High-quality enamelled aluminium and copper winding wire for demanding electrical and industrial applications.
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.
Round aluminium conductor with a polyester, polyesterimide or dual-coat enamel, in four thermal classes from 130 to 200.
Round copper conductor with a polyester, polyesterimide or dual-coat enamel, in four thermal classes from 130 to 200. Made by Esskay since 2000.
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.
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.
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.
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.
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.
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.
Copper or aluminium input material.
Preparation of the rod before drawing.
Reducing the conductor to its finished size.
Applying the enamel insulation coat.
Spooling the finished wire for despatch.
Checking dimensions, insulation and finish.
Labelled, packed and ready to ship.
Wire colour, surface, appearance, overall diameter (OD), winding, machine oven temperature and online pin-hole checks, among others, monitored during production.
Each grade is specified for flexibility, coefficient of friction, elongation, adherence, pin-hole, heat shock, cut-through and tan-delta bending point.
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.
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.
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.
IS 13730, IEC 60317 and NEMA 1000, according to thermal class.
Specified values for this class. See every class on the products page.
