In the industrial electrical enclosure sector, static load capacity is one of the key indicators of structural reliability.
In scenarios involving high-density equipment installation and long-term full-load operation, whether an Enclosure possesses stable, verifiable static load capacity directly determines the safety margin for system operation. Based on industry-standard engineering references (e.g., Rittal VX25/TS8 with a rated static load of 1500kg), Saipwell conducted systematic static load testing on the KT Series 16-fold assembly cabinets. Under controlled conditions, these cabinets successfully validated stable load-bearing capacity up to 1800kg.
Why Choose Rittal as the Benchmark for Load Capacity?
In the industrial enclosure industry, benchmarking against Rittal is not a brand comparison, but a reference system for engineering capability.
The 1500kg static load capacity of Rittal’s VX25 / TS8 series represents a widely recognized high-load standard within the industry.
Therefore, conducting test validations under identical load parameters effectively determines whether saipwell’s KT modular enclosures possess the capability to enter the same engineering application range.
This benchmarking focuses on one single core parameter only: Static Load Capacity
Unique Mortise-and-Tenon Modular Structure: All-Welded Frame vs High-Strength Assembly
In the realm of high-load industrial enclosures, fully welded structures have traditionally been regarded as the standard solution for structural stability.
Represented by systems like Rittal VX25 / TS8, these cabinets emphasize overall frame rigidity and standardized expansion capabilities, delivering proven reliability in fixed installation environments.
The Saipwell KT 16 Folded Assembly Cabinet, however, pursues a different structural path. Its core objective is not whether the frame is welded, but how equivalent load-bearing performance can be achieved within a modular assembled structure.
To accomplish this, the KT cabinet adopts several key design elements:
16-fold high-strength frame profiles
Multi-fold cross-section design significantly increases effective load-bearing surfaces.
Mortise-and-tenon assembly structure
Form stable mechanical interlocking relationships at critical load-bearing nodes
Saipwell’s engineering objective is to maintain structural strength while optimizing transportation volume, logistics cost, and global delivery efficiency.
The KT 16-fold modular cabinet has passed 1800kg static load testing, engineering-proven that:
A Systematically engineered and fully validated modular assembly structure can also meet the structural requirements of high-load industrial applications.

Static Load Performance: Modular Structures Can Remain Stable Long-Term
Static load testing evaluates an enclosure’s ability to remain structurally stable under long-term full load, without displacement or vibration.
The KT 16-fold modular enclosure was tested under the following conditions:
- High-density equipment installation
- Long-term full-load operation
- Multiple mounting rails and accessory combinations

Test results:
- Rated static load: 1500 kg
- Actual tested stable load capacity: 1800 kg

Against the industry background where VX25 / TS8 enclosures are rated static load capacity at 1500 kg, these results clearly demonstrate:
Modular assembly ≠ low structural strength
Dynamic Load Capacity: The Real World Is More Than the Control Room
If static load capacity determines whether an enclosure can “stand firmly,” dynamic load performance determines whether it remains reliable during transportation, handling, vibration, and installation.

During dynamic load design and testing, the KT 16-fold cabinet references relevant methods and criteria applied to VX25 / TS8 systems (1500 kg class), while closely reflecting real-world conditions. Key focus areas include:
- Transportation vibration simulation
Continuous vibration and transient impact during road and sea transport are simulated to verify long-distance shipment stability. - Coordinated structural load transfer
The assembled structure behaves as a continuous load-bearing system rather than a collection of independent components. - Door and mounting system stability
Under dynamic loading, doors, mounting rails, and internal installation systems remain secure, with no loosening, displacement, or instability.
Passing dynamic load validation confirms that from factory release through transportation to on-site installation, the KT enclosure maintains structural integrity and installation accuracy—a key advantage for global and export-oriented projects.
Dynamic Load Limit Testing: Engineering Safety Requires Margin

High-standard industrial enclosures must not only meet ‘usage requirements’ but also clearly address two questions:
- Where lies the structural safety margin?
- How does the system respond under extreme conditions?
Saipwell conducted dynamic load limit testing on the KT 16-fold enclosure to:
- Validate the overall structure’s performance under abnormal dynamic loads
- Evaluate the synergy between frame profiles and connection systems
- Reserve sufficient safety margin for real engineering applications
The goal is not to pursue impressive numbers, but to reduce unpredictable risks in real-world projects.
Not a Replacement for VX25 / TS8, but an Alternative Solution

The KT 16-fold modular enclosure is not designed to replicate or replace VX25 / TS8.
Instead, it provides a superior solution in the following scenarios:
- Overseas projects / export-oriented engineering
- High load requirements with logistics cost sensitivity
- Fast deployment and modular integration environments
In these applications, load capacity is not a selling point—it is a baseline requirement.
Structure Defines the Upper Limit, Testing Builds Trust
A truly professional enclosure system is not one that merely looks strong on drawings, but one that remains reliable under static conditions, dynamic movement, and even extreme loads.
Through verified structural design and comprehensive testing, the Saipwell KT 16-fold modular cabinet delivers a more efficient and reliable enclosure solution for global engineering projects.
