and electrical testing services for all types of power users. It is
a well-known brand of electrical testing equipment in China.
The six major categories of products independently developed and
produced by the company are mainly used in the handover test,
preventive test, condition maintenance and intelligent substation
detection of various voltage levels of power equipment in all links
of the power system from power generation, transmission and
distribution to distribution, factory inspection and annual
inspection of primary equipment. Specifically divided into: high
voltage/ultra-high voltage/ultra-high voltage AC and DC test
equipment series, mobile power test intelligent integrated system,
transmission and transformation test instrument, power
metering/standard series, SF6 gas/oil test series, battery test
series. All products have passed the inspection or type test of the
"National Power Industry Electrical Equipment Quality Inspection
and Testing Center"; and obtained the calibration certificate of
the "National High Voltage Metering Station".
