Product successfully added to the Quote List

SNV-EFI earth fault indicator, it Widely used in various ring cabinets, high/ Medium or low -voltage switch gear and cable branch box in power system, can accurately and reliably detect the fault section and fault type ofpower grid in the Low/medium voltage network. The use of cable type grounding fault indicator is an efficient way to check cable fault, and is an effective way to improve the operation level of distribution network and theefficiency of fault handling. The design uses electromagnetic induction, and single chip microcomputer control technology to make fault alarm with high accuracy and strong anti-interference ability

Suspension clamp PS 1500 is designed to suspend LV ABC with insulated neutral messenger of cross-section between 16 mm² and 71,5 mm². It is resistant to environmental and mechanical effects and UV radiation since it is made of material of high tensile strength and stable structure. Suspension clamp allowsturning angle of 30/60°. It is installed using no tools and does not contain parts which can fall off during installation.

Overhead type Line Fault Indicators is based on the sensor that through Current Transformer (CT) to get the line current signal through smart processor and calculation to judge the short circuit or ground fault. The sensor ablet to warn the user through red LED equipped. It is beneficial for power management to find the fault points and to help in restoring the faulty line faster.
