  • SF6 gas recycling centre to lower carbon emissions and generate cost savings
    SF6 gas is extensively used in the electrical industry for dielectric insulation and current interruption in circuit breakers, switchgear and other electrical equipment. Using recycled SF6 gas will help reduce carbon emissions and could result in a cost-saving potential of up to 30%.
  • The power of copper
    Man first came to understand the value of copper around 10,000 BC. The Romans, Greeks, Aztecs and Egyptians were quite innovative in their use of copper and copper-tin alloys such as bronze and brass. The metal was readily accessible, very ductile and malleable, making it relatively easy to smelt. It also had a natural resistance to corrosion. The current extraordinary rate of development in China and India has significantly increased the demand on this resource, driving the cost of copper to record levels. As the lifeblood of all electrical systems, it is essential that designers and engineers are efficient in their use of copper to produce an economical solution without jeopardising the integrity of the electrical supply system.
