 "faq": [
  {
   "q": "What is the rated capacity of the 66 kV Oil-Immersed Pure-Copper Solar PV Power Transformer (40 MVA)?",
   "a": "The standard configuration is rated 40 MVA at 50 / 60 Hz. Other ratings in the same family can be built to order — tell us the load and we will confirm the nearest standard rating."
  },
  {
   "q": "What voltage ratio is available?",
   "a": "The standard unit is 66 kV input to 15 / 20 kV output. Voltage ratio, tapping range and vector group can be adjusted to your network; 50 Hz and 60 Hz designs are available."
  },
  {
   "q": "Which standards and certifications apply?",
   "a": "The product is designed to IEC 60076 / GB. MARS operates an ISO 9001 / 14001 / 45001 certified factory and holds CE (ECM), UDEM, EAC and CQC approvals; every unit is routine-tested before dispatch and type or witnessed tests can be arranged."
