Why TURBOLINE

  1. Repeatability

    Consistent Product Quality

    Wire that winds and performs the same way, batch after batch.

    Tolerance of 0.001 – 0.003 mm on bare diameter and 0.003 – 0.007 mm on overall diameter.

  2. Process

    Modern Manufacturing Facility

    An eight-stage enamelling process, from wire input to off-line spooling.

    24 machines: 18 FWD, 5 HEP and 1 RBD, at Rai Industrial Area, Sonipat, Haryana.

  3. Testing

    Advanced Quality Laboratory

    Dedicated instruments for the properties that decide performance in a winding.

    Spark, high-voltage and tensile testers, thermal shock oven, resistance meter and microscopy system.

  4. Control

    Strict Process Control

    Each enamel layer is applied with its own drying cycle, then cured in an integrated oven.

    In-process checks of colour, surface, OD, winding, oven temperature and online pin holes.

  5. Logistics

    Timely Deliveries

    A lead time of 5 – 7 days, with reels packed to arrive as they left the plant.

    Moisture-resistant polybags with desiccant, in corrugated export-quality cartons.

  6. Value

    Competitive Pricing

    Quotations against your size, grade and quantity.

    Custom sizes available on request.

  7. Supply

    OEM Supply Capability

    Spools, packing and enamel matched to how your line consumes wire.

    PT-4, PT-15, PT-18 and PT-25 spools; enamel from polyester to DC.

Detail E — Quality

Tested.Trusted.

  • Incoming inspection

    Aluminium rods are tested for purity, conductivity, UTS, elongation and diameter, and enamel / varnish for solid content and viscosity. Both are verified by a third party every six months.

  • Final inspection

    Appearance, surface, colour, winding, BD, OD, BDV, elongation, pin hole, heat shock, cut through, tan delta, flexibility and resistance.

  • Electrical testing

    Spark tester for pin holes and enamel imperfections. High-voltage tester for breakdown voltage and dielectric strength. Resistance meter for DC resistance.

  • Mechanical and thermal testing

    Tensile tester for tensile strength and elongation. Thermal shock oven for enamel adhesion and thermal endurance.

  • Enamel thickness

    Microscopy system for cross-section analysis of the enamel.

  • Standards followed

    ISO 9001:2015 quality management system. IS, IEC, NEMA, JIS and ASTM standards.
