CMP Installation Training
CMP Products is committed to providing a high level of technical support in relation to the supply of its products and offers site installation training as part of its value proposition. All personnel engaged to carry out work at an explosive atmosphere installation should possess the necessary skills, knowledge, experience and competency to perform their duties in a safe and productive manner. Part of the skill set required to achieve the best cable gland performance would include hands-on practical knowledge and experience of the particular product to be installed. The same would also be true for any type of installation which involved explosive atmospheres, and is not only confined to oil and gas facilities.
Read moreUnderstanding Sizing of Cable Gland Size 20
CMP cable glands provide an overlap in sealing range between sizes, but during selection it is advisable that the smallest cable gland size is chosen, provided that the cable fits comfortably into that cable gland size (ensuring it is not too close to the limits of the cable gland), taking into account any tolerance in the cable. It should be recognised that cables vary in their diameters from drum to drum, and there could easily be 1.0mm or more difference in the measurement of two samples (of the size in question) of the same specification cable. There are three cable gland size options with M20 threads shown in the CMP cable gland catalogue and they are presented in size order, beginning with the smallest size first and subsequently going up in size throughout the range.
