Product Description

Underground Cable Fault Tester

Darui Electric recommends for you:

According to the treatment solutions for underground line faults, there are three methods in total: the analytical judgment method, using a simple grounding fault tester to test faults, and using an intelligent cable fault tester to test faults, which is very convenient and can accurately locate within one meter. There is no need to repeatedly dig up the road surface to search, saving a lot of manpower, material resources, and financial resources. It reduces maintenance costs.

Product Composition

The underground cable fault tester consists of three main parts: the RT-2133 cable fault tester host, the RT-2132J cable fault locator, and the RT-2132F cable path tracer. The RT-2133 cable fault tester host is used to measure the nature of cable faults, the total length of the tested cable, and the approximate position of the cable fault point from the test end. The RT-2132J cable fault locator is used to determine the precise location of the cable fault point based on the approximate position determined by the cable fault tester host. For buried cables with unknown routing, a cable path tracer is needed to determine the direction of the underground cable. If the specific routing of the underground cable is known, the cable path tracer may not be used. The RT-2133 cable fault tester host can be directly connected to a laptop computer for convenient management and operation. The RT-213X complete set of cable fault testers can quickly and accurately find fault points in various cables when used together, suitable for factories, mines, metallurgy, petrochemical systems, power plants, airports, railways, and power supply departments. The RT-213X comprehensive cable fault tester is widely used for detecting low resistance, short circuit, open circuit, and various high resistance faults in aluminum-core and copper-core power cables of various cross-sections below 35KV, high-frequency coaxial cables, and local telephone cables. It is an essential device for ensuring safe power supply and a powerful assistant for cable production and maintenance workers.

(1), Cable Fault Tester

Types of cable faults that can be tested:

For aluminum-core or copper-core power cables of various cross-sections, coaxial cables, and other types of cables: flashover cable faults or faults with extremely high resistance; enclosed cable faults or general high resistance faults; low resistance faults, short circuits, or open circuits in cables; cable length and the propagation speed of electrical waves in the cable. Specifications and parameters

Voltage level of testable cables: below 35KV; maximum test distance: 15Km; working limit error: ±3%; operating ambient temperature: -10～40℃; operating ambient humidity: 45～75 %; working power supply: rechargeable battery; power consumption: 30W; dimensions: 230*140*270 (mm3); weight: 2 kg;

(2), Cable Fault Locator

The RT-2132J cable fault locator is equipped with first-class integrated circuits and amplifiers. The filtering device on the sound channel of the RT-2132F cable fault locator maximizes the removal of interfering noise while enhancing the sound generated by the arc. The liquid crystal display can simultaneously show sound pulses and magnetic pulses as well as the distance from the fault point to the probe test point. This allows for joint judgment of the fault point by monitoring changes in underground sound and displayed distance.

Specifications and parameters

Can simultaneously receive the sound waves and electromagnetic waves generated during fault point discharge and display the distance from the probe to the fault point; display distance: maximum 22.6 meters, minimum distance 0.1 meters; power supply voltage: 9V; power consumption: 0.2W; operating temperature: -10-40℃; dimensions: locator: 180*80*70; probe: Ф85*90; weight: 1.5Kg (including probe);

(3), RT-2132F Cable Path Tracer

The RT-2132F cable path tracer is an instrument for checking the routing and burial depth of underground cables. When the cable route is unknown, it is used to find the path and depth of underground cables.

Specifications and parameters:

Test signal: sine wave, frequency 15KHz, 1KHz; output power: > 30W; output impedance: >8Ω; power supply voltage: AC 220V± 10﹪, 50Hz±1﹪; operating ambient temperature: -10 - 40 ℃; dimensions: 300*250*90; weight: 1.5kg
