Recent statistical studies show that approximately 90% of the actions of expulsion fuses (cut-outs) in leads airline electrical distribution, occurring in response to transient faults such as atmospheric storms, contact with tree branches, etc., likewise it is known that the cost incurred in the replacement of cast expulsion fuse approaches the cost of a cut-out again.
The automatic INAEL sectionalizers are an effective and radical solution to protect leads and branches in overhead distribution lines, providing an economical solution that ensures effective isolation of a referral in the case of a permanent local failure, remaining inert to transient faults mean about 90% of the faults occurring in the electrical distribution lines.
INAEL sectionalizers range is formed by:
- Models of the series SEIN, single-phase type for tensions of 15 kV, 24 kV and 36 kV with range of currents from 8 To to 140 To and number of lacks from 2 to 3 configurable ones.
- Models of the series SIT, three-phase type for tensions of 15 kV, 24 kV and 36 kV with range of currents from 8 To to 140 and number of lacks from 1 to 4 configurable ones. ·
- Models of the series SPIN, three-phase and / or single-phase configurable type for tensions of 15 kv, 24 kV and 36 kV with range of currents from 5A up to 230A, number of lacks from 1 to 99, parameters of programmable functioning in local and remote way and integrable in systems of communication SCADA.
