Description
S1BC4N8-F Round flexible electric cable, with special rubber insulation and outer sheath, suitable for permanent immersion in drinking water. The cables have successfully passed rigorous testing of drinking water requirements of the British WRAS certification (according to BS 6920), the German KTW and W270 for direct and permanent immersion in potable water. The certification agencies have verified the absence of microbial growth, the water taste, appearance, transparency and colour and the absence of any metals or toxic substances. For making connections to electrical equipment used in a waste-water environment and subject to medium mechanical stress, e.g. submersible pumps in sewage disposal and treatment as well as submersible mixer. Especially for frequency converter controlled AC drives and if considerable demands in respect of electromagnetic compatibility (EMC) according to the EMC directive imposes. For an effective shielding both ends of cable must have a good shield contact to ground. Owing to the various (and frequently changing) substances of which the contaminated water is made up, the cables may be used only in easily accessible areas that can be inspected (installation depth of approximately 10 m, as customarily encountered in sewage water tanks). These cables are also suitable for use in process water, cooling water, mine surface water, rainwater and combined waste water. Under certain circumstances they can be suitable for groundwater and seawater; it is possible to impose less stringent specifications in terms of accessibility and inspection. In such cases the cables can be used at depths up to 500 m. If the water concerned is aggressive or composed of special substances, the cables resistance properties should be examined. These cables can be used indoors, outdoors, in explosion-hazard areas. In other respects, DIN VDE 0298-300 / HD 516 applies
