There are various transformer components in the compact transformer substation, which play an important role in ensuring the warranty time and producing electricity. The compact transformer substations have severe requirements for fire protection. First of all, fire-resistant and flame-retardant materials are selected for the enclosure. We know that steel plates, aluminum alloys and other materials have fire-resistant and flame-retardant properties, but the nylon foam, fibers, etc. filled in their centers are often not fire-resistant, even flammable materials.

After several flame-retardant experiments, scientific research staff found that glass fiber, asbestos net and other constituent materials worked well and met the planning requirements, and the problem of fire-resistant and flame-retardant enclosure was solved. The enclosure function of the compact transformer substation will also directly affect its fire resistance and resistance function. Now we have found that there are some weak links in the fire protection of the cabinets of some substations.
