high-accuracy JLSZV-6, 10 three-phase dry type outdor combined transformer

imported resin, long-life
outdoor and high-accuracy

Description

This model combined transformer is one kind of outdoor energy metering device, it is one newest dry type power metering tank specially designed for non-oil renovation of power network, which replaces old type oil-immersed product. This product owns many advantages as small volume, large capacity, steady insulated performance, anti-pollution and non-require maintenance etc.

This product is composed of two sets single-phase wholly insulated voltage transformers, forming three-phase “V/V" wiring mode, and two current transformers are separately series connected to A and C phase, moreover, the secondary coil of current transformer owns tap, through which gains different current changing and has metering more accurate. For the super quality anti-aging insulated material is adopted inside this product, and its outer appearance is vacuum-cast by outdoor epoxy resin, doesn't need any special maintenance, so it just needs regular cleaning of appearance pollution.
