Aluminum Paper-Insulated Continuously Transposed Conductor (Aluminum CTC)

PRODUCT OVERVIEW

Aluminum Paper-Insulated Continuously Transposed Conductor (Aluminum CTC) is designed for transformer winding applications requiring reliable electrical performance, efficient conductor arrangement, and optimized winding space utilization.

The conductor consists of multiple rectangular aluminum strands continuously transposed and individually insulated with electrical insulation paper. This construction helps reduce eddy-current losses within the winding conductor and provides flexibility for transformer winding design.

Aluminum CTC can be customized according to transformer design requirements, including strand dimensions, strand count, insulation thickness, and transposition geometry.

FAQ

What is Aluminum CTC?

Aluminum CTC is a continuously transposed conductor made from multiple rectangular aluminum strands, commonly used in transformer winding applications.

What is the main advantage of aluminum CTC?

Its main advantage is reduced conductor weight compared with an equivalent copper conductor by volume, subject to the electrical design requirements. Aluminum generally has lower electrical conductivity than copper, so conductor dimensions must be designed accordingly.

Can the strand count and dimensions be customized?

Yes. Strand count, individual strand dimensions, insulation thickness, and overall configuration can be specified according to the customer's transformer design and confirmed manufacturing capabilities.

Is paper-insulated aluminum CTC suitable for oil-immersed transformers?

It can be used in compatible oil-immersed transformer designs, provided that the aluminum conductor, insulation paper, and complete insulation system meet the required electrical, thermal, and mechanical specifications.

How can customers request a quotation?

Please provide the required strand count, individual strand dimensions, insulation specification, quantity, and applicable technical requirements for evaluation.
