Okken Low-Voltage Switchgear
Okken is a modular low-voltage switchgear designed for power distribution and motor control in large-scale facilities across industries, the tertiary sector, and infrastructure projects.
Its inherent characteristics ensure a high level of reliability, full adaptability to application requirements, and a high degree of scalability.
The user-friendly design simplifies the on-site installation, operation, and maintenance of the distribution cabinet.
The innovative patented design meets stringent schedule and power continuity requirements: it can be modified on-site and reconfigured while energized*.
A single-structure frame and busbar system ensures optimal operating conditions regardless of whether the wiring is front-mounted or rear-mounted.
Depending on the required level of operation and maintenance (IS) for different electrical equipment, various types of feeder units can be installed in the same cabinet row or even within the same cabinet. For example, feeder circuits and motor control circuits can also be mixed and installed together.
Okken is a distribution cabinet that complies with international standards and can meet the local practices of most users.
1. Unique busbar configuration (rectangular arrangement of A, B, C, and N poles) reduces busbar copper consumption and enhances the product’s rated short-time withstand current.
2. A handling base is designed at the bottom of the cabinet for convenient on-site installation;
3. Busbar connection technology without punching, facilitating busbar installation, connection, and maintenance;
4. Several practical functional unit connection configurations have been designed to meet a wide range of user requirements;
5. Functional units rated at 630 A and below widely employ a dual-clamp connection system, ensuring maintenance-free operation and long service life for the vertical busbar.
6. The product features a high-density internal partitioning design, enhancing its safety;
7. The product has successfully passed the 100 kA internal arc fault test, electromagnetic compatibility test, seismic resistance test at intensity 9, and high-altitude test at 5,000 m, thereby ensuring its safety.
8. The product is designed with detachable cross beams and supports for convenient on-site equipment installation.
