  • I personally do not have this information.

    Please start a new thread on this subject in the Supplies and Equipment Technical Division.

    Thank you.

  • Hello Udaya,

    Well let's think about your question for a minute.

    1 - There are likely millions of oil filled transformers around the world and mostly all contain enameled coated wires to step-down voltages.
    2 - There are many different manufacturers of transformer oils around the World and although these oils are all very pure, it is important to determine which one(s) you are dealing with.
    3 - There are many different manufacturers and types of magnet wire coatings throughout the World so it is important to determine the manufacturer(s) and coatings you are referencing.
    4 - It is likely that your magnet wire coating manufacturer(s) already have the information you are seeking so it is important that you provide them with specifics so they can answer your query properly.

    You should be able to easily determine the proper and specific answer for your customer.

  • Dear All,
    My name is uday ,One of our customer is asking about the compatibility of enameled copper wire with transformer oil. I have little knowledge on the magnet wires. Please suggest or help me on this matter.

  • Peter J Stewart-Hay replied to the topic 'Increase in weight after bunching' in the forum.
    In double twisting, you can have a bunch of strands randomly moving about in the finished conductor. Is this what you are doing? It is called double twist bunching.

    Likewise in double twisting, you can have a series of strand layers, each closed to control the position of the strands in each layer. Perhaps this is what you are doing. It is called double twist stranding.

    In either case, there is excess length in the strands to account for the twist (s) in the conductor. By determining the angle of the conductor twist, use the Pythagorean theorem to account for the excess length in the bunched strands as above and sum to obtain the conductor weight. ( en.wikipedia.org/wiki/Pythagorean_theorem )

    In case of double twist stranding, use the angle of strand twist for each layer of strands and sum the weight of each layer to obtain the conductor weight.

  • Mr Prasd KLN replied to the topic 'Increase in weight after bunching' in the forum.
    Dear Sir,
    How can i Calculate increase in weight of the conductor after bunching of the conductors. Suppose 140 wires bunched in double twist machine with wire dia 0.285. Calculated weight will be 79.4 Kg/Km. But What will be the increase in weight after bunching.

    Regards
