Thickness of each is 0. Other grades used include H50, isonfl. Core made up of magnetic materials composed of oxides containing ferric ions as their main constituent. Ionel is the first winding, but may be split in two or in rare cases be the final winding. Absorbent thin brown paper used normally to stabilise and separate the layers in small high voltage transformers.
Usually used to cushion larger diameter wires where the pressure from these wires would normally damage and penetrate other types of insulation.
Any taps are shown at intermediate figures. A walled former with a central hole sized to fit a specific lamination type and stack. Refers to mylar ksonel insulation inserted between the bobbin and laminations,to provide increased insulation, where: Composite moulded construction of compressed ferrite granules. Used as insulation mostly between windings and as an outer wrap.
Schenectady Air-Dry Varnish data sheet
Lamination material arranged with appropriate insulation to vary and control the magnetic circuit of the transformer. This strengthens the leadouts and protects against accidental access or damage to the higher voltage windings. Usually nominated as a thickness —eg. 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.
TPL is the number of turns of wire including enamel insulation calculated to fit into one layer. Winding wire having only ONE layer of protective enamel winding coating lower electrical insulation. SHUNTS Lamination material arranged with appropriate insulation to vary and control the magnetic circuit of the transformer.
Exiting self-leads for termination are twisted over themselves several times to strengthen wire and prevent breakage. 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.
They are not necessarily connected together. The actual insulation properties of this paper are not high. Can also get Grade III. On winding sheets this will also include core type or any reference to the type of magnetic circuit. A protective fuse wound-into or placed on top of a winding, usually the primary. A container into which a transformer is inserted for sealing and mounting in a resin.
Standard size of a lamination eg. Similar properties to steel laminations but having a magnetic circuit that is more suitable for higher frequencies.
IN-889B – Flow Transmitter:
Each material give the core distinctly different magnetic properties. Once heated to this temperature, the fuse becomes useless and the transformer must be replaced or rewound. Polyester Thermosetting Tape which is the standard in the industry for use in transformers. Grain Oriented steel which is typically 0. To seal a transformer in a coffin using epoxy or other resin. Any variations of this will be specified. Most possible faults but not all will show up as a higher than 64 current.
TAP An intermediate point in a winding brought out for termination. Thicknesses normally available range from 0.
Electrical grade Insulating paper. Usually used to describe layer winding — but can be Useful for bobbin winding to estimate winding progress.
Glossary Marque Magnetics
Used in situations where high temperatures would prevent use of normal insulations. There can also be electrical advantages to encapsulating. Means tubular PVC or woven fibre placed around the winding wire for additional protection and insulation. Means filling the specified bobbin side-slots usually high SIDE-SLOTS voltage or primary side with a thickened opaque mixture of epoxy resin after final assembly and varnishing. A layer 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.
This allows for a JUMBLE type winding that is always contained and insulated from the laminations by the bobbin walls. Sizes normally available are 0. Winding wire having TWO layers of protective enamel coating higher electrical insulation. An identifiable feature on a bobbin that is used as a DATUM for the orientation of terminations and windings, etc.
