Outdoor Switch-disconnector(IACM)LBS-12~36/400-50
1. Overview
LBS-12~36/400-50A (IACM -12~36/400-50A) is a new type of load switch designed and manufactured with advanced technology. This load switch is composed of an isolation gate knife, arc rod, etc. When the current is interrupted, the arc rod stores energy and moves quickly to open the circuit, lengthening the arc and cooling it with air extinguish it. The speed of the arc contact movement is not affected by the speed of manual operation, and it has the principle of rapid arc extinguishing after reaching safe break, with the advantages of simple structure, less maintenance work, strong arc extinguishing ability, high insulation level of the break, and high reliability, reaching the level of similar products at home and abroad. The switch can be used for radial, ring network lines and transformer circuits (used with high-voltage current limiting fuses short-circuit protection) or for current-free isolation. 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 alternating 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 52 KV
2. Environmental Conditions for Use
Ambient air temperature for use: ≤40 ℃/-30 ℃, with a daily temperature difference not exceeding 32K; Altitude:≤2000m Air pollution level: Grade IV to GB5585 Article Maximum wind speed: Wind pressure not exceeding 700Mpa Seismic capacity: Earthquake intensity not 8 degrees Load: Ice thickness not exceeding 10mm
