Import Bdv Tester — Buy in wholesale FOB from Supplier in China

The BDV tester from Chongqing Zhongneng Oil Purifier Manufacture Co., Ltd. is an instrument for measuring the breakdown voltage of insulating oils used in transformers, switchgear, and other high-voltage electrical equipment. The unit incorporates a single-plate integrated circuit for control and measurement, with a digital display for reading results. The supplier is based in Chongqing's Jiulong Industry Park, operating as an imported supplier within the harbour trust tier. The tester is designed for portability and on-site use in industrial maintenance environments.

Breakdown voltage testing of transformer oil follows standards such as IEC 60156, ASTM D877, and ASTM D1816, which specify electrode geometry, gap settings, and voltage ramp rates. Typical test voltages for new mineral oil range from 30 kV to 70 kV depending on oil grade and moisture content. The Iij-ii model designation suggests a portable benchtop unit, though exact output voltage range, measurement accuracy in kilovolts, and resolution are not stated in the source. Standard BDV testers offer electrode gap adjustment from 2.0 mm to 2.5 mm, with some units accommodating 1.0 mm for ASTM D1816. The oil test cell is typically a mug-type vessel with either spherical or mushroom-shaped electrodes in brass or stainless steel.

End-users include power generation utilities, transformer maintenance contractors, industrial facilities with large electrical assets, and oil testing laboratories. The instrument is used for predictive maintenance, commissioning new equipment, and monitoring oil degradation over time. Chongqing Zhongneng Oil Purifier Manufacture Co., Ltd. is located in a heavy-industry zone of Chongqing, a municipality in southwestern China with established electrical equipment manufacturing. Buyers should confirm the exact model specifications, calibration certificate traceability, warranty terms, and whether the unit operates on 220V/50Hz Chinese mains or includes 110V/60Hz compatibility for export markets.

Chongqing Zhongneng Oil Purifier Manufacture Co., Ltd. is located at No.3 Torch Avenue, Jiulong Industry Park, Chongqing 400039, China, in an industrial zone of this southwestern municipality. The company is classified as an imported supplier on the platform with harbour trust tier status, and no response rate or average response time is recorded. This limited interaction history means buyers must conduct independent due diligence before relying on the supplier for critical test equipment procurement.

The listing positions the company as a manufacturer of oil purifiers and associated testing equipment, specifically the BDV tester described here. No verified information is available regarding factory floor area, number of employees, annual turnover, export experience, ISO certification status, or client references. The Jiulong Industry Park location suggests industrial rather than commercial premises, but buyers should request factory audit reports, business licence copies, and quality management system certificates directly. The supplier's specialisation in oil purifiers may indicate in-house electronics assembly capability, or the BDV unit may be sourced from a partner; clarify the manufacturing scope and control over the test instrument's calibration and servicing.
