An Electric pole is an example for cantilever end type of column. i.e.fixed at one end and loaded at other ends. As per IS 456:2000 for this type of end condition eff L=2L.

When the upper end of a pole connected with wire than pole assumed hinged at one end so effective length will 0.8 * l.

I am correct or wrong?

Wire doesn't support to pole by hinge, so plole will be act as cantilever column.
So it's effective length will be 2l.
