YHLDY type street lamp cable fault tester

1、 Product Introduction:

YHLDY type street lamp cable fault testerUsed for buried low-voltage cables and streetlight cables; Test for locating the fault point of poor insulation between the metal conductor of the optical cable and the ground. For dead grounding faults in buried high-voltage cables that cannot be located by discharge acoustic measurement method; Street light cable; Railway signal line; Low voltage power and lighting buried cables form a circuit with metal conductors and the earth; Cable protective layers and cable shielding layers with metal conductors are applicable. Its main function is not only to locate and test points with poor ground insulation, but also to detect cable routing and the depth of cable burial.

2、 Product Name:

Street lamp cable fault tester, cable fault detector, high-voltage cable fault tester, buried cable fault tester

3、 Product features:

This instrument uses a quartz crystal oscillator and a medium to large scale integrated circuit. Its characteristics are high receiving sensitivity, small static drift, strong anti-interference ability, stable operation, and high accuracy. Due to the use of small nickel cadmium batteries for power supply, the instrument has the advantages of small size, light weight, low power consumption, and easy portability, making it particularly suitable for field operations
