Metal Clad Switchgear
Metal Clad Switchgear
As a professional metal clad switchgear manufacturer, Juhongkai provides reliable, safe, and durable metal-enclosed switchgear for medium and high voltage power systems. Our solutions are ideal for substations, industrial plants, and commercial facilities worldwide.
Metal-clad switchgear is a robust, compartmentalized medium-voltage electrical assembly (2.4kV-38kV) featuring separate, grounded metal enclosures for circuit breakers, busbars, and control components, providing enhanced safety, reliability, and maintenance access for power distribution in industrial, commercial, and utility settings. Key features include segregated compartments, strong steel construction, and integration of components like breakers (vacuum, SF6) and protective relays for centralized control, protection, and isolation of power systems.
Compartmentalization: Each major component (breaker, bus, control, cable) is in its own metal-enclosed section, increasing safety by isolating faults and allowing maintenance on one part without affecting others.
Construction: Made of thick steel (2-4mm), offering durability and protection.
Components: Includes circuit breakers (vacuum, SF6), potential/current transformers (PTs/CTs), busbars, protective relays, and control devices.
Voltage Ratings: Typically 4.76 kV to 38 kV.
Enhanced Safety: Segregated compartments and grounded metal barriers protect personnel from live parts and arc-flash events.
Reliability: High-quality construction and internal separation minimize failures and allow for targeted maintenance.
Customization: Can be configured with specific breakers (spring/magnetic), relays, and arrangements (single/double bus) for various applications.
Industrial Facilities: Petrochemical plants, refineries, manufacturing.
Utilities: Power generation, transmission, and distribution substations.
Commercial: Large buildings, data centers.
Metal-clad switchgear acts as the nerve center for medium-voltage power, housing all protective and switching devices in a compact, secure metal structure, allowing operators to safely control, protect, and distribute electricity from generators, motors, and feeder circuits.
1. Industry-Leading R&D Capability: The first domestic enterprise to complete R&D, network access testing, and batch supply of *standardized & customized metal clad switchgear*. Covering 12kV/24kV/40.5kV, meeting medium-voltage power grid, industrial, and infrastructure demands.
2. CNAS-Accredited In-House Lab: Lab certified by CNAS (China National Accreditation Service for Conformity Assessment) – conducts full performance tests for metal clad switchgear: insulation strength test, mechanical operation life test (≥10,000 times), short-circuit withstand test, and dust-proof/water-proof test.
3. Smart Manufacturing & Quality Control : Equipped with a "smart quality control brain" and automated production lines (e.g., precision sheet metal processing, armor cabinet assembly), monitoring the entire manufacturing process to ensure consistent batch quality.
4. Mature Batch Supply Capacity: Stable supply chain for core components (circuit breakers, isolating switches), supporting urgent project timelines (e.g., 25-day delivery for KYN28A-12 batch orders).
"There is always a ring main unit suitable for you!" Juhonkia continues to introduce new products in the field of ring main units. The ring main unit series products achieve full coverage of voltage levels and different insulation media products. It is the first domestic enterprise to simultaneously complete the R&D, manufacturing, network access testing and batch supply of standardized and customized SF6 gas insulation, solid insulation, environmentally friendly gas insulation, atmospheric air insulated ring main switchgear primary and secondary integrated ring main switchgear.
