Single paper covered conductor is the winding wire made of bare copper (aluminum) wire, enamelled wire covered with special insulation materials. Multiple paper covered conductor is the winding wire made of several single paper covered wires or enamelled flat wires which arranged according to requirements, then covered with special insulation materials.
Single and multiple paper covered conductor are the important material for manufacturing transformers’ windings. They are mainly used to manufacture windings of power transformer, electric reactor and distribution transformer.
