Explore our UL-certified and IP68-certified explosion-proof, metal, and nylon entry systems designed for extreme industrial stresses.
An in-depth structural review of high-capacity wire entry systems designed for ultra-heavy infrastructure, mining, maritime transmission, and industrial utilities.
In heavy-duty power distribution and high-voltage transmission networks, terminal terminations require absolute sealing integrity and mechanical strain relief. The 150 mm cable gland size denotes a category of massive cable entry systems engineered to handle cables with outer diameters approaching or matching 150 mm, or Metric M150 threaded configurations designed for thick multicore heavy-armored lines. When routing high-voltage power cables in hazardous oil fields, offshore wind stations, or metro rail corridors, choosing the correct gland material, pitch size, and clamping mechanism dictates the longevity of the electrical installation.
As a leading Chinese designer and precision manufacturer, Zhejiang Hongxiang Connector Co., Ltd. builds heavy-duty connectors targeting these extreme applications. Deploying components at this scale requires a comprehensive grasp of dynamic loads, environmental sealing classifications, and explosive atmosphere safety. To ensure safety, our product line integrates internal armor clamping rings, dual-compression seals (inner and outer sheaths), and massive continuous grounding pathways (EMC compatibility) to handle faults without electrical breakdown.
Capable of supporting high torque installations up to 240 Nm, ensuring large-diameter armored cables remain securely anchored against severe tension and thermal expansion-contraction cycles.
Utilizing high-performance EPDM and Silicon rubber inserts to deliver sealing integrity from -60°C to 150°C, maintaining elasticity under continuous chemical and ozone exposure.
Ex d IIC Gb and Ex e IIC Gb compliant engineering. Specifically fabricated to contain internal ignition risks in explosive chemical vapors, oil sands, and methane-heavy environments.
A common point of confusion in structural design is distinguishing the gland entry thread size from the cable clamping capacity. When specifying a 150 mm cable gland, design engineers generally refer to either:
| Gland Reference Size | Entry Thread (D1) | Clamping Range (Min - Max Cable OD) | Thread Length (Min) | Typical Materials | Standard Certifications |
|---|---|---|---|---|---|
| M120 Heavy-Duty | 120 mm | 88.0 mm - 105.0 mm | 20 mm | Nickel-Plated Brass / SS316L | UL, CE, IP68 |
| M150 Ultra-Heavy | 150 mm | 110.0 mm - 135.0 mm | 25 mm | SS316L, Marine Brass | ATEX, IECEx, UL, IP69K |
| Custom 150mm OD Gland | 160 mm / NPT 5" | 132.0 mm - 150.0 mm | 25 mm | Nickel-Plated Brass | ATEX, CE, RoHS, IP68 |
Empirical evidence of Hongxiang's industrial dominance across heavy infrastructure, renewable energy, and automated control systems.
Cable glands are critical for new energy vehicles (NEVs), serving as essential components to manage and protect cables in high-voltage systems, battery packs, motor controllers, charging interfaces, and other core electrical units. Engineered to withstand extreme temperatures, vibration, moisture, and chemical exposure, they ensure reliable sealing, prevent dust/water ingress, and maintain insulation integrity to avoid electrical hazards. By securing and routing power, signal, and communication cables, they enhance the safety, stability, durability, and performance consistency of the vehicle’s electrical system. Compliant with automotive industry standards, high-quality cable glands help NEVs meet strict safety and reliability requirements, making them indispensable for electric cars, hybrid vehicles, and other new energy mobility solutions.
Cable glands are essential for robotics, managing and protecting power, signal, and data cables in industrial robots, cobots, AMRs, and more. Adapted to dynamic movements, harsh industrial environments (dust, coolant, mechanical stress), they prevent tangling, abrasion, and disconnection while ensuring IP68-rated sealing. By safeguarding electrical connections and reducing cable wear, they enhance robotic operational stability, precision, and service life. Compatible with various cable sizes and compliant with IEC/UL standards, they are foundational for reliable robotic systems.
Cable glands are vital for onshore/offshore wind power systems (turbines, substations, tower bases), protecting power/control/signal cables. Engineered to resist salt fog, extreme temps (-52℃ to 90℃), vibration, and UV, they offer IP68 sealing, explosion-proof performance, and EMC shielding. Made of durable EPDM rubber or 316L stainless steel or brass , they prevent cable abrasion/displacement and electrical hazards, ensuring long-term operational stability and safety.
Cable glands are key protective components in rail transit systems, widely used in rolling stock, substations, tunnels, and equipment rooms of metro, high-speed rail, and intercity rail. They secure and protect power, control, and signal cables. Adapted to harsh operating conditions, they feature an IP68 protection rating, resisting moisture, dust, and rodent damage, while withstanding extreme temperatures from -40℃ to 90℃ and continuous vibration. They are offering explosion-proof and sealing performance to prevent cable abrasion, signal interference, and fire spread. Their modular design supports future capacity expansion, extends the service life of cables and equipment, and ensures the long-term safe and stable operation of rail transit systems.
