Products Description

Aramid paper-covered wire is a specialty winding conductor with a copper core uniformly covered with aramid insulating paper. It is primarily used in high-temperature, heavy-load, and long-life electrical equipment such as transformers, reactors, and motors.

It combines the conductivity of a metal conductor with the high heat resistance, high mechanical strength, and excellent insulation properties of aramid paper, making it widely used in high-end electrical insulation applications.

Construction: Copper wire + aramid paper
Copper wire material: Copper flat wire/Copper round wire
Paper material: Aramid paper/Nomex paper
Heat resistance rating: H
Paper wrapping thickness and number of layers: Customizable according to customer requirements
Dimensional accuracy: ±0.02mm

Product advantages

Characteristics	Description
High Temperature Resistance	The temperature resistance grade of aramid paper can reach Class H (220℃), and it can withstand ≥180℃ during long - term operation.
Stable Insulation Performance	It has high dielectric strength (≥10 kV/mm) and stable performance in high - temperature, high - humidity and oil - immersed environments.
High Mechanical Strength	Aramid fibers have high strength, are resistant to bending and abrasion, and are not easily damaged.
Good Dimensional Stability	It does not shrink or deform at high temperatures.
Resistance to Chemical Corrosion	It has excellent tolerance to media such as oil, acid and alkali.
Wide Applicable Environment	It can be used for a long time in dry - type or oil - immersed insulation systems.
