TRANSFORMER BUSHINGS UP TO 40.5KV

Specifications Small volume, light weight, reasonable structure, appearance beautiful, reliable sealing and electric field uniform distribution

  Product Description   1. Summary   Oil-impregnated paper condenser bushings are used to extract voltage and carry current for the transformer, at the same time, they are used to be the ground insulation of the current-carrying part and mechanical back-up.    2.Operation conditions 1. Ambient temperature:-45℃-40℃ 2. Sea level elevation: not over 1000m, if the sea level elevation of the using site is over 1000m, it should be talked over with the manufacturing company. 3. Common type is suitable for light filthy area; antifouling type is suitable for heavy filthy area. 4. Installation method: vertical or leaning angle is not over 30℃. 5. Test voltage of the bushings sees the table below.
