power transformers (66-132 kV class) operate at higher voltage and capacity for regional supply.<\/div>\n<\/details><details class=\"subian-faq__item\">\n<summary class=\"subian-faq__question\">Can you build single-phase pole-mounted transformers?<\/summary>\n<div class=\"subian-faq__answer\">Yes &#8211;

ONAF with fans is available for higher overload capacity.<\/div>\n<\/details><details class=\"subian-faq__item\">\n<summary class=\"subian-faq__question\">What is the minimum order quantity?<\/summary>\n<div class=\"subian-faq__answer\">Single units are available; container volumes receive the best factory pricing and models can be mixed.<\/div>\n<\/details><details class=\"subian-faq__item\">\n<summary class=\"subian-faq__question\">Why is transformer oil used in distribution transformers?<\/summary>\n<div class=\"subian-faq__answer\">Transformer oil provides both insulation and cooling, allowing higher capacity in a compact tank. It also carries moisture away from the windings and helps preserve the paper insulation over the transformer&#8217;s service life.<\/div>\n<\/details><details class=\"subian-faq__item\"><summary class=\"subian-faq__question\">How is Oil Immersed Distribution Transformer tested before shipment?<\/summary><div class=\"subian-faq__answer\">Routine tests to IEC 60076-1: winding resistance, ratio, impedance, no-load loss, load loss, insulation resistance and induced voltage. A witnessed factory acceptance test can be booked at drawing approval, with the buyer or a third-party inspector present.<\/div><\/details><details class=\"subian-faq__item\"><summary class=\"subian-faq__question\">What documents come with Oil Immersed Distribution Transformer?<\/summary><div class=\"subian-faq__answer\">The routine test certificate, a nameplate photograph, the packing list, the warranty statement and the HS code.
