24KV 36KV Manually Operated Aerial Switch (IACM)

1.Overview
IACM-12- 36/400-50A is a new type of load switch designed and manufactured with advanced technology. This load swichiscomposed of an iso lation gate knife, arc rod, etc. When the current is interupted, the arc rod stores enery and moves quicky to open the circuit.lengthening the arc and cooling it with airextinguish it. The speed of the arc contact movement is not affected by the speed of manual operation andit has the principle of rapid arc extinguishing after reaching safe break with the advantages of simple structure, less maintenance work, strong arcextinguishing ability. high insulation level of the break, and high reliability.reaching the levelof simlar products at home and abroad. The swich can beused for radia, ring network lines and transformer circuits (used with high voltage curent limiting fuses short circuit protection) or for current freeisolation. This series of switches is designed and manufactured in accordance with the following standards:
IEC 60265-1 High-Voltage Switches Part 1: Switches for Rated Voltages Above 1 kV and Less Than 52 kV
IEC 62271-1 High-voltage switchgear and controlgear -Part 1: Common specific ations for alterating current switchgear and controlgear
IEC 62271-103 HIGH VOLTAGE SWITCHGEAR AND CONTROLGEAR – PART 103: SWITCHES FOR RATED VOLTAGES ABOVE 1 KV UP TO AND INCLUDING 52KV
