130/155 Class Polyester Enamelled Aluminium Round Wire

Chalco's independent enameled wire production line has international ISO 9001, CQM, and SGS certifications. Enameled wire products comply with IEC-60317, GB/T, JIS, NEMA, RoHS standards, and have passed UL (E234565) certification.

Adopting advanced mold painting technology to solve problems such as eccentricity in felt painting and uneven pressure resistance. The paint film has good adhesion, the wire has uniform diameter and good pressure resistance. The elongation rate is up to 45%, thus the round wire can be flattened into enameled aluminum flat wire.Welcome contact

Features of Chalco 130/155 class polyester enamelled aluminum round wire

The surface is free of pinholes, burrs, paint flow, and aluminum leakage.
Good corona resistance, excellent softening and breakdown performance, and excellent overload resistance.
The elongation of the round wire is good, with a flattening degree of 25-45%. After flattening, the paint surface does not crack, and the groove filling rate is high.
Mold painting, uniform baking temperature and film thickness, and uniform voltage.
The wiring is well arranged and there are threading holes left, no backline during use, improving the safety of electrical circuits.

Aluminum enameled wire also has some limitations, such as poor hydrolysis resistance (attention should be paid when used in enclosed motors and electrical appliances); Grade 130/155 polyester enameled aluminum round wires are not suitable for use in high-efficiency motors.Quick Quote
