ELECTRICALTRANSFORMERS
ELECTRICALTRANSFORMERS
Since 1960, CED has been a leading manufacturer of electrical transformers, offering both custom-designed and standard mass-produced products. The company prioritizes research and innovation, focusing on energy efficiency and reducing environmental impact. CED pioneered the use of aluminium-wound transformers, providing cost savings for clients.
CED ensures high-quality production through the use of tropicalization with oven-cured polyester resin, which enhances resistance to external agents, adhesion, insulation, and heat transfer. Transformers are earthed with low resistance, and class H winding with double-enamelled conductors is used for durability. All products undergo computerized inspection.
Transformers are constructed with concentric coils to minimize magnetic flow dispersion and voltage drop. They feature anticorrosive galvanized metal accessories, multilayer insulation, and a welded magnetic core to reduce vibrations and magnetic reluctance. Innovative core lamination improves magnetic circuit efficiency.

QUALITY POINT BY POINT Our transformers are tropicalized using oven-cured polyester resin. This procedure results in: • resistance to external agents such as damp and dust; • better winding adhesion; • elimination of vibrations; • better insulation; • better heat transfer to the environment. On request, the transformer can be supplied with spring-loaded connection terminals. This choice results in: • faster cabling times; • greater safety; • greater vibration resistance; • less maintenance. Our transformers are earthed using the fixing bracket welded to the magnetic core of the transformer. The...

DESIGN AND CONSTRUCTION We use innovative core lamination: we have developed core laminates with revolutionary materials and forms. This innovation enables us to: • educe the magnetic gap r • mprove the magnetic circuit i • mprove permeability and reduce dispersion i • educe magnetizing current. r Our transformers have a welded magnetic core. Single-phase transformers with power up to 1000 VA are built by welding the magnetic core. This results in: • elimination of vibrations and resonance; • considerable reduction of the magnetic gap, and thus reduced magnetic reluctance and magnetizing current....
