Proper grounding and bonding with metal cable glands requires establishing continuous electrical paths through threaded connections, using conductive sealing washers, applying proper torque specifications, and maintaining metal-to-metal contact between the gland body and enclosure to ensure effective fault current flow and EMI protection.

Cable glands for renewable energy applications require specialized designs with UV-resistant materials, enhanced sealing capabilities, wide temperature ranges, and long-term durability to withstand 25+ years of outdoor exposure in solar farms and wind installations while maintaining IP65/IP68 protection and electrical integrity.

Breathing and drainage glands prevent condensation by allowing controlled air exchange through breathable membranes while maintaining IP protection, enabling pressure equalization and moisture vapor escape while blocking liquid water ingress, thus eliminating internal condensation buildup that causes electrical failures and equipment corrosion in sealed enclosures.

A2 type brass cable glands feature a robust multi-component construction including a brass body with metric threads, compression sealing system, strain relief mechanism, and integrated earthing continuity, designed specifically for armored cable termination with IP68 environmental protection and mechanical durability for industrial applications requiring long-term reliability.

The key difference in cable gland installation is that threaded entries require direct threading and torque application, while non-threaded entries need additional mounting hardware like locknuts, washers, or flanges to secure the gland properly.

The key to selecting the right cable gland for unarmoured cables lies in matching three critical factors: cable diameter compatibility, environmental protection requirements, and material suitability for your specific application.
