Cable Duct Or Trunking

The reason for selecting Cable duct ( with covers ) is the concern of EMI/RFI shielding protection for very sensitive circuits. A Cable duct with steel covers provides a good degree of shielding if there are no breaks or holes the completed installation.Some engineers and desighners specify Cable ducts (often with covers) in the belief that all electrical circuits have to be totally enclosed by metal.

The cable ducts are just supporting cables that are designed for such installations. Cable failures in cable in cable duct runs rarely happen. Cable failures due to cable support problems in cable duct are non-existent.
