VS1 Series High-Voltage Vacuum Circuit Breaker
The VS1 (ZN63A) indoor high-voltage vacuum circuit breaker is switching equipment designed for 12 kV power systems, serving as the control and protection unit for electrical installations in industrial and mining enterprises, power plants, and substations. Owing to the inherent superior performance of vacuum circuit breakers, they are particularly well suited for applications requiring frequent operation at rated current or repeated interruption of short-circuit currents. This circuit breaker complies with the requirements of GB 1984-89 “Alternating-Current High-Voltage Circuit Breakers,” JB 3855-1996 “Indoor AC High-Voltage Vacuum Circuit Breakers, 3.6–40.5 kV,” and DL 403-2000 “Technical Specifications for Ordering High-Voltage Vacuum Circuit Breakers, 10–40.5 kV,” as well as the relevant requirements of IEC 56 (Publication 87).

TANW1 Intelligent Universal Low-Voltage Circuit Breaker
The TANW1 series circuit breaker is suitable for use in low-voltage distribution networks operating at 50Hz, with rated voltages of 400V/690V, and rated current ranges from 630A to 6300A. It can distribute electrical energy and protect lines, transformers, motors, and other equipment from hazards such as overload, short circuit, undervoltage, and grounding faults. It serves as the main switch or an important branch switch in low-voltage distribution systems. Equipped with an intelligent controller, it offers higher protection accuracy, more protection functions, and enhanced communication expansion capabilities compared to traditional circuit breakers. It is widely used in distribution scenarios such as factories, commercial buildings, data centers, and municipal engineering projects

10–35 kV Oil-Immersed Transformers
S13-M Series Three-Phase Oil-Immersed Fully Sealed Distribution Transformer. Unlike conventional oil-immersed transformers, this model eliminates the conservator tank and relies instead on corrugated-fin radiators integrated into the transformer tank for heat dissipation and cooling, while the elastic expansion and contraction of the radiator compensates for changes in oil volume. The product features a compact footprint and an aesthetically pleasing appearance, enabling core-free lifting, maintenance-free operation, and low noise levels.

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.
