Product Description

Product Description

With the full deployment of the urban network transformation, many power supply bureaus, construction parties, and even design units encountered 110kV XLPE cables for the first time. Due to time constraints and insufficient experience, many cables failed to pass the withstand voltage test (10kV/ 1min). At present, most of the outer sheath is made of HDPE sheath material, which has passed the DC 25kV/5min withstand voltage test in the factory, and the leakage current is as low as tens of μA. Therefore, most of the defects after laying are caused by external force damage during laying, including soil filling and cover. Defects after operation usually include termite bites; water in the grounding box; deterioration of the original defect; moisture penetration of the bifurcated part of the grounding wire reduces the insulation resistance, etc., sometimes because the cable is buried too deep or the surrounding conditions are complicated, so It is very difficult to locate, and some defects cannot be resolved after many years, leaving hidden dangers to the operation.



The output voltage of the XHHD523 high-voltage cable sheath fault locator is 10KV and below, which fully meets the Chinese national standard GB50150-2006 cable outer sheath withstand voltage test regulations, including the cable outer sheath handover test and preventive test suitable for cross-interconnect systems And the fault location of the outer sheath of the cable. Quickly and accurately find hidden dangers of 10kv-500kv single-core and three-core high-voltage and ultra-high voltage cable outer sheath grounding faults and large leakage currents. At the same time, it can perform 5kv-10kv on high-density polyethylene and polyvinyl chloride cable outer sheaths, 1 The minute DC withstand voltage test is a special instrument necessary for the maintenance of cable equipment of 10kv-500kv single-core and three-core high-voltage and ultra-high voltage cable operation units, ultra-high voltage cable engineering companies, and various power transmission and transformation engineering companies.

Working principle

1. positioning function
The 220VAC power supply input from the power grid is converted into a high-power special signal required for identification by full wave rectification. This signal is added to the unpositioned cable through the connection line. The cable fault can be accurately fixed by measuring "step voltage method" or "current method".

2.  withstand pressure function
Switch the function key to the voltage withstand function, you can output 0-10kV voltage, and perform voltage withstand test on the cable.
