Quality assurance: All the products will go through lots of tests carefully before dispatch: Raw   material check, Winding test, Assemble test, Painting check, Nameplate check and routine tests.   2. Competitive production capacity: monthly production more than 1500 sets.   3. Manufactuer's price: Factory direct sale, most competitive price.   1.Technical Data   Instruction                The Transformer is a transformer whose interior is isolated from the air surrounding, so the   transformer oil can not absorb the outer moisture and the oxygen since the change of   transformer's volume could be fixed with the flexibility of corrugated tank structure. Then the aging   speed of insulated material will be decreased. Before running the machine, the work of core   suspension checkup is not necessary. Clients could also be free from the later maintenance and   reparation. The reliability of products is visibly upgraded. Products is designed with PCCAD, the   characters are conformed to IEC 60076 and GB 1094, and passed qualification ISO 9001.         The coil is with high-intensity enameled wires (or paper wrapped wired). Bucket form or cake   form, evenly coiled and installed. Its insulation structure is reasonable, and it has strong anti-   shortcut capacity. All the screws will not become loose after long journey. All sealed parts use   rubber, which could effectively anti-aging by heat, light and electricity, also emote controlled   thermometer and pressure release valves which increase the reliability.    Characteristics   1. No devices like oil tank, and humidity absorber could assure the oil to be insulated from air and the oil could be used for 20 years consecutively without any treatment later    2. High qualified rubber used for the sealing    3. Oil filling in vacuum condition      11kV Series
