What is Explosion Proof (Ex-Proof)?

Nov 09, 2021

What Is Explosion Proof? The concept of explosion proof does not mean a product can withstand any external explosion. For a product, such as explosion proof junction boxes to be classified as explosion proof it would have to be able to contain any explosion originating within the housing due to any sparks from within and prevent igniting vapours, gases, dust or fibres in the air surrounding it. For safety reasons, when equipment is based in hazardous areas, it ... Read More

What are self-regulating heating cables

Nov 08, 2021

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

Aug 30, 2021

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

Jul 30, 2021

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
