Product Detail

Product Description
The Rockwill Pad-Mounted Transformer is an innovative integrated power distribution solution that combines the transformer body, high-voltage load switch, fuse system and related auxiliary equipment into a single compact unit. Utilizing a fully insulated and sealed design with all major electrical components immersed in insulating oil, this product achieves exceptional space efficiency while maintaining high performance. Supporting both loop and radial network configurations, it offers flexible adaptation to various distribution network requirements, making it particularly suitable for space-constrained installation sites. Our design philosophy integrates safety protection with space optimization, ensuring reliable power supply while significantly reducing initial investment and operational maintenance costs.

Hi everyone, I’m Felix, and I’ve been working in electrical equipment fault repair for 15 years.Over these years, I’ve traveled across factories, substations, and distribution rooms all over the country, troubleshooting and repairing all kinds of electrical equipment. Dry-type transformers are among the most common devices we deal with.Today, a friend asked me:“What does it mean when the low-voltage side of a dry-type transformer has low insulation resistance?”Great

What tests are required for dry-type transformers?
1 Pre - commissioning InspectionAs a front - line tester, before formally commissioning a dry - type transformer, I need to carry out a comprehensive and systematic inspection. First, I conduct a visual inspection of the transformer body and its accessories, carefully checking for mechanical damage or deformation. Then, I check whether the leads of the high - and low - voltage windings are firmly connected and whether the bolt tightening torque meets the standard requirements (usually 40 - 60N&m

What aspects need attention during the installation of dry-type transformers?
1 Pre - installation PreparationAs a front - line installer, I know very well that the preparation work before installing a dry - type transformer must be thorough. First, I will carefully review the design drawings and technical documents, and check one by one the technical parameters such as the model specification, rated capacity, and voltage level of the transformer to ensure they are in full compliance with the design requirements. Then, I will conduct an unpacking inspection of the transfo

What are the causes of dry-type transformers burning out during operation?
What are the causes of dry-type transformers burning out during operation?
1 Fault PhenomenonI am engaged in front - line fault maintenance work, and recently encountered problems with dry - type transformers. Dry - type transformers have a simple structure, are convenient for transportation, and easy for maintenance. They are widely used in power distribution places with relatively high environmental protection requirements. Because of their good fire - resistance, they can be installed in load - center areas to reduce voltage loss and power loss.The property manageme
