Ex-Proof Sockets
Cable sockets with an interlocking disconnecting switch are suited for any explosive environment. They cannot be used in conjunction with industrial plugs. The colour of the ring identifies the rated voltage.
EPC and EPRC connections, with voltage ranges ranging from 63A to 125A, are ideal for power welding equipment,
compressors, generators, and big mobile equipment in general. Only when the plug is inserted can the circuit breaker be closed, and only when the circuit breaker is in the “open” position can the plug be retrieved.
Ex-Proof Plugs
Ex-proof plugs are moveable connectors attached to electrically powered devices, with the socket fixed to equipment or a
building structure and linked to an activated electrical circuit. The plug is a male connection with protruding pins that
correspond to the holes and female contacts in a socket. Ex-proof plugs and socket-outlets are products designed for potentially explosive atmospheres.
Ex-Proof Sockets with Circuit Breakers
Sockets with automatic circuit breakers are available in two or three pole types with an earth connection. When the plug is
inserted, it activates the internal circuit breaker, which powers up the device. This technique prevents arcs from forming between plugs and socket cavities and pins. The body, cover, and external handle’s material is aluminium alloy with a low copper concentration.
Ex-Proof Drain and Breather Valve
Breather drains enable pressure compensation between enclosures and surrounding atmosphere, thereby minimizing moisture build-up caused by temperature fluctuation and humid environments. Furthermore, they effectively drain any
condensed water present within the device.
Ex-Proof Sealing Nipples and Bushing
Sealing nipples and bushings are used to interconnect ex-proof enclosures. The cables are sealed through a bi-component resin set around each conductor.
Ex-Proof Electrical Fittings
Electrical fittings are components of full electrical pipe systems. Three-piece unions for gas groups IIb and IIC allow for
independent rotation and connection between pipes of electrical equipment and enclosures or various ex-proof equipment devices. Reducers and adaptors are used to connect equipment, enclosures, pipes, and hubs of various sizes and threads, whilst plugs are used to shut pipe ends and are built with hex socket heads to guarantee the opening is only accessible with appropriate tools. The range is completed by open elbows, sealing fittings, nipples, couplings, rigid and flexible tubes.
Ex-Proof Flexible Conduits
Ex-proof flexible conduits are used to connect offset equipment or devices subject to vibrations such as electrical motors. They are also useful for lighting fixture installation and as an alternative to rigid conduits when rigid conduits are difficult to install. Ex-proof flexible conduits are incredibly flexible and have a very good vibration dampening effect.
Ex-Proof Rigid Conduits
Rigid metal conduit, or RMC, is galvanized steel tube with threaded fittings that is installed. It’s generally used outside to shield electrical wires, panels, and other equipment from damage, and it can also offer structural support.
