8PT, MNS and Blockset modular low-voltage switchgear
Low-voltage switchgear systems including 8PT, MNS, MDmax, Blockset, GCK, and GCS series are engineered for heavy-duty power distribution across substations, industrial plants, and utility infrastructure.
Supporting rated busbar currents up to 6300 A with internal compartmentalization up to Form 4b, these assemblies deliver superior arc-fault containment, thermal dissipation, and operator safety. Main copper busbars undergo tin or silver plating, handling peak withstand currents up to 220 kA.
Both withdrawable and fixed functional units feature robust mechanical interlocks to prevent incorrect switching operations. Flexible top or bottom cable entry configurations simplify site installation and ongoing maintenance for heavy power feeders up to 630 mm².
Drawout power connectors and tulip contact clusters
Heavy-duty drawout power contacts including tulip-style clusters and knife-blade connectors provide low-resistance engagement for withdrawable functional units in switchgear lineups.
Fabricated from premium electrolytic copper with heavy silver plating (15 to 30 microns), they integrate non-magnetic stainless steel spring rings that maintain constant contact pressure through hundreds of racking cycles.
Continuous current ratings span from 100 A to 630 A with minimal contact voltage drop and robust electrodynamic ride-through capability during short-circuit faults. Flame-retardant polyamide insulating blocks ensure long-term dielectric performance.
8E withdrawable drawers and rotary interlock mechanisms
Modular withdrawable drawer units in standard heights (8E/4, 8E/2, 8E, 16E, and 24E) integrate multi-point rotary mechanical operating and interlocking mechanisms.
The mechanism strictly enforces sequence interlocks between Connected, Test, Disconnected, and Removed positions, preventing operator racking errors while the main circuit breaker is closed.
Drawer cassettes feature integrated auxiliary telemetry microswitches for remote SCADA indication and precision guided rails that eliminate binding during routine plant maintenance.
MXGN gas-insulated ring main units (GIS) and 10-35 kV switchgear
Compact medium-voltage gas-insulated ring main units (SF6 GIS) of the MXGN series rated for 10 kV, 20 kV, and 35 kV service are designed for power utilities, industrial substations, wind farms, and photovoltaic facilities.
All live medium-voltage components, three-position load break switches, and earthing switches are hermetically enclosed within a 3 mm laser-welded stainless steel tank with IP67 protection.
The sealed GIS design requires zero primary maintenance over a 30-year operational lifecycle, withstands extreme humidity and dust, and features SF6 gas density monitors and digital micro-processor protection relays.
VS1 indoor vacuum circuit breakers and interrupters
VS1 series three-pole indoor vacuum circuit breakers rated for 12 kV and 24 kV systems with continuous currents up to 4000 A and breaking currents up to 50 kA are supplied in fixed and withdrawable truck executions for KYN28A switchgear cubicles.
High-purity vacuum interrupter bottles with CuCr copper-chromium contact material provide fast arc extinction with minimal electrical contact erosion.
The integrated spring operating mechanism delivers mechanical endurance rated for 10,000 operations (Class M2), allowing motor-driven or manual emergency charging with auxiliary trip coils.
FR-4, G10 epoxy glass cloth laminates and 3025 phenolic sheet
Rigid dielectric sheets and fabricated tubes are manufactured by impregnating alkali-free woven glass cloth with thermosetting epoxy resin systems under high-pressure thermal lamination.
FR-4 sheets deliver certified UL94 V-0 flame retardancy, exceptional dielectric breakdown strength (up to 20 kV/mm) under humid and dry conditions, and superior flexural mechanical strength across thermal class B (130 °C) and F (155 °C).
We provide custom CNC routering, precision drilling, and profile milling per client CAD engineering drawings for partition barriers and busbar supports.
Fire-resistant mica tapes, PI films and electrical pressboard
Our extensive portfolio of flexible electrical dielectric materials encompasses phlogopite and muscovite mica tapes reinforced with glass cloth or polyester backing, high-temperature polyimide (PI) films, PET films, and electrical pressboard.
Fire-barrier mica tapes maintain critical dielectric integrity under direct flame exposure up to 1000 °C, guaranteeing continuous survival of fire-rated power and emergency control cables for 90 to 180 minutes.
Polyimide films retain mechanical elasticity across an extreme thermal envelope from -269 °C to +400 °C, widely deployed in traction motor slot liners.
Agricultural tillage implements, 1L/1LF ploughs and tractor spares
Anshan Anza agricultural implement division manufactures heavy-duty tractor-mounted share and reversible hydraulic ploughs (1L and 1LF series), heavy tandem disc harrows (1BQX), rotary disc mowers (9G), and post-hole diggers.
Tillage wearing parts are forged from heat-treated boron steel for maximum abrasion resistance in dense rocky and clay soils.
The replacement tractor components line features hydraulic gear pumps (up to 25 MPa), lift cylinders, heavy-duty clutch kits, crankshafts, and engine cooling radiators for diverse tractor horsepower classes.
Technical engineering sizing and project configuration
Our technical application engineers review electrical single-line diagrams, engineering specifications, and project load schedules. We configure compliant low-voltage switchgear lineups, matching withdrawable drawer units, heavy-duty tulip contact clusters, and copper busbar dimensions. For dielectric FR-4 and phenolic materials, we provide custom CNC profile routing, drilling, and machining according to client CAD drawings.
Manufacturing quality standards and turnkey logistics
All equipment is exported directly from the Anshan Anza manufacturing facility under standard Incoterms (FOB, CIF, DAP, DDP). Systems undergo comprehensive factory routine testing compliant with IEC 61439, IEC 62271, and ISO 9001 certifications. We manage export documentation, multimodal transit insurance, and global container freight.
