Electrical wire having resin composition covering

摘要

An electrical wire and a method of making the electrical wire are provided. The electrical wire includes a conductor and an electrically insulating covering formed on the conductor. The electrically insulating covering is a resin composition including a first polymer, a second polymer and filler particles. The first polymer has a higher bonding affinity to the filler particles than the second polymer. The filler particles are coated with the first polymer and the coated filler particles are embedded in a matrix of the second polymer. The electrical wire is suitable for use in motor vehicles.
