NON - ENCAPSULATED DRY - TYPE TRANSFORMER SG(B)10 - 100 - 4000/10

The insulation class is H(189℃) and large insulation design allowance.Design of SG(B)10 Series for dry type transformer is H level thermal insulation class and the main insulating material is C-class American DuPont NOMEX paper (heat accessible to 220℃). The transformer in use will not aid combustion, flame retardant, explode and release harmful gas.

The transformer core uses high-permeability and high-quality cold-rolled silicon steel sheets with a special design. The operating noise is far lower than national standards. It can be recycled after the life without no pollution.Transformers insulated by the dense paper products of NOMEX work satisfactorily in the wettest environments.

When the coil is processed as a whole, the sealing level of the wire and the mechanical degree of the coil are strengthened again by multiple vacuum pressure dipping varnishes and at the same time the transformer's resistance to mold and moisture is improved.
