whay we used silica gel in Transformer

Answer Posted / girish vania

Silicagel is used in transformer to restrict the entry of
moisture particle in side the tank. When the oil is been
heated inside then the warm air goes out from ventilation
plug at the same time fresh air has to enter inside to
fulfill the vacume. This fresh air goes to silicagel
breather where moisture particle is been adopted by
silicagel.

Sir, My doubt on cable sizing calculation, Load:74 KW calculated cable 1 run 50mm2. Now client asking us to reduce cable size by increasing runs. Sir, My question now when my mind strikes with 2 options 1) Divide load 74/2 = 36 and calculate cable for 36+36 making it 2 runs or 2) Simply i can divide 50mm2 /2 ie. 2 runs of 25mm2 Please suggest me sir
