Current Transformer
General description:
LVB series of oil-immersed inverted-type current transformer for the inverted fully enclosed structure.
Mainly by the expander, oil conservator, a winding, body, porcelain sets, base and junction box and other components.
The maximum average relative humidity of 95% (at 25 ºC); the maximum wind speed: 35m / s; the atmosphere; the average daily temperature is not higher than +35 ºC; the maximum temperature: In no serious impact on transformer insulation pollution and erosive, explosive media; seismic intensity of not more than 9 degrees in the region. According to the user to use specific conditions for targeted design.
Features:
1, the main insulation for the oil-paper capacitor structure, the use of imported materials, products, excellent insulation properties;
2, has a reliable dynamic thermal stability;
3, the product casing with multi-screen structure, the internal and external electric field distribution;
4, the main components for the cast aluminum alloy material, the use of welding welding, product corrosion and sealing performance;
5, the second terminal with Phoenix terminal blocks, user wiring convenience;
6, reliable operation, easy maintenance.
