Ayegh Haye Electriki Pars

Pei-co is an internationally operating manufacture of power, distribution and special transformers insulating system components on the basis of Transformerboard (Pressboard & Presspaper) and Transformerboard (Laminated Compressed Wood) and Special Insulation papers. Many well-known producers of electro-technical equipments and devices rely on the high quality of our products and get advantage of 35 years experiences and modern technology of our company. Our expertise in electric insulation materials lead the foundation for an internationally reputed enterprise. Insulating Materials and Components of Transformerboard Components and insulating sheets of pressboard are used in oil-immersed power and distribution transformers primarily due to their high purity, mechanical strength and optimal oil-impregnability. Transformerboard is used to subdivide highly stressed oil channels into narrower gaps. The barriers are so arranged to be perpendicular to the electric field lines. Insulation parts are fully impregnated , dimensionally stable , with very favorable dielectric properties and are manufactured to the best quality . Transformerwood in Power Transformers is used close to the ends of windings for clamping rings , Clamping segments, blocks that transfer clamping forces to the windings and terminal holders. They are exposed to not so strong electric fields . The pressboard components , such as angle rings , chimney segments and end leads are chosen so that can adapt themselves with electric field conditions prevailing in the transformer. Especially in highly stressed areas, the dimensional stability and good dielectric features are of great advantage. Special forming and pressing procedures are employed in the manufacturing technique of the pressboard components. Especially in the event of short-circuits the extreme compressibility of Pressboard & laminated Compressed Wood offer the appropiate safety against the enormous mechanical stress in the enormous mechanical stre
