oil transformer(S9)(S11) |
|
Product Name:
|
S9 |
|
Description:
|
Features:
1) The edges of the oil tank are welded with stainless steel with Haihong's design patent The edges reinforce the mechanical strength,rust prevention, magnet prevention and polished appearance
2) The tank is equipped with Haihong's patented accessory YWJ oil level gauge, which is of reasonable design, direct display, and thoroughly solves the problems such as oil level, working temperature, pressure relief and oil conservation.
3) The oil tank and clampingpiece are rust-removed, acid-cleaned and paint-coated for several times. Using the imported special antirust paint prevents desquamation and depigmentation. The clamping screws are of stainless steel and will never get rusty
4) The stainless steel welded edges are rust preventive, as well as aging preventive for the gaskets
5) The gaskets are made by the 41st Research Institute of the Fourth Academy of China Airspace Corp. The gaskets are of drip molding with the surface specially treated to ensure hermetization and reliability
6) The magnetic core consists of imported oriental crystal laminations with a very low loss factor. The spacer blocks are made of electrical insulating laminated compressed wood to ensure no distortion or crack but excellent mechanical strength
7) The transformer is of hermetically construction, which insolates the oil from the atmosphere and therefore slows down the aging of the oil
8) Compared to S9-M series transformer, S11-M has an average no-load loss reduced by 30%, no-load current reduced by 60% and noise level reduced by 5-10 dB |
