Wiping Gland | Heavy Duty Brass

A wiping gland, in the context of electrical engineering, is a type of cable gland designed to provide a secure and sealed entry point for cables into enclosures or equipment, particularly for high-voltage or lead-sheathed cables. Also known as brass wiping glands or earth glands, they are primarily used to mechanically earth the lead sheaths of Paper-Insulated Lead-Covered (PILC) cables and ensure environmental sealing. Here’s a concise overview based on available information:

Key Features of Wiping Glands:

• Material: Typically made from high-quality brass (e.g., BS 2874), sometimes nickel-plated or with a natural finish, for durability and corrosion resistance. Other materials like bronze, aluminum, or stainless steel may also be used.
• Functionality:
  • Sealing: Provides a watertight and weatherproof seal (e.g., IP66, IP67, or IP68 ratings) using components like neoprene gaskets or O-rings to protect against dust, moisture, and contaminants.
  • Self-Wiping Action: Some designs include wiping elements (e.g., brushes) that clean the cable surface during insertion or withdrawal, making them suitable for environments where cleanliness is critical, such as food processing or pharmaceuticals.
  • Earthing: Designed to mechanically earth the lead sheaths of cables, ensuring electrical safety, especially in transformer applications.
  • Strain Relief: Offers mechanical support to prevent cable bending or tension at the entry point.
• Applications:
  • Used with single-wire armored (SWA), plastic, or rubber-sheathed cables, particularly in dry indoor conditions or outdoor harsh environments.
  • Common in electrical transformers, switchgear, control panels, and industries like automotive, telecommunications, and engineering.
  • Facilitates termination of high-voltage power cables.
• Standards: Often comply with standards like BS 6121: Part-1:2005, EN 50262:1999, or IEC 62444:2010.
• Customization: Available in various sizes (e.g., for cables from 12mm to 51mm) and can be manufactured to customer specifications, including custom threads (e.g., BSW, NPT) and finishes (e.g., nickel, tin, or chrome plating).
• Components: May include brass cones, bolt packs, heat-shrink sleeves, and jubilee clips for armor clamping.

Note:

If you meant a different context for “wiping gland” (e.g., a medical or biological term like anal glands in pets, as mentioned in some sources, or sweat glands), please clarify, and I can provide details specific to that field. For electrical wiping glands, the above information covers their primary use and characteristics.
