SXBP Series Resonant AC Hipot Test System for Pow | RFQ Sourcing Details

The SXBP is a configurable series resonant AC hipot test system intended for AC withstand testing of electrical equipment in substations rated from 10 kV through 500 kV or below.

Listed test objects include XLPE power cables, GIS, power transformers, generators, switchgear, circuit breakers, motors, insulators, bushings, power capacitors and CT/PT equipment. It is described for field, acceptance, preventive and maintenance testing.

The system uses modular reactors that can be arranged to suit different voltage and capacity requirements. Available configurations list a 20–300 Hz test-frequency range and include an AC power source, exciting transformer, reactors and a capacitive voltage divider.

Depending on the selected model, the listed power-source and exciting-transformer ratings range from 5 kW to 30 kW. The also identifies real-time screen display of test data, operating status and procedural steps, computer control, LCD display and printable test results.

Protection functions listed for the system include overcurrent, overvoltage, IPM and discharge protection. The reactors are described as dry-type epoxy-cast units with high mechanical strength, insulation capability and limited temperature rise at rated load.

The equipment is presented as portable for field operation, although package dimensions and gross weight indicate that transport and handling arrangements should be reviewed for the chosen configuration.

Configuration examples include SXBP-27/54/108-108, SXBP-54/108/216-216, SXBP-65/130/260-520, SXBP-45/90/135/180/270-270 and SXBP18/36/54. Published examples cover specific cable lengths and conductor sizes as well as GIS, transformer, circuit-breaker, busbar, insulator and switchgear test duties.

These examples should be treated as configuration references rather than universal capability statements.

Before procurement, the buyer should provide the exact test object, rated voltage, required test voltage, capacitance or cable conductor size and length, desired test duration, available site input supply, test location and applicable acceptance procedure.

Confirm the reactor quantity and connection, total system capacity, divider rating, accessories, control and printing functions, package breakdown, lifting requirements and final factory test documentation.

The available information gives inconsistent warranty terms-one section lists two years, while another states one year-so the warranty period and after-sales scope should be resolved in the purchase contract.

Input-power information should also be confirmed because the listing includes both AC 380 V and 220/380 V single-phase references.
