Material Comparison – Cable Glands
Cable glands are manufactured in different materials to meet diverse industrial requirements. Material choice impacts mechanical strength, chemical resistance, temperature tolerance, and long-term reliability. Understanding these differences is essential for safe and stable electrical installations.
Common Materials and Properties
Material | Typical Use | Temperature Range | Chemical & UV Resistance | Mechanical Strength | Notes |
Nylon (PA66) | General industrial, electrical enclosures | -40°C to 105°C | Good resistance to oils, mild acids, UV | Medium | Lightweight, widely compatible with standard cable ranges |
Brass (Nickel-Plated) | Industrial panels, control boxes | -40°C to 120°C | Excellent corrosion resistance | High | Suitable for outdoor and high-stress applications |
Stainless Steel (316) | Harsh industrial, marine, offshore | -40°C to 150°C | Excellent against corrosion, chemical attack | Very High | Recommended for extreme environments, long service life |
EMC / EMI Metal | Electrical cabinets requiring shielding | -40°C to 120°C | Corrosion-resistant, conductive | High | Provides electromagnetic shielding while maintaining IP rating |
Flame-Retardant Nylon | Cabinets and automation where fire safety required | -40°C to 105°C | Good chemical resistance | Medium | Adds fire retardancy (UL94 V-2 or V-0) without changing standard dimensions |
Decision Tip: Material selection should consider installation environment, exposure to chemicals or UV, mechanical stress, and electrical requirements. Nylon is sufficient for general indoor installations, while brass or stainless steel is recommended for outdoor, high-corrosion, or high-vibration environments.
