    2, Factory Area and Equipment

    Pearl Electric covers a factory area of 100,000 square meters, with more than 70,000 square meters of
    up‐to‐date workshop building.
    The workshops are equipped with more than 600 units of modern manufacturing equipment,
    advanced in China and abroad, such as the fully‐automatic vacuum resin‐casting equipment imported from
    Germany HÜBERS company, the automatic slitting lines for silicon steel sheet manufacturing, 600mm
    automatic transverse shear line for transformer core manufacturing, 500t electro‐hydraulic servo and
    numeric‐control bending machine, corrugated tank manufacturing line, foil‐type winding machine,
    lamination and turning platform for large‐size transformer core manufacturing, large‐scale transformer
    assembly platform, vapor‐phase drying plant and etc.. The complete set of transformer testing equipment
    is equipped in the test center, including the shielded measurement room for local partial discharge and
    noise test. Pearl Electric has the capability to carry out all the type tests and routine tests (except the
    short‐circuit test) within the test center, thus greatly satisfying various test requirements for transformer
