China Prefabricated Substation Suppliers | YB-12 Factory for Efficient 10kV Urban Power Distribution Solutions
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?
Every box-type transformer undergoes a rigorous three-level quality inspection system: raw material entry inspection, production process patrol inspection, and full project factory testing. More than 20 strict tests are performed, including power frequency withstand voltage, partial discharge, and mechanical characteristics tests, 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 1250 KVA, making it suitable for a wide variety of commercial, industrial, and urban power distribution applications.
Q
What type test certifications has the box-type transformer obtained?
The product has passed a full range of type tests conducted by national authoritative testing institutions. These include temperature rise tests, short-circuit tolerance verification, protection level tests, and climate environment tests. All test reports are complete and fully traceable.
Q
Can the appearance of the box-type transformer be customized to match the surrounding environment?
Yes. The exterior of the box can be fully custom-designed to incorporate local cultural elements or coordinate with the architectural style of surrounding buildings. Options such as green fences and artistic paintings can be applied, transforming the substation into an integrated part of the urban landscape.
Q
What documentation and support is provided with each box-type transformer?
Each product comes with a complete technical file package that includes 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 of the box-type transformer, and is it suitable for outdoor installation?
The high-voltage electrical cabinet, transformer, and low-voltage electrical cabinet all carry an IP23 shell protection grade. This level of protection guards against solid objects larger than 12.5mm and water spray at an angle up to 60° from vertical, making the unit suitable for both indoor and sheltered outdoor installation environments.
