Tamra Transformer Conductor is produced in every conceivable ambience (Moisture controlled Dust free) to churn out flawless and better than best Copper & Aluminium conductor; with varieties of Insulation in comprehensive- spread from Kraft Paper to Glass Insulation and from single conductor to bunched to meet up exact requirement.
Tamra Oxygen Free Copper Wire Rod with less than 5ppm generates highest purity Copper, embracing Vertical Upward Continuous Cast process. Exclusive usage of LME Grade A copper cathode and rigid process control helps Tamra to deliver a product which is a class apart. Tamra has successfully nurtured a rare capability to produce Silver Bearing Copper.
Rectangular: The continuous radial extrusion Conform process results into clean, deburred, smooth, round edged conductor’s soft conductor. Extrusions of both Copper & Aluminium are processed through superior Conform technologyto deliver best material.
Round: A scratch free annealed Copper / Aluminium wire are produced using the best European technology ensures Tamra to produce joint-less conductors of highest quality.
With a seamless bare conductor and with efficient insulating production line in a dust free moisture controlled atmosphere helps Tamra to guarantee a product ,which excels global standards.
The meticulous insulation line encompasses the gamut of transformer’s conductor like Kraft Paper, Crape Paper, Nomex, Mica, Polyster, Double glass and the variant of various insulation material required by the industry to meet varied applications.
Tamra is destined for ultimate success thru Quality Assurance right from Raw Materials to finished product passing through rigid quality checks of various electrical and mechanical parameters.
Tamra guarantees the super quality product through the stringent quality measures carried internally through its state-of-the-art lab, a few of which includes :
