For more than 40 years, Three-D Agencies has been a reputable cable accessories distributor through Southern Africa. The company supplies products relating to cable glands, lugs, terminals, and electrical protection products into the mining, industrial, agricultural, marine, solar, and wholesale markets. When it comes to these types of components, such as cable glands and lugs, the quality and material selection is important. In the extreme environments that exist in South Africa, HEX brass cable glands and lugs are robust and reliable choices for keeping operations safe and efficient.

The Importance of Cable Glands

Cable glands may seem like small components, but their presence can determine a successful installation. The purpose of a cable gland is to secure a cable, provide strain relief, and protect the connection from harmful environmental ingress, such as dust, water, or chemicals, when transitioning from a cable to a piece of equipment. 
If a gland fails, the entire system is compromised. This could lead to electrical faults, unplanned downtime, or, worse, safety risks. Such matters are severe in areas such as mining, renewable energy, or heavy industry, given the risks involved, so material quality is important.

Why Brass?

Brass as an alloy of copper and zinc has long been well known for its durability and performance. Unlike plastics or cheaper metals, brass offers resistance to many of the environmental challenges common in South Africa.

  • Brass is highly resistant to corrosion. Coastal areas like KwaZulu-Natal and Western Cape are subjected to high humidity and salty air, and if you use a lesser material, it will deteriorate very quickly. HEX has developed a brass cable glands and lugs that will last in coastal conditions, especially if they have been nickel plated for an even greater layer of protection.
  • Brass is mechanically strong. In mining or industrial applications, glands are subjected to vibration, abrasion, and rough handling.
  • Brass has excellent thermal stability. In South Africa, it is not uncommon for equipment to be exposed to very high temperatures during the day and cooler temperatures at night. In solar farms, or industrial plants, equipment can also expose components to heat from the equipment itself. Brass does not warp, degrade, or lose grip due to these temperature variations.

New chemical and industrial sites present challenges for cables as well, with exposure to acids, alkalis or cleaning agents HEX has designed a range of solid brass products, including brass lugs, for added protection. When it comes to agriculture, irrigation, fertilisers, and salt air exposure can all reduce the working life of cables. Brass offers the durability needed to get maintenance mileage from cables under extreme dust or wet conditions.

Ease of Installation and Maintenance  

HEX brass cable glands are easy to use. Their threads, seals, and fittings are made to maintain high tolerances. This allows installers to get a secure and correct fit without much effort. When a brass gland is installed properly, it lasts a long time and needs very little maintenance.

For businesses, this leads to significant cost savings. Less downtime, fewer replacements, and longer operational life all contribute to a lower total cost of ownership. In industries where every hour of downtime can cost thousands of rands, investing in durable parts like HEX brass glands and lugs is both economically and technically sensible.

Applications Across South Africa

HEX brass glands and lugs have shown their value in various sectors in South Africa. In mining, they endure vibration, dust, and chemicals, keeping essential machinery running safely. In solar farms, they manage drastic temperature changes and constant UV exposure. Along the coast, they withstand the harmful effects of salt spray, protecting marine installations, ports, and desalination plants. In chemical and food processing plants, they maintain secure seals, despite steam, cleaning agents, and other tough conditions.
