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 unit undergoes a three-level quality inspection system: raw material entry inspection, in-process patrol inspection, and full project factory testing. Before shipment, every product is subjected to more than 20 strict tests — including power frequency withstand voltage, partial discharge, and mechanical characteristics — with key parameters exceeding national standards by over 10%.
Q
What is the rated capacity range of the transformer in the box-type substation?
The transformer supports a rated capacity range of 100 KVA to 1250 KVA, operating at 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 protection grade does the box-type transformer enclosure meet?
The enclosure of the high-voltage cabinet, transformer, and low-voltage cabinet all meet the IP23 protection standard, providing reliable protection against solid objects and water ingress, ensuring safe operation in various outdoor and semi-outdoor environments.
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 match the architectural style of surrounding buildings. Options such as green fences and artistic paintings are available, allowing the substation to blend seamlessly into the urban landscape.
Q
What type test certifications has the box-type transformer obtained?
The product has passed a comprehensive 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
Does the manufacturer provide technical documentation and on-site training support?
Yes. Every product is delivered with a complete technical file package, including electrical drawings, operation manuals, and maintenance guidelines. On-site operation training and ongoing technical support are also provided to ensure users can safely and correctly operate and maintain the equipment.
