What are self-regulating heating cables
Introduction Self-regulating heating cables are easier to use and implement as compared to other heat-tracing technologies. They incorporate a heating element that is made up of a polymer core and two parallel conductors. As the surrounding atmospheric temperatures around the cable decreases, the conductive core contracts on a microscopical level, decreasing the electrical resistance and creating numerous electrical paths between the conductors and when electrici...

Different approaches to explosion protection in hazardous areas
Introduction There are various methods to greatly reduce the risk of an explosion happening in hazardous areas. The key objective of these methods is to remove one (or more) components from the “Fire Triangle” and to prevent an explosion from occurring. The fire triangle as per below shows the 3 components needed for combustion and to prevent an explosion, these 3 components must not exist near each other. Source: https://www.safeopedia.com/defin...

What are terminal and control boxes
Introduction What are terminal and control boxes and their purpose? The main purpose is that terminal/control boxes house and protect electrical connection points for multiple wires. They come in various sizes and are made of various materials such as glass-reinforced polyester (GRP). For durability, stainless steel screws are usually used for any fixtures within the boxes. A key point is that these boxes are highly customizable with different sizes, different swi... Read More
Explosion Proof Enclosure or Intrinsically Safe Enclosure – Which is Better?
Explosion Proof Enclosure or Intrinsically Safe Enclosure – Which is Better? Explosion proof enclosures and intrinsically safe enclosures are becoming increasingly important as businesses look to minimise the risk of explosions in hazardous areas. It is very common for flammable gases or vapours to be present in many industrial, chemical and oil production environments. As such, there will always be a risk of the destruction of facilities and t... Read More
