Mica Tape Wrapped Wire

Mica Tape Wrapped Aluminum Wire

Mica Tape Wrapped Aluminum Wire uses high-quality aluminum as the conductor. After annealing, the conductor provides good flexibility and ductility for wrapping and installation. The product is insulated with high-quality polyester mica tape or polyimide mica tape, tightly wrapped around the conductor with a controlled overlap, forming a reliable high-temperature-resistant insulation layer.

Compared with copper conductors, aluminum offers lower weight and material cost, making it suitable for weight-sensitive and cost-conscious applications.

Product Overview

Conductor

Made from high-quality electrical-grade aluminum rods, with conductivity exceeding 62% IACS after annealing. The annealed aluminum conductor offers good flexibility and ductility for wrapping and installation, while providing a lightweight, cost-effective alternative to copper.

Winding Requirements

Rectangular conductor thickness ranges from 0.80–12.00 mm, with widths of 3.00–25.00 mm. The width-to-thickness ratio is ≤ 20, and the maximum cross-sectional area is 200 mm². Round conductor diameters range from 2.00–5.00 mm.

Insulation

Uses high-quality polyester mica tape or polyimide mica tape, tightly wrapped around the aluminum conductor with a controlled overlap to form a reliable high-temperature-resistant insulation layer.
