What are the requirements for the use of flame retardant control flexible cables?

I. What are the requirements for the use of flame retardant control flexible cables? If the line length required for the use of shielded flexible cables is short, the shield can be single-ended, i.e., the metal shield will be directly grounded at one end of the shielded cable, and the other end will not be grounded or will be grounded through protection. The induced voltage corresponding to the length of the cable cannot exceed the safety voltage when both ends of the metal shield of the shielded cable are connected to ground. Because, shielded flame retardant control flexible cable metal shielding layer will not produce induced voltage, but the metal shielding layer by the interference flux will produce shielding loop current through, if the location A and location B of the potential is not equal, will form a large potential loop current, due to the presence of static induced voltage affects the stability of the entire circuit signals, and even produce antenna effect will be more than worth the loss.
