Product catalog summary

Product Overview
The UHV-500 Cable Fault Detector by Wuhan UHV Power Technology Co., Ltd. is designed to ensure the smooth operation of wired communication and power transmission by detecting and rectifying cable faults promptly. It employs advanced electronic technologies and computer techniques to test various cable faults, including high-resistance flashover faults, grounding issues, short circuits, and cable breaks. The device is suitable for power and communication cables of various types and voltage levels.

Part 1: Cable Fault Distance Testing

Comprehensive Functionality: Utilizes low-voltage pulse and high-voltage flashover methods for safe, rapid, and accurate fault testing.
High Testing Accuracy: Features a high-speed data sampling technology with a 100MHz A/D sampling rate, offering a reading resolution of 1m.
High Level of Intelligence: Automatically displays test results as waveforms and data on a large LCD screen with a full Chinese menu display.
Storage and Recall Function: Non-volatile components ensure data retention after power-off.
Dual-Trace Display Function: Allows comparison of faulty and normal waveforms for enhanced diagnosis.
Waveform Expansion Ratio Function: Enables precise testing by changing the waveform scale.
Adjustable Propagation Speed: Can be adjusted according to different cables.
Portable Design: Compact and powered by a rechargeable battery.

Parameters: Suitable for testing power cables (1KV～35KV), telephone cables, FM communication cables, coaxial cables, and metal overhead lines. Maximum testing distance is 15Km (up to 100km for open lines).

Part Two: Cable Route Locator
The locator consists of a transmitter, receiver, audio probe, and headphones. It features high receiver sensitivity, low static drift, easy operation, strong anti-interference capability, and is powered by a built-in lithium battery.

Part Three: Locating the Fault Point
The principle involves using high voltage to discharge the fault point, converting the vibration sound into an electrical signal, and amplifying it for detection through headphones. The process includes measuring the distance to the fault point and using a locator for precise location.

Pulse Capacitor
Features a fully sealed metal casing, suitable for inrush current generators and other equipment. Specifications include a rated voltage of 1KV ~ 15KV and a nominal capacitance of 0.1μF ~ 8μF.

YDJ(Z)-3kVA/50kV Oil Type AC Test Transformer
Characterized by reliable quality, good stability, and the use of new insulation materials. It has a large voltage margin and small size.

Wuhan UHV Power Technology Co.,Ltd. The instrument consists of four parts: a transmitter, a receiver, an audio probe, and headphones, as shown in the figure. • High receiver sensitivity • Easy operation • Strong anti-interference capability • Built-in lithium battery powered and comes with a charger Test Principle We know that when a cable fault point is broken down by high voltage, the discharge will produce a loud vibration sound. Since the cable is buried very deep, it is not easy for the human ear to hear. At this time, the weak vibration signal is converted into an electrical signal by a...
