The domestic power transmission and distribution field has witnessed a technological upgrade. The S13-M-30 20-kilovolt-level
power distribution transformer has attracted industry attention due to its innovative composite insulation structure. Based on the traditional
Oil-Immersed Power Transformer, this equipment breaks through the conventional integration of solid insulating materials and self-circulating cooling technology, effectively solving the dual problems of fire separation distance and noise control encountered in the renovation of old community power grids.
It is reported that this transformer takes into account the deep compatibility with intelligent switch cabinets during the design stage. Its low-voltage outlet terminals adopt modular expansion interfaces, which can flexibly connect with
Dry-Type Power Transformers or secondary control systems of oil-immersed equipment. Engineering tests show that in the power distribution rooms that mix dry-type power transformers, its electromagnetic compatibility performance has significantly improved compared to conventional equipment, especially suitable for sensitive power usage scenarios such as hospitals and data centers.
It is worth noting that this product creatively combines the heat dissipation advantages of oil-immersed power transformers with the safety characteristics of dry equipment. Its explosion-proof oil tank adopts a wave-shaped plate three-dimensional heat dissipation structure, combined with the intelligent monitoring module inside the
Switch Cabinet, to achieve real-time linkage and early warning of transformer winding temperature and insulation parameters. Industry experts believe that this "oil-dry dual-mode" design concept provides an expandable and flexible solution for future rural and urban power grid construction.
