Durable connections: All-weather and rubber cables for South African infrastructure
Understanding the need for all-weather and rubber cables
In South Africa, where diverse weather conditions and demanding infrastructure projects are commonality, the importance of durable and reliable cables cannot be overstated. Enter HELUKABEL South Africa, a leading international manufacturer and supplier of cables, wires, and cable accessories. With a commitment to quality and a legacy of innovation, we play a crucial role in ensuring the nation's infrastructure remains resilient, regardless of its environmental challenges.
This comprehensive article delves into all-weather and rubber cables, exploring their significance in South Africa's infrastructure landscape and shedding light on HELUKABEL South Africa's contributions to this vital industry.
Understanding the need for all-weather and rubber cables
Our nation's diverse climate, ranging from scorching heat to torrential rain and even occasional cold spells, places extraordinary stress on cables and wires used in infrastructure projects. Traditional cables may degrade rapidly under these conditions, resulting in costly maintenance and potential disruptions in critical services.
All-weather and rubber cables are specially designed to withstand these harsh environmental factors. They exhibit remarkable resilience to temperature variations, moisture, UV radiation, and abrasion, making them the ideal choice for South African infrastructure projects. These cables ensure reliable electrical connections and signal transmission, even in the most challenging conditions, ultimately contributing to the longevity and efficiency of the infrastructure.

What is the minimum bending radius and what does this value tell me?
The minimum bending radius is the smallest possible radius to which the cable can be bent without damaging it. It is specified as a multiple of the cable diameter. The smaller the value, the more flexible the cable. There are several industry standards defining the minimum bending radii for different cable types. The values differ greatly, depending on whether the cable is used in a fixed or moving application. A drag chain cable of type MULTIFLEX 512-C-PUR UL/CSA, for example, has a minimum bending radius of 4 x d in a fixed application, but only 7.5 x d in moving one. The reason for this is that the bending stress in a permanently moving cable is significantly higher as the force and the direction of the bending motion are constantly changing. A suitable minimum bending radius is hence an important criterion when choosing cables and wires.
How can the flexibility of a cable be improved?
There are various ways to improve this, starting with using the best materials. In most cases, copper wires comprising of fine or finest stranded conductors are sufficiently flexible. Alloys can be used as well for some bespoke applications. Care must be taken that the insulation and sheathing materials are likewise flexible. The choice of materials makes a big difference, especially in applications at extreme temperatures. PUR or TPE sheathing are suitable for cold temperatures as they don’t get very stiff. The diameter and construction also have a major impact on the cable’s bending properties. The shorter the lay length, i.e., tighter twisting inside the core stranding, the more flexible the cable.
