The Cable Fault Tester is a comprehensive set of equipment. It is used for the test of open, short-circuit, grounding, low-resistance, high-resistance flashover and high-resistance leakage faults of power cables, as well as the accurate testing of open-circuit and short-circuit faults of coaxial communication cables and local telephone cables. It can also test the cable path, buried depth, and radio wave velocimetry, verify the cable length, etc., and can establish cable files for daily maintenance and management.

The instrument adopts a variety of detection methods and applies the achievements of contemporary advanced electronic technology. Using computer technology and microelectronic technology, it has the characteristics of high degree of intelligence, complete functions, wide range of use, accurate testing and convenient use.

The cable fault tester can be used for open-circuit, short-circuit, ground fault, as well as high-impedance leakage faults and high-impedance flashover faults of cables. Features: It is suitable for testing various types of communication cables and power cables with different levels of voltage. The instrument is fully functional, and the test fail-safe is fast, fast and accurate; And equipped with menu display operation function, no need for special training for operators; It has the functions of wave opening, parameter storage and recall.

In addition to the above functions, the cable fault tester also has a dual trace display function, which can compare the test waveform of the faulty cable with the normal waveform, which is conducive to further judgment of the fault.

Bridge of cable testing equipment: An instrument that measures various quantities (such as resistance, capacitance, inductance, etc.) by comparative method.

Insulation resistance tester for cable testing equipment: commonly known as shaking meter, most of the megohmmeters are powered by hand-cranked generators, so they are also known as shaking meters, which are mainly used to check the insulation resistance of electrical equipment, household appliances or electrical circuits to the ground and between phases, so as to ensure that these equipment, electrical appliances and lines work in a normal state to avoid electric shock and equipment damage and other accidents!

Tensile machine for wire and cable testing equipment: a mechanical afterburner testing machine used for static load, tensile, compression, bending, shearing, tearing, stripping and other mechanical properties tests of wires and cables!

Aging box of cable testing equipment: used to test the ozone aging resistance of rubber and its products.

Projector of cable testing equipment: An optical projector specially designed for the measurement of wire and cable insulation and sheath thickness, that is, a precision instrument that uses the optical projection method to project the cross-sectional profile of the insulation or sheath of the tested cable on the screen, observes and aims, and uses the micrometer station to measure the length without force!

Spark testing machine for wire and cable testing equipment: the first testing equipment placed in the take-up part of wire products during the production of wires and cables, the main function is to use frequency and voltage to detect whether the wire products have copper leakage, skin impurities, insulation withstand voltage, etc. The spark testing machine will periodically load the set voltage value onto the insulating wire according to a certain law, and the conductor part is grounded, so that a voltage difference is formed between the conductor and the insulating surface, so that the insulation layer can be detected whether it is defective, so that the wire and cable products are qualified to leave the factory withstand voltage testing machine

It is mainly used for the withstand voltage test of polyethylene insulated power cables, and can also be used for the insulation withstand voltage test of large power transformers.

Thickness gauge of cable testing equipment: It is an instrument used to measure the thickness of materials and objects.

Wire and cable testing items include: conductor resistance, insulation resistance, insulation thin point thickness, tensile strength change rate, elongation at break after aging, tensile strength after aging, elongation at break before aging, tensile strength before aging, withstand voltage test, insulation thickness, elongation change rate, external dimensions, printed signs.

Hello: cable tester, also known as cable fault tester, is used to detect cable faults, instrument types, instrument models have increased a lot, now in the domestic cable fault test instrument market, the most advanced instrument types, instrument names are varied, in addition to our common cable fault tester, the market has appeared directly buried cable fault tester, street lamp cable fault tester, medium and low voltage cable detector, cable grounding fault tester, mine cable fault tester and so on.

Global Wire & Cable Portal** - Cable Network.

There are usually two ways to withstand the voltage of power cable experiments, series resonance is what we call AC resistance, to achieve, there is another way to achieve the DC withstand voltage, which usually reaches 35kV

There is basically a material instrument (for conductors), a thickness meter (to measure the thickness of the insulation layer), and a resistivity meter.

Physical test: tensile stripping machine, lead bending test.

Environmental Testing: Aging Tester.

Cable inspection typically requires checking the following items:

Visual inspection: check whether there are scratches, wear, deformation, cracks and other physical damage or chemical corrosion on the surface of the cable sheath, and check whether the identification, nameplate and length of the cable meet the requirements.

Insulation Resistance Test: Using a resistance tester or insulation tester, measure the resistance value of the cable insulation layer to evaluate the insulation state of the cable.

Wire-to-wire resistance test: Use a test instrument such as a multimeter to measure the resistance value between wire-to-wire in the cable to determine whether the conductor of the cable is damaged.

Dielectric damage detection: use AC withstand voltage tester to test the insulation damage of the cable under normal working voltage, such as flashover discharge.

Steel wire armor detection: check whether the cable steel wire armor is complete, whether there is broken wire, rust, loosening and other phenomena.

Cable gland and terminal detection: check whether the contact between the cable connector and the terminal is good and whether the fastening is firm, and check whether the waterproof and anti-corrosion measures at the cable gland and terminal are in place.

Reliability test: Evaluate the reliability and performance of the cable by conducting high-voltage tests, heat resistance tests, cold resistance tests and other tests.

These test items can effectively evaluate the safety and reliability of cables, prevent cable accidents, and ensure the stable operation of the project.
