OVERVIEW

CTC Conductor Application

A Continuously Transposed Conductor (CTC) with paper insulation refers to a specific type of electrical conductor used in high-voltage applications.

Power Transformers CTCs are often used in transformer windings where they offer improved current distribution, reduced losses, and enhanced thermal performance.
Power Cables CTCs can be used in power cables for transmitting electricity over long distances with minimal losses.
High-Frequency Applications CTCs are suitable for high-frequency applications such as inductors and transformers used in radio frequency (RF) systems, telecommunications, and power electronics.
Induction Heating Coils CTCs are utilized in induction heating coils where uniform current distribution is crucial for efficient and consistent heating of metals.
Railway Electrification CTCs are employed in overhead catenary systems for railway electrification
Aerospace and Defense CTCs are used in various aerospace and defense applications, including radar systems, avionics, and satellite communication systems

CORE FEATURES

A Continuously Transposed Conductor (CTC) is a type of electrical conductor that is commonly used in applications where high flexibility and resistance to mechanical stress are required.

This transposition helps to mitigate the effects of circulating currents and eddy currents that can occur in the conductor, reducing losses and improving the overall efficiency of the electrical system.

CTCs are often insulated using high-quality electrical-grade paper.

Eddy currents, which are induced circulating currents within conductors, can lead to significant energy losses in electrical systems.

The insulation helps to dissipate heat and provides a barrier against high temperatures that can be generated due to the high electrical loads.

The continuous arrangement and paper insulation contribute to the mechanical strength and stability of the conductor.

CTCs with paper insulation are commonly used in high-voltage applications such as power transformers and reactors.

The design of CTCs with paper insulation is aimed at improving the longevity and reliability of electrical components.

The design of CTCs with paper insulation can be customized to meet specific requirements of different applications.

Product Packaging

Reel Packaging: For larger quantities of CTC cables, manufacturers might package them on reels. Reels provide a neat and organized way to store and transport longer lengths of cable;

Cardboard or Plastic Reels: Reels used for packaging cables are commonly made from materials like cardboard or plastic.

Palletization: When shipping larger quantities, CTC cable packages may be palletized for efficient transport.

What is CTC winding used for?

CTC conductors are frequently used in the windings of power transformers. Power transformers are critical components in electrical distribution systems, converting voltage levels for transmission and distribution.

Why choose the CTC Wire?

CTC conductors help mitigate eddy current losses, which are losses that occur due to the circulating currents induced by the varying magnetic fields within the transformer.
