Cable Testing Equipments

Digital cable fault locator is a precision instrument, easy to use, which provides spontaneous display of the location of break in pair wires and cables. Unlike conventional cable fault locators in which a lengthy procedure of obtaining a null point in a galvanometer and then computing the faulty length of cable is to be gone through, here the faulty cable is just to be connected, one setting to be made and location of fault in terms of total length directly read on display upto a resolution of 0. 1%.
Display: 3½ digit bright LED display.
Resolution: 0. 1%.
Power: 220 V AC± 10%.

HV Spark Tester is designed for checking the quality of pvc coated or insulated wire online manufacturing unit. The insulated wire is passed through brass ball chains which are carrying high voltage. If any pinhole or fault comes in insulated wire, the spark develops and electromagnet counter counts the fault. The spark tester is therefore necessary for every cable manufacturing unit. Our spark testers upto 15 KV are air cooled (there after for higher capacity transformer is oil cooled and control panel air cooled).

Digital Capacitance Unbalance Meter (Digital RC Unbalance Meter)
Digital R-C Unbalance Meter For CO
Digital R-C Unbalance Meter for communication cables. It has been shown that there are some losses resulting from the cable manufacturing process which affects the intelligibility of the telephone circuit. These are caused by the unbalances in the cable pairs which not only affect the uniformity of the line but it also makes the lines susceptible to induction from other sources such as power line harmonics, ground line, voltage noise, etc.
The degree of balance in communication circuit determines how susceptible the circuit will be to induce noise voltages. This R-C Unbalance Meter will be very useful for direct measurement of capacitance unbalances in the cable pairs. The instrument can measure resistance unbalance also. The pairs can be tested for capacitance and resistance unbalances in different configurations which are selected by a rotary switch. The Unbalance Meter is designed in such a way that it will not be sensitive to the effect of indirect couplings. This Digital R-C Unbalance Meter meets the long felt requirement of telecom cable industry. The instrument confirms to international specifications and yet is priced less than half of comparable instruments available in the international market.

Thermoplastic and elastromeric insulation & sheath exposed to heat are subjected to many types of physical and chemical changes. The severity of exposures, both in temp & time, determines the extend & type of change that takes place. This test makes an assessment of change in tensile strength and elongation of materials on subjecting them to accelerated ageing in air.
