isonel+ datasheet & applicatoin notes – Datasheet Archive
They are not necessarily connected together. A issonel of copper shim, generally the full-width of the bobbin, or a specified widthwound as ONE complete turn and insulated from the windings either side.
Usually used to cushion larger diameter wires where the pressure from these wires would normally damage and penetrate other types of insulation. Absorbent thin brown paper used normally to stabilise and separate the layers in small high voltage transformers.
Composite moulded construction of compressed ferrite granules. A protective fuse wound-into or placed on top of a winding, usually the primary. Thickness of each is 0.
Core made up of magnetic materials composed of oxides containing ferric ions as their main constituent. Means filling the specified bobbin side-slots usually high SIDE-SLOTS voltage or primary side with a thickened opaque mixture of isknel resin after final assembly and varnishing. Sizes normally available are 0. Refers to mylar sheet insulation inserted between the bobbin and laminations,to provide increased insulation, where: Standard size of a lamination eg.
This is usually done to provide the transformer with a weather or damp-proof seal or to provide both a form of mounting and security against movement or vibration. Any taps are shown at intermediate figures. Once heated to this temperature, the fuse becomes useless and the transformer must be replaced or rewound.
Any variations of this will be specified. Lamination material arranged with appropriate insulation to vary and control the magnetic circuit of the transformer. Each material give the core distinctly different magnetic properties. Exiting self-leads for termination are twisted over themselves several times to strengthen wire and prevent breakage. Usually nominated as a thickness —eg.
Grain Oriented steel which is typically 0. There can also be electrical advantages to encapsulating. Used as insulation mostly between windings and as an outer wrap.
Polyester Thermosetting Tape which is the standard in the industry for use in transformers. A container into which a transformer is inserted for sealing and mounting in a resin. A magnetic core consisting of a circular ring of iron powder, ferrite, steel or other material.
Usually used to describe layer winding — but can be Useful for bobbin winding to izonel winding progress. Layer winding as opposed to jumble winding is done by using a manufactured former and winding successive layers in such a way that: An identifiable feature on a bobbin that is used as a DATUM for the orientation of terminations and windings, etc.
IN-889B – Flow Transmitter:
Also known as spaghetti. On winding sheets this will also include core type or any reference to the type of magnetic circuit. Similar properties to steel laminations but having a magnetic circuit that is more suitable for higher frequencies.
This allows for a JUMBLE type isoel that is always contained and insulated from the laminations by the bobbin walls.
Most possible faults but not all will show up as a higher than expected current. Other grades used include H50, etc. Tongue is one dimension of the interior rectangle, stack total thickness is the other. Usually is the first winding, but may be split in two or in rare cases be the final winding.
TAP An intermediate point in a winding brought out for termination. To bring the leads up along the side of the bobbin, or up ON TOP through the slots, to be terminated on top of the winding with external leads and using woven sleeving.
Means tubular PVC or woven fibre placed around the winding wire for additional protection and insulation. Used in situations where high temperatures would prevent use of normal insulations. Winding wire having TWO layers of protective enamel coating higher electrical insulation. SHUNTS Lamination material arranged with appropriate insulation to vary and control the magnetic circuit of the transformer.
A walled former with a central hole sized to fit a specific lamination type and stack.
