Are designed for checking the quality of PVC coated wires during manufacturing at shop floor. The PVC wire is passed through brass ball chains which carry high voltage. If any pin hole comes in PVC, a spark develops and electro magnetic counter counts the fault. The spark tester is necessary for every cable manufacturing unit.
The equipment uses a high frequency oscillator circuit for rising frequency to search the fault at low leakage current and signifies that as a fault, he fault is displayed to the operator by means of a visual indicator and audible. The equipment can test a variety of cable at various voltages for which KV setting & sensitivity setting is provided.
The different Spark Testers manufactured are of:
- Power Frequency (50Hz)
- High Frequency (500 Hz/3000Hz-5000Hz)
The Power Frequency Spark Tester is a Conventional Spark tester, being used by wire and cable manufacturers, since the start of cable manufacturing. These spark testers hold the efficiency gradient of approximately 85%. They leave a burn mark on the cable/wire at the point of fault, which makes it easier to locate and isolate / mend the fault.
- Suitable up to 200 Meter per minute
- Easy to operate
The High Frequency Spark Tester is used for High speed precision jobs where the requirement is of seizing the maximum number of faults. These Spark Testers can be used for high speed extruders and high speed Recoiling processes. The efficiency of a high Frequency Spark Tester is upto 95%-98%. This efficiency is much better than conventional spark tester.
SPECIAL FEATURES
- High Speed operation upto (1000 m/min).
- Much smaller and higher unit.
- Computer Interface facility available.
- Efficiency of operation upto 95%.
- Suitable for extruder and recoiling.
- Short Circuit Protected
