CMP PRODUCTS CABLE GLANDS AND CONNECTOR SPECIALISTS - GLOBAL PRODUCTS FOR GLOBAL APPLICATIONS Sealing cables in hazardous areas Electrical power, control and instrument cables are manufactured to a host of different national and nternational construction standards. The matter of correctly sealing these cables as they enter hazardous area electrical equipment is an essential safety requirement the world over. Ensuring that the nstalled cable entry maintains the protection method of the associated equipment is a safety critical aspect of the installation which should not be treated lightly....

What issues exist with Barrier Gland installations? Traditional barrier type cable glands employing epoxy/clay based sealing compound have been used in hazardous areas for many years to provide effective explosion protection. The barrier material is a two part formula that needs to be mixed thoroughly on site at each cable end before application. This is not only time consuming but requires extreme diligence. However a certain degree of risk is associated with this traditiona nstallation process and this risk increases with the number of conductors in multi-core cables The standard...

CMP PRODUCTS CABLE GLANDS AND CONNECTOR SPECIALISTS - GLOBAL PRODUCTS FOR GLOBAL APPLICATIONS A revolutionary sealing solution for barrier glands that delivers increased reliability is a Liquid Pour, Fast Curing, Liquid Resin Seal that installs in seconds and cures in minutes. Its unique formula begins with a low viscosity liquid that flows Into the cable interstices completely surrounding the cable conductors, driving out the air in the process The viscosity then increases and completely cures in minutes, dependant on ambient temperature (see comparison graphs on page 5). RapidEx benefits...

CMP PRODUCTS CABLE GLANDS AND CONNECTOR SPECIALISTS - GLOBAL PRODUCTS FOR GLOBAL APPLICATIONS Easy application This comparison shows the time required to mix and apply barrier materials on a range of multi conductor cables, using either Clay Based Epoxy Compound or RapidEx Liquid Pour Resin. This outlines the fact that the application of the RapidEx liquid pour resin is easier than traditional methods Faster curing One of the many advantages of using the RapidEx liquid pour resin is the time saved in the completion of the cable installation, due to the fast curing formula This means that...

CMP PRODUCTS CABLE GLANDS AND CONNECTOR SPECIALISTS - GLOBAL PRODUCTS FOR GLOBAL APPLICATIONS Do all Barrier Glands provide the same function? h theory the principal of a barrier gland is the same for all comparable products, in that the equipment form of protection is common (e.g. Ex d IIC), given that the certification standards used are identical. However in practice not all barrier glands achieve the form of protection in the same subtle manner, even if the certification appears to have similarities. When barrier glands first came on the market it was quickly identified that they needed...

CMP Barrier Glands using RapidEx Every barrier gland product supplied by CMP with RapidEx liquid pour resin, has an internal flameproof joint, enabling the cable to be easily disconnected and the assembly inspected. This arrangement is certified to both the I EC installation system (Ex d), nstallation systems (Class I Division 1 and Division 2). The outcome of this is a range of products that can be selected for global applications without the need to specify or order different products for different RAPIDis available with the following CMP cable gland types *Cable types (SWA and Unarmored)...

CMP PRODUCTS CABLE GLANDS AND CONNECTOR SPECIALISTS GLOBAL PRODUCTS fOR GLOBAL APPLICATIONS Selection process selection process is concerned, as a barrier gland may automatically be required. The need for barrier glands to be used in a given situation depends upon several factors, as stated in the prevailing installation standards, e.g. IEC 60079-14, which of course will be subject to change from time to time. Taking into account a diverse range of variables, such as equipment configuration, location, gas group etc, the one over-riding constant factor that must be considered in the...

Here are the general requirements for selection of cable glands for hazardous locations :- These codes require that any cable for use in a Hazardous Location must firstly be permitted for use in that location, and secondly be tested and approved or listed for the application. Consequently cable glands intended for use in Hazardous Locations, must also be tested and approved or listed for use in a specified location, in conjunction with a specified and approved or listed cable type. Cable Wiring Methods The use of flexible cables in North America has provided industry with a wide choice of...
