PCB in Transformer Oil (Simplified for Beginners)

2024-10-19

PCB (Polychlorinated Biphenyl) is a man-made chemical once widely used in transformer oil because of its excellent electrical insulation properties and low flammability. It was popular as an insulating fluid because it helped transformers work safely. However, PCB is now banned in many countries after it was discovered to have harmful effects on the environment and human health. Modern transformer oils made from petroleum do not contain PCB.

Why is PCB Dangerous? PCB is a harmful substance that can cause cancer and other serious health problems. It builds up in body fat, leading to diseases that affect the brain, skin, and internal organs. It can also harm the nervous, reproductive, and immune systems.

How Does PCB Affect the Environment? PCB does not easily break down in nature. It doesn’t dissolve well in water but mixes easily with fats and organic solvents, which makes it dangerous because it accumulates in the fat of living organisms and becomes more concentrated as it moves up the food chain.

PCB’s Properties PCB has some very stable physical and chemical properties:

It’s resistant to acids, bases, and oxidation.
It doesn’t corrode metals.
It provides excellent electrical insulation.
It can withstand high temperatures (1,000°C to 1,400°C before fully breaking down).
Most forms of PCB do not burn.
Because of these properties, PCB was used not only in transformers but also in many industrial products, including resins, rubber, adhesives, coatings, and even as additives in dyes and ceramics. However, due to its dangerous effects, its use is now highly restricted.
