现在没见过是可以理解,因为CCS规范里面就就没有涉及到这种电缆,你虽然翻阅几年了,也没见到,再说天天蹲在办公室,你见不着的。
“Cable support systems, which may be in the form of trays or plates, separate support brackets, hangers or ladder racks, together with their fixings and accessories, are to be robust and are to be of corrosion-resistant material or suitably corrosion inhibited before erection. The cable support system is to be effectively secured to the ship's structure, the spacing of the fixings taking account of the probability of vibration and any heavy external forces, e.g. where located in areas subject to impact by sea-water. ”
“Cables having an exposed metallic screen, braid or armour are to be installed in such a manner that galvanic corrosion by contact with other metals is prevented. Sufficient measures are also to be taken to prevent damage to exposed galvanised coatings during installation. ”
“ Non-metallic cable support systems and protective casings are to be installed in accordance with the manufacturer’s recommendations. The support systems and protective casings are to have been tested in accordance with an acceptable test procedure for:
Non-metallic cable support systems, protective casings and fixings installed on the open deck are to be protected from degradation caused by exposure to solar radiation.
Where the cable support system, protective casing or fixings are manufactured from a material other than metal, suitable supplementary metallic fixings or straps spaced at regular distances are to be provided such that, in the event of a fire or failure, the cable support system, protective casing and the affixed cables are prevented from falling and causing an injury to personnel and/or an obstruction to any escape route. Alternatively, the cables may be routed away from such areas.
The load on non-metallic cable support systems or protective casings is not to exceed the tested safe working load.
When a cable support system or protective casing is secured by means of clips or straps manufactured from a material other than metal the fixings are to be supplemented by suitable metal clips or straps spaced at regular distances each not exceeding 2 m and, for non-metallic cable support systems or protective casings, that used during safe working load testing.
Non-metallic fixings are to be flame retardant in accordance with the requirements of IEC 60092-101: Electrical installations in ships – Part 101: Definitions and general requirements, or an alternative relevant National or International Standard. ”
