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.

ZEN is available with an insulating arrangement to ensure that no contact is made between the earth circuit carried through the cable armour and the electrical enclosure which the cable enters. This isolation of the cable armour at one end of the cable is sometimes referred to as single point earthing. The ZEN range from CMP however allows more than a single point of earthing and delivering optimum safety.
