YB Preinstalled Compact Substation

High-Quality Casing, 3-Day Deployment, and Built for Your Project

The YB Preinstalled Compact Substation is Weisho Electric’s modular, all-in-one power solution designed for rapid grid connection. It integrates the MV switchgear, power transformer, and LV distribution units into a single enclosure made with a thickened cold-rolled steel casing forged through an integrated molding process. We don't just offer a piece of equipment; we provide a pre-tested, plug-and-play system that can be installed and powered on-site within 1-3 days. With its superior craftsmanship and durable performance, our YB substation is the ideal choice for factories, schools, residential communities, and transportation stations.

Material & Manufacturing Advantages

High-Quality Casing: The casing is made from high-quality, thickened cold-rolled steel plate. Manufactured through an integrated molding process, the strengthened material ensures exceptional structural stability and durability.
Electrostatic Powder Coating: The exterior undergoes an electrostatic powder coating process, forming a durable anti-corrosion layer that is highly heat-resistant and anti-aging, withstanding severe weather and sun exposure.
Precision Craftsmanship: We strictly follow engineering blueprints for all grinding and drilling operations, ensuring every dimension is highly precise with a low defect rate for a perfect fit.
Agile Chassis Design: The chassis uses an industry-standard size with high-hardness, flexible casters. This design allows for easy and precise on-site movement and positioning, making installation simple and safe.

Customer Success Case

Project: Solar Farm Grid Connection for RWE Renewables, Germany

The Challenge: The customer needed a substation that could be deployed quickly and operate reliably in a remote outdoor environment to match the pace of the solar farm’s construction.

Weisho’s Solution: We provided a customized YB preinstalled substation. The unit underwent a series of rigorous vibration and performance tests to ensure reliability during transport and on-site installation.

The Result: The RWE team reported that our solution was the fastest grid connection they had ever used. Our substation saved them weeks of on-site installation time, and its sturdy casing successfully passed all their environmental tests, ensuring the smooth progression of the entire project.

Frequently Asked Questions (FAQ)

Q: What are the core advantages of your YB substation over a traditional substation?

A: Our YB substation is a highly integrated, prefabricated solution that saves up to 70% of the footprint compared to a traditional substation. Its modular design also shortens on-site installation time from weeks to just 1-3 days.

Q: Can your product be used in harsh environments, like a -40°C cold region?

A: Yes, it can. Our standard product operates reliably from -25°C to +45°C. For extreme cold, we offer a custom version with an anti-condensation heater and HVAC system to ensure reliable operation in sub-zero temperatures.

Q: How do you ensure the product’s safety during transport?

A: We use professional reinforced packaging, and the chassis is designed for stability during transport. This minimizes the risk of damage, ensuring the unit is fully functional upon arrival and reducing on-site installation failures.
