CaSi Cored Wire Resistance And Precautions

Suitable for AC rated voltage 0.6/1kv and the following fixed-laying power transmission line or movable electric appliance connection cable, products with heat-resistant radiation, cold, acid and corrosive gases, waterproof and other characteristics, cable structure soft, convenient radiation, high temperature (cold) environment under stable electrical performance, anti-aging performance, long service life, Widely used in metallurgy, power, petrochemical, electronics, automotive manufacturing and other industries. This approach has changed little over the decades.CaSi Cored Wire 

This method is very convenient for short circuit fault and low resistance fault detection. The bridge method is to use the bridge balance, corresponding to the product of the arm resistance is equal, and the length of the cable and the resistance is proportional to the principle of testing.CaSi Cored Wire

The low voltage pulse method is also called time Domain Reflection method (TDR), which refers to the independent measurement of the low resistance of the cable and the fault of the circuit breaker without passing the high pressure impactor. The impulse voltage sampling method, also known as Impact High voltage flashover method, is a test method for measuring high resistance leakage and flashover fault. The cable breakdown is first penetrated by a DC or pulse high voltage signal, and then measured by recording the discharge pulse at the measuring point and the fault point.CaSi Cored Wire

The pulse voltage method mainly includes two methods: DC High Voltage flashover (direct Flash method) and impact high pressure flashover (Flash method).CaSi Cored Wire

This method is generally used to detect low resistance faults. Its principle is: 1kHz audio signal generator to the test cable to inject audio current, so that the cable emits electromagnetic waves, the ground to receive electromagnetic signals, and amplification, and then send to the ear machine or indicator instrument, according to the sound strength or indicating the size of the instrument value to determine the location of the fault point.CaSi Cored Wire
