China Landscape Prefabricated Substation Suppliers - Efficient 10kV Urban Distribution Network Factory 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 voltage levels does the box-type transformer support?
The box-type transformer supports a high-voltage side of 10KV and a low-voltage side of 0.4KV, making it suitable for standard urban and industrial power distribution networks. The rated capacity ranges from 100KVA to 1250KVA to meet varying load demands.
Q
What quality tests does each unit undergo before leaving the factory?
Every unit undergoes more than 20 strict factory tests, including power frequency withstand voltage, partial discharge detection, and mechanical characteristic verification. Key performance parameters are required to exceed national standards by at least 10%, and all test reports are fully documented and traceable.
Q
What is the shell protection grade of the box-type transformer?
The high-voltage cabinet, transformer, and low-voltage cabinet all carry an IP23 protection rating, providing reliable protection against solid objects and water ingress, making the unit suitable for outdoor and semi-outdoor installation environments.
Q
Can the exterior appearance of the box-type transformer be customized?
Yes. The exterior casing can be fully custom-designed to incorporate local cultural elements or match the architectural style of surrounding buildings. Options include green fences, artistic surface paintings, and other aesthetic treatments to integrate the substation seamlessly into the urban landscape.
Q
What technical documentation and support is provided with each unit?
Each unit comes with a complete technical file package that includes 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.
Q
What type tests has the product passed and are the reports available?
The product has passed a full range of type tests conducted by nationally authorized testing institutions, covering temperature rise tests, short-circuit tolerance verification, protection level tests, and climate environment tests. All test reports are complete, standardized, and fully traceable upon request.
