Equipment and spare partsBrowse manufacturers Search by manufacturerAnshan Anza Power Switchgear, Dielectric Laminates & Agro Machinery
Anshan Anza Electronic Power Co., Ltd. (brand ANZA / ASANZA, 鞍山安扎电子有限公司) is an established Chinese manufacturing and engineering exporter founded in 2004 in Anshan, Liaoning Province. The company specializes in the design and production of modular low- and medium-voltage switchgear assemblies, electrical drawout connectors, rigid and flexible dielectric insulation materials, agricultural soil preparation implements, and tractor hydraulic powertrain components.
Equipguo provides direct factory procurement, quality assurance, and international logistics for ANZA modular switchgear, medium-voltage ring main units, VS1 vacuum circuit breakers, FR-4/G10 laminates, mica tapes, and agricultural machinery, delivering dependable turnkey equipment packages globally.
Low-voltage switchgear systems including 8PT, MNS, MDmax, Blockset, GCK, and GCS series are engineered for efficient power distribution in high-demand continuous industrial facilities, substations, and utilities. Supporting rated busbar currents up to 6300 A with internal compartmentalization configurations up to Form 4b, these modular assemblies ensure robust arc-fault containment, thermal dissipation, and comprehensive operator safety.
Heavy-duty drawout power contacts including tulip-style clusters and knife-blade connectors provide safe and low-resistance engagement for withdrawable functional units in switchgear lineups. Fabricated from premium electrolytic copper with heavy silver plating (15 to 30 microns), they feature non-magnetic stainless steel spring rings that maintain constant contact pressure through hundreds of racking cycles.
Modular withdrawable drawer units in standard heights (8E/4, 8E/2, 8E, 16E, and 24E) integrate multi-point rotary mechanical interlocks. The mechanism strictly enforces sequence interlocks between Connected, Test, Disconnected, and Removed positions, preventing operator racking errors while the main breaker is closed and blocking door opening during energized operation.
Medium-voltage gas-insulated and solid-insulated switchgear assemblies (12 kV, 24 kV, and 40.5 kV ratings) deliver resilient primary and secondary distribution for municipal utility grids, wind farms, solar plants, and heavy industrial facilities. The 3mm robotic-welded stainless steel enclosure completely encapsulates the three-position disconnector, busbars, and vacuum bottles, securing an IP67 hermetic seal against harsh ambient humidity, dust, and flooding.
Indoor medium-voltage vacuum circuit breakers in the VS1 and ZN63 series serve as prime switching apparatus for withdrawable air-insulated switchgear lineups such as KYN28A-12. Featuring modern alumina ceramic vacuum interrupters paired with high-efficiency spring-stored energy or permanent magnetic actuators, they achieve mechanical endurances exceeding 20,000 operations without component overhaul.
High-performance rigid insulating laminates manufactured by high-pressure thermal lamination utilize electrical-grade E-glass cloth or heavy cotton fabric impregnated with thermosetting epoxy, phenolic, or polyimide resins. Grades including FR-4, G10, G11, 3240, 3025, and 3021 exhibit remarkable dielectric breakdown voltage, minimal water absorption, Class B/F/H thermal endurance, and precise CNC machinability.
The specialized flexible dielectric product line comprises phlogopite and muscovite mica tapes reinforced with E-glass fabric or polymer films, thermal polyimide films (PI), polyester films (PET), and pressboard insulation paper. Mica tapes retain dielectric integrity under direct flame conditions up to 1000 °C, providing vital fire barrier protection for safety cables, marine cabling, and heavy turbo-generator stator windings.
Anshan Anza manufactures a comprehensive lineup of tractor-mounted and trailed agricultural implements including 1L and 1LF moldboard and hydraulic reversible ploughs, 1BQX and 1BJX disc harrows, 9G series rotary mowers, and tractor post-hole diggers. Ground-engaging cutting tools are forged from boron-alloyed and high-carbon wear-resistant steels, heat-treated to ensure exceptional service life across heavy soils.
The replacement tractor components catalog includes high-pressure hydraulic assemblies (gear pumps, double-acting lift cylinders, directional multi-spool control valves, hydrostatic power steering units), along with heavy drivetrain and cooling powertrain parts (clutch pressure plates, crankshafts, water pumps, aluminum and copper radiators) for AZ series, MTZ/Belarus, UMZ, T-40, T-25, and UTB tractors.
Our technical engineers provide comprehensive specification matching for switchgear assemblies, ring main units, vacuum circuit breakers, and drawout contact clusters based on one-line electrical diagrams and project schedules, along with custom precision CNC machining of FR-4 and phenolic insulation boards.
Anshan Anza electrical switchgear, dielectric laminates, and agricultural machinery are successfully deployed across power utility substations, metallurgical plants, mining operations, cable manufacturing factories, and farming enterprises throughout the CIS, Eastern Europe, the Middle East, and Southeast Asia.
Manufacturing workflows are certified in strict conformity with ISO 9001 quality management and ISO 14001 environmental standards. All medium- and low-voltage electrical apparatus undergo rigorous type testing and routine acceptance tests per IEC 61439, IEC 62271, and GOST standards, including dielectric withstand, temperature-rise, and short-time withstand current verifications.
Equipment shipments are fulfilled under standard Incoterms (FOB, CIF, DAP, DDP). We manage the entire international supply chain workflow, including factory inspection, China export customs clearance, multimodal maritime/rail freight, transit cargo insurance, and destination import handling.
