Summary
LB3-110 current transformer (LB3-110) is a kind of outdoor fully-enclosed capacitance oil-paper insulated current & electricity measuring and relay protection device used in alternative current (AC) power system with maximum voltage of 126KV and rated frequency of 50Hz or 60Hz.
LB3-110, with 4 pieces of secondary windings, adopts secondary measuring windings made of highly magnetism-conductive microcrystalline alloy, able to guarantee the measuring precise to Level 0.2 or 0.2S.
LB3-110 has fully-enclosed stainless steel metal expander and the sealing adopts imported cushion. The shell adopts new techniques and new materials (such as hot dipped galvanized and stainless steel standard parts), keeping the whole machine free of corrosion. The reasonable structure, advanced techniques and new materials enable the product run reliably, safely and durably.
Working Environment
Ambient Temperature: Max. Atmospheric Temperature: +40℃; Min. Atmospheric Temperature: -30℃; Daily average atmospheric temperature: ≤+30℃ (able to provide special products)
