1. Product Overview
The SH15‑M amorphous alloy distribution transformer is a fully sealed oil-immersed power distribution transformer optimized for medium and low voltage power grid operation. Different from traditional silicon steel sheet transformers, this product adopts high-performance amorphous alloy strip as the core magnetic conduction material, which fundamentally reduces no-load loss and no-load current during equipment operation. It is a mature energy-saving and consumption-reducing power transformation equipment widely used in domestic and foreign power distribution systems.
This series of transformers features compact overall structure, fully enclosed box body design and reliable sealing performance. The whole machine avoids oil leakage and external dust moisture intrusion, adapting to long-term continuous operation in various complex outdoor and indoor environments. Compared with conventional S9 and S11 series transformers, it has obvious advantages in energy saving, stability and service life, and can effectively reduce the long-term operation and maintenance cost of power grids for users.

3. Product Core Features
3.1 Ultra-low Energy Consumption, Significant Energy-saving Effect
The amorphous alloy core has extremely low magnetic conductivity loss and hysteresis loss. The no-load loss of SH15‑M transformer is far lower than that of traditional silicon steel transformers, with a reduction of about 75%-80% compared with S9 series products. The no-load current is also greatly reduced, which can effectively reduce the idle power consumption of the transformer during standby operation. For power grid operation scenarios with long-term standby and low-load operation, it can save a large amount of electric energy every year and bring obvious economic benefits to users.
3.2 Stable Operation and Strong Anti-interference Ability
The product adopts a three-phase five-limb core structure and pure copper foil winding design, which effectively optimizes the magnetic circuit structure, reduces magnetic leakage and voltage drop. The overall mechanical strength of the winding is high, with excellent short-circuit resistance and overload capacity. The equipment has low temperature rise during operation, slow insulation aging speed, and can maintain stable power supply quality for a long time even in peak load and voltage fluctuation environments.
3.3 Fully Sealed Structure, Low Maintenance
The whole machine adopts an integrated fully sealed box body and bolted sealing structure for the box cover. The internal transformer oil is isolated from the external air, avoiding oil oxidation, moisture absorption and deterioration. There is basically no oil leakage risk in the whole life cycle. It abandons the traditional oil conservator design, reduces external vulnerable parts, realizes long-term maintenance-free operation, and greatly reduces daily operation pressure for users.
3.4 Low Noise and Environmentally Friendly
The unique core processing technology and overall shock absorption structure effectively reduce electromagnetic noise and operating vibration. The operating noise is far lower than the national standard limit, which will not cause noise pollution to the surrounding environment. At the same time, low energy consumption reduces power generation energy consumption and carbon emission, complying with green power grid construction and energy conservation and emission reduction policies.
3.5 Compact Structure and Wide Adaptability
The optimized structural design reduces the overall height and volume of the transformer, saving installation space. The equipment has strong corrosion resistance and weather resistance, and can adapt to high temperature, low temperature, humid and other harsh outdoor environments, without frequent environmental adaptation maintenance.
4. Application Scenarios
Relying on energy-saving, stable and low-maintenance advantages, SH15‑M amorphous alloy distribution transformers are widely used in various medium and low voltage power distribution scenarios, covering civil, commercial, industrial and new energy fields:
4.1 Urban and Rural Residential Power Grids
Suitable for community power distribution stations, rural power grid renovation and residential centralized power supply scenarios. It adapts to the characteristics of intermittent load and long standby time of residential power consumption, effectively reducing the idle loss of power grid equipment and improving the economy of regional power grid operation.
4.2 Commercial and Public Infrastructure
Widely used in shopping malls, hospitals, schools, office buildings, airports, railway stations and other public places. The low-noise and stable operation characteristics avoid impact on public working and living environment, and the high reliability ensures continuous and uninterrupted power supply for public facilities.
4.3 Industrial Production Sites
Applicable to factory workshops, industrial parks, mining enterprises and other industrial power supply scenarios. Its strong overload resistance and short-circuit resistance can cope with industrial load fluctuation and sudden load impact, ensuring stable power supply for production equipment and reducing production shutdown risks caused by power equipment failure.
4.4 New Energy Power Generation Projects
Matched with photovoltaic power stations, wind power stations and distributed new energy power generation systems. It can adapt to the unstable power output characteristics of new energy, stabilize grid voltage, reduce power loss in power transmission and distribution process, and improve the utilization rate of new energy power generation.
4.5 Other Special Scenarios
It can also be used for power supply of scenic spots, highway facilities, communication base stations and other outdoor unattended scenarios. The low-maintenance design greatly reduces the frequency of on-site inspection and maintenance, which is suitable for remote and inconvenient maintenance operation scenarios.
5. Product Maintenance and After-sales Service
5.1 Daily Maintenance Guidelines
The SH15‑M fully sealed transformer has low daily maintenance requirements, and conventional inspection can ensure long-term stable operation of the equipment. It is recommended to carry out routine visual inspection every 3-6 months, focusing on checking whether the box body has oil leakage, whether the casing is damaged, and whether the wiring terminal has abnormal heating and discoloration.
Carry out professional comprehensive detection every 12-18 months, including transformer oil dielectric strength test, insulation resistance detection and operating noise monitoring. For equipment operating in high temperature, high humidity or dusty harsh environments, the detection cycle can be appropriately shortened. Since the whole machine is fully sealed, there is no need to frequently replace or supplement transformer oil in daily use, avoiding tedious maintenance work.
During operation, avoid long-term overload operation beyond the rated parameter range to prevent accelerated aging of internal insulation materials. In thunderstorm seasons, regularly check the performance of supporting lightning protection devices to ensure the safety of equipment operation.
5.2 Fault Handling Instructions
In case of abnormal noise, sudden temperature rise, tripping and other abnormal conditions of the equipment during operation, the user should first cut off the power supply for shutdown inspection, and do not disassemble the equipment privately to avoid secondary damage and safety accidents. Record the abnormal phenomenon and operating parameters in time, and feed back to the after-sales technical team. Professional technicians will provide remote guidance or on-site maintenance services according to the fault situation.
5.3 After-sales Service Commitment
