A Guide to Exd & Exe Reducers & Adaptors

A Guide to Exd & Exe Reducers & Adaptors

EX & EXE Reducers & Adaptors & Stopping Plugs

In the world of hazardous area electrical installations, understanding the role and functionality of Exd and Exe adaptors and reducers is crucial for ensuring safety and compliance. This blog aims to demystify these components, explaining their purpose, differences, and the contexts in which they are used.

What are Exd and Exe Adaptors and Reducers?

Exd and Exe stand for two types of protection methods used in electrical installations in hazardous areas. Exd refers to "flameproof" protection, while Exe signifies "increased safety" protection. These terms are vital in the context of preventing the ignition of surrounding explosive atmospheres in industrial environments.

Adaptors and reducers are components used to connect dissimilar thread forms or sizes in electrical installations. They are particularly important in hazardous areas where maintaining the integrity of the enclosure is crucial.

Adaptors (Enlarger)

Are used to increase the entry thread size, effectively enabling a larger gland or fitting to be attached to an enclosure with a smaller thread.

Reducers,

Conversely, reduce the threaded entry diameter of an enclosure, allowing for the attachment of a gland or fitting with a smaller thread.

Application Areas

These components are essential in various industries where hazardous conditions exist, such as:

Oil and Gas: In environments where there is a high risk of explosions due to the presence of flammable gases or liquids.

Mining: Given the combustible dust and gases present, electrical installations require stringent safety measures.

Marine: On ships or offshore platforms, where saltwater can corrode standard components and spark risks are high.

Pharmaceuticals, Power Generation, and Aviation: Industries where even a small spark can lead to significant hazards.

Material and Design Considerations

Raxton adaptors and reducers are made from materials like brass, stainless steel, and aluminium, brass nickle plated, & nylon catering to different environmental conditions and requirements. They come in various types, including male-to-female, male-to-male, and female-to-female configurations, with options for hexagonal or round bodies depending on space constraints.

Explosion-proof or Flameproof?

The terms "explosion-proof" and "flameproof" are often used interchangeably in different regions. In North America, "explosion-proof" is commonly used, whereas "flameproof" is the preferred term internationally. Both refer to the ability of an enclosure to contain an internal explosion without igniting a surrounding explosive atmosphere.

 

Differences Between Adaptor and Reducer

The primary difference between an adaptor and a reducer lies in their thread sizes:

Adaptors typically have a smaller male thread than the female thread, used where the size of the connection device or cable gland is larger or equivalent to the conduit entry thread of the enclosure.

Reducers have a larger male thread than the female thread, used where the connection device or cable gland is smaller than the conduit entry of the enclosure.

Cable Glands & AC Cable Solutions plays a pivotal role in the distribution and supply of Eaton / Raxton, Redapt & capri products, serving as a crucial link in the supply chain for industries requiring hazardous area electrical solutions. Here's how they contribute to the industry:

Different Threads

In the realm of hazardous area electrical installations, the compatibility of thread types between equipment and accessories like cable glands, adaptors, and reducers is paramount. Cable Glands & AC Cable Solutions, being a key distributor for Eaton / Raxton and Redapt products, offers a comprehensive range of these components catering to various thread types. Understanding these thread types is essential for ensuring proper connections and maintaining the integrity of explosive-proof or increased safety installations. Here’s a breakdown of the different thread types you'll encounter with the range of reducers and adaptors:

Metric Threads

Metric threads are standardised threads used globally, characterised by their pitch in millimetres. These threads are common in most parts of the world and are used in a wide variety of electrical equipment and enclosures. The designation "M" followed by a number (e.g., M20) indicates the nominal outer diameter in millimetres. Metric threads are known for their precise thread pitches, which facilitate uniformity and ease of use in international applications.

NPT (National Pipe Thread)

NPT is a U.S. standard for tapered threads used to ensure a tight seal between threaded pipes and fittings. NPT threads are designed to create a seal when threaded together, making them ideal for applications involving liquids or gases. The taper on NPT threads allows them to form a seal when torqued as the flanks of the threads compress against each other, unlike straight thread standards that may require additional sealing methods.

BSP (British Standard Pipe)

BSP is another widely used thread type for connecting pipes and fittings, prevalent in the United Kingdom and many other countries. There are two types of BSP threads: BSPP (parallel or straight) and BSPT (tapered), which serve different sealing mechanisms. BSPP threads are sealed with a gasket or O-ring, while BSPT threads create a seal through thread engagement, similar to NPT.

ET (Electrical Thread)

ET thread is a specific type of thread used predominantly in electrical fittings and enclosures. It is similar to the BSP standard but is tailored for electrical conduit and accessory applications. ET threads are designed to ensure a secure fit and safety in electrical installations, particularly in hazardous areas where gas or dust may be present.

PG (Panzer-Gewinde)

PG threads are a type of conduit thread used primarily in Europe before the widespread adoption of metric threads. The term "Panzer" refers to armour, indicating the thread's initial design for armoured cable fittings. PG threads have a different pitch and shape compared to metric and are specified by a number that does not directly correspond to the thread's diameter.
