galvanic insulation is when two different metal materials are electrically isolated to prevent galvanic corrosion. Galvanic corrosion is similar to the reaction that takes place in an electric battery cell. Two materials, an anode and a cathode, immersed in an electrolyte produce a voltage that causes metal ions from the anode to move to the cathode. This is a desired effect in a battery since it allows electricity to charge and discharge. However, the galvanic reaction causes the anode to gradually corrode and when corrosion is not desirable, the materials must be insulated. For example, when immersed in water, aluminum acts as an anode for chromium, which can cause aluminum parts to corrode when it rains, unless they are insulated. Both of these materials are used in some products, such as automobiles, for structural and ornamental purposes, and corrosion is generally not desired. Therefore they must be galvanically insulated to prevent corrosion.
Completely isolate the electrical circuit - so use some insulation such as PVC to ensure the metals are not in contact - but the above situation should not be allowed in the first place - very poor design indeed.
A galvanic isolator is a device which blocks low voltage DC currents coming on board a boat. The reason why these currents are blocked, they cause corrosion to metal underwater.
Refractory insulation is defined as insulation for extremely high temperatures. The threshold of temperature of insulation for refractory insulation is > 815 Celsius.
The person that invented insulation was John Player. This was the standard type of insulation, and it was invented by him in 1893.

The new leader had a galvanic effect on our morale Reshma Aurangabadkar
The anode is more prone to corrosion in a galvanic cell.
The Galvanic Spa is small instrument (on size of cellular phone) that manufacture by Nu Skin enterprises. The instrument come with 4 heads for the face, scalp and body. The Galvanic know how to smooth wrinkles, treat cellulite and to prevent hair lose. The machine use gentle galvanic currents to refresh and energise the skin.
