Cable And Line Testing Instrument

The RDCD-Ⅲ Cable Fault Testing System is the result of years of continuous improvement and innovation by our company. Applying modern power electronics technology, the product is a leading cable fault testing instrument at home and abroad. It is mainly used for distance measurement, path finding and positioning of main insulation fault points of power cables with voltage levels of 35kV and below.

It can also measure low-resistance, short-circuit, open-circuit break faults, as well as high-resistance leakage and high-resistance flashover faults of high-frequency coaxial cables, local telephone cables, street lamp cables and buried wires with various cross-sections. The system consists of three units: the RDCD-Ⅲ/RA52 Trolley-type Cable Fault Pre-locator, the RDCD-Ⅲ/R30 Cable Path Detector, and the RDCD-Ⅲ/RC11 Cable Fault Locator.

The output voltage of the RDCD-523W cable sheath fault locator is 0~10kV adjustable, which is suitable for the cable sheath handover test and preventive test of the cross-interconnect system and the fault location of the cable sheath (with step voltage positioning method). The instrument can quickly and accurately find the cable sheath ground fault, high leakage current and other hidden dangers of the 10kv-500kv single-core and three-core high-voltage and ultra-high-voltage cable. At the same time it can conduct 5kV~ 10kV DC high voltage withstand test on the high-density polyethylene and polyvinyl chloride cable sheath for 1 minute. It is a special instrument necessary for cable equipment maintenance of 10k V ~ 500kV single-core and three-core high-voltage and ultra-high-voltage cable operating units, ultra-high-voltage cable engineering companies, and various power transmission and substation engineering companies.

It uses an industrial-grade 12.1inch touch-screen computer with a simple operating software interface to achieve human-machine interactive testing. It adopts industrial-grade integrated circuits and components and is equipped with a large-capacity lithium-ion battery for stable and reliable performance and convenient use.

It is mainly used for comprehensive testing of cable fault point location, identification, path and depth. With precise positioning of low-resistance faults to ground, detection of faulty or operational cables, automatic impedance matching, multiple detection modes, it is suitable for the detection of various cables. Multi-antenna, multi-channel, directly display the depth of the buried cables. With current measurement function and the built-in ohmmeter to measure loop resistance.

The TAG7000B Non-Contact Electroscope offers safe, hands-free voltage detection from 380V to 500kV, with a red LED and buzzer alarm for clear alerts. Its IP65 rating and telescopic rod make it versatile for outdoor and indoor power line inspections, a vital tool for maintenance professionals.

The high-voltage pulse generator is mainly used to quickly detect cable faults of 35kV and below. It integrates high-voltage power supply, pulse energy storage capacitor, discharge ball gap and sampler.
Simple wiring, easy to operate, safe and reliable. It has functions such as overcurrent, overvoltage and overheating. It is with zero start protection, high voltage side measurement, real-time display of residual voltage. The meter displays the current and voltage pointer in real time which is intuitive and reliable.
