Oil-Immersed Transformer Tank
Product Overview
A specialized enclosure for oil-immersed transformers, serving as the core carrier for internal components (core, windings) and insulating oil. It integrates protection, cooling, and sealing functions, directly affecting the transformer’s insulation performance, heat dissipation efficiency, and operational reliability.
Structural Design:
Welding Process: After assembling the tank edge, corrugated tank wall, and tank bottom, mixed gas automatic shielded welding is used—ensuring high welding quality, tightness, and resistance to oil leakage (critical for avoiding insulating oil contamination and environmental risks).
Cooling Structure: Adopts a corrugated tank wall design; corrugated sheets increase the heat dissipation surface area, enabling natural oil circulation (via convection) to dissipate heat. This design also features smooth oil return, no oil accumulation dead corners, and no easy oil stain buildup, while maintaining an aesthetic appearance.
Cleanliness Control: Targeting the complexity of the tank structure (many welds and dead corners) and strict internal cleanliness requirements (contamination directly impairs transformer electrical performance), advanced equipment such as fully automatic flushing, painting, plastic spraying, shot blasting is used to ensure internal purity.
Advantage
Leak-Proof & Sealing Performance Mixed gas automatic shielded welding ensures a tight tank structure, preventing insulating oil leakage—avoiding environmental hazards (consistent with the “no oil leakage risk” requirement for oil-immersed transformer tanks in the industry).
Efficient Heat Dissipation Corrugated tank wall design enhances heat exchange efficiency with the environment, matching the natural cooling (ONAN) demand of small and medium-sized oil-immersed transformers, and reducing the need for additional cooling devices.
High Cleanliness & Reliability Fully automatic cleaning and surface treatment equipment guarantees strict internal cleanliness, avoiding insulation breakdown caused by impurities and ensuring stable transformer electrical performance.
Durability & Aesthetics Smooth oil flow and no dead corners reduce oil deterioration and internal corrosion; the corrugated structure and uniform welding ensure structural durability and an orderly, aesthetic appearance.
Application
Core Application: Primarily used as a special cooling and protection component for small and medium-sized power transformers, matching scenarios such as:
Industrial power distribution: Supporting small and medium-sized oil-immersed transformers in factories, petrochemical plants, and mining areas, ensuring stable operation in industrial environments.
Urban/rural power grids: Matching distribution transformers in residential areas, commercial complexes, and rural power networks, adapting to outdoor or semi-outdoor installation conditions.
New energy auxiliary: Assisting small and medium-sized transformers in photovoltaic/wind power supporting facilities (e.g., on-site distribution), leveraging its sealing and heat dissipation advantages to cope with outdoor environments.
