Abstract
An electrical wire and a method of making the electrical wire are provided. The electrical wire includes a conductor and an electrically insulating covering on the conductor. The covering is a resin composition including a first polymer, a second polymer and filler particles. A good balance of properties is achieved. The electrical wire is suitable for use in a vehicle.
Claims14
An electrical wire, comprising:
- a conductor;
- and
- an electrically insulating covering on the conductor;
