When it comes to building reliable, safe, and efficient electrical systems, one element often gets overlooked, cable accessories. While cables carry the current, it’s the accessories that connect, protect, organise, and support them. At the forefront of supplying these critical components is Three-D Agencies, a trusted name in Southern Africa’s electrical and industrial landscape since 1977.
Three-D Agencies isn’t just a distributor, it’s a partner in progress, helping industries and installers complete their systems with precision-engineered cable accessories that stand up to the toughest demands.
The Hidden Heroes: Why Cable Accessories Matter
Cable accessories serve as the foundation of every successful wiring system. They ensure:
- Secure connections through lugs, terminals, and glands.
- Organised installations using cable ties, trunking, and clips.
- Protection from damage using heat-shrink tubing, spiral wrap, and grommets.
- Longevity and safety by shielding cables from chemicals, heat, and abrasion.
- Efficiency and clarity with markers, labels, and colour-coded sleeves.
Without these, even the best cables are vulnerable to failure, misidentification, or safety risks. That’s why professionals turn to Three-D Agencies, a supplier known for delivering comprehensive solutions, not just products.
A Full Range for Every Application
Three-D Agencies offers a wide selection of accessories for diverse environments, from heavy-duty industrial sites to residential installations and renewable energy farms.
A strong, secure connection is essential for system integrity. Three-D supplies high-quality copper, aluminium, and bi-metallic lugs and terminals for various cable sizes and current ratings. These are ideal for switchboards, motor connections, and heavy machinery where reliability can’t be compromised.
2. Cable Glands and Bushings
Sealing off enclosures and entry points is critical to prevent dust, water, and other contaminants from entering. Three-D’s cable glands, available in nylon, brass, and stainless steel, offer IP-rated protection while maintaining flexibility and strain relief.
3. Heat-Shrink Tubing and Sleeving
Used to insulate and protect cable joints, Three-D’s heat-shrink products are available in a variety of materials and shrink ratios. They’re used extensively in automotive, marine, and solar applications to guard against abrasion, weathering, and moisture ingress.
4. Cable Ties, Clips, and Mounts
Managing cabling in a neat and tamper-proof way is essential for both safety and aesthetics. Three-D offers nylon and stainless-steel cable ties, saddle mounts, and cable clips for organised routing that supports fast troubleshooting and long-term performance.
5. Cable Trunking and Conduit
For more complex or large-scale installations, cable trunking and conduit systems provide structured and scalable solutions. These protect against physical damage while keeping cables easily accessible for upgrades or inspections.
6. Cable Markers and Labelling
From power plants to data centres, accurate cable identification saves hours during fault-finding and maintenance. Three-D stocks high-quality markers, label printers, and sleeves that simplify identification even in tight or dimly lit spaces.
7. Tools for Installation
To complement their accessories, Three-D offers crimping tools, tie guns, stripping tools, and testing equipment, ensuring professionals have everything they need for a fast and flawless installation.
