The mining sector has always been under pressure to utilise natural resources efficiently. Projects such as ‘The Mine of The Future’, Rio Tinto’s iron ore mine in Western Australia, not only focus on efficient extraction of material, but also the automation of equipment, energy efficient systems and management of natural resources. This is viewed by some as the most advanced mine in the world. Rio Tinto stated that the project is not about a single mining site, rather, it is the approach they use across Rio Tinto to find new ways that will help them to maximise resources, recover more from increasingly difficult deposits, and above all, do it safely.
It is now evident that the South African attitude towards efficiency and sustainability is undergoing transition. Energy and waste water policies are changing through collaboration between stakeholders and the social and environmental impact legislation.
BKW’s cable design and development
As a company committed to developing and manufacturing electrical cable solutions for various sectors in South Africa and the rest of the world, BKW recognised the value it could add for industry. As a result, it has developed a range of specialist products suitable for use in mines, offshore mining operations and water management plants.
The challenge was to develop products that could offer a solution specific to the needs of the mining industry. This meant quality products suitable for mining applications, which include power, control and data cable. The industry also demanded products that are designed for the conditions they will be subjected to, such as exposure to salt or fresh water, fuel and chemicals. The cables needed to be rugged, flexible and made from high quality materials, to increase their lifespan under these harsh conditions. In addition, such cables needed to comply with local and international standards and specifications.
Health and safety
As safety is a high priority for BKW and the industries it serves, products comply with the Restriction of Hazardous Substances directive (RoHS). The products do not contain lead or other hazardous substances, making them suitable for use in public transport, water purification plants and even the food industry.
Fire resistant cables are designed to ensure the integrity of the electrical current or signal during a fire. They are used in offices, mines, tunnels, railway stations, or with critical equipment such as alarm, traffic and fire-fighting systems. The materials used in fire resistant cables are halogen free, non-toxic, low smoke emission and fire retardant.
BKW’s range of instrumentation cable is used in many applications, including: temperature measurement and control in ovens, furnaces and foundries; video, data and communication; utility control; video monitoring of traffic and the control of traffic signals.
In addition, a range of waterproof, abrasion and pressure resistant cables is used by several mining operations in South Africa and neighbouring countries. The range is also suitable for use in offshore applications and submersible installations.
