- Description
- Technical Specifications
-
This compact ring main unit encloses all live parts within an IP67-rated stainless steel enclosure. The entire switchgear is unaffected by external environmental conditions, ensuring operational reliability and personal safety, while achieving maintenance-free operation. By selecting expandable busbars, any combination can be realized to achieve full modularity. The expandable busbars are fully insulated and shielded, ensuring high reliability and safety. The Aggremax series switches also offer factory-automated solutions, forming the concept of intelligent switching and minimizing on-site installation and commissioning workload.
Aggremax is available in standard configurations of 2, 3, 4, 5, or 6 ways, with additional equipment added according to customer requirements. Due to its combination of full and half modules and its own expandability, Aggremax offers exceptional flexibility.
Product Features:
Switches are mutually interlocked, switch position indicators are clear, and come standard with live indication functions to ensure safety.
Reliable: Pressure relief channels are designed to prevent arc faults, tested with a 20kA internal arc fault test.
Stable: Programmed design, standardized process control, and modular combinations ensure stable quality.
Fully insulated, fully enclosed, maintenance-free:
All high-voltage live parts are completely enclosed within the SF6 tank, with a protection rating of IP67. The entire switchgear is unaffected by external environmental conditions, allowing arbitrary combinations and unlimited expansion.
Can be used in separated compartments or achieve multi-way units sharing a compartment, freely combining various module units to meet different customer needs.
Modules can be flexibly expanded on-site, easily building various medium-voltage substations with different requirements. Modular design allows free expansion and combination.
Wide applicability:
User distribution rooms, outdoor switching stations, box-type substations, wind power generation, hydroelectric power generation.
Basements, damp and condensation conditions, plateau climates, low temperatures, large temperature differences.
Intelligent:
Can provide intelligent distribution network systems with supporting functions such as protection, remote control, monitoring, and fault handling.
