Since accelerators are constructed with the latest technology,their specifications are frequently upgraded.Many kinds of cables such as high current power cables and low noise signal cables are used in the accelerator systems under special restrictions.The power cables for magnets are significant as most of them feed high current with low voltage.Sometimes they are massive because transmitting large kilo amperes requires many large cross section cables aligned parallel.These cables run through radiation shielding walls which could cause heat problems.In this paper,the author will mainly describe custom-made cables used in some accelerator facilities.
