    (Heat) shrink tubes

    hayk.avetisyan

      No subcategory for (heat) shrink tubes within the list of insulation types, while it's possible to create heat-shrink tubes in the component library, which is only possible to add when "Component" selected from the list of insulation types.

          Hi Hayk,

           

          you should define heat shrink tubes in VeSys 2.0 Components using the Group Name "Tube".  You should also set its Type Code to HSTB (or whatever is convenient) to identify the part as a heat shrink tube when searching.

           

          Then, in VeSys 2.0 Harness you place the heat shrink tube as a regular tube using the Add>Insulation Run facility.

           

          Also, you have noticed there is a Group Name for Heat Shrink Sleeve, in VeSys 2.0 Components - this is provided to define the heat shrink sleeves used to insulate splices.

           

          best regards,

            Ok, but I still think a heat shrink tube and a heat shrink sleeve are the same thing as we usually use certain type of heat shrink tube/sleeve for insulating splices, drains, conductors, bundles and/or cables. And I woulnd't like to add all heat shrink tubes (we use) twice in our VeSys database (as a tube and as a sleeve). That's the question now.

             

             

            But is this what you mean with a tube (fixed tube)?

              Hi Hayk,

               

              they are both the same type of physical object - as purchased from a supplier.  But the context of their usage is different on a real-world harness.  Sometimes we use the heatshrink tube as a short section to insulate a splice, sometimes we use a long section to provide waterproofing over a long section of a bundle.

               

              With both VeSys and Capital we provide specialised component "Groups" in the Component/Library - when you specify a part as belonging to a particular "Group" it will then be able to make use of specialised engineering proccessing when it is used in a harness design (this corresponds to the "context" of its usage that I mentioned above).

               

              So if you define a Heat Shrink Sleeve you will be required to specify information regarding the size and number of spliced wires it can accomodate, these attributes will be processed during the splice engineering phase of Harness Processing.  But if you want to specify a heat shrink as a bundle insulation then the correct Group to specify is "Tube" - this requires a different set of attributes to be defined and these attributes are processed during the insulation engineering  phase of Harness Engineering.

               

              On your example, you have created a 35mm long tube - you would use the same proces to create a longer heatshrink insulation run; you can then specify the part number from the library.  The library part should be specified with Group=Tube and part number corresponding to your heat shrink tubing.

               

              Best regards,

              John

                Hi John,

                 

                We use the same heat shrink tube (p/n Z347047 = heat shrink tube 35mm - 1 piece/unit) both for insulating splices and bundles. My question is if we have to add the same tube twice into the adatabase as a "Tube" and as a "Heat shrink sleeve".

                 

                Thank you

                  Hi Hayk,

                   

                  you will need to create two parts in the library - one for the Heat Shrink Sleeve, one for the Tube.  They will need to be defined with different part numbers to differentiate their definitions/usages in the harness.  The best way to do this is to use the same part number for both, except for the last character which should be different e.g. Z347047s for the Heat Shrink Sleeve and Z347047b for a bundle insulation Tube.  You will also need to do this for the corresponding Supplier Part Numbers defined in the Supplier tabs.

                   

                  best regards,

                  John
