High-Quality Energy-Efficient 10KVA~63000KVA/3KV~220KV Oil-immersed Power Transformer
Buchholz Relay: Detects internal faults.
Oil: Serves as the primary insulation and cooling medium
An oil-immersed transformer is a common power equipment that performs critical tasks such as voltage conversion and power distribution in electrical grids. It is widely used in urban/rural power grid upgrades, industrial/mining applications, combined transformers, and prefabricated substations.
Operates on electromagnetic induction, converting voltage via winding turns ratio. Heat generated during energy transfer is dissipated through oil circulation, which also serves as insulation between live parts.
Performance Features
• Near-circular core cross-section improves three-phase balance and lowers harmonic distortion.
• Sealed construction protects insulation from environmental factors.

Operational Parameters
● Temperature Limits
Top oil temperature ≤ 90°C (85°C recommended for longevity). Alarm triggers at 80°C.
● Overload Capacity
Permits 1.1–1.2× rated current during emergencies. Monitor load/temperature post-alarm; reduce load if necessary.
