The 220 kV power transformers developed and manufactured by Tian’an Electric adopt the folded-plate oil tank structure used in the 110 kV models, resulting in a more rational product design that facilitates on-site installation and core-exposure inspection. Leveraging the company’s many years of experience in transformer design and manufacturing, the products achieve internationally advanced levels of reliability and performance. Through continuous refinement and improvement, a comprehensive product series has been established, encompassing three-phase dual-winding and three-winding no-load tap-changing transformers, on-load tap-changing transformers, and autotransformers, among others.

As urban distribution networks undergo continuous renovation and expansion, a large number of overhead lines within cities have been replaced by cable lines, and pole-mounted switches have been superseded by switchgear cabinets. The DFT6-12(40.5) outdoor ring main unit is a new type of power supply equipment designed by Tian’an Electric to support 10 kV (35 kV) cable-based power grids. It is widely used at cable connection points in 10 kV (35 kV) systems for the reception and distribution of electrical energy. Each ring main line in the product is equipped with either a load switch or a vacuum circuit breaker, allowing any individual branch circuit to be independently disconnected or reconnected without affecting the other circuits in the ring network. When a combined electrical solution is employed, if a short-circuit fault occurs in a particular branch circuit, the fuse on that circuit will quickly interrupt the faulty circuit and simultaneously actuate the tripping mechanism of the load switch, causing it to open and isolate the faulted circuit. This ensures uninterrupted power supply to the non-faulty branch circuits.
