corrugated conduit

In industrial machinery, electrical control systems, and outdoor harsh environments, managing dual parallel pipelines (power cables and signal conduits) poses unique challenges—securing two lines simultaneously while resisting moisture, corrosion, and vibration. Standard single-port glands require multiple installations, increasing leakage risks and wiring clutter. Bellows double fixed glands address this gap with symmetrical dual-interface design, merging robust protection and space-saving efficiency to become the backbone of reliable dual-pipeline management.
 
1. The Hidden Risks of Dual-Pipeline Mismanagement
Dual-pipeline systems are prone to overlooked failures. In automated factories, loose parallel cables exposed to hydraulic oil suffer 40% higher corrosion rates than secured ones. High-density electrical cabinets with multiple single-port openings see 2x more dust and moisture intrusion, leading to short circuits. Outdoor solar stations often face signal interruptions when unprotected dual conduits are damaged by salt spray. Standard solutions fall short: multiple single glands waste 30%+ cabinet space, and basic seals can’t withstand dual-line pressure, resulting in unplanned downtime costing $150,000+ per incident for manufacturers.

 
2. Core Advantages: What Makes Bellows Double Fixed Glands Stand Out
Engineered for dual-pipeline demands, these glands combine advanced materials and structural innovation to solve industry pain points:
Dual-Channel Rigid Locking: Symmetrical dual-interface design with precise threads provides secure locking for two bellows or a cable-bellow combination. PA66 nylon body delivers >800N compressive strength, resisting vibration and impact to prevent line loosening.
Redundant Protection Options: IP66/IP68 ratings available—IP66 blocks high-pressure water jets and dust, while IP68 withstands 1.5m/72h submersion. PA66’s chemical resistance (pH 3-11) and UV resistance (1000h salt spray test passed) ensure durability in harsh environments.
All-Weather & Safety Assurance: Stable performance from -40°C to 125°C; customizable high-temperature seals extend range to -60°C~200°C. V1 flame-retardant certification stops fire spread along pipelines, and 20kV/mm+ dielectric strength safeguards high-voltage areas.
Space & Efficiency Boost: Coaxial design reduces cabinet openings by 50%, cutting installation nodes and clutter. Straight-through structure saves over 40% wiring space, ideal for compact PLC cabinets.

 
3. Cross-Industry Applications: Where These Glands Excel
Bellows double fixed glands thrive in scenarios requiring dual-line protection and efficiency:
Industrial Machinery: In automated assembly lines, CNC machines, and logistics sorters, they secure power and signal lines against hydraulic oil, metal debris, and high-frequency vibration. IP68 seals prevent fluid intrusion, reducing cable failure rates by 65% and keeping production uninterrupted.
Electrical Control Cabinets: They manage dual-line entry with single-point IP68 sealing, blocking condensation and conductive dust. The space-saving design improves heat dissipation efficiency by 25%, while flame retardancy limits arc-fault risks—perfect for high-density inverter and PLC cabinets.
Outdoor & Harsh Environments: For solar combiner boxes and coastal wind turbine nacelles, their UV-resistant, salt-spray-proof structure protects dual conduits. IP68 rating withstands storms and sandstorms, ensuring stable power and communication signal transmission.
Emerging High-Value Sectors: New energy charging stations use them for 250A dual-gun cables, with anti-EMI and cold-resistant seals (-60°C) for northern regions. Rail transit undercarriage boxes rely on their anti-vibration design (IEC 61373 certified) to secure brake and signal lines. Semiconductor cleanrooms use dust-free coated versions (ISO Class 5) to block particulates.
 
4. Customization: Tailored to Specialized Needs
Dual-pipeline requirements vary, and flexible customization expands these glands’ applicability:
Environmental Upgrades: High-temperature rubber seals (-60°C~200°C) for foundries or cold-region equipment; explosion-proof certifications for hazardous areas.
Dimensional & Interface Flexibility: Non-standard thread sizes (PG/M types available) and custom colors for safety coding; special angles for tight installation spaces.
Industry-Specific Tweaks: Anti-static modifications for electronics manufacturing; chemical-resistant coatings for extreme industrial solvents.
 
5. The ROI of Professional Dual-Pipeline Protection
These glands are more than components—they’re efficiency investments. A mid-sized solar farm reported:
55% reduction in dual-line maintenance costs after adoption
70% fewer unplanned outages due to pipeline failures
40% space savings in control cabinet wiring
 
For industries where dual-pipeline reliability directly impacts productivity, the value of streamlined, protected connections is undeniable.
 
 

Today (August 26, 2025), the 16th Shenzhen International Connectors, Cables, Cable Harnesses & Processing Machinery Exhibition (ICH Shenzhen 2025) officially opened at the Shenzhen International Convention and Exhibition Center (Bao'an New Hall). As a "one-stop" ecosystem event for the connector industry, this year's exhibition, themed "Smart Industry, Connecting the Future," attracted over 700 global exhibitors, covering core sectors such as new energy, automotive manufacturing, and industrial automation. Among them, Wenzhou Chuangda Connector Co., Ltd. (hereinafter referred to as "Chuangda"), a small but sophisticated company deeply engaged in the connector and cable accessories field, showcased its core products at the exhibition, injecting fresh vitality into the industry.

I. Exhibition: A 40,000-square-meter flagship platform connecting global industry opportunities
