68-rated waterproof sealing and UL-listed mechanical protection simultaneously.
Every multiple hole cable gland from Hoonsun is engineered to exceed international standards, combining advanced materials science with precision manufacturing for armored cable management excellence.
Certified for continuous submersion up to 10 meters. Each cable entry port maintains an independent hermetic seal, preventing moisture ingress even under extreme pressure differentials in buried or submerged installations.
Full UL listing and ATEX explosion-proof certification ensures compliance for hazardous area installations, including Zone 1 and Zone 2 classified environments in oil & gas, chemical processing, and mining sectors.
Integrated 360Β° armor clamping mechanism provides superior mechanical grip on SWA (steel wire armored) and STA (steel tape armored) cables, delivering EMC shielding continuity and outstanding pull-out resistance.
Engineered for operation from -40Β°C to +120Β°C, making these glands suitable for arctic pipeline installations, high-temperature industrial furnace control panels, and everything in between.
Available in nickel-plated brass, 316L stainless steel, and glass-fiber reinforced nylon β each material optimized for specific environments including marine, corrosive chemical, and lightweight structural applications.
Available in 2-hole, 3-hole, 4-hole, 6-hole, and custom configurations with mixed cable diameter entries, enabling engineers to design optimized cable management layouts for any enclosure geometry.
The global cable gland market is undergoing a significant transformation driven by the rapid expansion of industrial automation, renewable energy infrastructure, and smart manufacturing. Understanding these trends is essential for procurement engineers and project managers selecting armored cable management solutions.
The global solar PV and offshore wind sectors are projected to install over 500 GW of new capacity annually through 2030. Each utility-scale installation requires thousands of armored cable penetrations through weatherproof enclosures, junction boxes, and inverter cabinets β making multi-hole cable glands a critical BOM component. IP68-rated multi-entry glands reduce installation labor costs by consolidating multiple cable entries into a single sealed unit, directly improving project economics for EPC contractors.
As manufacturing facilities adopt smart automation, sensor networks, and IIoT (Industrial Internet of Things) infrastructure, the density of cables entering control panels has increased dramatically. Modern PLC cabinets, motor control centers, and distributed I/O enclosures now require 8β20+ cable entries per enclosure. Multiple hole cable glands address this challenge elegantly, maintaining enclosure integrity while accommodating high cable density β a requirement that conventional single-entry glands simply cannot meet efficiently.
Offshore oil platforms, LNG terminals, and naval vessels represent some of the most demanding environments for cable management. The global offshore construction market is expanding significantly, with new FPSO vessels, subsea processing systems, and offshore wind substations requiring explosion-proof, IP68-rated armored cable glands certified to IECEx, ATEX, and DNV marine standards. Multi-hole glands with integrated armor clamping are becoming the specification standard in marine engineering contracts worldwide.
High-speed rail networks and electric vehicle charging infrastructure are expanding globally, both requiring robust, vibration-resistant cable management solutions. Armored cables in traction control systems, trackside signaling equipment, and DC fast charger installations must be sealed against moisture, dust, and mechanical shock. Multi-hole cable glands with anti-vibration features and IP68 ratings are increasingly specified in railway engineering standards (EN 50264, IEC 60332) and EV infrastructure projects.
The industry is shifting toward REACH-compliant, RoHS-certified materials that eliminate hazardous substances while maintaining performance. Advanced polymer compounds, stainless steel alloys, and surface treatment technologies are enabling cable glands to withstand increasingly aggressive chemical environments while meeting tightening environmental regulations in the EU, North America, and Asia-Pacific markets. Breathable cable glands with pressure equalization membranes represent a notable innovation, preventing condensation-induced failures in sealed outdoor enclosures.
Procurement specifications are becoming increasingly rigorous, with project owners demanding dual or triple certification (e.g., IP68 + UL + ATEX) on single components. This trend is consolidating the market around manufacturers with comprehensive certification capabilities. The ability to supply multi-hole cable glands that simultaneously meet IEC, UL, CE, and marine classification society standards is becoming a key competitive differentiator in global infrastructure tenders.
Multiple hole cable glands for armored cable management are deployed across a remarkably diverse range of industries. Here we examine the most critical application environments and the specific engineering requirements they impose.
High-density PLC and MCC enclosures require multiple SWA cable entries through a single gland plate. Multi-hole glands with individual sealing inserts accommodate mixed cable diameters (4mmβ25mm) in a single installation, maintaining IP66/IP68 enclosure ratings while providing EMC shielding through continuous armor contact.
Photovoltaic string combiner boxes and wind turbine nacelle junction boxes face UV radiation, temperature cycling, and moisture ingress. IP68 multi-hole cable glands with UV-stabilized materials and EPDM sealing elements ensure 25+ year service life, matching the operational lifespan of renewable energy assets.
ATEX Zone 1/2 classified areas in refineries, offshore platforms, and LNG facilities demand Ex-rated cable glands that maintain flameproof integrity. Multi-hole Ex glands eliminate the need for multiple individual Ex penetrations, reducing installation cost and the number of potential leak points in hazardous area cable management systems.
Shipboard cable penetrations through watertight bulkheads must maintain the vessel's structural integrity. Multi-hole marine cable glands certified to DNV, Lloyd's Register, and IEC 60092 standards provide tested watertight sealing for armored cables in engine rooms, accommodation modules, and topside electrical systems.
Data center cable management requires dust-tight, organized penetrations through fire-rated walls and floor slabs. Multi-hole glands with intumescent sealing options provide both cable management efficiency and passive fire protection, meeting FM Global and NFPA 75 requirements for critical facility infrastructure.
Trackside signaling cabinets and traction power substations require cable management solutions that withstand constant mechanical vibration, temperature extremes, and occasional flooding. Anti-vibration multi-hole cable glands with stainless steel construction and IP68 ratings are specified in metro, high-speed rail, and light rail infrastructure projects globally.
