I'm looking OpAmp which could be powered from dual power supply greater than + - 36V. Current transformer provides 36,9V. And LM358 on a single supply could work up to 36V. I'm looking something what could be work on dual supply up to 40V. Any suggestions? Thank you
If it's a conventional current transformer and has an internal burden then applying an extra external burden resistor will lower the output voltage and give you more options on the choice of op-amp. Alternatively just use a potential divider to reduce the voltage to a more acceptable level.

Don't bother trying to find a +/- 40V op amp, just add a high voltage output stage to your LM358.
Having said that I did find this: The LM143 which runs up to +/- 40V
Have a look at the LTC6090, which accomodates a supply voltage of up to 140V (+/- 70V) with rail to rail output swing and generally reasonable specifications all around:
