The Journey of ExcellenceFrom Foundations toCorporate Leadership

High-quality enamelled aluminium and copper winding wire for demanding electrical and industrial applications.

Detail A — Company

Engineering Aluminium for the Future of Electrical Performance.

Esskay Wire & Cable Private Limited has made magnet wire since 2000: enamelled copper wire from the start, and enamelled aluminium wire since 2012. It is the conductor wound into the coils of transformers, motors and other electrical equipment.

A winding is only as good as its wire. Holding the conductor size steady and keeping insulation continuous along every metre is what lets a coil perform the way its designer intended.

Why Esskay

  1. Dimension

    Precision Manufacturing

    Conductor dimensions held to the tolerance a winding design depends on.

    Aluminium 0.150 – 1.000 mm, copper 0.060 – 1.000 mm. Tolerance: bare diameter 0.001 – 0.003 mm, overall diameter 0.003 – 0.007 mm.

  2. Repeatability

    Consistent Quality

    Every lot is expected to wind, insulate and perform like the one before it.

    Every thermal class is specified against 8 technical tests, including pin-hole, heat shock and cut-through.

  3. Process

    Advanced Production

    Drawing, insulating and spooling set up for controlled, continuous output.

    Our plant at Industrial Estate Barhi, Sonipat, in Delhi NCR, runs 48 machines: 33 FWD, 11 HEM, 2 RBD and 2 IWS.

  4. Logistics

    Reliable Supply

    Planned production and clear lead times so your line is not left waiting for wire.

    Installed capacity: aluminium 5,500 – 6,000 MT / year, copper 1,500 – 1,800 MT / year. Lead time: 5 – 7 days.

  5. Service

    Customer Focus

    Sizes, insulation and packing discussed against your application, not a catalogue default.

    Customised to order: size range, spool type, packing (polythene wrapper) and enamel, from polyester to dual coat (DC). Spool types PT-4, PT-15, PT-18, PT-25.

  6. Knowledge

    Engineering Expertise

    A team that speaks the language of conductor and winding design.

    26 years in magnet wire manufacturing. Technical support includes samples, customer trials, test reports and any other technical support.

Detail E — Quality

Quality WithoutCompromise.

  • In-process control

    Wire colour, surface, appearance, overall diameter (OD), winding, machine oven temperature and online pin-hole checks, among others, monitored during production.

  • Testing

    Each grade is specified for flexibility, coefficient of friction, elongation, adherence, pin-hole, heat shock, cut-through and tan-delta bending point.

  • Incoming inspection

    Aluminium rod and enamel / varnish are tested to our internal incoming inspection standards: aluminium for purity, electrical conductivity, ultimate tensile strength (UTS), elongation and diameter, among others; enamel for solid content and viscosity. Both are also verified by a third party every six months.

  • Final inspection

    Appearance, surface, colour, winding, bare and overall diameter (BD, OD), breakdown voltage (BDV), elongation, pin-hole, heat shock, cut-through, tan delta, flexibility and resistance, with further tests in our lab as the customer requires.

  • Traceability

    Every spool is labelled with its material, size, type, machine number (M. No.), shift, operator, spool type (PT No.), traceability ID and date, so each spool can be traced back to the machine, shift and operator that produced it.

  • Standards

    IS 13730, IEC 60317 and NEMA 1000, according to thermal class.
