SIBA HHP High Voltage (HV) Fuses - European Standard for Overhead Lines

SIBA HHP High Voltage (HV) Fuses - European Standard for Overhead Lines

High voltage fuse-links with overhead line connectors - provide high voltage overhead lines with fuse protection on pole mounted distribution transformers. SIBA high voltage overhead line fuses are supplied as a set consisting of a high voltage fuse-link and a set of contacting armatures.

A tee-off connection for the installation of such a set provides the possibility to isolate the trans-former from the overhead service line. Isolation can be achieved with the overhead line alive and service or modification work on the transformer circuit will not cause interruption of high voltage electricity supply to theoverhead line. The HV transformer will only be disconnected on the low voltage side.

SIBA HHP high voltage fuse links are designed to provide bursting protection of the high voltage transformer. The time-current characteristic of the high voltage fuse-links matches with the maximum withstand capability of standard pole mounted transformers under fault conditions. Through appropriate design of the fuse-link melting elements, the overhead line fuse links are especially suitable for high voltage overhead lines, which are subjected to lightning strikes, because the short current peaks of such strikes will not cause opening of the fuse-link. The fuse-links with a rated voltage 24kV are suitable for networks with service voltages 10kV to 24kV.

SIBA HV Fuses : SIBA high voltage fuse links for reliable circuit protection of air, gas and oil insulated high voltage switchgear and transformers operating at 3.3kV, 6.6kV, 11kV, 20kV and 33kV voltages - this includes back-up fuses, general purpose fuses, motor fuses, capacitor fuses, overhead line fuses and full range high voltage fuses for switchgear and transformers. Also - British Standard (BS2692), German DIN Standard, North American Standard and French Standard high voltage fuses.
