SILVYN® Flexible Conduit
A: SILVYN® cable protection conduit systems can provide protection against external influences (mechanical, chemical, electrical). SILVYN® HIPROJACKET even protects the cable against fire or liquid metal, however the conduit cannot prevent the temperature inside the conduit being heated up. In other words, protection conduits can ward off sources of heat but they cannot actively cool the temperature.
A: SILVYN® CHAIN energy guiding systems are a versatile and comprehensive range which includes both plastic chains and steel chains. This means that incorporating it into the general product range would entail an additional 200 pages in the catalogue. In addition to this, the SILVYN® CHAIN article numbers are issued on an individual customer basis, because each chain system contains different lengths and components.
A: The correct locknuts for conduit glands are located in the catalogue section for cable glands, plastic locknuts in SKINTOP® metallic locknuts under SKINDICHT®.
A: There is no general and accessible CE certificate for conduit protection systems, they have to be requested and made separately from Product Management or technical department.
A: All plastic conduits, which are marked as UV-resistant. For metallic conduits the corrosion resistance must be considered, the customer must be fully aware of the application area involved. The most reliable choice amongst metallic conduits are the stainless-steel conduits because they are made of rust-resistant steel. There is no general and accessible CE certificate for conduit protection systems, they have to be requested and made separately from Product Management or technical department.
A: A cable gland was developed to clamp and seal cables that have a solid core (made of copper). SKINTOP®, in particular, has products with a variable clamping range, which enables the use of different cable outer diameters. When using SKINTOP® cable glands with a protection conduit, the protection conduit may end up being pressed-in, nor can connections be guaranteed to have a high tensile strength. SILVYN® conduit glands by contrast are always designed for a specific conduit size, and they only provide a connection option for this particular conduit size coupled with the appropriate sealing capability.
A: Cable protection conduits can also be installed in hazardous areas if their electrical conductivity is taken into consideration. Only electrically conductive outer materials may be used so that no sparking occurs in the event of any friction between two non-conductors. These sparks could lead to an explosion in a hazardous area. Fully-metallic conduits can be used in hazardous areas without any problems. Conduit glands require ATEX approval and they must pass hardness tests as with SKINTOP® cable glands for ATEX areas.
A: When the corresponding thread sizes are taken into consideration, locknuts and adapters from the SKINDICHT® range of accessories can be used.
A: Screwed conduit glands have been specifically designed and tested for conduit sizes (inner and outer diameters) and conduit structure (e.g. corrugated conduit). The properties for conduit glands listed in the catalogue can only be achieved if the gland can be used together with the protection conduit.
A: With SILVYN® cable protection conduit systems the UL certificate can best be found on the homepage www.UL.com and the "CERTIFICATIONS" will take you to a selection screen. In UL FILE NUMBER one can enter the list number of the UL certificate to have it displayed. For SILVYN® cable conduit protection systems the UL number is E308201.
A: Cable conduit protection systems are generally bonded and welded ring packaging, which cannot be stocked in our warehouse as cut-length orders. It is also possible for customers who wish to have a sample conduit for material sorting purposes, to have it delivered through the sample warehouse. A representative size is available here as a 0.4 M meter long sample. Sample article numbers always bear an M for sample instead of the first number of the item number.
A: AGRAFF Profile refers to the double folding of metallic protection conduits. Unlike in the single "hook-in principle" the conduit is not folded just once, but hooked into itself through an additional operation step. This double fold gives the conduit higher stability, which in turn is why protection conduit with the AGRAFF profile can be subjected to higher mechanical loads than conduits that are hooked in once only. In the SILVYN® product range, the UI511 stainless-steel protection conduit is manufactured according to this principle.
