112.5 kVA Three Phase Distribution Transformer Basic Features
Compared with dry-type transformers, oil-immersed transformers have more advantages in heat dissipation efficiency and overload capacity. Dry-type transformers rely on air convection for heat dissipation and require larger installation space; while oil-immersed transformers benefit from the much higher heat exchange efficiency of oil than air, allowing large-capacity design and a more compact size. However, 112.5 kVA Three Phase Distribution Transformer require regular maintenance of oil quality, while dry-type transformers are more suitable for indoor scenarios with high fire protection requirements because there is no oil leakage risk. Both have their own advantages. It is only a difference in technical routes, and the choice mainly depends on the actual project cost, efficiency and safety.

112.5 kVA Three Phase Distribution Transformer Application
Global grid voltage standards vary, which brings serious challenges to equipment export and cross-border operation.
There are obvious differences in voltage levels and power frequency standards among power grids in different countries. CHBEB has been deeply engaged in transformer production for many years, and our distribution transformers can meet the voltage demands of mainstream global markets: from 480V to 380V American standard transformers, to 660V/690V to 380V/400V photovoltaic power generation applications, and then to 415V to 380V export solutions for Australia and parts of Southeast Asia. All of these reflect CHBEB’s engineering wisdom of “providing solutions for complex global power grids.” The 112.5 kVA Distribution Transformer is especially suitable for the upgrading and renovation needs of internal distribution systems in some industrial plants and large commercial facilities in North America.
Core Structure and Optional Accessories of 112.5 kVA Three Phase Distribution Transformer
You can select the following accessories as needed to customize the 11 kV / 0.4 kV, 112.5 kVA oil-immersed distribution transformer and improve equipment performance and adaptability:
Core Material
- Silicon steel sheet core: high energy efficiency and low iron loss. Stable energy efficiency and mature technology, it is the mainstream choice for conventional distribution scenarios.
- Amorphous alloy core: extremely low iron loss and excellent energy-saving effect. Suitable for distribution scenarios with long annual operating time and low load rate, with outstanding full life-cycle economic benefits.
Oil Tank and Tank Cover
- Stainless steel oil tank and tank cover: stronger durability and excellent anti-corrosion capability.
Extended Creepage Distance Bushing
- Large creepage distance bushing: suitable for heavily polluted areas and coastal areas, improving insulation performance.
Arrester Bracket
- Arrester mounting bracket: protects against lightning impulse and operating overvoltage.
CSP Integrated Protection Component
- High-voltage fuse, secondary-side circuit breaker, indicator light, external surge suppressor: comprehensive protection against surge current, short circuit and overload faults.
Cooling System Upgrade
- Forced air cooling (ONAF): improves heat dissipation capacity and overall transformer operating efficiency.
- Oil pump + fan combination: forces insulating oil circulation through the oil pump and works with fans to strengthen the cooling effect, meeting the needs of heavy-load working conditions.
Voltage Regulation and Other Accessories
- Tap changer: on-load tap changer / no-load tap changer — realizes voltage regulation and adapts to load fluctuation scenarios.
- Breather: equipped with color-changing silica gel desiccant to prevent moisture from entering the equipment, avoid moisture deterioration of insulating oil, and extend the service life of oil quality.
- Lockable operating switch: improves operation safety and prevents misoperation by non-professional personnel.
- Moving rollers: convenient for equipment transportation and on-site installation.
