Basically, the laws and rules of Gravity and Electricity use the exact same equations, so Einstein thought that since you can insulate against electricity, you can insulate against gravity.
I think you may be confused.
In the last half of his life Einstein tried to discover a unified field theory, which could treat electromagnetism, gravity, and the weak and strong nuclear forces, but was unsuccessful. Einstein had problem accepting that relavistic theory was for big stuff and quantum mechanics was for small stuff.
No Grand Unified Theory has been found yet, although multidimensional superstring seems closer than we ever have ever been.
Einstein developed the field theory of gravity that large masses warp spacetime in a way we perceive as gravitational force.
Magnetism, the field phenomenon related to electricity, surrounds any conductor through which electrical current passes. The voltage element of electricity is insulated but the magnetic field exists outside the wire insulation. I am unaware of insulation that works against a magnetic field.
Both feilds follow the inverse square law, but due to the polar difference, magnetic and gravitational feilds have different shapes.
You can counteract a magnetic field with a opposite poled magnetic field, but as there is no pole associated with gravity it would be difficult to counteract a gravity field with an opposite poled field.
