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.
What else can I help you with?
How can you prevent galvanic corrosion between 304 stainless steel piping and galvanized saddle tap fittings?
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.
What is galvanic isolation transformer?
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.
What is refractory insulation?
Refractory insulation is defined as insulation for extremely high temperatures. The threshold of temperature of insulation for refractory insulation is > 815 Celsius.
Who invented insulation?
The person that invented insulation was John Player. This was the standard type of insulation, and it was invented by him in 1893.
