Unit-type AC metal ring network switchgear

Product Introduction

The unit-type AC metal ring network switchgear is a medium-voltage power distribution equipment with a modular structure, using high-quality steel as the cabinet material and adopting a unitized combination design, integrating core components such as load switches, fuses, and busbars internally. Suitable for 10kV-35kV AC three-phase 50Hz ring network power supply systems and terminal power distribution links, it is widely used in urban distribution networks, industrial parks, and high-rise building power distribution systems, undertaking line on-off control, fault isolation, and protection functions. Compliant with GB/T 11022, IEC 62271 and other standards, it has high integration and operational flexibility.

Product Features

Compact structure: Unitized modules (60%-70% of traditional volume, fit tight spaces) with independent packaging for easy assembly/expansion; Safe and reliable: IP3X/IP4X enclosure (blocks foreign objects/contact) and mechanical interlocks (avoids misoperation); Ring network adaptation: Dual/multiple lines for flexible ring networks (better continuity), load switches with fuses for short-circuit protection; Environmental adaptability: Weather-resistant, sealed for -25℃~+40℃, stable in harsh environments with low maintenance; Smart optional: High-end versions with sensors/communication for remote monitoring and automation docking, enabling unattended operation.

Product Classification

By switch type：Load switch unit (for conventional on-off and isolation); load switch-fuse combination unit (adding short-circuit protection function, suitable for transformer circuits).​ By outgoing line mode：Cable outgoing line unit (connecting underground cable networks); busbar outgoing line unit (supporting multi-cabinet parallel expansion to build large-scale ring network systems).
