This instrument is a portable, easy-to-operate, high-precision instrument for street light cable maintenance and fault finding.
Advantages and features:
★Simple operation, no need to analyze waveforms.
★Portable, easy for one person to operate.
★Based on DSP digital technology, accurate pinpointing.
★While locating the fault point, it also finds the cable route and burial depth.
★Strong anti-interference, unaffected by branches, conduits, and other factors.
★Hard surfaces above the cable, such as tiles or concrete pavement, do not affect it.
★Various faults of low-voltage cables: open circuit, short circuit, break, ground fault, dead ground, sheath damage, moisture ingress, oxidation, leakage faults, etc.
★Perfect testing without disconnecting fuses.
★No need to introduce high-voltage equipment, safe and easy.
★Transmitter and receiver automatically complete the test, no manual intervention needed.
★When measuring the path, the pointer indicates the cable laying direction; when pinpointing the fault, the pointer indicates the fault point.
Composition
The Street Light Cable Fault Tester consists of three main parts: the RT-2133 Cable Fault Tester main unit, the RT-2132J Cable Fault Locator, and the RT-2132F Cable Path Tracer. The RT-2133 Cable Fault Tester main unit is used to measure the nature of cable faults, the total length of the tested cable, and the approximate location of the 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 location determined by the main unit. For buried cables with unknown routes, the Cable Path Tracer is needed to determine the underground cable route. If the specific route of the underground cable is known, the Cable Path Tracer may not be used. The RT-2133 Cable Fault Tester main unit can be directly connected to a laptop for easy management and operation. The RT-213X complete cable fault testing instrument set can quickly and accurately find fault points in various cables, suitable for factories, mines, metallurgy, petrochemical systems, power plants, airports, railways, and power supply departments. The RT-213X Cable Fault Comprehensive 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 (Main Unit)
Types of cable faults that can be tested:
Various cross-sections of aluminum or copper core power cables, coaxial cables, and other types of cables: flashover cable faults or faults with extremely high resistance; closed cable faults or general high-resistance faults; low-resistance faults, short circuits, or open circuits; cable length and propagation speed of electrical waves in the cable. Specifications and parameters
Voltage level of testable cables: below 35KV; maximum test distance: 15Km; maximum working error: ±3%; operating ambient temperature: -10 to 40℃; operating ambient humidity: 45 to 75%; working power: 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 filter device on the sound channel of the RT-2132F Cable Fault Locator maximally removes interfering noise while enhancing the sound produced 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 listening to changes in underground sound and displaying the distance.
Specifications and parameters
Can synchronously 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 0.1 meters; power supply voltage: 9V; power consumption: 0.2W; operating temperature: -10 to 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 route 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 to 40 ℃; dimensions: 300*250*90; weight: 1.5kg
