Insulated Adaptor Type 777 with Flameproof Ex d IIC & Increased Safety Ex e II forms of protection.
The CMP Type 777 Insulated Adaptor allows the Metallic Cable Gland, and ultimately the cable armour, to be effectively isolated from the equipment. The use of these Adaptors has proven to be an essential precaution in areas where electromagnetic ‘noise’ and circulating eddy currents 'stray' around any vulnerable cable system. Particularly relevant in Power Plants and in areas where highly sensitive instrumentation circuits are relied upon for interference free safety critical operations, the cable armour can still be connected to ground externally with the use of an earth tag fitted between the cable gland and insulated adaptor. This allows the user to design his system around a single point earthing strategy and allows the operator to perform tests on the earth circuit without disconnection of the elements installed. A General Purpose Industrial version is also available.
CMP 777 Insulated Adaptors are available in Brass, Aluminium or Stainless Steel and can be supplied for both Industrial and Hazardous Area applications, with Ex ‘d’ & Ex 'e' Component Approval.
