There are a large nuer of adhesive types for various appliions. They may be classified in a variety of ways depending on their chemistries (e.g. epoxies, polyurethanes, polyimides), their form (e.g. paste, liquid, film, pellets, tape), their type (e.g. hot melt, reactive hot melt, thermosetting, pressure sensitive, contact, etc.), or their load carrying capability (structural, semi
How long should Main Protective Bonding Conductors be?
Comparing Table 1 with the 0.05Ω figure It can be seen in Table 1 that the 0.05Ω figure is acceptable for some cable sizes and lengths but not for others. The 0.05Ω figure used in Worked Example 1 resulted in a maximum length of 27.3 metres for a 10mm 2 copper main protective bonding conductor. copper main protective bonding conductor.
