Technical Anatomy: Cable Gland Parts Name & Engineering PDF Breakdown
A rigorous engineering breakdown of mechanical components inside an industrial and hazardous-area cable entry system according to BS 6121, IEC 62444, and UL 514B guidelines.
In electromechanical engineering, electrical control instrumentation, and petrochemical containment infrastructure, a cable gland serves as a critical mechanical entry and sealing device. Understanding the definitive nomenclature behind each internal component is crucial for design engineers drafting mechanical layout drawings, MEP contractors requesting technical submittals, and procurement directors auditing cable gland parts name PDF schematics.
1. Locknut (Jam Nut)
Fabricated in nickel-plated brass (HPb59-1), SUS304, SUS316L, or Polyamide 66. It anchors the gland body through unthreaded clearance knockouts onto panel walls, distributing uniform mechanical torque to prevent loosening under heavy dynamic vibrations.
2. Sealing Washer / O-Ring
Positioned on the entry thread interface to form an impermeable liquid barrier between the gland shoulder and enclosure face. Manufactured from NBR, high-temp silicone, or fluoroelastomer (FKM) to withstand immersion pressure up to 10 bar (IP68/IP69K).
3. Gland Body (Entry Component)
The central structural housing featuring external entry threads (Metric, NPT, PG, or G/BSPP) and internal conduits. It anchors the sealing components and transmits mechanical tensile loads away from fragile copper conductor terminations.
4. Clamping Claw & Cage
A multi-finger segmented collet generally engineered from modified PA66 with high flexural fatigue resistance. When driven axially by the cap nut, the fingers compress evenly inward to secure heavy radial strain relief without pinching or deforming the cable jacket.
5. Elastomeric Sealing Grommet
The vital sealing heart that envelopes the cable circumference. HOONSUN formulates proprietary vulcanized EPDM, Santoprene, and fluorinated silicone seals engineered to survive extreme thermal shifts (-60°C to +180°C) without taking compression sets.
6. Compression Cap Nut
Featuring hexagonal wrench flats configured to ISO 272 standards for calibrated torque application. As tightened, internal conical bevels smoothly convert torque into axial displacement, clamping down the claw and hermetically displacing the sealing grommet.
7. Armour Cone & Clamping Ring
Found exclusively in armored cable glands (such as BW, CW, E1W, and marine JIS types). Clamps steel wire armour (SWA), steel tape armour (STA), or braided aluminium armours, ensuring electrical continuity for low-resistance earth fault currents.
8. Earth Tag (Grounding Continuity)
A conductive brass or tinned copper ring slipped between the enclosure wall and locknut. Certified to high-fault rating standards, ensuring that transient surges or fault voltages safely discharge into the plant ground path without arc ignitions.
9. Protective Outer PVC/PCP Shroud
A heavy-duty flexible polymeric boot slipping over the completed cable gland assembly. Provides supplementary protection against prolonged coastal salt air, airborne sulfuric acids, heavy petrochemical downpours, and particulate build-up.

Technology Roadmap & Next-Generation Engineering Trends
Where connection technology is heading: intelligent diagnostic cable entries, bio-based engineering polymers, and high-frequency EMI shielding.
Sensory & Smart Diagnostic Glands
As unmanned substations and offshore wind platforms become mainstream, automated condition monitoring is shifting directly to the cable entry interface. Future cable gland architectures will integrate passive RFID thermal monitoring chips and piezoelectric pressure micro-sensors. These sensors will flag loose compression nuts, localized cable overheating, or seal degradation before electrical faults happen.
Halogen-Free & Bio-Circular Polymers
Global environmental mandates—including the European Union's circular economy guidelines—are accelerating the shift towards halogen-free, non-phosphorus flame-retardant thermoplastics. HOONSUN is actively developing bio-based polyamide formulations derived from castor plant chemistry that deliver high UL 94 V-0 flammability ratings without releasing toxic fumes or halogenated hydrogen acids during a fire.
Subsea Dynamic Immersion Technology
With floating offshore wind platforms moving into deeper waters, hydrostatic pressures exceed conventional onshore testing parameters. Next-generation marine cable gland designs incorporate multi-stage stepped elastomeric seals with balanced inner relief chambers, ensuring that hydrostatic water pressure actually increases the radial compression seal around the cable rather than forcing water past the seal lip.

Comprehensive Engineering & Procurement FAQ
Clear, definitive answers addressing technical selection, documentation submittals, and ordering procedures.
How can I download the official "Cable Gland Parts Name PDF" technical drawing sheet?
You can request the complete technical catalog and dimensional PDF drawing sheets directly by submitting an RFQ or contacting our engineering sales department via email at [email protected]. Our engineering submittal packets provide 2D exploded mechanical views, complete component parts nomenclatures, thread pitches, wrench hex dimensions, and permissible cable diameter ranges for every part number.
What is the functional difference between Metric, PG, NPT, and G (BSPP) threads?
Metric (M) Threads conform to ISO 68-1 with a 60° thread angle and standardized millimetric pitch (e.g., M20x1.5), representing the global standard across Europe, Asia, and modern automation systems. PG (Panzergewinde) Threads follow German DIN 40430 standards with an 80° angle and shallower depth, widely found on legacy European industrial control equipment. NPT (National Pipe Taper) features a 1:16 tapered thread profile per ANSI B1.20.1, creating a mechanical interference seal along the thread flank common in North American applications. G Threads (BSPP) are parallel pipe threads configured to ISO 228-1 with a 55° Whitworth thread angle, requiring an entry washer or O-ring to form a watertight seal.
When should engineers specify stainless steel 316L cable glands over nickel-plated brass?
While nickel-plated brass (HPb59-1 or CW614N) provides outstanding mechanical durability and moderate corrosion resistance for standard industrial automation, motors, and indoor switchgear, austenitic stainless steel grade AISI 316L (containing 2-3% molybdenum) is essential in environments exposed to chlorides, saltwater spray, chemical washdowns, or acidic atmospheres. These include marine shipbuilding, offshore oil platforms, seaside solar parks, pharmaceutical washdown enclosures, and food processing lines.
How does an armored cable gland differ from an unarmored cable gland?
An unarmored cable gland uses a single elastomeric seal to compress directly around the smooth outer jacket of the cable for ingress protection and strain relief. In contrast, an armored cable gland (such as BW, CW, or E1W series) incorporates internal mechanical cones, clamping rings, or armor lock sleeves. These clamp down on the steel wire armor (SWA), steel tape armor (STA), or braided wire layer, providing high pull-out retention and maintaining electrical earth fault bonding continuity.
What does an IP68 rating actually guarantee under international testing criteria?
Per IEC 60529, the first numeral '6' denotes that the cable gland is totally dust-tight against particulate penetration. The second numeral '8' signifies protection against continuous immersion in water under conditions specified by the manufacturer. HOONSUN certifies its IP68 assemblies for continuous immersion at 5 to 10 bar water pressure (equivalent to 50–100 meters of submersion) when the cable outer diameter falls within our stated clamping range and the cap nut is torqued to factory specifications.
Can HOONSUN produce customized thread lengths, entry sizes, or private-label packaging?
Yes. As an authentic manufacturer founded in 2006, HOONSUN provides comprehensive OEM and ODM engineering services. We frequently machine extended entry thread lengths to pass through thick enclosure walls or concrete cast boxes, mill custom multiple-hole inner grommets for specialized wire harnesses, apply custom galvanic coatings, and deliver customized barcoded retail or wholesale packaging.
