Toroidal Core Dealers in Mumbai

Permanent Magnets Ltd. (PML) supplies Cut cores in soft magnetic Nickel alloy material to industries requiring High accuracy flux Concentrator used in current sensing application. Depending on the application, customer can select suitable Nickel or Silicon Iron alloy. PML maintains close control of magnetic properties by properly heat treating in a controlled hydrogen atmosphere furnace, which permits the most economical and efficient design for transformers. PML manufactures Cut cores in Toroid and Rectangular shape. The cut cores are made robust by finishing them with varnish coating.

We are offering torrodial core. torroidal cores are round or rectangular shaped cores manufactured from crgo steel to be used in current and potential transformers (cts and pts ). Our torroidal cores are manufactured from the very best crgo steel and are annealed in a pit furnace to 820°c for a full cycle of 14 to 15 hours. The critical guaranteed values of our torroidal cores are: grade guaranteed no load current ( at 1.5 tesla 50 h2 ) hi - b grades 0.28 at / cm m4 0.32 at / cm m5 0.36 at / cm m6 0.42 at / cm grade colour (if required) hi - b grades brown m4 green m5 black m6 grey at / cm = ampere turns per centimetre. 100% of our cores are tested before dispatch so that our customers get only those cores which are better than the above guaranteed specs. We also paint the cores so that the colour indicate the grade of the core. The colour coding is as follows.
