Nantong Zhihe Electric Co., Ltd. has secured an order for 98 custom power transformer oil tanks, with a planned average production time of approximately 25 days per tank. The order covers non-standard tank designs manufactured according to the customer's drawings and technical requirements.
For transformer manufacturers, a large order for custom tanks brings two closely connected priorities: meeting the required specifications and keeping production aligned with the transformer assembly schedule. This project brings both into focus.
Custom Manufacturing for Non-Standard Designs
Unlike a standard tank model, a custom transformer oil tank requires production planning around its specific structure. Tank dimensions, reinforcement arrangements, flange locations and mounting interfaces all need to follow the approved drawings.
For this 98-unit order, our work centres on turning those drawings into finished tanks that are ready for the customer's subsequent assembly process. Careful coordination between fabrication, welding, leak testing and coating is essential to maintaining consistency across the order.
An Average Production Time of 25 Days per Tank
The planned average production time for this project is approximately 25 days per tank. This figure applies to individual tank production; batch completion and shipment dates are arranged according to the overall project schedule.
A clear production schedule helps the customer coordinate tank availability with other transformer components and assembly activities. For custom projects, the schedule must also account for structural complexity, inspection requirements and the specified surface finish.
At ZHIHE Electric, production time is assessed against the actual drawings and order requirements so that customers can plan around a project-specific schedule.
Robotic Welding and Leak Testing Before Coating
Our transformer tank manufacturing combines robotic welding with manual welding for areas that require access or flexibility beyond the robotic process. This combination supports the fabrication of different tank structures while keeping attention on weld quality.
Every tank undergoes leak testing before coating. Testing at this stage allows any leakage points to be identified and addressed before the protective finish is applied.
Surface preparation and coating then follow the agreed project requirements. Alongside the tank structure and welds, these steps are an important part of preparing the finished product for its intended operating environment.
Supporting Transformer Manufacturers with Custom Tank Supply
The 98-unit order adds to ZHIHE Electric's experience in supplying power transformer oil tanks for projects requiring custom structures and coordinated production schedules.
Based in Hai'an, Nantong, China, we manufacture transformer oil tanks, transformer radiators and prefabricated substation enclosures according to customers' drawings. Our tank range includes power transformer tanks, corrugated distribution transformer tanks, pad-mounted transformer tanks and single-phase pole-mounted transformer tanks.
