A paper insulated copper conductor is an electrical cable that uses copper as the conducting material, enveloped in paper insulation. Copper is chosen for its superior electrical conductivity, durability, and flexibility. The paper insulation around the copper core is impregnated with dielectric oils or synthetic compounds, enhancing its electrical insulation capabilities and providing resistance to moisture.
Application
These conductors are commonly used in high-performance electrical infrastructure settings, including:
- Electrical power transformers
- High-voltage underground and submarine cables
- Distribution networks where long-term reliability and high electrical efficiency are crucial.
Type
There are several types of paper insulated copper conductors, classified based on their construction and the specific characteristics of the paper used:
- Plain Paper Insulated Conductors: Utilize plain, uncreased paper, offering basic insulation and straightforward application.
- Thermally Upgraded Paper Insulated Conductors: Feature specially treated paper that can withstand higher temperatures and stress, extending the conductor's lifespan under harsh operating conditions.
Specifications
The specifications for paper insulated copper
- conductors can vary widely depending on their intended application but typically include:
Conductor Material: Copper. - Insulation Material: Paper, often impregnated with mineral oils or synthetic resins to boost dielectric strength and moisture resistance.
- Voltage Rating: These conductors are suited for a broad range of voltages, from medium to high voltage applications.
- Temperature Rating: Designed to operate effectively within a specific temperature range, which is influenced by the paper’s impregnation and treatment.
- Physical Dimensions: The overall diameter and thickness of the conductor are dictated by the required electrical capacity and the voltage level of the application.
Paper insulated copper conductors are preferred in applications demanding high electrical integrity and reliability, combining the excellent conductive properties of copper with the robust insulation provided by impregnated paper.
