33kV Pole Mounted Transformer

The 33kV Pole Mounted Transformer launched by SARAH Electrical is designed specifically for the decentralized distribution needs of urban and rural residential overhead distribution networks, and is also suitable for light load and diversified power consumption scenarios (such as rural small hydropower grid connection, small industrial and commercial power supply, etc.).

As the core equipment of the power distribution system, it is optimized for the "end power supply" of the power grid (such as overhead lines in towns, streets, and rural villages), supporting two structural designs: conventional and fully self-protection. The iron core can be made of coiled iron core (C.R.G.O material) or amorphous alloy iron core, balancing energy efficiency and cost, and meeting the reliability and energy-saving needs of power supply under different working conditions.

Features

1. The 1.33kV Pole Mounted Transformer strictly follows international/domestic standards such as ANSI, IEC, GB, SANS, etc., and has passed the testing of China's national quality supervision and inspection center (insulators, fuses, lightning arresters, and line equipment), achieving both performance and safety standards.

2. From transportation, installation to daily operation, humanized design has been carried out: the lifting structure is stable, the wiring terminals are protected against electric shock, the nameplate parameters are clear, and the risk of manual errors is reduced.

3. Cylindrical (or square) shell design, uniform heat dissipation and visually simple; The internal winding and iron core layout are compact, reducing electromagnetic interference and improving power supply stability.

4. The single-phase column mounted transformer adopts a fully sealed structure to isolate air, moisture, and dust, avoiding insulation oil (or dry-type structure) from being affected by moisture and aging, greatly extending the service life of the equipment, especially suitable for humid and dusty outdoor environments.

5. Optimization of winding process and iron core material to reduce no-load and load losses, and improve the overall energy efficiency of the power grid; Strong impact resistance during short circuit and overload, ensuring stable operation of the 'end power grid'.

6. The overload capacity design is reasonable, and stable power supply can still be achieved during short-term overloads (such as peak electricity consumption in rural areas during summer and winter); Under normal operating conditions, the energy efficiency ratio is high, and long-term operation saves electricity costs.

Applicable scenarios

The "last mile" power supply for townships, streets, and rural villages is improved by replacing old oil immersed/dry-type transformers with 33kV Pole Mounted Transformers.

Independent power supply for small processing plants, rural cooperatives, rural homestays, and other scenarios, or grid connected distribution of distributed energy sources such as photovoltaics and small hydropower.

The fully sealed structure ensures long-term operation in outdoor environments that are humid, dusty, and have large temperature differences (such as coastal areas in the south and dusty areas in the north).

Standard

Voltage range: 6kV -11kV (input), suitable for common voltage levels in urban and rural distribution networks.

The fully sealed column mounted transformer supports multiple capacities (such as 25kVA, 37.5kVA, etc., depending on the model) to meet different load requirements.

Core type: coiled core (C.R.G.O) or amorphous alloy core (low loss, suitable for energy efficiency priority scenarios).

Protection level: Fully sealed design, shell protection level ≥ IP54 (depending on model), dustproof and waterproof.

Execution standard: GB1094.1 - 2013, GB1094.2 - 2013, GB1094.3 - 2003, GB1094.5 - 2008, GB/T 1094.10 - 2003, JB/T 10317 - 2002, IEEE Std C57.12.00TM - 2010, ANSI C57.12.00, C57.12.20, IEC60076, SANS 780. Wait.
