Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Transformers And Substation Equipment. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
The SGXZ is a variable-frequency series resonant test system intended for AC withstand-voltage testing of high-voltage capacitive equipment. Listed test objects include XLPE cables rated from 10 kV to 500 kV, transformers, hydro generators, GIS, GIL, busbars, SF6 switches, insulators, and CT/PT equipment.
The stated operating-frequency range is 30–300 Hz, with automatic and manual operating modes. The modular system is described as comprising a variable-frequency control power supply, excitation transformer, resonant reactor or reactors, and capacitive voltage divider.
A compensation capacitor is available as an optional component. Resonant reactors may be configured as dry-type epoxy-cast or oil-immersed units. The system provides over-current, over-voltage, and flash-over protection and produces a stated pure sine-wave output.
Available maximum test-voltage configurations are listed as 100 kV, 200 kV, 300 kV, or higher. This equipment is positioned for laboratory and field testing, including preventive-maintenance, commissioning, and acceptance-test programs.
Because the required system configuration depends on the test object's capacitance, rated voltage, test voltage, and test duration, buyers should request an engineered configuration rather than selecting solely by maximum voltage.
Before procurement, confirm the exact test object and voltage class, required withstand voltage and duration, estimated capacitance, reactor arrangement, total system capacity, input-power configuration, duty cycle, included accessories, and applicable test procedure.
Also verify whether the proposed reactor construction, divider rating, cable set, control functions, transport cases, and compensation capacitor meet the project scope.
The source information lists both 220 V and 380 V input options but contains ambiguous phase and tolerance wording, so the final input voltage, phase, frequency, and permissible variation should be documented in the technical offer.
Package dimensions and weights should likewise be confirmed for the selected configuration because listed dimensional data is not fully consistent.
