Featured Industrial Armoured & Heavy-Duty Cable Termination Units
Direct factory precision components compliant with UL, CE, and IP68 standards, engineered by Zhejiang Hongxiang Connector (HOONSUN) for critical mechanical retention, grounding continuity, and environmental sealing.
Macro-Industry Engineering Solutions: Overcoming Heavy Electrification Bottlenecks
Armoured cable entries serve as the fundamental barrier against structural failure, fire containment breakdown, and hazardous gas transmission in high-vibration and extreme industrial environments.
Fault Current & Earth Continuity
In systems carrying Steel Wire Armour (SWA) or Aluminium Wire Armour (AWA), the gland's mechanical clamping cone must support short-circuit fault paths exceeding 10kA for 1 second. HOONSUN's patented internal clamping geometry prevents localized thermal runaway, protecting sensitive internal electronics from grounding anomalies and static surges.
Hydrostatic Sealing & Deluge Protection
Offshore substations, tidal turbines, and oil extraction modules endure salt-saturated vapor combined with cyclical washing deluges. Our specialized dual-elastomer compression matrices achieve steady IP68 ratings at 50 meters hydrostatic depth (5 bar) for continuous immersion, fully tested against DTS 01:91 deluge criteria without grease sealing aids.
Cold Flow & Cable Creep Mitigation
Polymeric cable beddings under continuous mechanical compression undergo irreversible viscoelastic deformation (cold flow), inducing loss of ingress integrity. Our precision engineered displacement seals apply radial hydrostatic pressure rather than destructive longitudinal axial loads, preserving inner core bedding geometry over 30-year operational cycles.
Global Commercial & Industrial Status Quo: Supply Chain De-Risking & Standardization
Engineering procurement teams face unprecedented challenges: volatile raw copper and brass spot rates, regional protectionism, and fragmented international electrical safety standards.
01. The Shift Toward Integrated Direct Manufacturing
Traditional European and North American brand labels have increasingly outsourced upstream casting, machining, and plating while retaining substantial markup margins. Zhejiang Hongxiang Connector (HOONSUN) breaks this legacy dependency by operating end-to-end CNC processing, robotic electro-nickel plating, in-house vulcanization, and continuous dimensional coordinate measurement (CMM) directly in Liushi, Yueqing. Global EPCs obtain primary OEM factory pricing without compromising on metallurgical provenance or batch repeatability.
02. Harmonization of Disparate Regional Codes
Multinational modular skid builders frequently manage disparate projects under Metric (EN/IEC), NPT (NEC/CEC), and PG/BSPP standards concurrently. HOONSUN manufactures cable glands featuring custom thread pitches and engagement depths that satisfy both IEC 60079 flamepath tolerances and North American UL 514B pull-out thresholds. This dual compatibility eliminates enclosure adapter clutter, reduces inventory fragmentation by 45%, and prevents galvanic corrosion triggered by mismatched metal couplings.

Engineering Q&A: Armoured Cable Gland Specification & Auditing
High-gain technical insights for consulting engineers, electrical design leads, and international procurement specialists.
CW Glands: Designed specifically for Steel Wire Armoured (SWA) cables. They feature a single outer elastomeric displacement seal that clamps onto the cable's external sheath, while an internal cone and ring clamp the steel wire armour to guarantee electrical earth continuity.
CX Glands: Optimized for braided, steel tape (STA), or pliable wire armour. They incorporate a specialized reversible clamping ring that accommodates varying tape thicknesses without deforming the internal bedding.
E1W Glands: Heavy-duty double-seal glands. They incorporate an inner seal that compresses directly against the cable inner bedding before the armour clamp, alongside a secondary outer seal that grips the exterior jacket. This dual sealing mechanism provides an explosion-proof flamepath barrier (Ex d) and protects the armour wires from atmospheric moisture and corrosion.
When single-core alternating current (AC) cables operate inside ferromagnetic steel wire armour (SWA), the fluctuating magnetic field induces eddy currents and magnetic hysteresis loops inside the steel wires. This generates rapid, localized heating that can exceed the cable insulation limits (typically 90°C for XLPE), causing insulation degradation and fire hazards. Non-magnetic Aluminium Wire Armour (AWA) breaks this inductive heating loop. Glands applied to single-core cables must feature non-magnetic brass or aluminium clamping components to maintain electrical isolation and prevent thermal failure.
ISO Metric threads utilize a parallel 60° thread angle governed by 6g tolerance classes on external gland threads and 6H on locknuts. NPT threads utilize a 1°47' (3/4 inch per foot) tapered form where sealing is achieved through thread flank interference. At HOONSUN's Yueqing plant, all CNC machines run specialized multi-axis toolpaths with in-line laser measuring and optical comparators. Thread profiles undergo systematic go/no-go ring plug gauge audits on every production lot. This guarantees complete engagement depth without thread galling, cross-threading, or loose tolerances that compromise explosion-proof flamepaths.
The DTS 01:91 test is an aggressive marine industry standard developed to verify that cable glands prevent sea-water intrusion during emergency deluge conditions. Testing requires mounted gland assemblies to be subjected to high-pressure sea-water spray containing wetting agents at a rate of 10 liters/min/m² for a minimum of 3 hours, combined with thermal cycling between ambient and maximum operating limits. HOONSUN's E1W and marine glands incorporate a secondary fluorosilicone radial seal that passes the DTS 01:91 chamber test with zero internal fluid ingress, ensuring subsea and topside continuity without auxiliary greasing.
Under IEC 60079-14 and NEC 501.15, standard elastomeric cable glands are prohibited and barrier glands (such as HOONSUN's compound filled series) become mandatory when all three of the following conditions exist: (1) The installation is located in a Zone 1 / Class I, Division 1 hazardous classification; (2) The connected enclosure is certified Flameproof Ex d containing internal sparking or arcing contacts; and (3) The cable volume exceeds 2 liters or the cable inner bedding does not meet compact extruded concentric gas-migration criteria. The two-part epoxy or silicone resin compound forms a flameproof plug that prevents gas or flame transmission through the cable interstices.
