How Many Types of Cable Glanding Are There?
There are numerous varieties of cable glands, each made to satisfy particular needs for covering, sealing, and securing cables. Based on their materials, uses, and compatibility with different cable types, the main types of cable glanding can be divided into different categories. Below is a summary of the primary kinds:
1. By Cable Type Compatibility
Armored Cable Glands
Designed to provide durability and resistance to mechanical stress for wires with an armored protective coating. To fasten the armor and join its electrical and mechanical parts, they include clamping mechanisms.
Unarmored Cable Glands
Used for ordinary cables that aren’t armored. They are more appropriate for low-risk settings but offer crucial sealing and strain relief.
2. By Specific Application
Electromagnetic Compatibility (EMC) Glands
Guard against electromagnetic interference (EMI), which is frequently present in sensitive electrical devices and telecommunications.
Marine Cable Glands
Watertight sealing for maritime and wastewater applications, designed for submerged or moist situations.
Electrical Cable Glands
usually made of metal, with earthing elements to securely reroute electrical currents and avoid electrocution or short circuit damage.
Fire-Stop Cable Glands
During situations, resist fire and stop smoke from spreading while preserving connection integrity. common in sectors that depend on safety and rail.
3. By Standardized Designations (BS 6121)
For certain uses, the British Standard BS 6121 specifies a number of cable gland types, such as:
- Type A: For unarmored plastic or rubber-sheathed cables. Variants include:
- A1: Basic plastic glands for protecting outer jackets.
- A2: Features an IP68 seal for moisture resistance.
- A3/A4: Include electrical bonding for enhanced safety.
- Type B: For single-wire armored cables, made of brass for indoor use.
- Type C: For armored or braided cables with IP68-rated seals, suitable for outdoor use.
- Type D: Similar to Type B but with inner sheath seals, ideal for higher environmental exposure.
- Type E: Designed for armored cables with inner and outer IP68 seals, providing excellent waterproofing for outdoor use.
Suffixes are often added to indicate specific armoring types:
- W: Single wire armor
- T: Pliable wire armor
- X: Wire braid armor
- Y: Aluminum strip armor
- Z: Double steel tape armor
