China Suppliers Factory: Landscape Prefabricated Substation 10kV with Greenery Decorative Shell for Urban Distribution Network
Standardized Manufacturing and Quality Assurance System
-
1Full-process standardized operation: From design selection to production manufacturing, strictly following national standards and enterprise standards. All electrical interfaces, mechanical dimensions, and installation holes are standardized to ensure that products from different batches have complete interchangeability.
-
2The three-level quality inspection system: Raw material entry inspection, production process patrol inspection, and full project testing at the factory constitute a complete quality control chain. Before each product leaves the factory, it undergoes more than 20 strict tests such as power frequency withstand voltage, partial discharge, and mechanical characteristics, with key parameters exceeding the national standards by more than 10%.
-
3Comprehensive type test verification: The product has passed a full range of type tests by the national authoritative testing institution, including temperature rise tests, short-circuit tolerance verification, protection level tests, and climate environment tests, and the test reports are complete and traceable.
-
4Comprehensive documentation and training support: Each product is equipped with a complete technical file package, including electrical drawings, operation manuals, maintenance guidelines, etc. We provide on-site operation training and technical support to customers to ensure that users can safely and correctly use and maintain the equipment.
-
5Deep integration with urban planning: The exterior of the box can be custom-designed, incorporating local cultural elements or coordinating with the architectural style of the surrounding buildings. Green fences, artistic paintings, and other methods can be adopted to transform the substation into a part of the urban landscape, completely changing its traditional dull image.

Frequently Asked Questions (FAQ)
Q
What quality inspection process does the box-type transformer go through before leaving the factory?
Each box-type transformer undergoes a rigorous three-level quality inspection system: raw material entry inspection, production process patrol inspection, and full project factory testing. Before shipment, more than 20 strict tests are performed — including power frequency withstand voltage, partial discharge, and mechanical characteristics — with key parameters exceeding national standards by more than 10%.
Q
What is the rated capacity range of the transformer in the box-type substation?
The transformer within the box-type substation supports a rated capacity range of 100 KVA to 1,250 KVA, with a nominal voltage of 10/0.4 KV and a rated frequency of 50 Hz, making it suitable for a wide range of commercial and industrial power distribution applications.
Q
What type test certifications has the box-type transformer obtained?
The product has passed a comprehensive suite of type tests conducted by national authoritative testing institutions. These include temperature rise tests, short-circuit tolerance verification, protection level tests (IP23), and climate environment tests. All test reports are complete and fully traceable.
Q
Can the exterior design of the box-type transformer be customized?
Yes. The exterior of the box can be fully custom-designed to incorporate local cultural elements or to coordinate with the architectural style of surrounding buildings. Options such as green fences and artistic paintings can be applied, transforming the substation into a visually integrated part of the urban landscape.
Q
What technical documentation and support is provided with each unit?
Every box-type transformer is delivered with a complete technical file package, including electrical drawings, operation manuals, and maintenance guidelines. In addition, on-site operation training and ongoing technical support are provided to ensure that users can safely and correctly operate and maintain the equipment.
Q
What is the shell protection grade and noise level of the box-type transformer?
All three compartments — the high-voltage electrical cabinet, transformer, and low-voltage electrical cabinet — are rated at IP23 protection grade. Regarding noise, oil-type transformers operate at below 55 dB, while dry-type transformers maintain a noise level of ≤65 dB, meeting standard environmental requirements for urban and residential area installations.
