Characteristics of "cold flow" in accordance with the standards iec 60331 and iec 60332 in some cables are subject to additional requirements fire and . Most of the cables of this type have the characteristic "cold flow" cushion the inner shell. This means that when a certain pressure to the shell, for example, causes contraction of the inner membrane seal compression type, the material properties of the data flow, which leads to a violation of the effectiveness of sealing. Paragraph 9.1.3 "Building Regulations" (UK) en 60079-14: 1997 / iec 60079-14: 1996 prohibits the use of cable glands to seal compression type cable with a characteristic "cold flow". Cable gland 501/453/Universal company Hawke has an inner shell diaphragm seal type, fully meet the above requirement of "Building Regulations" and has minimal pressure on the inner shell cable entry. Seal does not damage the cable jacket material ("Cold flow"), but supports the corresponding class of ip and explosion. Why is it important to choose the right type of cable glands? Proper installation.
Only specially trained craftsmen to guarantee the correct installation of cable glands. The world's major contractors and the contractors follow the professional level of employees, and in most cases the requirement is to obtain a certificate recognized by prestigious courses, for example, CompEx. However, not all countries, this requirement is mandatory. It is therefore important that the procedure for assembling the selected type of cable glands was fairly simple, with each entry was applied detailed instructions for assembling and sealing gaskets can be easily checked at each stage of assembly.
